Description

Technical Field

[0001] The invention relates to agricultural machinery, in particular to a pepper stem removing device. Background Art

[0002] Chili is a condiment that is deeply loved by people. Its production and demand are increasing year by year. In the process of processing chili, the chili stems need to be removed. The manual removal of chili stems requires a lot of manpower due to the large number of chilies, with high labor intensity and low work efficiency. In addition, the manual removal process will cause certain harm to the health of the operators.

[0003] For this purpose, a mechanical pepper stem removal device has emerged. The existing pepper stem removal device includes a drum with a plurality of sieve holes and a set of roller pairs arranged outside the drum, each set of roller pairs includes two rotating rollers with opposite rotations. After the pepper is placed in the drum, the pepper stems are inserted into the sieve holes during the rotation of the drum. At this time, each set of roller pairs rotates in opposite directions to apply an outward pulling force to the pepper stems, thereby removing the pepper stems.

[0004] The existing device has the following defects: (1) The sieve holes on the drum are more convenient for straight pepper stalks to be inserted. When the pepper stalks are curved, it is very difficult to insert the curved pepper stalks into the sieve holes, resulting in the curved pepper stalks being unable to be removed, greatly reducing the removal efficiency of the pepper stalks; (2) Since the efficiency of removing pepper stalks using sieve holes is not high, people have adopted a method of increasing the size of the drum and thus the sieve holes to improve the effect of removing pepper stalks. However, as a result, the overall volume becomes larger and the structure becomes more complicated, which not only increases the floor space, but also increases the load required for the motor, thereby increasing the cost of the entire pepper stalk removal device.

[0012] The arc-shaped sieve sheets are made of flexible materials, and the gap between the two arc-shaped sieve sheets is adjustable.

[0013] A plurality of fixing rings are arranged at intervals along the axial direction of the sieve cylinder;

[0014] Radial sliding grooves are symmetrically arranged at the two outwardly bent side edges of the flexible sieve plate, and the fixing rings are slidably arranged in the sliding grooves. The sliding grooves are arranged along the radial direction of the sieve cylinder.

[0015] Each group of spiral pair of rollers includes two spiral rollers with opposite rotation directions. The spiral rollers are roller shafts with continuous spiral grooves on the outer surface. The two ends of the roller shafts are respectively rotatably connected to the end cover rings at both ends. The spiral grooves on the two spiral rollers have opposite spiral directions, and the two spiral rollers are symmetrically arranged outside the gap between the two flexible sieve plates;

[0016] The spirals are symmetrically arranged obliquely, and the distance between the spiral pair of rollers and the flexible sieve plate gradually increases from the input end to the output end of the sieve cylinder.

[0037] (5) Since the pepper stalk removal effect of this device is good and the removal efficiency is high, the length of the entire device can be reduced, greatly reducing the floor area of the device. The power drive of the entire device can be realized through a single motor and a planetary gear train. Brief Description of the Drawings

[0050] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation mode of the present invention in conjunction with the accompanying drawings.

[0051] In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation modes disclosed below.

[0052] As Figure 1 shown, the chili stalk-removing device of the present invention includes a frame 1, a stalk-removing mechanism 2 and a power mechanism. The stalk-removing mechanism is arranged on the frame. The stalk-removing mechanism 2 is in a drum shape. The input end of the stalk-removing mechanism is provided with a feed inlet 3, and the bottom of the output end of the stalk-removing mechanism is provided with a discharge outlet. In this embodiment, a conveyor belt 4 is arranged below the discharge outlet. During the rotation of the conveyor belt, the de-stalked chili can be removed in time. At the same time, a power mechanism is arranged outside the output end of the stalk-removing mechanism. The power mechanism is located above the discharge outlet and provides power support for the stalk-removing action of the stalk-removing mechanism through the power mechanism.

[0053] As Figure 2 shown, the stalk-removing mechanism includes a sieve cylinder. The sieve cylinder includes two cover rings and several flexible sieve plates 5 located between the two cover rings. Both cover rings are in a circular ring shape, including an input end cover ring 6 and an output end cover ring 7. Between the input end cover ring 6 and the output end cover ring 7 and along the circumferential direction of the cover ring, several flexible sieve plates are arranged. The flexible sieve plates are arranged along the axial direction of the sieve cylinder. All the flexible sieve plates form a cylinder. During the stalk-removing process, the chili is placed inside the cylinder. There is an axial continuous gap between adjacent flexible sieve plates.

[0054] As Figure 3 shown, the flexible sieve plate includes an arc-shaped sieve piece 8 and a sieve piece shaft 9 located in the middle of the outer side of the arc-shaped sieve piece. The arc-shaped sieve piece 8 protrudes towards the inside of the cylinder, that is, the axial side edges of the arc-shaped sieve piece are bent outwards. The sieve piece shaft 9 is located at the bottom of the concave outer surface of the flexible sieve plate. The sieve piece shaft penetrates through the entire arc-shaped sieve piece, and the arc-shaped sieve piece 8 is rotatably connected with the sieve piece shaft 9.

