Description

A device for unclogging columbia legs and a wide-distance planter equipped with the device

technical field

The invention relates to a seeder, specifically a multi-row columbine leg wide-spacing seeder equipped with a columbine leg with a blockage remover, which is especially suitable for sowing soybeans and other crops with narrow row spacing in a wheat field with straw. use.

Background technique

At present, the seeders sold on the market can be divided into two types: single-row columbine legs and double-row columbine legs in terms of the layout of columbine legs. When sowing soybeans and other crops with narrow row spacing, congestion will be caused to varying degrees. Only by burning the straw can the seeds be planted smoothly. As we all know, burning straw not only pollutes the environment, affects traffic, but also endangers human health.

Contents of the invention

The purpose of the present invention is to overcome the defect that the above two types of seeders are easy to be blocked when sowing crops with narrow row spacing, and to provide a multi-row columbine-leg wide-space seeder that can sow smoothly without burning straw, which can solve the problem of The problem of blockage when sowing soybeans and other crops with narrow row spacing in wheat stubble fields with straw.

The scheme of the present invention is made up of frame, traction hook, ground wheel, seed box, fertilizer box, seed metering device, screw rod fertilizer divider, columbine leg column, ditch opener, pressing roller and columbine leg unblocking device, its structure The characteristic is that there are multiple rows of crossbeams on the frame, and there are multiple columbine legs on each crossbeam. The distance between two adjacent columbine legs on the same beam is several times wider than the original sowing row spacing, and the front and back are adjacent to each other. The relative positions of the two rows of columbine legs are staggered. The greater the distance between two adjacent columbine legs in the same row, the less congestion will be formed. The distance between two columbine legs is generally an integer multiple of the row spacing of the crops to be sown. The columbine leg column is fixed on the beam with "U" type bolts, and the position of the columbine leg can be adjusted according to the row spacing required by different crops. Whether row-spacing crops or narrow-row-spacing crops are planted, there will be no congestion.

The columbine leg unblocking device of the present invention, it is made up of unblocking device bracket, motor, bearing seat, transmission shaft, pressure sensor and weeding roller, and its structural feature is to be provided with motor on support, the below of motor is The end point of the bracket is provided with a bearing seat, the back of the bearing seat is provided with a pressure sensor, the bearing seat is provided with a bearing, the bearing is provided with a vertical transmission shaft, the upper end of the transmission shaft is connected with a motor, and the lower end is connected with a mowing roller. It is equipped with "V" shaped grass wings.

The present invention aims at the problem of concentrated distribution of straws in rows and ridges after wheat harvest. A blockager is provided on each columbine leg column, and a motor is provided on the blockager. The motor does not work continuously, and only when one or When one columbine leg is just in the area where the straw is more concentrated, due to the increase of the backward thrust of the mowing roller, the pressure sensor located behind the bearing seat is touched, and at this time the motor on the columbine leg is connected to the power supply on the tractor and starts to work. , through the transmission shaft to drive the suspended grass roller to rotate the grass, and spread the ridge-shaped straw sprayed by the harvester. When the straw is relatively sparse, the resistance of the grass roller decreases, the pressure sensor will cut off the power supply, and the motor will stop Work, at this moment, the weeding roller returns to the free rotation state from active weeding.

The screw fertilizer distributor of the present invention is provided with a screw at the fertilizer outlet at the bottom of the fertilizer box, and utilizes the ground wheel to drive the screw to rotate to realize uniform fertilizer distribution.

The ditch opener described in the present invention, it is to be provided with seed fertilizer separation plate at the rear part of ditch opener, the rear space of ditch opener is separated into two chambers of different sizes, and the wider chamber on the right side is In the seed bed room, there is a spherical lug at the seed inlet in the seed bed room. When the seeds fall quickly from the upper part, some seeds collide with the lug and are scattered throughout the seed bed room, which can increase the sowing width and increase the yield. , the narrower chamber on the left is the fertilizer sowing chamber. Due to the separation of the seed fertilizer isolation plate, there are two chambers, which realize the simultaneous sowing of seed fertilizers in different beds, and the separation of seed fertilizers, which is conducive to seed germination and growth.

Further detailed description will be given below in conjunction with the accompanying drawings.
