Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more specifically to a cleaning wheel and pepper cleaning and separation device and a pepper harvester. Background Art

[0002] Peppers are rich in nutritional value. They are not only one of the indispensable vegetables on the Chinese table, but also one of the important economic crops in many provinces of my country. The main ways of harvesting peppers include mechanical harvesting and manual picking. The cost of mechanically harvested peppers is much lower than that of manual picking. With the advancement of my country's agricultural mechanization process, most areas have begun to promote the use of mechanized harvesting of peppers, and many different forms of pepper harvesters have appeared on the market.

[0003] Although the application of pepper harvesters has gradually become popular, the research on the cleaning and separation devices of their core components is still relatively scarce. The cleaning wheel, as its main cleaning structure, provides a strong pepper separation and screening ability. However, during the cleaning process, wet soil and small branches and leaves on the surface of the peppers will remain on it, which is difficult to completely remove. This not only affects the subsequent cleaning effect, but may also contaminate the inside of the cleaning and separation machine, further reducing the sorting quality of the peppers. Secondly, the pepper cleaning and separation device has the problems of high impurity rate and low fruit separation rate during the cleaning process, and is prone to clogging when processing a large amount of pepper mixtures, resulting in a decrease in the quality of the peppers.

[0004] To this end, the present application proposes a cleaning wheel and a pepper cleaning and separation device and a pepper harvester to solve the above problems. Summary of the invention

[0010] In a new embodiment, the top of the airflow ring tube is in an oblique shape, and a plurality of airflow holes are evenly spaced on the top of the airflow ring tube, and the direction of the airflow holes is consistent with the claw-shaped bending direction of the cleaning wheel claw.

[0011] A pepper cleaning and separation device comprises the cleaning wheel and an auxiliary frame installed at the rear of the assembly table, and also comprises: an inclined roller plate, which is installed at the front middle part of the auxiliary frame; a height limiting component, which is arranged at the top of the inclined roller plate, and is used to limit the height and sliding of the falling peppers; a leakage oblique box, which is installed at the rear of the inclined roller plate; a sliding plate, which is installed at the rear of the leakage oblique box; an air blowing plate, which is installed at the rear of the inclined roller plate, and the wind direction of the air blowing plate is consistent with the oblique angle of the leakage oblique box; an air supply component, which is installed at the front lower side of the auxiliary frame, and is used to provide wind supply for the air blowing plate; a transverse plate is installed on the upper rear side of the auxiliary frame, a semi-cylindrical air bag is installed at the bottom end of the transverse plate, and an oblique guide plate is also installed at the front end of the transverse plate, and a downwind outlet is also installed in the middle of the oblique guide plate, and the downwind outlet is connected to the air supply component.

[0012] In a new embodiment, the height limiting component includes: a horizontal steel frame, which is installed on the top of the auxiliary frame; a plurality of hydraulic rods, all of which are installed in the middle of the horizontal steel frame; an outer inclined cover shell, which is arranged at the bottom of the horizontal steel frame, and the top of the outer inclined cover shell is fixedly connected to the telescopic end of the hydraulic rod; a flexible roller, which is rotatably installed in the middle of the outer inclined cover shell, and the distance between the flexible roller and the inclined roller plate can be adjusted by lifting and lowering the hydraulic rod.

[0013] In a new embodiment, the air supply assembly includes: a chassis plate, which is installed on the front lower side of the auxiliary frame; two air pumps are provided, which are respectively installed on the left and right sides of the top end of the chassis plate; two groups of branch pipes are provided, which are respectively installed on the left and right sides of the auxiliary frame, and the air inlet end of the branch pipe is connected to the exhaust port of the corresponding air pump, and there are two exhaust ends of the branch pipe, one of which is connected to the wind blowing block, and the other is connected to the downwind exhaust port; airflow regulating valves are respectively installed on the two exhaust ends of the branch pipe.

