Description

Technical Field

[0001] The invention relates to the technical field of chestnut processing, in particular to a material conveying system for food processing. Background Art

[0002] Chestnuts, also known as chestnuts and hairy chestnuts, belong to the genus Castanea in the Fagaceae family. They are rich in nutritional value and are mostly processed into sugar-fried chestnuts, chestnut kernels, chestnut cakes, chestnut biscuits and other foods for sale. There are generally two processing methods for processing raw chestnuts into chestnut foods: complete shelling and opening the chestnut shells. Sugar-fried chestnuts only need to be opened without completely shelling. They are popular among consumers because they are easy to eat and have a unique flavor.

[0003] As a nut food, chestnuts have a hard shell, so if you want to cut open the chestnuts, you need a sharp knife. The opening process of chestnuts during processing is mostly done manually with a handheld cutting knife, which makes it difficult to improve the opening accuracy and opening productivity. Moreover, with the increase in demand for chestnuts, manual opening of chestnuts alone can no longer meet market demand.

[0004] In view of the above problems, the prior art provides some solutions. For example, patent publication number CN109730332A provides a chestnut cutting machine, which uses a conveying mechanism to convey chestnuts one by one to the bottom of an opening mechanism, and then squeezes and opens the chestnuts through the opening mechanism. After the extrusion and opening, the material trough is driven to move by a toggle mechanism to realize the conveyance of chestnuts with opened front ends, and at the same time, chestnuts that have not been opened are promptly conveyed to the bottom of the opening knife to facilitate the continuous opening of the chestnuts. The chestnuts should be cut in the center, which can ensure that the chestnuts are heated evenly and prevent bursting during the heating process. There are three states when chestnuts enter the container of the existing device: 1. The plane is downward and the arc surface is upward; 2. The plane is upward and the arc surface is downward; 3. Inclined state. Among the three states, 1 and 2 are both qualified postures for direct cutting, and 3 is an unstable state and the posture needs to be adjusted, as shown in the attached figure of the specification. Figure 8 , among which B and C are qualified postures, while D and E are unstable states. In order to improve the efficiency of chestnut opening, the prior art uses a chain plate to circulate the chestnut plates to the bottom of the opening machine, and then the chestnuts are opened by the opening machine. Then, in order to ensure that the chestnuts can enter the material trough smoothly, the size of the material trough is set to be slightly larger than the size of the chestnuts. Although this method can improve the efficiency of chestnut opening, it is easy to cause the chestnuts to be in an unstable state in the material trough, which will cause the chestnuts to be cut in various postures. When cutting chestnuts in an unstable state, it is easy to open the edge area of ​​the chestnut. When the incision is located in the edge area, it will cause the chestnut to be heated unevenly, which may easily cause some areas to be cooked while other parts are not cooked. At the same time, it is also easy to cause the steam inside the chestnut to be unable to be discharged, thereby causing the chestnut to burst.

[0005] Therefore, a material conveying system for food processing is proposed. Summary of the invention

[0006] The object of the present invention is to provide a material conveying system for food processing, so as to solve the problem that when chestnuts are conveyed to an opening machine, the incision position of the chestnuts is not fixed due to the unstable state, which leads to uneven heating of the chestnuts during processing. The system controls the shaking of the chestnuts in the container when conveying them to the opening machine to adjust their posture, limits the position of the chestnuts, and clamps the chestnuts, so that the middle area of ​​the chestnuts can always be opened.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A material conveying system for food processing, comprising a mounting plate, a servo motor and a rotating roller, and also comprising a support plate, an opening machine, a conveyor belt, a driving mechanism, a container, a transmission mechanism and a clamping piece, wherein the support plate is mounted on one end of the mounting plate, the opening machine is mounted on the top of the mounting plate, the conveyor belt is fitted with the support plate and the rotating roller, the driving mechanism is connected to the support plate and the conveyor belt, the container is connected to the driving mechanism, the transmission mechanism is connected to the container, and the clamping piece is connected to the transmission mechanism, when the servo motor drives the rotating roller to rotate, the conveyor belt drives the container to move cyclically toward the opening machine, and the driving mechanism controls the two containers to move toward each other to clamp chestnuts, and when the two containers move toward each other, the transmission mechanism controls the clamping piece to press the chestnuts and cause the chestnuts to arch upward.

