Description

A solar greenhouse gable roll quilt mechanism

technical field

The utility model relates to a rolling quilt mechanism for a solar greenhouse, in particular to a rolling quilt mechanism for a gable wall of a solar greenhouse which can use a deceleration motor to roll up and lay down the greenhouse insulation quilt. The solar greenhouse gable rolling quilt mechanism can roll up the insulation quilt from top to bottom, and then lay it from bottom to top, so it can adapt to thicker insulation quilts, and the insulation quilt is rolled up and located at the front foot of the greenhouse, so it can be greatly improved. Increasing the lighting area of the greenhouse can also reduce the load on the greenhouse frame and greatly improve the temperature and light performance of the solar greenhouse.

Background technique

At present, domestic quilt machine manufacturers and products are very rich, but the quilt machines produced are mainly divided into the following three forms according to the installation and operation methods:

One is the rear wall fixed greenhouse roller blind machine, also called rear scroll type, rear pull type or pull wire type greenhouse roller blind machine. This type of roller blind machine is the earliest on the market. It is composed of three parts: the main engine (composed of a gearbox and a motor, the same below), a rolling rod and a column (or bracket), and can be rolled up for greenhouse insulation within 100 meters. shop. The working principle of this roller blind machine is to rotate the roll rod through the main machine, the roll rod is wound around the stay rope, and the stay rope pulls the grass thatch or heat preservation quilt. When the grass thatch or thermal insulation quilt is put down, it will slide down along the slope of the shed with its own weight. It is characterized by low cost and can adapt to thicker insulation quilts; the disadvantage is that it is easy to cause the danger of involving the operator due to too many pull ropes.

The second type of greenhouse rolling machine is the self-propelled shed surface, also known as the forward-bending outrigger greenhouse rolling machine. It is composed of three parts: main machine, support rod and rolling rod, and can be rolled up for greenhouse insulation within 100 meters. According to the different supporting rods of the greenhouse rolling machine, it can be divided into a bracket type greenhouse rolling machine and a track type greenhouse rolling machine. The former's supporting rod is composed of a vertical rod and a supporting rod. The support rods of the latter consist of track-type sliders formed by reinforced tripods. The basic working principle of the self-propelled greenhouse rolling machine is to rotate the rolling rod through the main machine, and the rolling rod directly pulls the grass thatch or insulation quilt, and both pulling and releasing are supported by power. It is a type of rolling machine that is widely used at present. . The mechanism is characterized by high safety and stable performance; the disadvantage is that since the geared motor is located in the middle, a fixed heat preservation quilt is used for heat preservation in the middle without the drive shaft, which has a great impact on the lighting of the greenhouse. And the cost is more than 2 times higher than the back wall type.

The third type is the side-rolling quilt rolling machine, which is composed of three parts: the main machine, the support rod, and the rolling rod, and can be used for rolling the greenhouse insulation quilt within 70 meters. The roll is located on the side of the greenhouse by the supporting rod of the mechanism, so the overall structure is simple and the operation is safe. The characteristic is that the mechanism is simple and the cost is moderate; the disadvantage is that the adaptable length is small, and the rolls are not neatly laid during operation.

To sum up, there are several problems that need to be solved urgently in the existing various roll-up institutions:

(1) The influence of thermal insulation quilts on the lighting of greenhouses

The existing roll-up machines all adopt the method of rolling up and laying down the insulation quilt, that is, relying on the roll rod or pull rope to roll up the insulation quilt from the foot of the greenhouse roof, and then place the insulation quilt on the roll. on the roof of the greenhouse. In practice, in order to prevent the insulation quilt from falling from the greenhouse roof, the insulation quilt rolls are generally placed 1.5 to 2 meters close to the greenhouse roof, and some are even more. For the 9m to 10m lighting surface of a general solar greenhouse, this part of the shading accounts for 15% to 20% of the total lighting area, thus greatly affecting the lighting of the greenhouse.

