[0002] Bamboo plants are widely distributed in the hilly areas of southern my country. Bamboo shoots, as the young shoots of bamboo, have a unique taste and are rich in various nutrients. They are a traditional Chinese delicacy and are very popular among people. Traditional Chinese medicine believes that bamboo shoots are sweet, slightly cold, and non-toxic. They have the medicinal effects of clearing heat and resolving phlegm, invigorating qi and harmonizing the stomach, treating thirst, promoting urination, and relieving diaphragm and refreshing the stomach. Small-path bamboo shoots are a common type of bamboo shoots in Jiangsu and Zhejiang provinces. They are slender and conical in shape, with loose shells and small size. The bottom diameter is between 1 and 5 cm, the length is between 20 and 50 cm, and the thickness of the shell is roughly 1 to 3 mm.

[0003] Bamboo shoots and their products are the second largest category of products developed from bamboo resources.

DETAILED DESCRIPTION

[0032] The present invention will be further described and illustrated below with reference to the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention may be combined accordingly, provided that there is no conflict between them.

[0033] In the present invention, unless otherwise specified, the direction referred to by “rear” is Figure 1 On the left side, “transport direction” refers to Figure 1 The direction from right to left.

[0034] like Figures 1 to 3 As shown, an efficient shelling device for processing small-diameter bamboo shoots provided by the present invention is provided. The device is mainly composed of a frame 2, a bamboo shoot conveying device, a bamboo shoot positioning device, a bamboo shoot shell cutting device and a bamboo shoot shell stripping device, wherein the bamboo shoot conveying device, the bamboo shoot positioning device, the bamboo shoot shell cutting device and the bamboo shoot shell stripping device are installed on the frame 2; the bamboo shoot conveying device is used to convey bamboo shoots 46 to the rear, and a bamboo shoot shell stripping device is provided at the end, and the two cooperate to realize the separation of the shell and meat of the bamboo shoots 46; the bamboo shoot positioning device and the bamboo shoot shell cutting device are both located above the bamboo shoot conveying device, and are arranged in sequence along the conveying direction; the bamboo shoot positioning device is used to position the bamboo shoots 46 in the vertical and horizontal directions, and the bamboo shoot shell cutting device is used to cut the bamboo shoot shells.

[0035] In practical applications, in order to make the device of the present invention more convenient to move, universal wheels 1 can be provided at each supporting foot at the bottom of the frame 2 .

[0036] The structure and connection method of each device will be described in detail below with reference to the embodiments.

[0037] In this embodiment, the bamboo shoot conveying device is mainly composed of a first motor 9, a third sprocket 6, a fourth sprocket 11, a second chain 8, an active conveying shaft 12, a driven conveying shaft 16 and a conveyor belt 10. Specifically, the first motor 9 is fixed to the frame 2 by screws, the active conveying shaft 12 and the driven conveying shaft 16 are fixed to the frame 2 by bearings, the third sprocket 6 is installed on the output shaft of the first motor 9, the fourth sprocket 11 is installed on the protruding end of the active conveying shaft 12, and the two sprockets are connected by the second chain 8. The conveyor belt 10 is installed on the active conveying shaft 12 and the driven conveying shaft 16, so that the first motor 9 drives the rotation of the conveying shaft to push the bamboo shoots on the conveyor belt 10 forward.