[0055] The sieve sheet in this application is made of flexible material. During the rotation of the sieve cylinder, due to the action of centrifugal force, the sieve sheet can produce a certain degree of bending deformation, so that the gap between two adjacent flexible sieve plates 5 changes, which is more conducive to the insertion of the curved chili stalks into the gap, thus greatly improving the removal effect of chili stalks.

[0056] In order to improve the connectivity between the flexible sieve plates 5 and ensure the consistency of the actions between the flexible sieve plates, the flexible sieve plates 5 are connected by several fixing rings 10. In this embodiment, several fixing rings 10 are arranged along the axial direction of the sieve cylinder, and each fixing ring passes through the sliding grooves 11 on each flexible sieve plate in sequence, and the fixing ring can slide in the sliding groove.

[0057] In this embodiment, sliding grooves 11 are symmetrically arranged at the outwardly bent two side edges of each flexible sieve plate, and the fixing rings 10 pass through the sliding grooves 11 of each flexible sieve plate in sequence, as Figure 4 shown. Through the fixing rings, it can not only play a constraining role on the flexible sieve plate, generating an inward binding force on the flexible sieve plate; but also play a limiting role on the bending deformation degree of the flexible sieve plate through the sliding of the fixing ring in the sliding groove, enabling the flexible sieve plate to bend and deform within a specified range, thereby limiting the gap between two adjacent flexible sieve plates.

[0058] The centrifugal force generated during the rotation of the sieve cylinder will cause the two side edges of the arc-shaped sieve sheet to produce inward bending deformation. At this time, the distance between two adjacent flexible sieve plates 5 becomes larger. The greater the rotation speed of the sieve cylinder, the greater the bending deformation degree of the arc-shaped sieve sheet, and the distance between two adjacent flexible sieve plates also becomes larger accordingly. At this time, it is more convenient for the chili stalks to be inserted into the gap. When the rotation speed of the sieve cylinder reaches a certain level, the fixing ring 10 will play a limiting role on the deformation of the flexible sieve plate 5, preventing the continuous bending deformation of the flexible sieve plate 5. At this time, the distance between two adjacent flexible sieve plates 5 reaches the maximum. Even if the speed of the sieve cylinder continues to increase, the flexible sieve plate will not continue to produce greater bending deformation, and the distance between two adjacent flexible sieve plates remains unchanged at this time.

[0059] As Figure 5 shown, several groups of spiral counter-rollers are arranged on the outer side of the flexible sieve plate 5, and each group of spiral counter-rollers is arranged on the outer side of the gap between two adjacent flexible sieve plates. Each group of spiral counter-rollers includes two spiral rollers 12 with opposite rotation directions. The spiral roller is a roller shaft with continuous spiral grooves on its outer surface. The two ends of the roller shaft are respectively rotationally connected to the input end cover ring and the output end cover ring, and the spiral grooves on the two spiral rollers have opposite helix directions. The two spiral rollers 12 are symmetrically arranged on the outer side of the gap between two adjacent flexible sieve plates.

[0060] During the process of the two spiral rollers 12 moving towards each other, they will apply an upward and backward clamping force on the chili stalks. The upward clamping force can achieve the removal of the chili stalks, and the backward clamping force will drive the chili to move along with the spiral roller.

[0061] When the chili stalk extends through the gap between the two flexible sieve plates, it will directly insert between the two spiral rollers. Under the action of the upward clamping force formed between the two spiral rollers, an upward pulling force is applied to the chili stalk to achieve the removal of the chili stalk. If the chili stalk is not removed, it will gradually move from the input end of the sieve cylinder to the output end along with the spiral roller. During its movement, an upward pulling force is continuously applied to the chili stalk through the spiral shaft, and finally the removal of the chili stalk will be achieved. After the chili stalk is removed, the centrifugal force generated during the rotation of the sieve cylinder will directly throw the chili stalk away from the device.

[0062] During the removal of the chili stalk, the chili always clings to the inner side surface of the flexible sieve plate. Since the flexible sieve plate is curved, the flexible sieve plate will apply a downward extrusion force to the chili clamped between the two flexible sieve plates. When the chili stalk is removed by the threaded pair of rollers, under the extrusion action of the two flexible sieve plates, the chili located between the two flexible sieve plates will be automatically extruded into the sieve cylinder. Therefore, the chili will not get stuck in the gap between the two flexible sieve plates, effectively preventing the chili from getting blocked at the gap.

