Description

Technical Field

[0001] This invention belongs to the field of peanut machine technology, and in particular relates to a special head device for the large drum blades of a peanut machine. Background Technology

[0002] my country is a major consumer of peanuts and the world's largest consumer of peanut oil. As an economic crop, peanuts can yield up to 50% oil. Peanut planting and production technology has always been highly valued. Peanut harvesters, as a type of agricultural machinery for harvesting peanuts, not only greatly reduce labor costs but also significantly improve peanut harvesting efficiency.

[0003] An existing special sleeve for the large drum blades of a peanut machine includes the following structure: CN218163592U discloses a special sleeve for the large drum blades of a peanut machine, including a sleeve and blades. A limiting groove is formed on the outer side of the sleeve, and a limiting sleeve is fitted on the outer side of the blades. The outer side of the limiting sleeve is fixedly connected to one end of a connecting rod. The connecting rod passes through the inner wall of the sleeve through the limiting groove. The other end of the connecting rod is fixedly connected to one side of a fixed rod. The bottom of the fixed rod is fixedly connected to the top of a buffer plate.

[0004] The existing head-mounting device for the large drum cutter teeth of peanut machines still has the following shortcomings:

[0005] 1. The existing device uses an overly simple connection method to fix the large drum cutter teeth, resulting in an unstable connection. Since the working environment of the large drum cutter teeth is relatively complex, the stability of the cutter teeth that are not securely fastened is questionable, which will affect the normal working efficiency of the peanut machine.

[0006] 2. The existing device has low compatibility. It cannot be installed or disassembled when faced with blades of different lengths, which greatly reduces its working efficiency. Furthermore, when the blade length is short, it cannot protect the blade body, and the sleeve cannot function.

[0007] 3. The existing device is difficult to install and disassemble. When the bolts at the bottom of the cutter group are removed, the length of the fixing rod cannot be adjusted. As the bolt position rises, the entire device will fall off the large drum cutter teeth, resulting in poor stability. Summary of the Invention

[0008] The purpose of this invention is to address the problems of unstable connection methods, poor compatibility, and inconvenient disassembly of existing devices mentioned in the background art, and to provide a special head device for the large drum blades of a peanut machine that features stable connection, high compatibility, and convenient installation and disassembly.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a special sleeve device for the large roller blade teeth of a peanut machine, comprising a pair of clamping and fixing shells, wherein an adjusting shell is fixedly connected to one end of each of the two clamping and fixing shells that are close to each other, a transmission mechanism is provided between the adjusting shells, and a clamping and fixing mechanism is provided inside the clamping and fixing shells.

[0010] Furthermore, the clamping and fixing mechanism includes a pair of support shafts fixedly connected inside the clamping and fixing housing. A transmission gear is rotatably connected to the support shafts. A pair of incomplete gears is rotatably connected to the inner wall of the clamping and fixing housing. The two incomplete gears mesh with the transmission gears on their respective sides. A right-angle rod is coaxially fixedly connected to the rotating shaft of the incomplete gears. A fixing rod is fixedly connected to the right-angle rod.

[0011] Furthermore, the clamping and fixing housing has a support opening at its top, and a snap-fit ​​slide rail is provided on the inner wall of the clamping and fixing housing. A double-sided toothed plate is slidably connected to the snap-fit ​​slide rail, and the double-sided toothed plate meshes with two transmission gears respectively. Mounting plates are fixedly connected to the top of the double-sided toothed plate and the ends of the two right-angle rods away from the clamping and fixing housing. A pair of buffer springs are fixedly connected to the mounting plates. A telescopic connecting rod is fixedly connected to the mounting plate on the double-sided toothed plate, and the telescopic connecting rod is located between the two buffer springs. A first clamping plate is fixedly connected to the end of the telescopic connecting rod and the two buffer springs away from the mounting plate. A rotating rod is fixedly connected to the mounting plate on the right-angle rod, and the rotating rod is located between the two buffer springs. A second clamping plate is rotatably connected to the end of the rotating rod away from the mounting plate. Both buffer springs on the mounting plate are fixedly connected to the second clamping plate. A hydraulic cylinder is fixedly connected to the bottom of the clamping and fixing housing, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the double-sided toothed plate. A sliding opening is provided on the clamping and fixing housing for the rotation position of the right-angle rod.

[0012] Furthermore, each of the two adjusting housings has a sliding groove at one end close to the other. The adjusting mechanism includes a drive housing slidably connected to the sliding groove. A cutter sleeve is provided inside the drive housing. A pair of telescopic rods are fixedly connected to the drive housing. A connecting horizontal plate is fixedly connected to the output ends of the two telescopic rods. The connecting horizontal plate is fixedly connected to the two adjusting housings. A main gear and two auxiliary gears are rotatably connected to the connecting horizontal plate. The two auxiliary gears are distributed on both sides of the main gear and mesh with the main gear. A rotating seat is coaxially fixedly connected to the main gear.

