DETAILED DESCRIPTION

[0021] The structure of the utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model is a pepper harvester with a cleaning device 5 and a direct loading vehicle elevator 6, and its structure includes a vehicle body 1 and a walking system 2 arranged on the vehicle body 1, a picking device 3, a conveying device 4, a cleaning device 5, a direct loading vehicle elevator 6 and a hopper.

[0023] The traveling system 2 includes a chassis, an engine, wheels, a transmission mechanism, etc., and is used to drive and control the movement of the entire harvester.

[0024] The picking device 3 is located at the front end of the vehicle body 1, the conveying device 4 is located behind the picking device 3, the cleaning device 5 is located at the rear of the vehicle body 1 and at the rear end of the conveying device 4, and the direct loading vehicle elevator 6 is located at one side of the vehicle body 1 and connected to the cleaning device 5. The picking device 3 is used to pick peppers, and the picked peppers are transported backward and upward to the cleaning device 5 through the conveying device 4. The peppers move to one side along the cleaning device 5, and at the same time, impurities such as broken leaves and branches in the material are filtered out. The cleaned peppers are transported upward along the opened direct loading vehicle elevator 6 to the hopper of the transport vehicle that follows the harvester.

[0025] The picking device 3 includes a cutting platform frame 3-1, which is connected to the frame. A picking roller 3-2 is arranged at the front end of the cutting platform frame 3-1, and picking teeth are evenly distributed on the picking roller 3-2. The picking teeth are elastic rod-shaped structures with a certain length, and the ends of the picking teeth have a certain curvature. A ground wheel 3-3 is arranged at the lower end of the cutting platform frame 3-1, and the height of the cutting platform frame 3-1 can be adjusted by the ground wheel 3-3.

[0026] During the picking operation, the driving device drives the picking roller 3 - 2 to rotate, picks the peppers from the plants, and transports them to the conveying device 4 .

[0027] The conveying device 4 includes a primary elevator 4-1 and a secondary elevator 4-1 connected end to end. Both the primary elevator 4-1 and the secondary elevator 4-1 are inclined upward and backward, and the tail end of the primary elevator 4-1 is overlapped on the front end of the secondary elevator 4-1. The pepper is transported upward and backward through the primary elevator 4-1, and then falls on the secondary elevator 4-1, and is further transported to the cleaning device 5 by the secondary elevator 4-1. The primary elevator 4-1 and the secondary elevator 4-1 both include active rollers, driven rollers and conveying belts. Transverse bars are evenly distributed on the surface of the conveying belt. The driving device drives the active roller to rotate and drives the conveying belt to move. The pepper moves with the conveying belt in the area between two adjacent bars.

[0028] A re-picking device 8 may be provided at the end of the primary elevator 4-1, the front end of the secondary elevator 4-1 or the middle of the secondary elevator 4-1. In this embodiment, the re-picking device 8 is provided in the middle of the secondary elevator 4-1. The re-picking device 8 includes a re-picking roller, on which re-picking teeth are evenly distributed. The re-picking teeth are elastic rod-shaped structures with a certain length. The rotation direction of the re-picking teeth is opposite to the moving direction of the secondary elevator 4-1. When the secondary elevator 4-1 drives the peppers to pass through the re-picking device 8, the re-picking teeth separate the unseparated branches, fruits and leaves.

[0029] like Figure 4 , Figure 5 as well as Figure 6 As shown, the cleaning device 5 includes a cleaning frame 5-1, which is a part of the vehicle body 1. A plurality of cleaning rollers 5-2 are arranged side by side on the cleaning frame 5-1. The axial direction of the cleaning roller 5-2 is a horizontal front-to-back direction. A plurality of thumbwheels 5-3 are arranged on the cleaning roller 5-2. The thumbwheels 5-3 on two adjacent cleaning rollers 5-2 are staggered with each other, that is, the thumbwheel 5-3 on one cleaning roller 5-2 extends into the gap between two adjacent thumbwheels 5-3 on the other cleaning roller 5-2.

[0030] Among them, the thumbwheel 5-3 is a star-shaped structure.

[0031] The cleaning roller 5-2 is driven to rotate by the driving device, and the star-shaped dial wheel 5-3 scatters the peppers to be cleaned and transports them to one side during the rotation. The larger peppers will move along the dialing direction to the direct loading vehicle elevator 6, while the smaller impurities such as broken branches and leaves will fall from the gap between the dial wheels 5-3, thereby realizing the cleaning of the peppers.

