Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a multi-channel positioning circumferential scoring Yangbi walnut shelling machine. Background Art

[0002] Yangbi soaked walnuts are a specialty of Yangbi Yi Autonomous County, Dali Bai Autonomous Prefecture, Yunnan Province, China. They are renowned for their large size, thin shell, white kernel, fragrant flavor, and rich nutrition. By 2023, the cultivated area of ​​Yangbi walnuts stabilized at 1.07 million mu (approximately 1.07 million mu), with an annual output of 92,200 tons and a total output value of 2.966 billion yuan.

[0003] Deep-grained walnuts are one of the two major cultivated varieties of walnut in my country, primarily cultivated in Yunnan Province and its surrounding areas. Yunnan is also my country's largest walnut production region. Among them, the Yangbi Pao Walnut is known for its large nut, thin shell, white kernel, fragrant flavor, and rich nutrition. It is the variety with the largest planting area and production in Yunnan Province. Yangbi Pao Walnuts have deep grain, a small gap between the shell and the kernel, and an irregular shape (the vertical and horizontal diameters of Yangbi Pao Walnuts are equal, but larger than the ridge diameter). This makes them difficult to shell and has a low kernel recovery rate. Therefore, the development of a shelling machine specifically for Yangbi Pao Walnuts is of great significance to the development of Yunnan's walnut industry.

[0004] Existing walnut shelling machines include Patent No. 202210810089.2, titled "A drop-hammer walnut shelling machine with adjustable shelling force," which can adjust the height of the drop hammer so that each walnut can obtain the corresponding shelling force; Patent No. 201910936244.3, titled "A chain-driven walnut laser notching machine," which uses laser notching to ensure high-quality notching; Patent No. 201810104723.4, titled "A fully automatic mechanical walnut notching machine," which uses PLC control to automatically pre-process the walnuts; and Patent No. 202311524732.6, titled "A walnut shelling machine with self-screening function," which can effectively improve the shelling quality of walnuts by adjusting the extrusion force between the extrusion rollers. However, the above shelling and notching pre-processing equipment is mainly aimed at walnuts with regular shapes, such as Xinjiang walnuts, and can achieve good shelling results.

[0005] The suture surface of Yangbi bubble walnut is perpendicular to the horizontal plane in a stable state. Therefore, when cutting along the suture line of Yangbi bubble walnut, the first walnut kernel is likely to appear. Summary of the Invention

The feeding box 201 includes an upper feeding hopper 201a and a lower feeding buffer box 201b. The feeding buffer box 201b is mounted on the upper longitudinal beam 101 of the lower frame. The front end of the feeding plate 202 is fixed to the feeding buffer box 201b through a bayonet, and the feeding plate 202 is fixed to the transverse short flat steel 102 of the lower frame by bolts. (n-1) partitions 202a are evenly arranged side by side inside the feed plate 202, dividing the inner cavity of the feed plate 202 into n channels. The width of each channel is slightly larger than the maximum diameter of the walnut, so that each channel can only accommodate one walnut to pass through; the height of the feed buffer box 201b is equal to the height of the partition 202a of the feed plate 202 and slightly larger than the maximum diameter of the walnut, so that the feed buffer box can only accommodate one walnut to enter the feed plate 202 at the same time in the vertical direction.

[0042] The brush roller 203 is located directly behind the feed plate 202 and directly above the conveying front end of the conveying device 3. The brush roller 203 is fixedly connected to the brush roller bearing seat 205 of the transverse flat steel 102 through the brush roller bearings 204 at both ends.

[0044] Specifically, internal threaded holes are processed on the chain group 303 corresponding to the core holding component and located on the side of the chain group connecting belt 304. The number of internal threaded holes is the same as the number of core holding component units. Correspondingly, the chain group connecting belt 304 is hollowed out with circular holes that are the same in number, size, and connected as the internal threaded holes in the chain group 303, which are used to fix the core holding component units 311.

[0045] Each core holding component unit 311 includes a core holding tray 307, a core holding lower end 309 and a core holding bearing 308 for connecting the core holding tray 307 and the core holding lower end 309. The core holding bearing 308 allows the core holding tray 307 to rotate relative to the core holding lower end 309. The core holding lower end 309 is processed with an external thread. The external thread of the core holding lower end 309 passes through the circular hole of the chain group connecting belt 304 and is screwed into the internal threaded hole of the chain group 303, thereby fixing the core holding component unit 311 to the chain group 302. The size of the core holding tray 307 is slightly smaller than the minimum diameter of the walnut, and cooperates with the core fixing device 4 to fix the walnut.