[0063] As Figure 6 shown, the distance between the spiral roller 12 and the gap surface between the two flexible sieve plates 5 shows a gradually increasing trend from the input end of the sieve cylinder to the output end of the sieve cylinder. There is a gap between the adjacent side edges of the two flexible sieve plates. The outer surface between the adjacent side edges and the gap between the two outer surfaces form the gap surface. The spiral pair of rollers is inclined. The distance between the spiral pair of rollers and the gap surface at the input end of the flexible sieve plate is the smallest, and the distance between the spiral pair of rollers and the gap surface at the output end of the flexible sieve plate is the largest.

[0064] When the chili stalk is removed by the inclined spiral pair of rollers, as the distance between the spiral pair of rollers and the gap surface continuously increases, the chili stalk is simultaneously subjected to an upward tensile force from the thread groove. At this time, under the dual action of the upward and backward clamping force between the two thread grooves moving towards each other and the upward tensile force of the thread groove, the removal effect of the chili stalk is improved.

[0065] The rear end of the sieve plate shaft 9 is fixedly connected to the output shaft collar 7. The front end of the sieve plate shaft 9 is slidably connected to the input shaft collar 6, and a position adjustment portion is provided at the front end of the sieve plate shaft 9. Through the position adjustment portion, the front end position of the sieve plate shaft can be automatically adjusted, thereby adjusting the angle between the flexible sieve plate 5 and the spiral pair of rollers to adapt to the removal of chili stalks of different lengths.

[0066] In this embodiment, spherical connectors 13 are provided at both ends of the sieve shaft. The spherical connector at the front end of the sieve shaft is arranged in the guiding chute 14 of the input end cover ring 6, and the spherical connector 13 can slide in the guiding chute 14, and the guiding chute plays a guiding role in the sliding of the spherical connector. The spherical connector at the rear end of the sieve shaft 9 is fixedly connected to the output end cover ring 7.

[0067] As Figure 7 shown, the position adjusting part includes an adjusting gear 15, an internal gear ring 16 and a top ring 17. The top ring of the internal gear ring 16 is fixed with a top ring 17, and the outer surface of the top ring 17 is provided with continuous tooth shapes. The inner surface of the input end cover ring 6 is provided with an annular groove 18, and the internal gear ring 16 and the top ring 17 are arranged in this annular groove. In this embodiment, as Figure 8 shown, an arc-shaped guide rail 18 is fixed in the annular groove, and the internal gear ring and the top ring are slidably arranged in this arc-shaped guide rail, and the arc-shaped guide rail plays a supporting role for the internal gear ring and the top ring. Several adjusting gears 15 are arranged inside the internal gear ring, the inner side surface of the internal gear ring 16 is tooth-shaped, and the adjusting gear 15 meshes with the internal gear ring 16, and the adjusting gear 15 plays an auxiliary supporting role for the internal gear ring 16. In this embodiment, the internal gear ring 16 and the top ring 17 can be of an integral structure.

[0068] In this embodiment, the gear shaft of the adjusting gear 15 is rotatably connected to the input end cover ring 6. The adjusting gear includes at least one active adjusting gear 22. One end of the gear shaft of the active adjusting gear 22 is located outside the input end cover ring 6, and a rotating handle 23 is fixed at this end. Through this rotating handle 23, the rotation of the active adjusting gear 22 can be realized. Through the meshing between the active adjusting gear 22 and the internal gear ring 16, power is provided for the rotation of the internal gear ring 16 and the top ring 17.

[0069] A thimble 19 is correspondingly arranged at the spherical connector 13 at the front end of each sieve shaft. As Figure 9 shown, the thimble 19 is rod-shaped and is respectively slidably arranged in the corresponding through holes 20 of the input end cover ring 6. The number of tooth shapes on the outer surface of the top ring 17 corresponds to the number of spherical connectors at the front end of the sieve shaft, and a continuous thimble chute is provided at the annular outer side surface of the tooth shape of the top ring. One end of the thimble is slidably arranged in the thimble chute, and an arc-shaped plate 21 is fixed at the other end of the thimble, and this arc-shaped plate contacts the spherical connector 13 at the front end of the sieve shaft.

[0070] During the rotation of the adjusting gear, through the meshing between the adjusting gear and the internal gear ring, the internal gear ring and the top ring fixedly connected to the internal gear ring are driven to rotate. During the rotation of the top ring 17, the thimble 19 will be pushed to reciprocate radially along the sieve cylinder through the tooth shape on its outside, and at this time the thimble 19 will drive the spherical connector 13 to reciprocate in the guiding chute 14.

[0071] The tooth shape is triangular. In the initial state, the spherical connecting piece is located at one end of the guiding chute. At this time, the ejector pin is located in the groove at the tooth root, and the distance between the flexible sieve plate 5 and the spiral counter-roll is the largest. During the rotation of the adjusting gear, due to the meshing between the adjusting gear and the internal gear ring, the top ring 17 is driven to rotate. At this time, the position of the tooth shape in contact with the ejector pin also changes. At this time, the tooth shape generates an outward pushing force on the ejector pin. At the same time, the ejector pin 19 pushes the spherical connecting piece 13 to move outward along the guiding chute 14, and the distance between the flexible sieve plate 5 and the spiral counter-roll gradually becomes smaller.

