Description

Technical Field

[0001] The utility model mainly applies to the technical field related to agricultural machinery, and specifically is a cleaning structure for a pepper harvester. Background Art

[0002] The automatic pepper harvesting and cleaning machine is mainly used for harvesting peppers and cleaning them for use. The related structures in the prior art (such as the publication number CN220087976U previously applied by our company, named a pepper harvesting and cleaning machine) mainly include a header, a cockpit, a silo, a conveying mechanism, a rough picking and cleaning mechanism, a fine picking and cleaning mechanism, and a rotating lifting and feeding mechanism. Its main working principle is to harvest peppers through the header, and the peppers with branches and leaves and branches first enter the rough picking and cleaning mechanism (i.e., the star wheel) for rough picking. During the rough picking process, some peppers can be separated from the branches and leaves and branches, and then enter the fine picking and cleaning structure to further clean the peppers. Finally, the cleaned peppers are lifted to the feeding and conveying mechanism by the lifting and feeding mechanism, and then sent to the silo.

[0003] In actual use, in order to ensure the cleaning effect, the peppers need to go through coarse picking, fine picking and other mechanisms to separate the branches and leaves from the peppers. The process is cumbersome and the corresponding mechanism design is complex, which makes the failure rate of using on-site harvesters high. In addition, the harvesters of the above-mentioned prior art can only realize automated operations at the harvesting site, and cannot clean the peppers that have been pulled out with pepper vines, thus restricting the use scenarios of the pepper harvesters. Utility Model Content

[0004] In order to solve the deficiencies of current technology, the utility model combines the existing technology and, based on practical application, provides a pepper harvester cleaning structure, which has the advantages of simpler structure, low equipment failure rate, and easy maintenance while ensuring the pepper cleaning efficiency and cleaning effect.

[0005] The technical solution of the utility model is as follows:

[0006] A cleaning structure for a pepper harvester comprises a feeding conveyor belt, a plurality of rows of small star wheel groups are sequentially arranged behind the feeding conveyor belt, gaps are provided between the small star wheel groups for peppers to pass through, a plurality of cleaning mechanisms are sequentially arranged above the small star wheel groups at intervals, the cleaning mechanism comprises a cleaning upper cover body and a cleaning and stripping roller assembly arranged inside the lower part of the cleaning upper cover body, a plurality of rows of fixed stripping teeth are arranged in the upper cover body, the cleaning and stripping roller assembly comprises a transmission shaft, the transmission shaft is connected to a power drive member, and a plurality of rows of movable stripping teeth are evenly arranged circumferentially on the transmission shaft.

[0007] Furthermore, the upper cover body is in an arc-shaped structure as a whole, and the fixed teeth are arranged in two rows on the upper cover body, and each row includes a plurality of fixed teeth.

[0008] Furthermore, the cleaning and stripping roller assembly also includes a support plate and a connecting plate. The multiple support plates are spaced in sequence and coaxially arranged with the transmission shaft. The outer rings of the support plates are connected through the connecting plates. The multiple connecting plates are evenly arranged in a circle. The movable stripping teeth are fixedly installed on the connecting plates, and multiple movable stripping teeth are installed on each connecting plate.

[0009] Furthermore, the movable stripping teeth on adjacent connecting plates are arranged alternately along the circumferential direction.

[0010] Furthermore, six connecting plates are provided so that six rows of movable teeth are evenly arranged in the circumferential direction of the transmission shaft.

[0011] Furthermore, the movable stripping teeth and the fixed stripping teeth are both cylindrical structures. The movable stripping teeth are fixed to the connecting plate by nuts, and the fixed stripping teeth are fixed to the upper cover body by nuts.

[0012] Furthermore, the cleaning mechanism is provided in three groups.

[0013] Furthermore, a group of large star wheel groups are arranged above the front of the small star wheel group, and the large star wheel group is located behind the feed conveyor belt.

[0014] Furthermore, a material receiving hopper is arranged behind the small star wheel assembly.

[0015] Furthermore, baffle plates are provided on both sides of the small star wheel assembly.

[0016] Beneficial effects of the utility model:

[0017] 1. The utility model does not need to set up a traditional auxiliary picking structure, but separates the pepper vines, branches and leaves from the peppers through three sets of cleaning mechanisms above the star wheel. The separated peppers fall onto the conveyor belt below, while the pepper vines, branches and leaves are discharged through the receiving hopper at the tail of the star wheel. Compared with the traditional structure, the cleaning structure ensures the efficiency and effect of pepper cleaning, making the equipment structure simpler and more compact, which not only reduces the cost of the equipment, but also facilitates the maintenance of the equipment, and also reduces the failure rate of the equipment at the use site.

[0018] 2. In the utility model, three groups of cleaning mechanisms are set up, which can not only clean the peppers with branches and leaves after harvesting by the harvesting table, but also clean the peppers with pepper vines. The peppers with pepper vines pulled out manually or by machine can be directly fed into the equipment through the feeding conveyor belt, thereby realizing the separation of peppers and branches and vines.

