Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, and relates to a pepper harvesting device, in particular to a picking device which can be adjusted according to the height of pepper plants. Background Art

[0002] Pepper is an annual or limited perennial herb or shrub. Depending on the variety of pepper, the plant height of pepper is usually 400-800mm. Pepper is mainly eaten with its fruit, rich in vitamin C, and usually used as a condiment. It is one of China's important export agricultural products. It not only has rich nutritional value, but also is an important industrial and pharmaceutical raw material with good economic benefits. At present, pepper picking is still mainly done by manual harvesting, which has problems such as high labor intensity and low picking efficiency. Existing pepper harvesters are mostly large harvesters, which are only suitable for pepper harvesting operations in field planting, and cannot meet the requirements of pepper harvesting operations in small plots or greenhouse planting.

[0003] The utility model of Chinese patent application number CN2020214199454 discloses a small hand-held pepper harvester. The technical solution is mainly composed of a picking mechanism, a transmission and collection mechanism and a carrying part. The picking mechanism is used to separate the pepper from the stem; the transmission and collection mechanism is used to transmit and collect the pepper; and the carrying part is used to carry the picked pepper. When in use, the pepper plant enters the middle of the double screw rod through the forward guide plate, and the screw rod rotates outward from bottom to top to strangle the pepper. The fallen pepper slides into the conveyor belt with a scraper through the pepper guide plate, and finally the conveyor belt conveys it to the collection box to harvest the pepper. During use, the harvester needs to manually adjust the forward direction to complete the pepper harvesting operation, and the angle of the picking mechanism is a fixed value, which cannot be adjusted in real time according to the height of the pepper plant. The degree of automation is low and the applicability of the machine is poor. Therefore, in order to meet the picking needs of peppers of different plant heights and improve their applicability, it is necessary to make structural improvements to the existing pepper harvester. Utility Model Content

[0004] The utility model aims at the shortcomings of the current pepper harvester, such as the fixed picking angle, the inability to adjust in real time according to the height of the pepper plants, and the poor applicability of the machine. An adjustable pepper picking device is proposed. The various mechanisms of the device can be quickly installed and disassembled, and the picking angle and height of the actuator can be adjusted to meet the picking needs of peppers with different plant heights, thereby further improving its applicability.

[0005] The adjustable pepper picking device provided in this application adopts the following technical solution:

[0008] The actuator is composed of a mounting frame, a spring-toothed roller, a pressure roller, a reduction motor, and a conveyor belt. The spring-toothed roller is driven by the reduction motor. The entire actuator is connected to the travel mechanism and can rotate relative to the travel mechanism.

[0009] An angle adjustment mechanism has one end movably connected to the walking mechanism and the other end movably connected to the actuator.

[0010] By adopting the above technical scheme, the walking mechanism realizes the movement of the entire picking device, the actuator realizes the pressing down of the pepper plants, the picking and transportation of the peppers, and the angle adjustment mechanism realizes the adjustment of the rotation angle of the actuator relative to the walking mechanism, thereby meeting the picking needs of peppers with different plant heights.

[0011] Furthermore, a support rod is fixedly connected to the middle of the frame, a first hinge seat is connected to the top of the support rod, and a fixed hinge connecting rod is connected to the bottom.

[0012] By adopting the above technical solution, the support rod can connect and fix the frames on both sides to make the structure of the walking mechanism more stable, and on the other hand, the support rod facilitates the installation of the actuator and the angle adjustment structure.

[0013] Furthermore, the fixed hinged link is composed of a first screw rod, a first fastening nut, a second fastening nut, and a first fisheye joint, and the fixed hinged link is clamped and fixed to the support rod by the first fastening nut and the second fastening nut.

[0014] By adopting the technical solution, the fixed hinge rod and the support rod are fixedly connected, and the lifting and lowering fixed positions can be adjusted by tightening nuts at the upper and lower ends, thereby fine-tuning the height direction of the actuator.

[0015] Furthermore, a collection box is connected to the rear end of the frame.

[0016] By adopting the above technical solution, the setting of the collection box is conducive to the placement of peppers after picking, so as to meet the continuity of the picking operation.

[0017] Furthermore, a second hinged seat is provided at the top front end of the mounting frame, and a third hinged seat is connected to the rear end. The actuator is hingedly connected to the fixed hinged connecting rod through the third hinged seat, so that the actuator as a whole can rotate at a certain angle relative to the walking mechanism.

[0018] By adopting the above technical solution, the third hinge seat realizes the rotation connection between the actuator and the support rod, and the second hinge seat realizes the movable connection among the actuator, the angle adjustment mechanism and the support rod.

[0019] Furthermore, a guide plate is connected to the front end of the actuator, and a pressure roller is arranged at a lower rear side of the guide plate to press down the peppers at a high position and smoothly send them into the spring-tooth roller for picking.

[0020] By adopting the above technical solution, the setting of the guide plate can effectively prevent the plants from tipping over to the sides after the pressing roller presses the plants down, and can form an effective limit to ensure the picking quality.

[0021] Furthermore, one end of the conveyor belt is arranged below the rear side of the spring-toothed drum, and the other end is arranged above the collecting box.

[0022] By adopting the above technical solution, the setting of the conveyor belt can continuously transport the peppers picked by the spring-toothed roller to the collection box, thereby ensuring the continuity of the picking operation and improving the picking efficiency.