[0046] The lower end of the feed plate 202 is located above the walnut tray 307, so that the walnuts can smoothly enter the walnut tray 307 from the feed plate 202 without interference.

[0047] Figure 4 The power transmission device 6 shown includes a chain drive consisting of a driven sprocket 605, a driving sprocket 606 and a chain 604, a groove wheel 601, a thumbwheel 603 and a motor 607 installed concentrically with the driving shaft 301, the groove wheel 601 is fixed to the driving shaft 301 by the groove wheel pin 602, so that the driving shaft 301 rotates with the rotation of the groove wheel 601; the connecting pipe of the driven sprocket 605 is sleeved on the thumbwheel fixed shaft of the transverse connecting steel 103, so that the driven sprocket 605 can rotate freely around the thumbwheel fixed shaft, the thumbwheel 603 is sleeved on the connecting pipe of the driven sprocket 605, and the thumbwheel 603 rotates with the rotation of the driven sprocket 605; the driving sprocket 606 is sleeved on the output shaft of the motor 607, and transmits power to the thumbwheel 603 under the drive of the motor 607. The thumbwheel 603 and the groove wheel 601 form a groove wheel intermittent motion mechanism, which performs intermittent motion under the drive of the driven sprocket 605.

[0048] like Figure 5 、 6As shown in Figures 7 and 8, the core fixing device 4 includes n core fixing device units and a telescopic connecting frame 408. The n core fixing device units are evenly arranged side by side on the core fixing device mounting frame 8, and are arranged one-to-one corresponding to the core holding component units 311 in each row; each core fixing device unit includes a telescopic part and a core fixing part, the telescopic part is located directly in front of the core fixing part, and both the telescopic part and the core fixing part are connected to the telescopic connecting frame 408. The telescopic part includes a telescopic motor 413 fixed to the upper layer of the core-fixing device mounting frame 8, a telescopic shaft 409 and a telescopic shell 410 clamped to the lower layer of the core-fixing device mounting frame 8. The telescopic shell 410 is formed by two telescopic shell units, and the top of the telescopic shaft 409 is inserted into the cavity formed by the two telescopic shell units until it is connected to the output shaft of the telescopic motor 413; a telescopic shell unit rack is machined on the inner wall of each telescopic shell unit, and correspondingly, a telescopic shaft rack corresponding to the telescopic shell unit rack is machined on the outer circumferential surface of the telescopic shaft 409, and the telescopic shaft rack is engaged with the telescopic shell unit rack through the telescopic pinion 411, and the telescopic pinion 411 is fixed to the inner wall of the telescopic shell unit through the telescopic gear frame 412; driven by the telescopic motor 413, the telescopic shaft 409 realizes up and down movement relative to the telescopic shell 410 through the telescopic pinion 411.

[0049] The solid core part includes a rotating shaft motor 401 fixedly connected to the upper layer of the solid core device mounting frame 8, a bevel gear 402 connected to the output shaft of the rotating shaft motor 401, a bevel gear rotating shaft 403 connected to the bevel gear 402, and a telescopic rotating shaft 404 coaxially connected to the bevel gear rotating shaft 403. The rotating shaft motor 401 drives the bevel gear 402 to rotate, and the bevel gear 402 drives the bevel gear rotating shaft 403 to rotate, which is used to transmit the power of the rotating shaft motor 401 to the telescopic rotating shaft 404, driving the telescopic rotating shaft 404 to rotate; the telescopic rotating shaft 404 is coaxially installed with the lower end slot of the bevel gear rotating shaft 403 through the vertical slot head inside the upper end, and the telescopic rotating shaft 404 rotates synchronously with the bevel gear rotating shaft 403 while realizing up and down movement relative to the bevel gear rotating shaft 403.

[0050] At the same time, the bottom end of the telescopic shaft 409 passes through the telescopic connecting frame 408, and the telescopic shaft 409 is fixed to the telescopic connecting frame 408 at the lower end through two clips; the telescopic rotating shaft 404 is installed in the annular groove head inside the front end of the telescopic connecting frame 408 through the annular groove in the middle. Driven by the telescopic motor 413, the telescopic shaft 409 drives the telescopic connecting frame 408 to move up and down, so that the telescopic rotating shaft 404 can move up and down under the drive of the telescopic connecting frame 408, and the telescopic rotating shaft 404 can rotate freely relative to the telescopic connecting frame 408.

