Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, in particular to a rice seedling pulling machine. Background Art

[0002] A vine puller is a type of agricultural machinery mainly used for processing crop stems. It is used for pulling and crushing vines in agricultural planting. Vine pullers are widely used in various agricultural scenarios, especially in greenhouses. They can effectively process the stems of crops such as tomatoes, potatoes, cucumbers, peppers, and strawberries. The volume of the crops processed by the vine puller will be reduced to about 20% of the original volume. Through the cooperation of an automated feeding device and a crushing mechanism, the vine puller can realize the automatic transportation, gathering, and crushing of crop stems, thereby effectively replacing manual labor. Compared with the traditional manual vine pulling method, the vine puller can quickly process a large number of crop stems and realize efficient and automated processing of crop stems, thereby significantly improving the processing efficiency of crop stems and reducing labor costs and time costs.

[0003] Chinese invention patent number 202410153991.0 discloses a rice vine pulling machine comprising a crawler system with a carrier mounted on top, a crushing bin body fixedly connected to the top of a crushing bin support frame, and a flexible feeding assembly at the bottom of a feeding bin. The machine comprises a feeding bin, a spiral feed roller, a conveyor belt support frame, and a stalk conveyor belt. During use, the crop stalks are evenly stacked on the stalk conveyor belt. A first hydraulic motor on the bottom frame continuously rotates the conveyor belt reel, which winds up the stalk conveyor belt, pulling the crop stalks upward. The conveyor belt support frame on the movable plate raises the bottom of the stalk conveyor belt, allowing the crop stalks to enter the feeding bin. The spiral feed roller has a symmetrical spiral structure on its exterior that gathers the crop stalks toward the center and delivers them to the bridge bin, achieving automated feeding and resolving the time-consuming, labor-intensive, and costly issue of rice vine pulling.

[0004] Although the above-mentioned vine pulling machine can improve the processing efficiency of crop stems to a certain extent, it is gradually discovered during use that it still has the following defects:

[0005] (1) It is impossible to quickly disassemble and replace the conveyor belt reel and switch the working position of the conveyor belt support bracket. When using it, it is necessary to first pull the stalk conveyor belt out from the conveyor belt reel, pass it around the conveyor belt support bracket and lay it on the ground, and then lay the crop stalks on the stalk conveyor belt. After completing the processing of one row of crop stalks, the above steps are repeated when processing the next row of crop stalks. In this way, the stalk conveyor belt needs to be pulled out and laid frequently, and each time the stalk conveyor belt needs to be pulled out and laid before the crop stalks can be laid on the stalk conveyor belt. The operation is cumbersome, inconvenient, time-consuming and labor-intensive.

[0006] (2) The safety net installed at the feeding bin can provide a certain degree of safety protection, but the top and side safety nets are fixed to the equipment frame and do not have the function of folding and storing. Therefore, the horizontal width of the equipment is greatly increased. The equipment is large in size, occupies a large area, and has poor flexibility. It is very inconvenient to move around in the greenhouse and is prone to scratches and collisions with facilities in the greenhouse. The passability is poor and it cannot be used in greenhouses with limited space.

[0007] (3) The feeding bin and the crushing bin are connected through the bridge bin, and the feeding structure composed of the driving shaft, the driven shaft, the bridge crawler and the feeding plate is used to compact and push the material. However, the connection between the spiral feeding roller and the crushing knife roller assembly is poor, and the pressing and feeding effects are not ideal. The material is easily wrapped around the bridge crawler and the feeding plate, resulting in material jamming and blocking.

[0008] (4) The crushing roller assembly, bridge crawler and spiral feed roller are all driven by the diesel power system assembly. The diesel power system has a high load, the crushing effect is not ideal, and the equipment failure rate is high and the service life is short;

[0009] (5) The adjustment effect of the material throwing distance and throwing angle of the discharge port is poor. When material blockage occurs, it is not convenient to conduct timely and effective inspection and dredging of the equipment. Summary of the Invention