[0038] In this embodiment, if Figure 4 As shown, the bamboo shoot positioning device mainly consists of a guide roller 23, a guide roller 27, a positioning device mounting plate 19, an upper roller mounting plate 20, a lower roller mounting plate 21, a roller shaft 25, a roller shaft fixing seat 22, a flanged linear bearing 17, a roller connecting rod 24, a connecting rod limit screw 18, a roller mounting plate 34, a gear mounting plate 33, a gear 32, a tension spring 35, a tension spring mounting seat 36, a screw 30, a screw support seat 31, a screw mounting seat 29, a roller mounting seat 26, and a roller mounting rod 28. Specifically, the positioning device mounting plate 19 is a vertical bracket structure fixed to the top of the frame 2 by bolts. The roller upper mounting plate 20 is a horizontal cross plate structure, which is fixed to the positioning device mounting plate 19 by screws. Four flanged linear bearings 17 are fixed to the roller upper mounting plate 20 by screws. Four roller connecting rods 24 are installed in the flanged linear bearings 17. The lower half of the roller connecting rod 24 is connected to the roller lower mounting plate 21. The connecting rod limit screws 18 are installed at both ends of the roller connecting rod 24 for fixing. The roller shaft fixing seat 22 is fixed to the roller lower mounting plate 21 by screws. The roller shaft 25 is installed in the mounting hole on the roller shaft fixing seat 22. The guide roller 23 is installed on the roller shaft 25 and can rotate freely. The guide roller 23 is a V-shaped roller structure that is thin in the middle and thick at both ends. By adjusting the interval between it and the conveyor belt 10 below, the bamboo shoots 46 can be positioned vertically and horizontally. As shown Figure 5As shown, two gear mounting plates 33 are fixed to the positioning device mounting plate 19 via screws. Two gears 32 are mounted on the gear mounting plates 33 and mesh with each other, with the rotational axes of the two gears 32 lying on the same horizontal plane. Two roller mounting plates 34 are mounted on the gear mounting plates 33 and secured to the gears 32 via screws, allowing the roller mounting plates 34 to rotate synchronously with the corresponding gears. Two tension spring mounting blocks 36 are respectively fixed to the two roller mounting plates 34 and connected by tension springs 35. A screw mounting block 29 is fixed to one roller mounting plate 34, and a screw support block 31 is fixed to the other roller mounting plate 34. One end of a screw 30 is fixed to the screw mounting block 29, while the other end faces and presses against the screw support block 31. The screw 30 is located below the tension spring 35, ensuring that the two roller mounting plates 34 have an initial angle when no bamboo shoots 46 are passing through. Two roller mounts 26 are screwed to the bottom of the roller mounting plate 34. Two roller mounting rods 28 are fixed to the two roller mounts 26. Two guide rollers 27 are mounted on the two roller mounting rods 28. The guide rollers 27 can freely rotate about the length of the roller mounting plate 34. The guide rollers 23 thus position the bamboo shoots vertically and horizontally perpendicular to the conveying direction, while the guide rollers 27 position the bamboo shoots horizontally perpendicular to the conveying direction.

[0039] In this embodiment, if Figure 6 As shown, the bamboo shoot shell cutting device mainly consists of a circular blade 40, a blade shaft 39, a blade gasket 44, a blade baffle 45, a blade nut 43, a blade connecting plate 41, a cantilever pin 42, a third motor 37, and a motor mounting plate 38. Specifically, the circular blade 40 is mounted on the blade shaft 39, and two blade baffles 45 are mounted on both sides of the circular blade 40 on the blade shaft 39, maintaining a certain distance between the blade gasket 44 and the circular blade 40. The two ends of the blade baffle 45 are locked by the blade nut 43, and the two ends of the blade shaft 39 are fixed to the two blade connecting plates 41 by bearings. The two blade connecting plates 41 are mounted on the positioning device mounting plate 19 by cantilever pins 42 and can rotate freely. The third motor 37 is mounted on a blade connecting plate 41 through the motor mounting plate 38 and is connected to the blade shaft 39 through the thread of the output shaft, thereby achieving the purpose of cutting the bamboo shoot shell along the direction of bamboo shoot transportation.

[0040] In this embodiment, if Figure 1As shown, the bamboo shoot hulling device primarily consists of a hulling roller 15, a roller shaft 14, a second motor 4, a first sprocket 5, a second sprocket 13, and a first chain 7. Specifically, the second motor 4 is fixed to the frame 2 via screws, the roller shaft 14 is mounted on the frame 2 via bearings, and the hulling roller 15 is fixed to the roller shaft 14 via set screws. The first sprocket 5 is mounted on the output shaft of the second motor 4, and the second sprocket 13 is mounted on the protruding end of the roller shaft. The two sprockets are linked by the first chain 7. Consequently, the rotation of the hulling roller 15 driven by the second motor 4 draws the cut bamboo shoot husks between the hulling roller 15 and the conveyor belt 10, achieving separation of the bamboo shoot husks from the flesh.