[0009] In the above scheme, the servo motor drives the conveyor belt to rotate by rotating the roller, and then controls the two containers to move toward each other through the driving mechanism to achieve the limitation of the chestnuts, which can prevent the chestnuts from moving significantly in the containers, and at the same time ensure that the chestnuts are located in the center of the two containers, so that it is convenient for the opening machine to open the middle area of ​​the chestnuts. Moreover, as the distance between the chestnuts and the two containers gradually decreases, the transmission mechanism can be used to control the clamping piece to move toward the chestnut, so that the upper end of the chestnut can be squeezed upward, and a certain arch can be generated at the top of the chestnut, which can prevent the chestnut flesh from being damaged when the chestnuts are opened.

[0010] Optionally, when the chestnuts are opened, they may or may not be positioned. Since chestnuts are of different sizes, in order to accommodate all chestnuts, the container for holding the chestnuts will be set relatively large, which will cause the chestnuts to be too loose in the container. As the container gradually moves toward the opening machine, the position of the chestnuts in the container will also change, which will make it impossible for the chestnuts to be accurately aligned with the opening machine, which may easily cause the chestnuts to open at the edge. Positioning the chestnuts and confining them to the center of the container allows the opening process to be performed in the middle area of ​​the chestnuts. Therefore, the chestnuts are opened by positioning them.

[0011] Preferably, the driving mechanism includes a transverse rack, a spur gear, a forward and reverse reciprocating screw, a moving block, a mounting seat and a shaking unit, the transverse rack is installed at the top of the support plate, the spur gear cooperates with the transverse rack, the forward and reverse reciprocating screw is connected to the spur gear, the moving block is connected to the forward and reverse reciprocating screw, the container is installed at the top of the moving block, and the mounting seat is respectively connected to the forward and reverse reciprocating screw and the moving block.

[0012] In the above scheme, when the conveyor belt drives the mounting seat to move, the spur gear and the transverse rack can be controlled to engage, so that the spur gear can drive the forward and reverse reciprocating screw to rotate, so that the two containers can be controlled to move towards each other through the moving block, which can not only reduce the distance between the two containers, but also reduce the distance between the chestnuts and the container trough, and limit the chestnuts to prevent large deviations in the trough. Then, the vibration is controlled by the shaking unit and transmitted to the chestnuts through the container, so that the posture of the chestnuts can be adjusted to prevent the chestnuts from being tilted.

[0013] Preferably, the conveyor belt, container, moving block and mounting seat are symmetrically arranged with two transverse racks as the center, and the spacing between the two conveyor belts is greater than the width of the transverse rack and the spur gear.

[0014] In the above scheme, the conveyor belt can be prevented from interfering with the movement of the transverse rack and the spur gear when rotating, and the smoothness of the operation between the transverse rack and the spur gear can be ensured.

[0015] Preferably, the teeth on the transverse rack are symmetrically arranged, and the teeth are respectively located on one side of the feed end and the discharge end of the opening machine, and the length value of the thread on the forward and reverse reciprocating screw, the circumference value of the spur gear, and the length value of the teeth are consistent.

[0016] In the above scheme, the forward and reverse reciprocating screw can be controlled to rotate twice. One time is before the opening work, by controlling the two containers to move toward each other through the forward and reverse reciprocating screw to reduce the distance between the chestnuts and the containers, so as to position the chestnuts. The second time is after the opening work, by controlling the two containers to move in the opposite direction through the forward and reverse reciprocating screw to increase the distance between the chestnuts and the containers, so as to facilitate the unloading of the chestnuts after opening.

[0017] Preferably, the shaking unit includes a transverse plate, a limiting flow channel, a limiting rod, a piston rod, a sleeve and a spring. The transverse plate is installed at the top of the mounting seat, the limiting flow channel is opened inside the transverse plate, the limiting rod cooperates with the limiting flow channel, the piston rod is connected to the limiting rod, the sleeve is connected to the piston rod, and the sleeve is installed at the bottom of the container, a chamber is opened inside the sleeve, and the spring is installed between the piston rod and the chamber.