(2) Influence of self-weight load of thermal insulation quilt and quilt mechanism on greenhouse structure

The existing thermal insulation quilt rolling mechanism adopts the unrolling method, that is, when the thermal insulation quilt is rolled out, it will roll down from the ridge of the greenhouse to the front foot of the greenhouse by its own weight, and it will be placed on the ridge of the greenhouse when it is rolled up. . This makes all the loads of the thermal insulation quilt and its rolling mechanism act on the ridge of the greenhouse for a long time, which is unfavorable for the safety of the greenhouse structure and the stability of the skeleton structure.

(3) Except for the first type of back wall type, the existing roll-laying mechanisms cannot adapt to thicker insulation quilts, thus limiting the use of insulation quilt materials with better insulation effects but heavier dead weight in practice. In addition, although the forward-bending outrigger type and the track type can adapt to thicker insulation quilts, they have complex structures, high cost, and still have the above two structural shortcomings, which in turn restrict the further improvement of greenhouse building performance to a certain extent. improve.

Contents of the invention

Aiming at the defects or deficiencies of the existing solar greenhouse roll-up mechanism, the purpose of this utility model is to provide a solar greenhouse gable roll-up mechanism, which can rely on the greenhouse gable without adding additional mechanisms (such as forward-bending or extending arms or In the case of track), the insulation quilt can be laid up and rolled down, and the insulation is rolled up and placed at the bottom of the front foot of the greenhouse.

In order to realize above-mentioned task, the present invention takes following technical solution:

A solar greenhouse gable rolling mechanism, comprising a solar greenhouse gable, characterized in that gable channel steel guide rails are arranged on the solar greenhouse gable, and there are gable channel steel upper rails between the gable channel steel guide rails; inside the gable channel steel guide rails are Cylindrical roller bearings, there is a reducer bracket on the cylindrical roller bearings, the reducer bracket is connected with a deceleration roll-up machine, the output shaft of the deceleration roll-up machine is connected with the roll-up shaft through a coupling, and there is a transmission on the roll-up shaft A steel cable, one end of the transmission steel cable is connected with the upper gear of the gable channel steel.

Another feature of the utility model is that the decelerating quilt rolling machine A is an integrated machine composed of a reducer and a motor.

The solar greenhouse gable rolling quilt mechanism of the utility model has a reasonable structure, does not increase the cost compared with the existing solar greenhouse, and can greatly improve the heat storage and heat preservation level of the greenhouse. The technical effects brought about are:

The rolled quilt method is adopted, and the rolled insulation is finally placed on the front foot of the greenhouse, which is similar to the roll-up and bottom-laid method of other insulation quilts (the rolled insulation is finally placed on the ridge of the greenhouse). Ratio, the more upwards the rolling quilt machine runs, the smaller the torque required for the structure, so the performance of the rolling quilt mechanism is better, and thicker and better thermal insulation quilts can be used. It provides technical and structural space for the further upgrading of thermal insulation quilts.

The folded insulation is finally placed at the front foot of the greenhouse. The structure change has greatly improved the structure and lighting performance of the greenhouse. In terms of greenhouse structure, due to the heavy weight of the insulation quilt and its rolling mechanism, it can usually reach 5-10 tons, and the heaviest can even reach 40 tons, so it is a large concentrated load for the structure. However, when the solar greenhouse gable rolling quilt mechanism of the utility model is adopted, this part of the load no longer acts on the roof ridge of the greenhouse, but acts on the ground at the front foot of the greenhouse. Therefore, the structure of the greenhouse is safer and more reliable, and the load is also less when calculating the structure. It will reduce a lot, and then the cost of the greenhouse structure can be reduced without reducing the safety of the structure.