[0019] 3. In the utility model, the peppers are cleaned by the cooperation of fixed stripping teeth and movable stripping teeth. The structure is reasonable in design and has good stability. The peppers are well separated from branches and leaves and pepper vines. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0029] The present embodiment provides a pepper harvester cleaning structure, which is mainly used for cleaning peppers with branches or vines and for selecting the peppers separately.

[0030] refer to Figure 1 As shown, the front part of the harvester is a cutting table, and the rear part of the cutting table is a feed conveyor belt 1. The peppers with branches and leaves harvested by the cutting table enter the feed conveyor belt 1. The peppers with branches and leaves or pepper vines pulled out manually can also be manually or automatically fed into the feed conveyor belt 1.

[0031] A plurality of rows of small star wheel groups 3 are sequentially arranged behind the feed conveyor belt 1, and there are gaps between the small star wheel groups 3 for peppers to pass through. In this embodiment, the small star wheel groups 3 can realize the preliminary cleaning of peppers, that is, peppers with branches and leaves enter the small star wheel groups 3 from the feed conveyor belt 1, and when the small star wheel groups 3 are rotated, the fallen peppers fall through the gaps between the star wheels to the pepper conveyor belt below, and at the same time, through the action of the small star wheel groups 3, some branches and leaves can be separated from the peppers, so that the peppers are cleaned out.

[0032] Three groups of cleaning mechanisms 2 are arranged in sequence above the small star wheel group 3. The three groups of cleaning mechanisms 2 have the same structure and are used to clean the peppers with branches and leaves transported by the small star wheel group 3. In this embodiment, the cleaning mechanism 2 can achieve the separation of large branches and leaves, especially pepper vines and peppers. Among them, the cleaning mechanism 2 mainly includes a cleaning upper cover 7 and a cleaning roller assembly 8 arranged inside the lower part of the cleaning upper cover 7.

[0033] refer to Figure 4 , Figure 5 as well as Figure 6 The upper cover 7 is a semicircular cover structure as a whole, which is fixed on the main frame. Two rows of fixed stripping teeth 9 are fixed on the inner surface of the upper cover 7, and each row includes a plurality of fixed stripping teeth 9. The cleaning stripping roller assembly 8 mainly includes a transmission shaft 10, which can rotate after being connected to the power drive member, and multiple rows of movable stripping teeth 13 are evenly arranged around the transmission shaft 10. When the pepper with branches and leaves is transported backward with the small star wheel assembly 3, the branches and leaves pass through the cleaning stripping roller assembly 8, and the movable stripping teeth 13 rotate to drive the branches and leaves to move. When the branches and leaves pass through the fixed stripping teeth 9 in the upper cover 7 under the action of the movable stripping teeth 13, the pepper and the branches and leaves are separated by the relative movement between the movable stripping teeth 13 and the fixed stripping teeth 9, and the separated pepper falls to the conveyor belt below, and most of the branches and leaves continue to be transported backward with the small star wheel assembly 3, and are gradually cleaned by the subsequent two cleaning mechanisms 2 in turn, until they are finally completely cleaned. At the same time, a blower can be arranged at the rear of the pepper conveyor belt to blow out the branches and leaves carried by the pepper dropped from the small star wheel group 3.

[0034] In this embodiment, the cleaning and stripping roller assembly 8 needs to carry pepper vines and branches and leaves when rotating, and needs to cooperate with the fixed stripping teeth 9 to produce a certain tearing force, so the cleaning and stripping roller assembly 8 is subjected to a large force. For this reason, this embodiment has a special structural design for the cleaning and stripping roller assembly 8 to ensure its performance while making it have better stability. Figure 6The cleaning and stripping roller assembly 8 further includes three support plates 11 and six connecting plates 12. The three support plates 11 are spaced in sequence and are coaxially arranged with the transmission shaft 10. The outer rings of the support plates 11 are connected by six connecting plates 12. The six connecting plates 12 are evenly arranged along the circumferential direction to form six rows of movable stripping teeth 13. Each row includes a plurality of movable stripping teeth 13. The movable stripping teeth 13 are cylindrical in structure, have threads, and are fixed by nuts. Among the six connecting plates 12, the movable stripping teeth 13 between adjacent connecting plates 12 are staggered to improve the cleaning ability.

[0035] As a preferred solution of this embodiment, a group of large star wheel groups 4 are arranged above the front of the small star wheel group 3. The large star wheel group 4 is located behind the feed conveyor belt 1 and is used to move the peppers with branches and leaves into the subsequent cleaning mechanism 2. Baffle plates 6 are arranged on both sides of the small star wheel group 3 to ensure that the peppers will not fall from both sides.

[0036] In this embodiment, a receiving hopper 5 is provided behind the small star wheel group 3. The receiving hopper 5 can be turned over, and the pepper vines and branches and leaves after being cleaned enter the small star wheel group 3, and are accumulated on the receiving hopper 5. After reaching a certain weight, the receiving hopper 5 is tilted downward to make the pepper vines and branches and leaves fall to the ground.