[0018] In the above scheme, when the two containers move toward each other, the piston rod can be controlled to move back and forth in the sleeve, and the container can be knocked under the action of the spring elasticity, and the chestnut can be knocked indirectly through the conduction of force. Under the action of the knocking, the chestnut will adjust its posture, which can ensure that the chestnut is in a neat posture for opening processing.

[0019] Preferably, the limiting flow channel comprises a guiding portion and an impact portion, the guiding portion is connected to an adjacent impact portion, the curvature of the guiding portion is smaller than the curvature of the impact portion, and the connection between the guiding portion and the impact portion is arranged to be arc-shaped.

[0020] In the above scheme, the travel path of the limit rod can be limited, and the movement of the limit rod can produce a drop, so that the piston rod can be pulled and the piston rod can be suddenly reset, so that the container can be knocked, thereby generating vibration.

[0021] Optionally, when opening the chestnuts, you can open the chestnuts directly, or you can squeeze the chestnuts at the position where you want to open them to control the chestnut shell to produce a slight bulge. Since the chestnut flesh is relatively full and basically fits the chestnut shell, if the chestnuts are opened directly, it is easy to damage the chestnut flesh, which will affect the subsequent processing of the chestnuts, so the direct opening method is not adopted.

[0022] Preferably, the transmission mechanism includes a longitudinal rack, a driving gear, a driving rod, a connecting rod and a rotating disk, the longitudinal rack is installed on the top of the mounting seat, the driving gear cooperates with the longitudinal rack, the driving rod is respectively installed on one side of the driving gear and the rotating disk, the connecting rod is installed between the two driving rods, the two driving rods are symmetrically arranged about the center line of the connecting rod, a motion groove is opened on the inner wall of the container, and the driving rod, the connecting rod and the rotating disk all cooperate with the motion groove.

[0023] In the above scheme, when the two containers move toward each other, the longitudinal rack can drive the driving gear to rotate. Since the driving rod and the driving gear are eccentrically arranged, and the rotating disk and the driving rod are also eccentrically arranged, the driving gear can control the rotating disk to rotate eccentrically through the connecting rod and another connecting rod during the process of driving the driving rod to move eccentrically, thereby squeezing the clamping piece, thereby controlling the clamping piece to apply pressure to the chestnut, thereby achieving a slight arch in the area to be opened of the chestnut, separating the chestnut shell from the pulp, and avoiding damage to the pulp when opening.

[0024] Preferably, a rotating shaft is provided between the driving rod, the driving gear and the rotating disk. The rotating shaft is located at 1 / 3-1 / 2 of the diameter of the driving gear and the rotating disk. A crescent-shaped protrusion is installed on the rotating disk.

[0025] In the above scheme, this can prevent the clip from making a large movement, thereby preventing the clip from exerting a large force on the chestnut and preventing the chestnut from being deformed due to the force.

[0026] Preferably, the clip is arranged in an arc shape, and two groups of inclined blocks are evenly arranged on one side of the clip, one end of each group of inclined blocks is arranged in an arc shape, the two groups of inclined blocks are inclined upward, one end of each group of inclined blocks is connected by a curve, and the curvature of the clip is greater than the curvature of the end of the inclined block.

[0027] In the above scheme, the direction of the force can be changed when the clamp applies pressure to the chestnut, so that the chestnut can be subjected to an inclined upward force, thereby squeezing the chestnut area to be opened upward, achieving the arching of the chestnut area to be opened, and separating the chestnut shell from the flesh.

[0028] Preferably, the container is bowl-shaped, and a material trough is provided inside the container, the material trough is arranged in a fan shape, and the sum of the radius values ​​of the two material troughs in the container and the distance values ​​of the two conveyor belts is equal to the diameter value of the material trough.

[0029] In the above scheme, it can match the appearance of chestnuts and can store chestnuts.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By controlling the two containers to move toward each other, the distance between the chestnuts and the containers can be shortened, and chestnuts can be prevented from appearing in various places in the material trough. By compressing the placement space of the chestnuts, the chestnuts can be located in the central area of ​​the two containers as much as possible, so that they can correspond to the opening machine, thereby avoiding opening the edge area of ​​the chestnuts, and making the opening of the chestnuts centered to ensure that the chestnuts are evenly heated during processing.

