Description

A clamping type rapeseed naked seedling transplanting machine

technical field

The utility model relates to a transplanting machine for crop seedlings, which is particularly suitable for transplanting naked rape seedlings cultivated in the field and similar vegetable seedlings.

Background technique

In recent years, the acreage of rapeseed in my country has been increasing year by year, and it is the second largest oilseed crop after soybean. Rapeseed agronomy is divided into two categories: transplanting and direct seeding, and currently the dominant method is still transplanting. The existing transplanting method of rape seedlings is still mainly manual transplanting, which is labor-intensive, low in production efficiency, time-consuming and labor-intensive, which greatly increases the production cost of rapeseed and reduces the economic benefits of rapeseed production. It has become a bottleneck restricting the development of rapeseed production and has affected the further expansion of rapeseed planting area. However, there are few economical and practical rapeseed transplanting machines in China at present, and most of them are slideway transplanters suitable for pot seedlings. However, the cultivation cost of pot seedlings is high, and the comprehensive cost of using machines and tools is also high. Farmers welcome the transplanting of bare seedlings in field seedlings, but suitable transplanting machines are rare.

Contents of the invention

The technical problem to be solved by the utility model is to design an economical, practical and reliable transplanting machine suitable for transplanting naked rapeseed seedlings in view of the above problems.

In order to solve the above-mentioned technical problems, the rapeseed bare seedling transplanter of the present utility model adopts a suspension type, and is articulated on a three-point hydraulic suspension mechanism at the rear of the four-wheel tractor. The seedlings are fed manually, and the chain clamp planter is used, which is powered by the ground wheel drive device to realize semi-automatic mechanical transplanting. The ground wheel of the ground wheel driving device adopts rubber pneumatic tires, and the work is more reliable. The power obtained by the ground wheel is transmitted to the transmission shaft through the sprocket and the chain, and then transmitted to the planter by the transmission shaft through the sprocket and the chain. The planter is composed of a cantilever frame, a chain transmission mechanism, a seedling holder, a holder guide plate, a ditch opener, a seedling feeding hand seat, and a seedling tray. When working, the seedling feeder puts the seedlings on the rubber butterfly-shaped clamping claws of the seedling clamper, and the seedling clamper immediately enters the guard guide plate of the clamper to clamp the seedlings, when the clamping claws turn down to the lowest position , The seedlings are in an upright state. At this time, the clamper is separated from the guard guide plate, the clamping claws are released, and the seedlings are released in the planting soil ditch opened by the ditch opener. Work.

According to the size of the supporting four-wheel tractor and the requirements for the row spacing of rice seedlings, the planters of this transplanter can be arranged in two or more groups in parallel or in a staggered manner.

Detailed ways

Fig. 1 is a side view of a rapeseed bare seedling transplanter according to an embodiment of the present invention, and Fig. 2 is a top view thereof. This transplanting machine is made up of frame 2, power transmission shaft 3, planter 1, left ground wheel driving device 8, right ground wheel driving device 4, covering soil pressing wheel 5, left rowing device 10, right rowing device 11 forms. Frame 2 adopts three-point suspension mode to connect with four-wheel tractor.

Part is placed on the right side of the frame 2 is the right ground wheel driving device 4, its structure as shown in Figure 3 and Figure 4. It is fixedly connected with the frame 2 through the L-shaped clip 12, and the power obtained from the ground wheel 17 is transmitted to the transmission shaft 3 through the sprocket 15, the chain 14, the tension pulley 20, and the sprocket 13. The ground wheel 17 is a rubber pneumatic tire, which improves the reliability of the ground wheel drive. The device also has a safety protective cover 18 and a screw lift mechanism 19 that is used to adjust the height of the ground wheel and is made up of a screw rod and a nut. The left ground wheel driving device 8 has the same structure as the right ground wheel driving device 4, and the symmetrical part is placed on the left side of the frame 2.

Fig. 5 is a side view of the planter of the transplanter, and Fig. 6 is a partial view of it in A direction. It adopts U-shaped clips to be connected with the frame 2 through the cantilever frame 21. During work, the power transmitted from the ground wheel driving device is transmitted to the conveying mechanism of the planter through the transmission shaft 3, the sprocket 22, the chain 25, the tension wheel 34, and the sprocket 31, and the conveying mechanism of the planter is conveyed by the sprocket 30. Chain 28, sprocket wheel 26, rice shoot holder 32 forms. During operation, the seedling feeder feeds the seedlings into the rice shoot holder positioned at the top, and then the rice seedling holder enters the slideway formed by the left and right holder guard guide plates 35, 36 to clamp the rice shoots, and the rice shoot holder When forwarding to the lower vertical position, rice shoots are released in the soil ditch that ditch opener 33 leaves, and the soil-covering pressing wheel covers soil and suppresses simultaneously, and completes the seedling planting operation. The opener 33 is a wedge-shaped opener, which is connected to the cantilever frame 21 through a connecting plate 51. There are multiple rows of connecting holes on the upper part of the connecting plate for adjusting the trenching depth. The planter is also provided with a hand seat 23 and a seedling tray 27 for feeding seedlings, so as to facilitate operation.