[0018] By utilizing the inclined rolling plate and the height limiting component to coordinately receive and cause the peppers to roll down, it can limit the height and prevent damage while ensuring that the peppers enter the subsequent separation process evenly and orderly. The wind blowing plate and the air supply component are used to make the peppers fly away to the horizontal plate position, and are buffered and received by the semi-cylindrical airbag at the bottom of the horizontal plate, and finally fall into the sliding plate for subsequent processes, thereby achieving efficient and safe processing of the peppers.

[0019] When the peppers fly away and reach the middle position between the inclined guide plate and the leaking inclined box, the downward wind force generated by the downwind outlet on the inclined guide plate helps to remove impurities and dust on the surface of the peppers, and can blow down the peppers that are flat or do not meet the quality standards within a certain quality range and be caught by the leaking inclined box, while the peppers that meet the quality standards continue to fly away and reach the sliding plate, so that the dry flat peppers can be removed and the pepper sorting quality can be improved.

[0020] By setting up the air supply component, the wind force demand of the wind-blown plate is met and additional wind force support is provided for the downwind outlet. By matching the branch pipe and the airflow regulating valve, the wind force of the wind-blown plate and the downwind outlet can be flexibly adjusted, thus realizing the wind force regulation effect on the wind-blown plate and the downwind outlet.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present application provides a cleaning wheel, a pepper cleaning and separation device and a pepper harvester, thereby solving the problem that although the existing cleaning wheel has a powerful separation and screening effect, it is difficult to remove the wet soil and branches and leaves contaminated by itself, and at the same time, in the process of transporting and sorting a large number of peppers, the cleaning and separation device has a high impurity rate and a low fruit separation rate, which affects the quality of the peppers. When in use, the cleaning wheel itself is cleaned, and the impurity removal rate and dry flat pepper separation rate of the cleaning and separation device are improved.

[0040] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows. Example 1

[0041] See also Figure 1-Figure 11A cleaning wheel includes an assembly platform 1, and also includes: a plurality of inner hollow rollers 2, which are equidistantly installed on the top of the assembly platform 1; a plurality of inner cavity disks 3, which are equidistantly installed inside the inner hollow roller 2, and a centrifugal disk 4 is also installed in the middle of the inner cavity disk 3; a plurality of column sleeves 5, which are equidistantly installed in an annular shape on the outside of the inner cavity disk 3, and the outer ends of the column sleeves 5 all penetrate the inner wall of the inner hollow roller 2 and extend to the outside; an airflow ring tube 6, which is installed on the inner wall of the column sleeve 5, and the bottom of the airflow ring tube 6 is connected to the outer side of the inner cavity disk 3; a cleaning wheel claw 8, which is arranged in the middle of the column sleeve 5 and the airflow ring tube 6, and the cleaning wheel claw 8 is arranged in the middle of the column sleeve 5 and the airflow ring tube 6. The inner ends of the wheel claws 8 are fixedly mounted on the outer side of the inner cavity disk 3; a round-head arc cavity 9 is opened inside the inner cavity disk 3, and a gravity hemisphere 10 slides inside the round-head arc cavity 9, and the plane end of the gravity hemisphere 10 is connected to one end of an extrusion airbag 11, and the other end of the extrusion airbag 11 is fixed to the bottom wall of the plane end of the round-head arc cavity 9, and a return spring 12 is also sleeved on the outer side of the extrusion airbag 11; the exhaust port of the extrusion airbag 11 is connected to one end of an embedded tube 13, and the embedded tube 13 is installed inside the centrifugal disk 4, and the other end of the embedded tube 13 is connected to the inner cavity disk 3, and the inner cavity disk 3 is connected to the airflow ring tube 6.