[0032] 2. When the two containers are close to each other, the two clamps can be controlled to move toward each other through the setting of the crank, further reducing the size of the trough, and then the chestnuts are clamped and pressure is applied to the chestnuts. Under the action of pressure, the middle area of ​​the chestnut can be lifted up, so that the shell at the top of the chestnut can be separated from the flesh, and damage to the flesh can be avoided when the chestnuts are opened.

[0033] 3. By bringing the two containers closer to each other, the limiting rod stretches or rebounds the piston rod when it moves in the limiting flow channel, which can produce cyclic knocking on the containers, thereby generating vibrations and transmitting the vibrations to the chestnuts, so that the chestnuts can adjust their postures in the material trough, and the chestnuts can be opened in a neat posture. Moreover, when the piston rod is squeezed, the bottom end of the piston rod and the limiting rod fall to the bottom end of the limiting flow channel, which can support the container and prevent the two containers from tilting to the middle during the opening process, thereby avoiding imbalance of the container.

DETAILED DESCRIPTION

[0043] 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. However, the embodiments described below are only some embodiments of the present invention, not all of them. If other embodiments of ordinary technicians in this field are obtained without making creative work, they all belong to the protection scope of the present invention.

[0044] Reference Figure 1 , Figure 2 and Figure 4A material conveying system for food processing includes a mounting plate 1, a servo motor 2 and a rotating roller 3, and also includes a support plate 4, an opening machine 5, a conveyor belt 6, a driving mechanism 7, a container 8, a transmission mechanism 9 and a clamp 10. The support plate 4 is installed at one end of the mounting plate 1. Through the setting of the support plate 4, the conveyor belt 6 can be supported so that the conveyor belt 6 can rotate in contact with the support plate 4, and the conveyor belt 6 can be stressed and supported when the chestnuts are opened. The opening machine 5 is installed at the top of the mounting plate 1, and the conveyor belt 6 is arranged in contact with the support plate 4 and the rotating roller 3. The driving mechanism 7 is connected to the support plate 4 and the conveyor belt 6. The container 8 is connected to the driving mechanism 7. Through the setting of the conveyor belt 6, the container 8 can be driven by the driving mechanism 7 to move forward. The driving mechanism 7 can drive the chestnuts forward and can drive the two containers 8 to move toward each other, thereby reducing the distance between the two containers 8. By reducing the placement space of the chestnuts, it can ensure that the chestnuts are as close to the middle area of ​​the container 8 as possible. The container 8 can be placed by the setting of the container 8. The container 8 is bowl-shaped, and a material trough 12 is provided inside the container 8. The material trough 12 is fan-shaped. The above setting is to correspond to the container 8 when the curved surface of the chestnut faces downward, thereby avoiding the possibility of the chestnut being in an unstable posture. The sum of the radius value of the material trough 12 in the two containers 8 and the spacing value of the two conveyor belts 6 is equal to the diameter value of the material trough 12. The above setting is to keep one end of the two containers 8 level with one end of the conveyor belt 6. When the two material troughs 12 are aligned, a semicircular shape is formed between them. At this time, the material trough 12 has the largest space for placing chestnuts, so that the chestnuts can be placed better. The transmission mechanism 9 is connected to the container 8, and the clamping piece 10 is connected to the transmission mechanism 9. Through the setting of the transmission mechanism 9, the clamping piece 10 can be driven to move synchronously when the container 8 moves, and the size of the material trough 12 can be further reduced, so that the chestnuts can be located in the central area of ​​the material trough 12 as much as possible. The clamping piece 10 is arranged in an arc shape. Through the above arrangement, it is to achieve that the chestnuts can be clamped by the clamping piece 10 regardless of whether the arc surface is facing up or down. The clamping piece 10 is installed on the inner wall of the material trough 12. The clamping piece 10 is elastic and can be deformed when squeezed by the transmission mechanism 9. At the same time, it can be reset after losing the pressure of the transmission mechanism 9. Two groups of inclined blocks 11 are evenly arranged on one side of the clamping piece 10, and one end of each group of inclined blocks 11 is arc-shaped. The two groups of inclined blocks 11 are inclined upward, and one end of each group of inclined blocks 11 is connected by a curve. The curvature of the clamping piece 10 is greater than the curvature of the end of the inclined block 11. Through the above arrangement, pressure can be applied to the chestnut when the clamping piece 10 clamps the chestnut, and at the same time, an oblique upward component force will be generated under the action of the inclined block 11. Under the action of pressure, the chestnut will be squeezed toward the middle and the middle area of ​​the chestnut will be pressed to arch, so that the chestnut shell and the flesh can be separated, thereby avoiding damage to the flesh when opening. When the servo motor 2 drives the rotating roller 3 to rotate, the conveyor belt 6 drives the container 8 to move cyclically toward the direction of the opening machine 5, and controls the two containers 8 to move toward each other to clamp the chestnut through the driving mechanism 7.When the two containers 8 move toward each other, the transmission mechanism 9 controls the clamping piece 10 to press the chestnuts and make the chestnuts arch upward.

