Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, and more specifically, the utility model relates to a leafy vegetable harvesting device. Background Technique

[0002] Leafy vegetables have become an important part of a healthy diet due to their rich content of vitamins, minerals, and dietary fiber. With the growth of the population and the improvement of living standards, the demand for leafy vegetables is increasing day by day, which has promoted the rapid development of the leafy vegetable industry. However, the harvesting link in the leafy vegetable production process traditionally relies on a large amount of manual labor, which not only has a high labor intensity and low efficiency, but also faces challenges such as labor shortage and rising costs. Therefore, mechanized harvesting technology has become the key to improving the production efficiency of leafy vegetables and reducing production costs.

[0003] When the existing mechanical devices for leafy vegetable harvesting are in use, generally, the leafy vegetables are cut by a cuttable cutter head at the bottom and then driven to a conveyor belt by a rotating support assembly, and then the leafy vegetables are carried to the inside of a collection box through the conveyor belt. The problem here is that the collection box is relatively heavy when full, and it is laborious and time-consuming for the operator to remove it, which is not convenient. At the same time, the sizes of the collection boxes may be different. When the top of a larger collection box is at a higher position, due to the limited top position of the conveyor belt and the inability to adjust it, it will affect the placement of a larger volume collection box for collection. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a leafy vegetable harvesting device.

[0005] To achieve the above object, the utility model provides the following technical solution: A leafy vegetable harvesting device, including a chassis, walking wheels are installed on the outer side of the bottom of the chassis, and a leafy vegetable collection box is installed on the top of one end of the chassis. A push-pull handle is arranged on the outer wall of the top of the leafy vegetable collection box, and a lifting handle is arranged on the outer wall of the bottom of the leafy vegetable collection box. A roller is movably installed on the top of the chassis near the outer side of the leafy vegetable collection box. A leafy vegetable conveying mechanism is installed on one side of the leafy vegetable collection box above the chassis. A rotating support assembly is installed on one side of the leafy vegetable conveying mechanism. A cutter head is installed on the bottom of the chassis near the lower side of the rotating support assembly, and a reciprocating driver for driving the cutter head to reciprocate is installed on the bottom of the chassis;

[0006] The leafy vegetable conveying mechanism includes a lower driving roller and an upper driving roller. A leafy vegetable transmission belt is drivingly connected between the outsides of the lower driving roller and the upper driving roller. The lower driving roller is arranged on the lower side of the upper driving roller. Both ends of the lower driving roller are movably connected with a first fixed seat. At both sides of the upper driving roller along the vertical direction, the top of the chassis is fixedly connected with limiting side plates. At the top of the two limiting side plates, there are arc-shaped notch parts with the lower driving roller as the center of the arc. At the position of the end of the central shaft of the upper driving roller on the outer wall of the limiting side plate, a fixed plate is fixedly connected. On the outer wall of the fixed plate, a first motor for driving the upper driving roller to rotate is installed. At equal intervals on both sides of the arc-shaped notch part on the outer wall of the limiting side plate, there are a number of connecting screw holes.

[0007] As a further improvement of the technical solution of the present invention, an arc-shaped groove for roller installation is provided on the top of the chassis. A fixed shaft is horizontally penetrated through the middle of the roller, and both ends of the fixed shaft are fixedly connected with the inner wall of the top of the chassis.

[0008] As a further improvement of the technical solution of the present invention, a power distribution control box is installed on one side of the top of the chassis close to the limiting side plate. The bottom of the limiting side plate is fixedly connected with the top of the chassis through bolts.

[0009] As a further improvement of the technical solution of the present invention, a number of limiting protrusions are equidistantly arranged on the outer surface of the leafy vegetable transmission belt.

[0010] As a further improvement of the technical solution of the present invention, bolts are connected to the positions on the outer wall of the fixed plate corresponding to the connecting screw holes, and the first motor is fixedly connected to the outer wall of the fixed plate through screws.

[0011] As a further improvement of the technical solution of the present invention, the rotating support assembly includes two rotating wheels. A rotating shaft is connected between the middles of the two rotating wheels, and a number of rotating rods are annularly and equidistantly connected between the edges of the two rotating wheels. At both sides of the rotating shaft on the top of the chassis, second fixed seats are fixedly connected. On the outer wall of the top of the second fixed seat, a second motor for driving the rotating shaft to rotate is installed.

[0012] As a further improvement of the technical solution of the present invention, the second motor is fixedly connected to the outer wall of the second fixed seat through screws, and a bearing seat is installed at the position corresponding to the end of the rotating shaft on the inner wall of the second fixed seat.

[0013] The beneficial effects of the present invention:

[0014] 1. By setting a push-pull handle, a lifting handle and a roller on the leafy vegetable collection box, the push-pull handle is used for the operator to place and remove the leafy vegetable collection box from the chassis. The lifting handle set at the bottom is used to lift upward after the leafy vegetable collection box is filled with leafy vegetables, and then the leafy vegetable collection box is dragged above the roller and released. At this time, the roller supports the leafy vegetable collection box. When pulling the leafy vegetable collection box outward by pulling the push-pull handle, the rotation of the roller will be more labor-saving and the removal efficiency will be higher;

[0015] 2. A structure for adjusting the angle of the leafy vegetable transmission mechanism is provided. During use, according to the height of different leafy vegetable collection boxes, first remove the bolts on the fixed plate, and control the angle of the leafy vegetable transmission mechanism with the lower transmission roller as the arc center. At this time, the upper transmission roller moves inside the arc-shaped notch, and the position of the fixed plate changes accordingly. When adjusted to the required position, the processing fixed plate is fixed to the connecting screw hole at the corresponding position through bolts to complete the fixation. At this time, the leafy vegetables transmitted by the leafy vegetable transmission belt will be adjusted correspondingly according to the different heights of the leafy vegetable collection boxes, so as to adapt to the collection requirements of the leafy vegetable collection boxes.