[0042] In this example, see Figure 1-Figure 11 As shown, by improving the cleaning wheel, the cleaning wheel is composed of an inner hollow roller 2, an inner cavity disk 3, a centrifugal disk 4, a column sleeve 5, an airflow ring tube 6 and a cleaning wheel claw 8 to form the entire cleaning wheel structure. When the inner hollow roller 2 rotates forward, it is matched with the conveyor belt installed at the lower part to remove the stems and leaves and screen the peppers. When the inner hollow roller 2 is subsequently in a stagnant and non-operating state, the rotation direction is changed from forward rotation to backward rotation. The reverse rotation of the inner hollow roller 2 is utilized to make the inner cavity disk 3 and the centrifugal disk 4 in a centrifugal state. Each time the inner hollow roller 2 rotates one circle from back to front, the backward swinging action force generated will make the gravity hemisphere 10 in the round head arc cavity 9 move in a circular motion. The head arc cavity 9 slides under the restriction and guidance and the weight of the gravity hemisphere 10, thereby squeezing and compressing the extrusion airbag 11, and generating intermittent airflow by using the extrusion airbag 11. This intermittent airflow passes through the airflow path of the extrusion airbag 11, the embedded tube 13, the inner cavity disk 3, and the airflow ring tube 6, and is finally ejected from the airflow hole 7 to remove the solid impurities on the cleaning wheel claw 8. The coordinated use of the extrusion airbag 11 and the return spring 12 ensures the stability and controllability of the airflow output. The return spring 12 can quickly restore its original shape after the extrusion airbag 11 is released, so as to prepare for the next airflow output.

[0043] For further information, see Fig. 9 One end of the return spring 12 is connected to the plane end of the gravity hemisphere 10, and the other end is connected to the bottom wall of the plane end of the round head arc cavity 9.

[0044] When the gravity hemisphere 10 slides in the round head arc cavity 9 and compresses the extrusion airbag 11, the return spring 12 will be compressed and store elastic potential energy. When the gravity hemisphere 10 leaves the extrusion position due to the reduction of centrifugal force or the change of direction, the return spring 12 will release the stored elastic potential energy to push the gravity hemisphere 10 and the extrusion airbag 11 back to the initial position, thereby achieving precise control of the airflow output. The extrusion airbag 11 will also return air through the embedded tube 13 and the one-way air intake pipe during the resetting of the return spring 12. Through the compression and release process of the return spring 12, intermittent airflow output can be generated. This intermittent airflow helps to remove solid impurities on the wheel claw 8.

[0045] For further information, see Figure 7-Figure 8 One-way air inlet pipes are installed on the left and right sides of the centrifugal disk 4, and the one-way air inlet pipes are connected to the embedded tube 13. Grooves 14 are provided on the front and rear sides of the inner wall of the inner hollow roller 2. The length of the groove 14 is equal to the length of the inner hollow roller 2. By setting the one-way air inlet pipe, it is possible to ensure smooth air intake, and the squeezing airbag 11 can quickly replenish gas. The incoming gas can only enter the embedded tube 13 through the one-way air inlet pipe, and then enter the squeezing airbag 11, avoiding the confusion and backflow of the airflow, and the groove 14 opened on the inner hollow roller 2 is convenient for the air flow inside and outside the inner hollow roller 2.

[0046] Under the action of the above centrifugal force, the gravity hemisphere 10 slides and compresses the squeezing airbag 11. In this process, the gas inside the squeezing airbag 11 is compressed and pressure accumulates. When the pressure reaches a certain level, the setting of the one-way air intake pipe allows external air to enter the squeezing airbag 11 in a controlled manner, thereby achieving a further increase in the pressure inside the airbag without adding additional power. This setting is not intended to make the reaction force generated by the gas pressure always greater than the sum of resistances such as centrifugal force and friction, but by controlling the intake timing and intake volume of the one-way air intake pipe (the one-way air intake pipe is a controllable intelligent air intake valve, which is more accurate in controlling the intake timing and intake volume of the one-way air intake), so that the squeezing airbag 11 can release part of the gas at the end of each compression cycle, and The elastic potential energy of the spring 12 is used to restore the extrusion airbag 11 to its initial state to prepare for the next compression. Secondly, from the perspective of the rotation and cleaning of the cleaning wheel (inner hollow roller 2 and cleaning wheel claw 8), the cleaning wheel rotation and cleaning process is not a continuous rotation, but stops after 3-5 rotations. When the cleaning wheel rotates for 3-5 rotations, the internal gravity hemisphere 10 and the extrusion airbag 11 are used to form wind supply, and the cleaning wheel rotates to clean the outside of the cleaning wheel (mainly the cleaning wheel claw 8 position). When the cleaning wheel is stopped, the cleaning wheel will not be affected by the centrifugal force of the rotation. Therefore, the spring 12 drives the extrusion airbag 11 to reset due to the elastic potential energy, waiting for the output gas in the next cleaning wheel rotation cleaning. This is repeated for many times to complete the air supply and cleaning of the cleaning wheel.

