Description

Technical Field

[0001] The utility model relates to the technical field of green onion combine harvesters, in particular to a fan-shaped steering transmission device for green onion combine harvesters. Background Art

[0002] As an important economic crop in my country, green onions need to go through four links from planting to harvesting: seedling raising, transplanting and planting, field management and harvesting. Among them, the harvesting link is the top priority, and the efficiency of harvesting directly affects the final quality of green onions.

[0003] Green onions are usually cultivated on ridges that protrude from the ground. The onions are buried deep in the soil and have poor flexibility. If they are harvested mechanically, the onions will be easily damaged.

[0004] In the Chinese utility model patent application number 201520430142.1, a green onion harvester is proposed. The main problem in this patent is that after the green onions are lifted to a certain height by a conveyor belt, they are directly dropped into a stacking box. There is no transfer device between the end of the conveyor belt and the stacking device, and the distance between them is relatively large. During the transmission process, the green onions are very likely to fail to fall accurately and neatly into the stacking box, which can easily damage the green onions. Utility Model Content

[0005] The main technical problem to be solved by the utility model is to provide a fan-shaped steering transmission device for a green onion combine harvester, which is used to connect a straight conveyor belt and a stacking box, realizes the fan-shaped steering transmission of green onions, and solves the problem of green onions falling and being damaged due to excessive transmission gap.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A fan-shaped steering conveying device for a green onion combine harvester comprises two oppositely arranged fan-shaped mounting frames, each of which is equipped with a fan-shaped conveying belt, and an end-to-end flexible interlayer is fixed on the outer wall of each fan-shaped conveying belt, forming a conveying gap between the two flexible interlayers.

[0008] The top of each sector-shaped mounting frame is provided with an arc-shaped guide plate, and the upper end of each sector-shaped conveyor belt is provided with a plurality of guide wheels, and the side wall of each guide wheel is rolled and pressed against the arc-shaped guide plate.

[0009] The following is a further optimization of the above technical solution by the utility model:

[0010] The driving assembly comprises a driving cone shaft and a driven cone shaft. Both ends of the driving cone shaft and the driven cone shaft are rotatably mounted on a fan-shaped mounting frame. The fan-shaped conveyor belt is wound around the corresponding driving cone shaft and the driven cone shaft.

[0011] Further optimization: a plurality of brackets are fixedly installed on each of the fan-shaped conveyor belts, the spacing between every two adjacent brackets is the same, the number of brackets corresponds to the number of guide wheels, and each guide wheel is rotatably installed on the corresponding bracket.

[0012] Further optimization: an annular baffle is fixed on the outer edge of the outer wall of each of the arc-shaped guide plates, and the shape of the annular baffle is the same as the rolling track of the guide wheel.

[0013] Further optimization: each of the fan-shaped mounting frames includes a cross beam, a support block is fixed on the cross beam, the middle part of the arc guide plate is fixed on the support block, the two ends of the arc guide plate are respectively fixed to the two ends of the cross beam, a long supporting oblique beam is fixed to one end of the cross beam, and a short supporting oblique beam is fixed between the other end of the cross beam and the long supporting oblique beam.

[0014] Further optimization: upper mounting seats are fixed at both ends of the arc guide plate, a first lower mounting seat is fixed on the long supporting oblique beam, both ends of the active conical shaft are rotatably mounted on the first lower mounting seat and the corresponding upper mounting seat, a second lower mounting seat is commonly fixed on the short supporting oblique beam and the long supporting oblique beam, and both ends of the driven conical shaft are rotatably mounted on the second lower mounting seat and the corresponding upper mounting seat.

[0015] The utility model adopts the above technical solution and has the following beneficial effects:

[0016] The technical solution adopted by the utility model is ingenious in conception and reasonable in structure. The fan-shaped steering conveying device is arranged between the conveying end of the straight conveyor belt and the stacking box, which plays the role of connecting the straight conveyor belt and the stacking box and driving the green onions to turn and fall, thereby solving the problem of green onions falling and being damaged due to excessive transmission gap.

[0017] The setting of the arc guide plate and guide wheel plays a role in orienting and guiding the rotation of the fan-shaped conveyor belt, so that the fan-shaped conveyor belt always rotates according to the predetermined fan-shaped trajectory, ensuring the orderly transportation, turning and stacking of the onions.