The rolled insulation quilt is finally placed on the ridge of the greenhouse, and in practice, in order to prevent the insulation from being dropped on the back slope of the greenhouse, the insulation quilt is generally placed at a distance of 1.5 meters to 2.0 meters from the ridge of the solar greenhouse. Both the volume itself and the 1.5-2.0-meter front lighting surface covered by insulation will seriously affect the lighting of the solar greenhouse. Moreover, the length of the lighting surface of a general solar greenhouse is about 9.0 to 10.0 meters. Therefore, this part of the shading accounts for about 20% of the total, which is extremely unfavorable to the lighting of the solar greenhouse. The solar greenhouse gable roll quilt mechanism of the utility model adopts the mode of rolling down and laying up, which can completely overcome the defects of the original mechanism. Therefore, it provides a large technical space for improving the lighting performance of the solar greenhouse, and has great application value.

Detailed ways

Referring to accompanying drawings 1 to 3, this embodiment provides a solar greenhouse gable roll-up mechanism, including a solar greenhouse gable J, on which a gable channel steel guide rail E is arranged, and between the gable channel steel guide rails E are fixed The upper gear H of the gable channel steel; there is a cylindrical roller bearing G in the gable channel steel guide rail E, and there is a reducer bracket F on the cylindrical roller bearing G. The output shaft of A is connected with the quilt shaft D through the shaft coupling B, and the transmission cable C is arranged on the quilt shaft D, and one end of the transmission cable C is connected with the upper gear H of the gable channel steel.

Among them, the role of the deceleration quilter A is to provide output torque; the role of the coupling B is to connect the quilter shaft D and the deceleration quilter A, so as to facilitate the deceleration and replacement of the quilter A later. The quilt shaft D is used to unfold or roll up the insulation; the transmission cable C is used to guide the quilt shaft D to roll upward; the gable channel steel guide rail E is installed on the gable J of the greenhouse through embedded parts The top is used to fix the deceleration quilter A, and also provides guide rails for the transmission cable C on the gable; the cylindrical roller bearing G is used to connect the deceleration quilter A and the quilter support E, and provide The deceleration coil is supported by the machine A; the upper gear H of the gable channel steel is used to fix the fixed end of the transmission cable C.

In this embodiment, the deceleration rolling machine A is an integrated machine composed of a reducer and a motor.

Its installation process is as follows:

First, install the gable channel steel guide rail E on the gable J of the solar greenhouse through embedded parts. The gable channel steel guide rail E is composed of two channel steels. One end of the channel steel upper gear H is connected with the guide cable C of the coiling machine;

Secondly, install the cylindrical roller bearing G inside the gable channel steel guide rail E, and at the same time, fix the deceleration quilter A through the reducer bracket F; finally, connect the output shaft of the deceleration quilter A to the quilt shaft through the coupling B d.

When running, turn on the decelerating quilt machine A, and under the traction of the guide cable C, the decelerating quilt machine A unfolds the insulation quilt from bottom to top along the gable channel steel guide rail E, and the insulation quilt is rolled and fixed under the front corner of the solar greenhouse , during the unfolding process, when the thermal insulation quilt is rolled up from bottom to top, the thermal insulation quilt roll gradually decreases, and the corresponding load also gradually decreases. When it reaches the top of the greenhouse, the load is the smallest. It gradually decreases from bottom to top, which is conducive to the normal operation of the heat preservation quilt. Moreover, due to the use of the guide cable C, there is a driving force in the process of rolling up and down the thermal insulation quilt, so the thermal insulation quilt can cover the back slope of the solar greenhouse at the same time, thereby realizing a full coverage of the solar greenhouse, which can greatly improve the thermal insulation performance of the solar greenhouse.

When the thermal insulation quilt needs to cover the solar greenhouse, the deceleration roll quilt machine A outputs an upward rolling torque, and the roll quilt shaft D can roll the quilt at the same time, and lay the thermal insulation quilt on the solar greenhouse from the bottom of the solar greenhouse along the gable channel steel guide rail E on the front roof. When the solar greenhouse needs to turn on the heat preservation quilt for daylighting, the deceleration rolling quilt machine A can reversely output the torque, and the quilt shaft D can roll the heat preservation quilt, and the heat preservation quilt can be smoothly released from Roll it up and down, and finally place it on the bottom of the front corner of the greenhouse.