[0047] For further information, see Fig.10 and Fig.11 The top of the airflow ring tube 6 is in an oblique shape, and a plurality of airflow holes 7 are evenly spaced on the top of the airflow ring tube 6 , and the direction of the airflow holes 7 is consistent with the claw-shaped bending direction of the cleaning wheel claw 8 .

[0048] The airflow holes 7 equidistantly distributed on the top of the airflow ring tube 6 can ensure the uniformity of the airflow around the cleaning wheel claw 8. Each airflow hole 7 can stably supply airflow, effectively avoiding the problem of uneven local airflow intensity, thereby improving the consistency of the cleaning effect. The provision of multiple airflow holes 7 also enables the airflow to more comprehensively cover the outer wall of the cleaning wheel claw 8, promotes full contact between the outer wall of the cleaning wheel claw 8 and the airflow, and helps to more efficiently separate and remove solid impurities attached to the cleaning wheel claw 8, thereby realizing the self-cleaning ability of the cleaning wheel. Example 2

[0049] See also Figure 12-16 A pepper cleaning and separation device includes a cleaning wheel and an auxiliary frame 15 installed at the rear of an assembly table 1, and also includes: an inclined rolling plate 16, which is installed at the front middle of the auxiliary frame 15; a height limiting component 17, which is arranged on the top of the inclined rolling plate 16, and is used to limit the height and slide of the falling pepper; a leaking inclined box 18, which is installed at the rear of the inclined rolling plate 16; a sliding plate 19, which is installed at the rear of the leaking inclined box 18; a wind blowing plate 20, which is installed at the rear of the inclined rolling plate 16, and The wind direction of the wind blowing plate 20 is consistent with the oblique angle of the leak oblique box 18; the air supply component 21 is installed on the front lower side of the auxiliary frame 15, and is used to provide wind supply for the wind blowing plate 20; a transverse plate 22 is installed on the rear upper side of the auxiliary frame 15, and a semi-cylindrical air bag 23 is installed at the bottom end of the transverse plate 22, and an oblique guide plate 24 is also installed at the front end of the transverse plate 22, and a downwind outlet 25 is also installed in the middle of the oblique guide plate 24, and the downwind outlet 25 is communicated with the air supply component 21.

[0050] In this example, see Figure 12-16 As shown, the inclined rolling plate 16 and the height limiting component 17 work together to receive small and large quantities of peppers such as chili peppers and cause them to roll down. During the rolling process, the height limiting component 17 effectively limits the sliding height and speed of the peppers, preventing the peppers from being damaged due to excessive speed, while ensuring that the peppers can enter the subsequent separation process evenly and orderly. When the rolling peppers reach the position of the wind blowing plate 20 on the inclined rolling plate 16, the wind blowing plate 20 and the air supply component 21 are used in combination to enable the peppers to fly away with wind and fall to the horizontal plate 22. The semi-cylindrical air bag 23 at the bottom of the horizontal plate 22 plays a buffering and receiving role, and then the peppers fall to the sliding plate 19 and continue to roll down to enter the subsequent process.

[0051] Among them, when the peppers fly away to the middle position between the inclined guide plate 24 and the leak-mouth inclined box 18, the downward wind force generated by the downwind outlet 25 on the inclined guide plate 24 helps to remove impurities and dust on the surface of the peppers, and can blow down the peppers that are flat or do not meet the quality standards within a certain quality range. These blown-off peppers are received by a receiving device (not shown in the figure) installed at the bottom of the leak-mouth inclined box 18, while the peppers that meet the quality standards fly away to the sliding plate 19 and continue to be transported to the next link.