[0045] As an embodiment of the present invention, refer to Figures 3 to 5 and Figure 7 The driving mechanism 7 includes a transverse rack 71, a spur gear 72, a forward and reverse reciprocating screw rod 73, a moving block 74, a mounting seat 75 and a shaking unit 76. The transverse rack 71 is mounted on the top of the support plate 4. The teeth on the transverse rack 71 are symmetrically arranged, and the teeth are respectively located on one side of the feeding end and the discharging end of the opening machine 5. The teeth at the feeding end of the opening machine 5 are locking teeth, while the teeth at the discharging end of the opening machine 5 are loose teeth. When the container 8 moves with the chestnuts to the feeding end of the opening machine 5, the chestnuts can be clamped. When the chestnuts are opened, the container 8 can be controlled to loosen the chestnuts, which is convenient The spur gear 72 cooperates with the transverse rack 71 for feeding chestnuts. Through the setting of the transverse rack 71, the spur gear 72 can be driven to move synchronously during the rotation of the conveyor belt 6, and mesh with the transverse rack 71 to drive the spur gear 72 to rotate. The forward and reverse reciprocating screw rod 73 is connected to the spur gear 72. The rotation of the spur gear 72 can drive the rotation of the forward and reverse reciprocating screw rod 73. The rotation of the forward and reverse reciprocating screw rod 73 can drive the two moving blocks 74 to move toward or in the opposite direction. The length of the thread on the forward and reverse reciprocating screw rod 73, the circumference of the spur gear 72, and the tooth length of the tooth The length values ​​are consistent. Through the above arrangement, the horizontal movement distance of the moving block 74 can be kept consistent with the rotation distance of the spur gear 72, so that the synchronization of movement can be achieved. The moving block 74 is connected to the forward and reverse reciprocating screw rod 73, and the container 8 is installed on the top of the moving block 74. When the two moving blocks 74 move towards each other, they can synchronously drive the container 8 to move. The mounting seat 75 is respectively connected to the forward and reverse reciprocating screw rod 73 and the moving block 74. Through the arrangement of the mounting seat 75, the conveyor belt 6 can be connected with the cross rack 71, the spur gear 72, the forward and reverse reciprocating screw rod 73, the moving block 7 4 is connected, and the transverse rack 71, the spur gear 72, the forward and reverse reciprocating screw rod 73, and the moving block 74 are installed through the mounting seat 75 to provide a base for the operation of the transverse rack 71, the spur gear 72, the forward and reverse reciprocating screw rod 73, and the moving block 74. The conveyor belt 6, the container 8, the moving block 74 and the mounting seat 75 are all symmetrically arranged with the transverse rack 71 as the center. The spacing value of the two conveyor belts 6 is greater than the width value of the transverse rack 71 and the spur gear 72. Through the above arrangement, it is possible to prevent the operation of the conveyor belt 6 from hindering the operation of the transverse rack 71 and the spur gear 72.