[0032] A guide plate 5 - 4 is provided at the front end of the cleaning device 5 and at the side opposite to the direct loading vehicle elevator 6 , and the area where the materials are located is limited by the guide plate 5 - 4 .

[0033] The direct loading vehicle elevator 6 includes an elevator frame 6-1 arranged at the output end of the cleaning device 5. The elevator frame 6-1 is connected to the vehicle body 1 through a posture adjustment mechanism. The posture adjustment mechanism is used to adjust the posture of the elevator frame 6-1 so that it is in a vertical non-working state or a working state tilted upward to one side. A lifting and conveying belt mechanism 6-2 is arranged on the elevator frame 6-1, and baffle plates 6-3 are arranged on both sides of the elevator frame 6-1. The lifting and conveying belt mechanism 6-2 includes an active roller, a driven roller and a conveyor belt. The active roller is driven by a driving device to drive the conveyor belt to move. Baffle bars are evenly arranged on the surface of the conveyor belt. The baffle plates 6-3 are located on both sides of the conveyor belt. When the pepper is driven by the conveyor belt to move obliquely upward, the baffle plates 6-3 on both sides can prevent the material from being scattered.

[0034] In the working state, the peppers outputted by the cleaning device 5 are moved upward to one side of the vehicle body 1 through the lifting and conveying belt mechanism 6-2, and when they move to the end of the lifting and conveying belt mechanism 6-2, they fall into the hopper of the accompanying transport vehicle. In the non-working state, the direct loading vehicle elevator 6 is vertically attached to one side of the vehicle body 1.

[0035] Among them, the posture adjustment mechanism includes a posture adjustment frame 6-4 hinged on the lifting frame 6-1, the posture adjustment frame 6-4 is generally located in the lower middle part of the lifting frame 6-1, the hinge point between the posture adjustment frame 6-4 and the lifting frame 6-1 is located in the middle part of the lifting frame 6-1, and the first connecting rod 6-5 and the second connecting rod 6-6 are hinged on the posture adjustment frame 6-4. The first connecting rod 6-5 is located on the lower side of the hinge point between the posture adjustment frame 6-4 and the lifting frame 6-1, and the second connecting rod 6-6 is located on the upper side of the hinge point between the posture adjustment frame 6-4 and the lifting frame 6-1. The first connecting rod 6-5 and the second connecting rod 6-6 are parallel to each other and are respectively hinged on the vehicle body 1, thereby forming a parallelogram structure. A first telescopic cylinder 6-7 is hinged below the first connecting rod 6-5 and is hinged to the vehicle body 1. A second telescopic cylinder 6-8 is hinged at the upper end of the posture adjustment frame 6-4 and is hinged to the lifting frame 6-1.

[0036] When the direct loading vehicle elevator 6 needs to be in a non-working state, the first telescopic cylinder 6-7 contracts, so that the first connecting rod 6-5 drives the posture adjustment frame 6-4 to swing downward, and at the same time, the second telescopic cylinder 6-8 contracts, so that the lifting frame 6-1 swings to a vertical state. When the direct loading vehicle elevator 6 needs to be in a working state, the first telescopic cylinder 6-7 extends, so that the first connecting rod 6-5 drives the posture adjustment frame 6-4 to swing upward, and the direct loading vehicle elevator 6 is lifted upward. At the same time, the second telescopic cylinder 6-8 extends, driving the lifting frame 6-1 to rotate around the hinge point, so that the upper part of the direct loading vehicle elevator 6 tilts outward.

[0037] The utility model further comprises a spare hopper 7, which is arranged at the rear end of the vehicle body 1 and behind the cleaning device 5. When the hopper of the follower transport vehicle is full and is not replaced in time, the lifting and conveying belt mechanism 6-2 of the direct loading vehicle elevator 6 is temporarily closed, and the harvested peppers are temporarily stored in the cleaning device 5, and the excess peppers fall into the spare hopper 7 backwards, which will not affect the continuous and normal operation of the harvester. When a new transport vehicle arrives, the lifting and conveying belt mechanism 6-2 of the direct loading vehicle elevator 6 is restarted to transport the peppers in the cleaning device 5 to the hopper of the transport vehicle. The peppers stored in the spare hopper 7 can be finally dumped into the hopper of the transport vehicle at one time.

[0038] The utility model is suitable for large-scale pepper harvesting. During the harvesting process, there is no need to transport the peppers many times. The harvested peppers can be directly transported to a moving transport vehicle after being re-picked and cleaned, thereby improving the pepper harvesting efficiency and reducing the impurity content in the harvested peppers.
