[0002] The research on pepper harvesting machinery in China has been carried out for a relatively short time. A pepper harvester can only be fixed to harvest a certain type of pepper. At present, some developed pepper harvesters basically do not have the functions of straw crushing and cleaning. As a result, a large amount of straw and pepper leaves are mixed in the mechanically harvested pepper products, and the harvested pepper products still need to be manually separated from the straw and pepper leaves, which is laborious and time-consuming. Summary of the Invention

[0003] The purpose of the present invention is to provide a combined device for pepper picking, pepper branch separation and cleaning in view of the above-mentioned deficiencies of the prior art. Different types of peppers can be harvested by adjusting relevant parameters, and the device integrates pepper picking, straw treatment and pepper cleaning, realizing the automation and integration of pepper picking.

[0004] The technical solution of the present invention is: a combined device for pepper picking, pepper branch separation and cleaning, which is characterized by comprising: a support and collection module, a pepper picking module, a pepper branch separation module, and a cleaning module. The support and collection module is arranged on the ground, the pepper picking module is installed above the support and collection module, the pepper branch separation module is installed below the pepper picking module, and the cleaning module is installed below the pepper branch separation module.

[0005] The support and collection module includes a frame structure, a first funnel, a second funnel, and a pepper collection box; the first funnel, the second funnel, and the pepper collection box are arranged in sequence at the top, middle, and bottom of the frame structure.

[0006] The picking module is arranged between the first funnel and the second funnel, and includes a pair of parallel upper comb-tooth drums and a pair of parallel lower comb-tooth drums; the pair of upper comb-tooth drums are driven to run towards each other, and the pair of lower comb-tooth drums are driven to run towards each other. The material is put into the first funnel, and after passing through the two pairs of comb-tooth drums running towards each other, the peppers are separated from the straw and sent into the second funnel together.

[0007] The pepper branch separation module is arranged below the second funnel, and includes a screw conveyor, a screw conveyor motor, and a sorting sieve; the screw conveyor motor is drivingly connected to the screw conveyor, and the sorting sieve is located below the screw conveyor; the straw is conveyed by the screw conveyor to a straw crusher, and the peppers fall through the sorting sieve.

[0008] The cleaning module is arranged below the sorting sieve and above the pepper collection box, and includes a blower and an air duct; the peppers fall through the air duct and then enter the pepper collection box; the blower is installed on one side of the air duct for blowing away the sundries in the peppers.

[0009] In the above solution, the functions of pepper picking, pepper branch separation, and cleaning are integrated into one, which improves work efficiency and reduces the floor area of the equipment. By adjusting the spacing of the upper comb tooth drum and the spacing of the lower comb tooth drum, it can be applicable to peppers of different sizes and harvest different types of peppers. When the device is running, the straw with peppers is put into hopper one. Through the opposite movement of the upper and lower comb tooth drums, the peppers and the straw are initially separated and enter hopper two. The material enters the auger. Through the transportation of the auger and the screening of the sorting sieve, the peppers and the straw are further separated. The straw is transported to the crusher for processing. The peppers enter the air duct, and the sundries and pepper leaves are blown away by the airflow generated by the blower and finally enter the pepper collection box.

[0010] Further, several groups of comb teeth are respectively arranged on the outer circumferential surface of the upper comb tooth drum and the outer circumferential surface of the lower comb tooth drum. Each group of comb teeth is composed of multiple strip-shaped teeth evenly distributed along the circumferential direction, and several groups of comb teeth are evenly distributed along the axial direction of the corresponding comb tooth drum. For two comb tooth drums in the same horizontal group, in the axial direction, the comb teeth are staggered; for two comb tooth drums on the same side up and down, in the axial direction, the comb teeth are staggered.

[0011] In the above solution, this design of the comb teeth can better realize the separation of peppers and straw. After the material enters hopper one, it first contacts the upper comb tooth drum. The comb teeth of the upper comb tooth drum are inserted into the material, and the peppers are picked off the straw through the opposite movement. The picked peppers and part of the straw are sent to the lower comb tooth drum together, and the lower comb tooth drum continues to further separate the peppers and the straw through the opposite movement.

[0014] Further, each lead screw of the second linear module is respectively provided with two external threads with opposite helix directions, and the two external threads with opposite helix directions are respectively threadedly connected to two second sliders to drive a pair of upper comb-tooth rollers to move towards or away from each other; each lead screw of the third linear module is respectively provided with two external threads with opposite helix directions, and the two external threads with opposite helix directions are respectively threadedly connected to two third sliders to drive a pair of lower comb-tooth rollers to move towards or away from each other.

[0015] Further, the pepper branch separation module further includes a straw crusher, and the straw crusher is installed at the discharge end of the auger and can crush the separated straw.

[0016] Further, the blades of the auger are formed by arranging multiple spiral long strips at intervals to form a hollow spiral blade. The distance between adjacent spiral long strips is greater than the maximum width of the pepper, which just allows the pepper to fall from the auger blades to convey the straw and complete the further separation of the pepper and the straw.

[0017] Further, the sorting sieve is formed by arranging a number of long straight strips at intervals, and the distance between adjacent long straight strips is greater than the maximum width of the pepper to ensure that the pepper can pass through the sieve smoothly.

[0018] Further, the air duct is provided with an air outlet on the side opposite to the blower, and the bottom of the air duct is provided with a discharge port communicated with the pepper collection box.