[0013] Furthermore, a pair of worm gears are rotatably connected to the bottom of the drive housing. The two worm gears are symmetrically arranged with the cutter head as the axis. The ends of the two worm gears that are close to each other are coaxially fixedly connected to a driven bevel gear. The auxiliary gear is coaxially fixedly connected to a transmission shaft. The transmission shaft passes through and connects the horizontal plate and the drive housing. The end of the transmission shaft away from the horizontal plate is coaxially fixedly connected to a driving bevel gear. The driving bevel gear and the driven bevel gear mesh with each other.

[0014] Furthermore, two worm gears are rotatably connected inside the drive housing, and the two worm gears mesh with the worm on the corresponding side. Both sides of the drive housing have communication openings, and the worm gears and worm are located inside the communication openings. An adjustment toothed plate is fixedly connected inside the adjustment housing, and the adjustment toothed plate meshes with the worm gears.

[0015] Furthermore, the tool sleeve is disposed inside the drive housing, and a matching nut base is connected to the bottom of the tool sleeve.

[0016] Furthermore, both the No. 1 clamping plate and the No. 2 clamping plate are provided with anti-slip pads, and a support rod is fixedly connected to the top of the tool sleeve. The support rod passes through the horizontal plate and is fixedly connected to the main gear on the same axis.

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. By setting up a clamping and fixing mechanism, the present invention can stably fix the device body on the large roller cutter teeth, ensuring the overall stability and firmness of the device, while making the subsequent disassembly and installation of the cutter group safer and more reliable.

[0019] 2. By setting a tool sleeve inside the adjusting housing, the height of the tool sleeve can be increased by adjusting the height of the adjusting housing according to the actual situation, thereby greatly improving the compatibility of the device and making it more convenient and faster to use.

[0020] 3. By setting a main gear and a secondary gear, the connecting bolts on the large roller cutter teeth can be disassembled by rotating the rotating seat. At the same time, the outer shell will rise synchronously to ensure that the bolts are always in the nut base, making the overall installation and disassembly process smoother, faster and more stable.

Detailed Implementation

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0029] like Figures 1-6 As shown, a special head device for large roller blades of a peanut machine includes a pair of clamping and fixing shells 1. An adjusting shell 2 is fixedly connected to one end of each clamping and fixing shell 1 that is close to each other. A transmission mechanism is provided between the adjusting shells 2. A clamping and fixing mechanism is provided inside the clamping and fixing shell 1.

[0030] The clamping and fixing mechanism includes a pair of support shafts 3 fixedly connected inside the clamping and fixing housing 1. A transmission gear 4 is rotatably connected to the support shafts 3. A pair of incomplete gears 5 are rotatably connected to the inner wall of the clamping and fixing housing 1. The two incomplete gears 5 mesh with the transmission gear 4 on their respective sides. A right-angle rod 6 is coaxially fixedly connected to the rotating shaft of the incomplete gears 5. A fixing rod 7 is fixedly connected to the right-angle rod 6. A support opening is provided at the top of the clamping and fixing housing 1. A snap-fit ​​slide rail is provided on the inner wall of the clamping and fixing housing 1. A double-sided toothed plate 8 is slidably connected to the snap-fit ​​slide rail. Plate 8 meshes with two transmission gears 4 respectively. Mounting plates 9 are fixedly connected to the top of the double-sided toothed plate 8 and the ends of the two right-angle rods 6 away from the clamping and fixing housing 1. A pair of buffer springs 10 are fixedly connected to the mounting plates 9. A telescopic connecting rod 29 is fixedly connected to the mounting plates 9 on the double-sided toothed plate 8. The telescopic connecting rod 29 is located between the two buffer springs 10. A clamping plate 12 is fixedly connected to the ends of the telescopic connecting rod 29 and the two buffer springs 10 away from the mounting plates 9. A rotating rod is fixedly connected to the mounting plates 9 on the right-angle rods 6. The rotating rod is positioned between the two buffer springs 10. Between the springs 10, a second clamping plate 13 is rotatably connected to the end of the rotating rod away from the mounting plate 9. Both buffer springs 10 on the mounting plate 9 are fixedly connected to the second clamping plate 13. A hydraulic cylinder 14 is fixedly connected to the bottom of the clamping and fixing housing 1. The output end of the hydraulic cylinder 14 is fixedly connected to the bottom of the double-sided toothed plate 8. A sliding opening is provided on the clamping and fixing housing 1 for the rotation position of the right-angle rod 6. Anti-slip pads are provided on both the first clamping plate 12 and the second clamping plate 13. The anti-slip pads can increase the friction between the surfaces of the first clamping plate 12 and the second clamping plate 13. This makes the connection more stable. When the output end of the hydraulic cylinder 14 extends, it will cause the double-sided toothed plate 8 fixedly connected to it to rise, and cause the two transmission gears 4 meshing with it to rotate, and cause the two incomplete gears 5 to rotate. The right-angle rods 6 fixedly connected to the two incomplete gears 5 on the same axis will rotate and move closer to each other. The mounting plate 9 on the double-sided toothed plate 8 drives the first clamping plate 12 and the second clamping plate 13 on the two right-angle rods 6 to fix the large drum cutter group. The buffer spring 10, together with the rotating rod and the telescopic connecting rod 29, can achieve a certain buffering effect.