[0041] Example 1

[0042] This embodiment provides an efficient shelling device for processing small-diameter bamboo shoots, comprising a frame, a bamboo shoot conveying device, a bamboo shoot positioning device, a bamboo shoot shell cutting device, and a bamboo shoot shell peeling device. A pair of guide plates 3 are mounted on the frame, with a spacing of approximately 50 mm between the two guide plates, to prevent the bamboo shoots from deflecting during bamboo shoot shell cutting and peeling. The bamboo shoot conveying device is mainly used to push the bamboo shoots on the conveyor belt 10 forward. The conveyor belt 10 has a forward speed of 0.3 to 0.5 m / s, and its surface is made of rubber material with a high friction coefficient to ensure that sufficient driving force is given to the bamboo shoots during operation. The bamboo shoot positioning device positions the bamboo shoots during bamboo shoot shell cutting using guide rollers 23 and guide drums 27. The bamboo shoot shell cutting device achieves bamboo shoot shell cutting using a rotating circular blade 40. The bamboo shoot shell peeling device achieves bamboo shoot shell peeling using a shelling roller 15 that rotates in the opposite direction to the active conveying shaft 12.

[0043] like Figure 4 and Figure 5 As shown, in the bamboo shoot positioning device, two guide rollers 27 are respectively mounted on two roller mounting rods 28 , and the two roller mounting rods 28 are respectively fixed on two roller mounting plates 34 through roller mounting seats 26 . Figure 3The left-center roller mounting plate 34 is mounted with a screw 30 via a screw mounting seat 29. The other end of the screw 30 rests on a screw support seat 31 mounted on the right-center roller mounting plate 34. The ends of a tension spring 35 are mounted on two tension spring mounting seats 36, respectively fixed to the two roller mounting plates 34. The two roller mounting plates 34 are respectively mounted on two gears 32 on two gear mounting plates 33, with the two gears 32 meshing with each other. When no bamboo shoots are passing, the two guide rollers 27, under the action of the screw 30, maintain an angle of 2° to 8° and a bottom-to-bottom spacing of 5mm to 10mm. The bottoms of the guide rollers 27 maintain a spacing of 2mm to 5mm from the conveyor belt 10. The guide rollers 23 are mounted below the roller mounting plate via four roller connecting rods 24, each with a connecting rod set screw 18 at each end. The roller connecting rods 24 are free to move up and down in flanged linear bearings 17, while the guide rollers 23 are free to rotate about the roller shaft 25. When no bamboo shoots pass through, the bottom of the guide roller 27 and the conveyor belt 10 maintain a spacing of 2 mm to 5 mm.

[0044] like Figure 7 As shown, during the operation, the bamboo shoots are first placed on the conveyor belt 10, with the shoot tips aligned with the gap between the two guide rollers 27. Under the action of the conveyor belt 10, the bamboo shoots first pass through the guide rollers 27. Because the diameter of small-diameter bamboo shoots is typically smaller at the front and larger at the back, the two roller mounting plates 34 gradually open as the bamboo shoots pass through, and the two guide rollers 27 rotate in the direction of the bamboo shoots' passage. Thanks to the presence of the gear 32, the two roller mounting plates 34 open at the same angle, acting as a position limiter for the bamboo shoots, ensuring they are centered in their position and prevent left-right deviation. Next, the bamboo shoots continue to pass through the guide rollers 23. As the bamboo shoots pass through, the roller lower mounting plate 21, roller shaft mounting base 22, guide rollers 23, roller connecting rods 24, and roller shaft 25 gradually rise under the action of the bamboo shoots, and the guide rollers 23 rotate in the direction of the bamboo shoots' passage. Because the guide rollers 23 have a diameter characteristic of being smaller in the middle and larger at the edges, they serve as a position limiter for the conical bamboo shoots, ensuring they are centered in their position and prevent left-right deviation. The guide roller 23 and the guide drum 27 are limited in front and behind to ensure that the bamboo shoots are oriented in the same direction as the forward direction when the bamboo shoot shells are cut, without deviation.