[0051] Specifically, the lower end of the telescopic shaft 404 is processed with a telescopic shaft fixing plate, and the upper end of the core fixing tray 407 is processed with a core fixing tray fixing plate. The telescopic shaft fixing plate and the core fixing tray fixing plate are connected by multiple groups of spring assemblies, and the multiple groups of spring assemblies are evenly distributed along the circumference. Each group of spring assemblies includes a spring shaft 405 and a spring 406 sleeved on the spring shaft 405. The top of the spring shaft 405 passes through the telescopic shaft fixing plate and is locked by a nut. The bottom end of the spring shaft 405 passes through the core fixing tray fixing plate and is connected by a nut but not locked. On the one hand, the core fixing tray 407 is connected to the telescopic shaft 404 through the spring shaft 405. On the other hand, the spring 406 and the spring shaft 405, under the premise of ensuring the fixing efficiency of the core fixing device 4 to the walnut, effectively adjust the fixing problem caused by walnuts of different sizes through the expansion and contraction of the spring 406 and alleviate the vibration generated when the walnut is cut.

[0052] The shape of the core fixing tray 407 is consistent with that of the core receiving tray 307, both of which are oval and can fit the surface of the walnut to the greatest extent.

[0053] like Figure 8 、 9 As shown, the notching device 5 includes a fixture 504 installed inside the guide fixture 104 at the rear end of the lower frame, n notching device units, two sets of cam motion devices, and two sets of scissor-type telescopic devices 509. The notching device units are arranged in a one-to-one correspondence with the core portion. The notching device units include a blade shaft 510 that vertically passes through the front end of the fixture 504, a double-layer blade 503 fixed to the blade shaft 510 via a blade shaft shoulder 502, and a blade motor 501 that drives the blade shaft 510. The blade motor 501 is fixed to the front end of the fixture 504 by bolts. The double-layer blade 503 is designed to be circular and simultaneously cuts two notches on the walnut during operation. Under the action of centrifugal force and the double-layer blade 503, the walnut will be easily split into two at the notch.

[0054] Two sets of cam motion devices are symmetrically installed on both sides of the rear part of the guide fixing member 104. Each set of cam motion devices includes a cam motor 508 fixed to the cam motor frame of the lower frame, a cam shaft 507 installed on the cam bearing frame, and a cam 505 fixed to the cam shaft 507 through a cam shaft pin 506. The cam shaft 507 is fixed to the output shaft of the cam motor 508.

[0055] Two sets of scissor-type telescopic devices 509 are arranged corresponding to two sets of cam motion devices. The front end of each set of scissor-type telescopic devices 509 is connected to the rear end of the clamp 504, and the rear end is fixed to the rear end of the cam motion device, and the cam 505 is tangent to the scissor-type telescopic device 509. Driven by the cam 505, the scissor-type telescopic device 509 will drive the clamp 504 to reciprocate. At the same time, under the restriction of the guide fixing member 104, the clamp 504 moves repeatedly along the movement direction of the walnut.

[0056] like Figure 10 The working principle of the present invention is shown as follows:

[0057] The walnuts are first placed in the feed box 201. Under the constraint of the feed plate 203, the walnuts are guided to fall into the kernel holding component of the conveying device 3 by controlling the rotation direction and speed of the brush roller 204. At the same time, the intermittent motion mechanism composed of the dial wheel 603 drives the groove wheel 601 to start driving the conveying device 3 to perform intermittent work in the positive direction.

[0058] Before the machine is running, the telescopic shaft 409 of the core fixing device 4 is at the top, and the clamp 504 of the notching device 5 is at the farthest end; when the walnuts are transported to the bottom of the core fixing tray 407 of the core fixing device 4, the conveying device 3 stops moving, and the telescopic shaft 409 drives the telescopic rotating shaft 404 to move downward through the telescopic connecting frame 408. Driven by the telescopic rotating shaft 404, the core fixing tray 407 moves downward and slightly collides with the walnuts, compacting the walnuts downward while cooperating with the core holding component unit of the conveying device 3 to fix the walnuts. The spring 406 and the spring shaft 405 will cooperate with the core fixing tray 407 according to the outer contour of the walnut to reach the optimal fixed position and slow down the vibration caused by the slight collision of the core fixing tray 407 with the walnuts; at this time, the bevel gear rotating shaft 403 drives the telescopic rotating shaft 404 to rotate, and driven by the telescopic rotating shaft 404, the core fixing tray 407 drives the core holding tray 307 and the walnuts to start rotating.

[0059] At the same time as the core fixing device 4 starts to work, the cam movement mechanism drives the scissor-type telescopic device 509 to work, driving the double-layer blade 503 to move toward the walnut, and at this time the double-layer blade 503 starts to rotate; when the scissor-type telescopic device 509 contacts the working contour surface of the cam 505, the double-layer blade 503 continuously cuts the rotating walnut, thereby achieving circumferential cutting.