[0072] Through appropriate structural design, when the ejector pin is located in the groove at the tooth top, when the spherical connecting piece moves outward to the other end of the guiding chute, the distance between the flexible sieve plate and the spiral counter-roll is the smallest. As the internal gear ring rotates, when the ejector pin moves along the groove on the annular outer surface of the top ring to the tooth root again, the flexible sieve plate automatically resets under the constraint force of the fixed ring, and the sieve shaft automatically moves from one end of the guiding chute to the other end.

[0073] Therefore, the present application can adjust the distance between the flexible sieve plate and the spiral counter-roll according to the actual length of the pepper stalk to be removed, so that the device can be applied to the stalk removal of different types of peppers.

[0074] As Figure 10 shown, the power mechanism includes a motor 24, a triangular fixing plate 25 and a planetary gear train. The planetary gear train includes a sun gear 26, planetary gears 27 and a planet carrier 28. In the present application, planetary gears 27 are respectively provided at the three corners of the triangular fixing plate 25. The body of the motor 24 is fixed on the frame, and the output shaft of the motor 24 is fixedly connected to the sun gear 26. The sun gear 26 and the three planetary gears 27 are in a meshing state with each other. The planet carrier 28 is located on the annular outer surface of the planetary gears 27, and the internal teeth between the planetary gears 27 and the planet carrier 28 are meshed with each other. During the operation of the motor 24, the sun gear 26 is driven to rotate, and power is transmitted through the planetary gear train to drive the planetary gears to rotate.

[0075] The planet carrier 28 is located inside the output end cover ring 7, and the planet carrier 28 and the output end cover ring 7 are fixedly connected by several connecting rods 29. Therefore, when the planetary gears rotate, the output end cover ring 7 can be driven to rotate, thereby providing power for the rotation of the stalk removal mechanism.

[0076] At the same time, gears 30 are respectively fixedly provided at the end parts of the spiral rollers, and the adjacent two gears are in a meshing state with each other. The gear fixed at the end of one of the spiral rollers is a driving gear, and the driving gear is in transmission connection with the output shaft of the motor. In this embodiment, the gear shaft of the driving gear and the output shaft of the motor are connected by a belt drive.

[0077] After the motor 24 transmits power to the driving gear through belt drive, during the rotation of the driving gear, through the meshing between the driving gear and its adjacent gear, the rotation of its adjacent gear is driven, and then through the meshing between the gear and its adjacent gear, the rotation of all the gears fixedly connected to the spiral roller is driven, thereby realizing the rotation of the spiral roller and providing power for the rotation of the spiral roller.

[0078] The working process of the present invention is described as follows. After the chili peppers to be de-stemmed are put into the sieve cylinder through the feed port, the power of the motor is transmitted to the sieve cylinder through the planetary gear train, driving the sieve cylinder to rotate. After the chili peppers are put into the sieve cylinder, during the rotation of the sieve cylinder with the chili peppers, their chili stalks are continuously inserted into the gaps between the adjacent flexible sieve plates 5. After the chili stalks are inserted into the spiral pair rollers through these gaps, the power of the motor 24 is transmitted to the spiral pair rollers through the belt drive system. During the rotation of the two spiral rollers 11 in the spiral pair rollers, an upward and backward clamping force is applied to the chili stalks, and an upward clamping force is continuously applied to the chili stalks until the chili stalks are pulled off from the chili peppers. The removed chili stalks are thrown away from the outer surface of the sieve cylinder under the action of the centrifugal force generated by the rotation of the sieve cylinder. And the chili peppers from which the chili stalks have been removed enter the sieve cylinder again under the squeezing action of the flexible sieve plates 5 on both sides.

[0079] When it is necessary to remove chili stalks of different lengths, the position of the front end of the sieve plate shaft 9 can be adjusted through the position adjustment part. At this time, rotate the rotating handle 23 connected to the driving adjustment gear 22 to make the driving adjustment gear 22 rotate. Through the meshing between the driving adjustment gear 22 and the internal gear ring 16, the internal gear ring 16 and the top ring 17 are driven to rotate. During the rotation of the top ring 17, the ejector pin 19 is driven to move radially along the sieve cylinder through the teeth on the outer side surface, thereby changing the position of the spherical connecting part 13 at the front end of the sieve plate shaft in the guiding chute 14. At this time, the angle between the flexible sieve plate and the spiral pair roller changes, thereby realizing the adjustment of the distance between the flexible sieve plate 5 and the spiral pair roller.