[0046] As an embodiment of the present invention, refer to Figure 4 and Figure 5, the shaking unit 76 includes a transverse plate 761, a limiting flow channel 762, a limiting rod 763, a piston rod 764, a sleeve 765 and a spring 766, the transverse plate 761 is installed on the top of the mounting seat 75, the limiting flow channel 762 is opened inside the transverse plate 761, the limiting flow channel 762 includes a guide portion 7621 and an impact portion 7622, ​​the guide portion 7621 is connected to the adjacent impact portion 7622, ​​and the movement of the limiting rod 763 can be guided by arranging the guide portion 7621 and the impact portion 7622 in the limiting flow channel 762, the curvature of the guide portion 7621 is smaller than the curvature of the impact portion 7622, ​​and the connection between the guide portion 7621 and the impact portion 7622 is set to an arc shape. The above arrangement is to allow the limiting rod 763 to generate a speed difference when moving. When the limiting rod 763 moves on the guide portion 7621, the speed is uniform and slow. When bypassing the guide portion When 7621 reaches the impact portion 7622, ​​the limit rod 763 will move quickly on the impact portion 7622 under the action of the tension of the spring 766, so as to control the piston rod 764 to move quickly and impact the container 8. The limit rod 763 cooperates with the limit channel 762, and the piston rod 764 is connected to the limit rod 763. By controlling the limit rod 763 to move with a differential speed in the limit channel 762, the piston rod 764 can be pulled. The sleeve 765 is connected to the piston rod 764, and the sleeve 765 is installed at the bottom end of the container 8. A chamber 767 is opened inside the sleeve 765, and the spring 766 is installed between the piston rod 764 and the chamber 767. Through the above arrangement, space can be provided for the movement of the piston rod 764, and at the same time, the stretching or rebound of the piston rod 764 can be achieved when the limit rod 763 moves in the limit channel 762.

[0047] As an embodiment of the present invention, refer to Figure 6 and Figure 7The transmission mechanism 9 includes a longitudinal rack 91, a driving gear 92, a driving rod 93, a connecting rod 94 and a rotating disk 95. The longitudinal rack 91 is installed at the top of the mounting seat 75, and the driving gear 92 cooperates with the longitudinal rack 91. The longitudinal rack 91 and the transverse rack 71 are vertically arranged at 90 degrees. This arrangement is to keep consistent with the movement path of the conveyor belt 6 and the container 8. When the container 8 moves toward each other, it can drive the driving gear 92 to move and then mesh with the longitudinal rack 91. The driving rod 93 is respectively installed on one side of the driving gear 92 and the rotating disk 95, and the connecting rod 94 is installed between the two driving rods 93. The two driving rods 93 are symmetrically arranged about the center line of the connecting rod 94. Through the above arrangement, a structure similar to a crank slider is formed. When the driving gear 92 rotates, the two driving rods 93 cooperate with the connecting rod 94 to drive the rotating disk 95 to rotate synchronously, and the two driving rods 93 respectively perform eccentric movement around the driving gear 92 and the rotating disk 95. The inner wall of the container 8 is provided with a moving Slot 96, driving rod 93, connecting rod 94 and rotating disk 95 are all matched with the motion slot 96. Through the setting of the motion slot 96, the driving rod 93, connecting rod 94 and rotating disk 95 can provide movement space. A rotating shaft 97 is arranged between the driving rod 93 and the driving gear 92 and the rotating disk 95. The rotating shaft 97 is located at 1 / 3-1 / 2 of the diameter of the driving gear 92 and the rotating disk 95. Through the above arrangement, the eccentric rotation amplitude of the driving rod 93 can be controlled, so that the eccentric value of the rotating disk 95 can be set to achieve the control of the movement amplitude of the clamp 10. The length value of the horizontal plate 761 is greater than the length value of the longitudinal rack 91. This arrangement is to increase the time for the chestnut to adjust its posture and indirectly shorten the time for clamping the chestnut, so as to avoid applying greater pressure on the chestnut and avoid damage to the chestnut. A crescent-shaped protrusion 98 is installed on the rotating disk 95. Through the above arrangement, the protrusion 98 can be controlled to contact with the clamp 10 when the rotating disk 95 rotates, so that the clamp 10 can be pushed.

[0048] Working principle: the user places the chestnuts in the container 8 in sequence, and then controls the conveyor belt 6 to rotate through the servo motor 2. When the conveyor belt 6 rotates, it drives the container 8 with chestnuts to move synchronously through the driving mechanism 7, and drives the two containers 8 to move towards each other when passing through the horizontal rack 71, so as to reduce the storage space of the chestnuts, and shakes the chestnuts in the container 8 through the shaking unit 76 to adjust the posture of the chestnuts. At the same time, the transmission mechanism 9 controls the clamping piece 10 to clamp the chestnuts, so that the chestnuts can be placed in the center of the container 8, and the center of the chestnuts can be opened when opening;