[0045] like Figure 1 and Figure 8As shown, the bamboo shoot cutting device is mounted on the frame via a cantilever pin 42 and is freely rotatable about the cantilever pin. The circular blade 40 is positioned directly in the center of the conveyor belt 10, perpendicular to the direction of bamboo shoots' travel. A blade spacer 44 and two side blade guards 45 maintain a spacing of 2 to 4 mm. The blade shaft 39 is secured to the blade shaft 39 via two blade nuts 43. The blade shaft 39 is mounted on two blade connecting plates 41 via bearings. A third motor 37 is secured to one of the blade connecting plates 41 via a motor mounting plate 38. Its output shaft is connected to the blade shaft 39 via threads and a retaining nut. The blade guard 45 has a diameter 4 to 6 mm smaller than that of the circular blade 40, resulting in a protruding blade length of 2 to 3 mm. This effectively limits the cutting depth, ensuring that the bamboo shoots are cut without damaging the flesh. When no bamboo shoots are passing, the blade shaft 39 rests on the frame 2, with the lower end of the circular blade 40 maintaining a spacing of 2 to 5 mm from the conveyor belt 10.

[0046] like Figure 7 and Figure 8 As shown, during operation, the blade shaft 39, circular blade 40, and blade baffle 45 rotate in the direction of the bamboo shoots' passage at a speed of 120-180 rpm, driven by the third motor 37. As the bamboo shoots pass, the bamboo shoot shell cutting device gradually rises under the action of the bamboo shoots, slicing the bamboo shoot shell at the radial center of the shoots along their forward direction. During the cutting process, a pair of guide plates 3 located on the frame 2 also limit the bamboo shoots, preventing them from deflecting.

[0047] like Figure 1 and Figure 8 As shown, in the bamboo shoot hulling device, the hulling roller is fixed to the roller shaft 14 via a set screw. The angle between the axis of the hulling roller and the hulling roller 15 and the horizontal direction is approximately 60 degrees, and the surface is made of a rubber material with a high friction coefficient. The roller shaft 14 is mounted on the frame 2 via a bearing. During operation, the roller shaft 14 and the hulling roller 15 rotate in the opposite direction of the active conveyor shaft 12 under the action of the second motor 4, at a speed of 10 to 30 rpm. As the bamboo shoots pass through, the bamboo shoot tips and hulls are drawn into the gap between the hulling roller 15 and the conveyor belt 10. The bamboo shoot flesh passes over the hulling roller 15 in the original direction, achieving the separation of the bamboo shoot flesh and the hull. The bamboo shoot hulling device has strict requirements on the minimum spacing between the hulling roller 15 and the conveyor belt 10. If the spacing is too small, the bamboo shoot hulls cannot be drawn in, causing the bamboo shoots to get stuck. If the spacing is too large, the bamboo shoot flesh will be drawn in as well. When the spacing is 5 to 8 mm, a good hulling effect can be achieved. The "spacing" here refers to the distance between the two arcs formed by the radial cross-section of the hulling roller 15 and the conveyor belt 10 in the direction of the line connecting their centers, that is, the shortest straight-line distance between the two.

[0048] like Figure 1As shown, if the bamboo shoot positioning device described above cannot achieve a good positioning effect, you can try increasing the spring constant of the tension spring 35 and adding counterweights to the roller connecting rod 24 and the roller lower mounting plate 21. If the bamboo shoot positioning device described above hinders the transportation of bamboo shoots, you can try reducing the spring constant of the tension spring 35, increasing the length of the screw 30, and increasing the distance between the guide roller 23 and the conveyor belt 10.

[0049] like Figure 1 Shown and Figure 8 As shown, the horizontal spacing between the blade shaft 39 and the roller shaft 14 is 80 to 110 mm, so that the blade presses the rear end of the bamboo shoots during the shelling process, effectively preventing the bamboo shoots from being drawn into the shelling roller 15 and the conveyor belt 10, and improving the success rate of shelling.

[0050] Example 2

[0051] In this embodiment, the same symbols are given to the same structures as in Example 1, and the same descriptions are omitted. This embodiment is improved on the basis of Example 1, and the second motor 4 and its related sprocket chain mechanism are deleted, and mutually meshing gear structures are installed at the protruding ends of the roller shaft 14 and the active conveying shaft 10, with a reduction ratio of 2:1, thereby reducing the number of motors and power supplies required for the device and improving practicality.

[0052] The embodiment described above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Persons skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent substitution or equivalent transformation falls within the scope of protection of the present invention.