[0031] Each of the two adjusting housings 2 has a sliding groove at one end close to the other. The adjusting mechanism includes a drive housing 15 slidably connected within the sliding groove. A cutter sleeve 16 is installed inside the drive housing 15. A pair of telescopic rods 11 are fixedly connected to the drive housing 15. A connecting horizontal plate 17 is fixedly connected to the output ends of the two telescopic rods 11. The connecting horizontal plate 17 is fixedly connected to the two adjusting housings 2. A main gear 18 and two auxiliary gears 19 are rotatably connected to the connecting horizontal plate 17. The two auxiliary gears 19 are distributed on both sides of the main gear 18 and mesh with the main gear 18. A rotating seat 20 is coaxially fixedly connected to the main gear 18. A pair of worm gears 2 are rotatably connected to the bottom of the drive housing 15. 1. Two worm gears 21 are symmetrically arranged with the tool holder 16 as the axis. A driven bevel gear 22 is coaxially fixedly connected to the end of each worm gear 21 that is close to each other. A drive shaft 28 is coaxially fixedly connected to the auxiliary gear 19. The drive shaft 28 passes through the horizontal plate 17 and the drive housing 15, and a driving bevel gear 23 is coaxially fixedly connected to the end of the drive shaft 28 away from the horizontal plate 17. The driving bevel gear 23 meshes with the driven bevel gear 22. Two worm wheels 24 are rotatably connected inside the drive housing 15. The two worm wheels 24 mesh with the corresponding worm gear 21 on one side. A connecting port 30 is opened on both sides of the drive housing 15, with the worm wheels 24 and worm gear 21 partially located within the connecting port 30. Inside the adjusting housing 2, an adjusting toothed plate 25 is fixedly connected. The adjusting toothed plate 25 meshes with the worm gear 24. The cutter sleeve 16 is installed inside the drive housing 15, and a matching nut base 26 is connected to the bottom of the cutter sleeve 16. A support rod 3 is fixedly connected to the top of the cutter sleeve 16. The support rod 3 passes through the horizontal plate 17 and is coaxially fixedly connected to the main gear 18. The matching nut base 26 can be matched with the nut of the cutter set base. When it is necessary to disassemble and install the large roller cutter, the cutter set can be placed into the cutter sleeve 16, so that the nut of the cutter set base matches the matching nut base 26. By placing a right-angle wrench in the rotating seat 20 and rotating... When the main gear 18, which is coaxially fixedly connected to the rotating seat 20, rotates, it causes the two auxiliary gears 19 meshing with it to rotate. The rotation of the main gear 18 causes the tool sleeve 16 connected through the support rod 3 to rotate. The rotation of the auxiliary gears 19 causes the transmission shaft 28, which is coaxially fixedly connected with it, to rotate. The driving bevel gear 23, which is coaxially fixedly connected to the transmission shaft 28, will drive the driven bevel gear 22 meshing with it to rotate. As a result, the worm 21 will rotate and drive the worm wheel 24 meshing with it to rotate. Since the worm wheel 24 meshes with the adjusting tooth plate 25, the adjusting housing 2 will rise or fall, thereby realizing the disassembly or installation of the large drum cutter set.

[0032] The working principle of this invention is as follows:

[0033] First, the device needs to be stably connected to the large drum cutter assembly. When the output end of the hydraulic cylinder 14 extends, the double-sided toothed plate 8 fixedly connected to it will rise, and the two transmission gears 4 meshing with it will rotate, and the two incomplete gears 5 will rotate. The right-angle rods 6 fixedly connected to the two incomplete gears 5 will rotate and move closer to each other. The mounting plate 9 on the double-sided toothed plate 8 drives the first clamping plate 12 and the second clamping plate 13 on the two right-angle rods 6 to fix the large drum cutter assembly. The buffer spring 10, together with the rotating rod and the telescopic connecting rod 29, can achieve a certain buffering effect.

[0034] Secondly, the matching nut base 26 can be matched with the nut of the blade assembly base. When it is necessary to disassemble or install the large drum blades, the blade assembly can be placed into the blade sleeve 16, and the nut of the blade assembly base can be matched with the matching nut base 26. By placing the right-angle wrench in the rotating seat 20 and rotating it, the main gear 18, which is coaxially fixedly connected to the rotating seat 20, will rotate, and the two auxiliary gears 19 meshing with it will rotate. The rotation of the main gear 18 will cause the blade sleeve 16 connected through the support rod 3 to rotate, and the rotation of the auxiliary gears 19 will cause the transmission shaft 28, which is coaxially fixedly connected with it, to rotate. The driving bevel gear 23, which is coaxially fixedly connected to the transmission shaft 28, will drive the driven bevel gear 22 meshing with it to rotate, so that the worm 21 will rotate and drive the worm wheel 24 meshing with it to rotate. Since the worm wheel 24 meshes with the adjusting tooth plate 25, the adjusting housing 2 will rise or fall, thereby realizing the disassembly or installation of the large drum blade assembly.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