[0049] Specifically, the user starts the servo motor 2, and the servo motor 2 drives the rotating roller 3 to rotate when it starts. Since the rotating roller 3 is in contact with the conveyor belt 6, the conveyor belt 6 can be driven to rotate. Since the mounting seat 75 is installed on the conveyor belt 6, the conveyor belt 6 can drive the mounting seat 75 to rotate synchronously when it rotates. When the mounting seat 75 rotates, it can drive the spur gear 72 to mesh with the horizontal rack 71, thereby driving the spur gear 72 to rotate. When the spur gear 72 rotates, it can drive the forward and reverse reciprocating screw rod 73 to rotate, thereby driving the two moving blocks 74 to move toward each other. When the moving block 74 moves, it can drive the container 8 to move synchronously. When the two containers 8 gradually approach each other, the placement space of the chestnuts in the trough 12 will gradually decrease.

[0050] When the container 8 moves, the sleeve 765 is driven to move synchronously. Since the piston rod 764 is installed in the sleeve 765, the piston rod will move synchronously with the sleeve 765. Since the limit rod 763 is installed at the bottom end of the piston rod, and the limit rod 763 is installed in the limit flow channel 762 in the cross plate 761, the limit rod 763 will move in the limit flow channel 762 with the piston rod. The limit rod 763 is in alternating contact with the guide portion 7621 and the impact portion 7622. When the limit rod 763 moves on the guide portion 7621, the limit rod 763 is in a slow oblique downward movement, and at the same time, it will drive the piston rod downward. When the limit rod 763 moves from the guide portion 7621 to the impact portion 7622, ​​the limit rod 763 moves obliquely upward along the guide portion 7621, and at the same time pushes the piston rod 764 to move obliquely upward, and the spring 766 will rebound to accelerate the rise of the piston rod. When the limit rod 763 moves on the guide portion 7621 and the impact portion 7622, ​​a drop will be generated, so that the piston rod will impact the container 8 when it rises rapidly. The impact will cause the container 8 to shake, and the shaking will be indirectly transmitted to the chestnut. Under the action of the shaking, the chestnut will adjust its posture;

[0051] When the two containers 8 move toward each other, they will drive the driving gear 92 to move synchronously. When the driving gear 92 contacts the longitudinal rack 91, they will mesh, thereby driving the driving gear 92 to rotate. When the driving gear 92 rotates, it can drive the driving rod 93 to perform eccentric movement around the driving gear 92 under the action of the rotating shaft 97. When the driving rod 93 performs eccentric movement, it can pull and push the connecting rod 94 reciprocatingly. When the connecting rod 94 switches between pulling and pushing, it can drive the driving rod 93 at the top of the connecting rod 94 to move, and rotate around the rotating disk 95 under the action of the rotating shaft 97. When the rotating disk 95 rotates The protrusion 98 can be driven to rotate. When the protrusion 98 rotates to contact the clamping piece 10, the clamping piece 10 can be squeezed as the rotating disk 95 rotates, so that the clamping piece 10 can be controlled to clamp the chestnut, and the fit degree is improved under the action of the inclined block 11. As the rotating disk 95 and the protrusion 98 continue to rotate, the contact point between the protrusion 98 and the clamping piece 10 gradually moves toward the end, so that pressure can be applied to the chestnut. Under the action of pressure, the inclined block 11 can be controlled to apply an oblique upward force to the chestnut, and then the chestnut is clamped in the middle area of ​​the container 8, and the area to be opened in the middle of the chestnut is squeezed to be arched, so that the chestnut shell and the flesh are separated;

[0052] With the continuous rotation of the conveyor belt 6, the clamped chestnuts can be conveyed to the bottom of the opening machine 5. When the opening machine 5 is aligned with the chestnuts, the opening machine 5 opens the chestnuts. After the opening is completed, the conveyor belt 6 drives the opened chestnuts to continue moving forward, and then controls the spur gear 72 and the cross rack 71 to engage again. This contact will control the two moving blocks 74 to move in the opposite direction while the forward and reverse reciprocating screw rod 73 rotates, thereby controlling the above-mentioned device to move in the opposite direction, thereby loosening the chestnuts, and then facilitating the unloading of the opened chestnuts.