[0052] For further information, see Fig.12 and Fig.16 The height limiting component 17 includes: a horizontal steel frame 1701, which is installed on the top of the auxiliary frame 15; a plurality of hydraulic rods 1702 are provided, all of which are installed in the middle of the horizontal steel frame 1701; an outer inclined cover shell 1703 is provided at the bottom of the horizontal steel frame 1701, and the top of the outer inclined cover shell 1703 is fixedly connected to the telescopic end of the hydraulic rod 1702; a flexible roller 1704 is rotatably installed in the middle of the outer inclined cover shell 1703, and the distance between the flexible roller 1704 and the inclined roller plate 16 can be adjusted by lifting and lowering the hydraulic rod 1702.

[0053] By adjusting the lifting and lowering of the hydraulic rod 1702, the distance between the flexible roller 1704 and the inclined roller plate 16 can be accurately controlled to ensure that the peppers can enter the subsequent separation process evenly and orderly, which not only improves the cleaning effect, but also effectively avoids the blockage problem caused by the heavy influx of peppers, ensuring the smooth progress of the separation process. At the same time, the use of the flexible roller 1704 can reduce friction and impact when the peppers come into contact with it during the sliding process, thereby reducing the damage rate of the peppers.

[0054] For further information, see Fig.12 , Fig.13 and Fig.15 The air supply component 21 includes: a chassis plate 2101, which is installed on the front lower side of the auxiliary frame 15; two air pumps 2102 are provided, which are respectively installed on the left and right sides of the top of the chassis plate 2101; two groups of exhaust branch pipes 2103 are provided, which are respectively installed on the left and right sides of the auxiliary frame 15, and the air inlet end of the exhaust branch pipe 2103 is connected with the exhaust port of the corresponding air pump 2102, and the exhaust branch pipe 2103 has two exhaust ends, one of which is connected to the wind blowing plate 20, and the other is connected to the downwind exhaust port 25; airflow regulating valves 2104 are respectively installed on the two exhaust ends of the exhaust branch pipe 2103.

[0055] By installing two air pumps 2102, it is ensured that the air supply component 21 can provide a stable and sufficient airflow, which meets the wind force demand of the wind-blown plate 20 and provides additional wind support for the downwind outlet 25. Secondly, the setting of the airflow regulating valve 2104 can flexibly adjust the exhaust volume of the branch pipe 2103, thereby realizing the adjustment of the wind force size of the wind-blown plate 20 and the downwind outlet 25, and also realizing the different wind force sizes of the wind-blown plate 20 and the downwind outlet 25.

[0056] For further information, see Fig.13 and Fig.15 Three speed bumps 26 are equidistantly mounted at the front center of the top of the inclined rolling plate 16, and the speed bumps 26 are all made of plastic.

[0057] The main function of the speed bumps 26 is to slow down the speed at which the peppers slide on the inclined roller plate 16. By increasing the friction, they ensure that the peppers can slide in a more stable and orderly manner, thereby effectively avoiding accumulation, collision or damage problems that may be caused by excessive speed. In addition, the appropriate sliding speed also helps to disperse the peppers more evenly on the inclined roller plate 16, thereby improving the work efficiency of the subsequent cleaning and separation process.

[0058] For further information, see Figure 12-Figure 15 The wind force of the wind blowing plate 20 is greater than the wind force of the downwind outlet 25, and the wind force of the downwind outlet 25 is directed vertically downward toward the middle of the leaking inclined box 18.

[0059] Through the strong wind force released by the wind-blowing plate 20, the peppers sliding on the inclined rolling plate 16 can be blown and transferred more effectively. In this process, the strong wind force also promotes the shedding of impurities on the surface of the peppers. At the same time, the wind force released by the downwind outlet 25, although smaller than the wind force of the wind-blowing plate 20, plays a key role in isolating dust and separating shriveled and inferior peppers, and will not interfere with the normal wind transport of the wind-blowing plate 20 to the peppers. It not only ensures that the peppers can be separated smoothly according to the predetermined trajectory and speed during the sliding process, but also significantly improves the removal efficiency of impurities and dust on the surface of the peppers, and realizes the quality sorting of the peppers.
