Description

Technical Field

[0001] The present invention relates to the technical field of mushroom cultivation, and particularly relates to a mushroom stick processing device. Background Art

[0002] In recent years, the edible mushroom industry in China has developed rapidly, and the usage of mushroom sticks has increased year by year. During the production process of mushroom sticks, to ensure the stability of the culture medium, prevent contamination by miscellaneous bacteria, and facilitate transportation, plastic films are usually wrapped around the outside of the mushroom sticks, and blocking ropes are used for bundling and fixing. These auxiliary materials play an important role in the cultivation stage of the mushroom sticks, but in the processing link after the mushroom sticks complete the production of edible mushrooms, they have become the key factors hindering efficient processing. When the mushroom sticks are recycled, the first step is usually crushing. However, direct crushing will cause the plastic films and blocking ropes to entangle and adhere to the mushroom stick materials, resulting in a large number of microplastic fragments in the primary product. This greatly affects the subsequent processing efficiency and quality while posing a potential risk of microplastic pollution.

[0003] Currently, in the field of mushroom stick processing, there are many deficiencies in the existing technologies for removing the plastic films and blocking ropes on the surface of the mushroom sticks. Some technologies adopt the method of manual sorting. Before crushing, the operator manually tears the plastic film and unties the rope. Although this method can remove impurities more carefully, the efficiency is extremely low and it is difficult to meet the requirements of large-scale mushroom stick processing. Moreover, long-term manual operation is likely to cause operator fatigue, resulting in incomplete sorting and allowing some impurities to enter the subsequent crushing process.

[0004] There are also some technologies that adopt the strategy of screening and separating after crushing. However, this method has serious defects. Direct crushing causes the plastic films and blocking ropes to be tightly wound around the mushroom stick fragments, making it extremely difficult to screen and separate them subsequently. Whether it is screening by the aperture of the sieve mesh or separating by physical properties such as magnetism and static electricity, it is difficult to completely separate the entangled impurities, resulting in serious residue of impurities such as microplastics in the final processed product, affecting the quality and value of the resource utilization of the mushroom sticks.

[0005] In summary, the existing mushroom stick processing technologies have problems such as low processing efficiency, incomplete separation, and easy blockage of equipment when dealing with impurities of plastic films and blocking ropes, whether it is the removal before crushing or the separation after crushing. Summary of the Invention

[0006] The present invention aims to provide a mushroom stick processing device to solve the problems of low efficiency in traditional manual processing of mushroom sticks, poor purity of the culture medium due to film residue and rope entanglement.

[0007] A mushroom stick processing device in this solution includes a base, a screen is provided on the base, an arc-shaped pressing plate and a pressing mechanism are provided on the base, and the screen is located between the pressing plate and the pressing mechanism; the pressing mechanism includes a rotating cylinder, and the rotating cylinder is rotatably connected to a driver that drives it to reciprocate horizontally and rotate self - sufficiently. The rotating cylinder faces the arc - shaped pressing plate, and hook - shaped spikes for hooking plastic films and ropes are evenly distributed on the rotating cylinder.

[0008] The working principle and its beneficial effects of this solution: During use, the operator first neatly arranges the mushroom sticks at a position on the base close to the pressing plate, so that the mushroom sticks are in the working area between the pressing plate and the rotating cylinder. Start the driver, and drive the rotating cylinder to perform a reciprocating movement horizontally on the base, and at the same time, the rotating cylinder rotates self - sufficiently.

[0009] During the process of the rotating cylinder moving towards the pressing plate, the hook - shaped spikes evenly distributed on its surface first contact the plastic film and rope on the outer surface of the mushroom stick. As the rotating cylinder continues to approach the pressing plate, the hook - shaped spikes pierce the plastic film with their sharp structure and firmly hook the film with their hook - shaped appearance. At the same time, the squeezing force formed by the rotating cylinder and the pressing plate on the mushroom stick gradually increases. When the pressure reaches the critical point, the mushroom stick is squeezed and broken, and the internal culture medium scatters. If there is a rope for bundling the mushroom stick, the hook - shaped spikes will also embed into the rope gap and firmly hook it.

[0010] When the rotating cylinder completes a squeezing action of approaching the pressing plate, the driver drives the rotating cylinder to gradually move away from the pressing plate. During the backward movement of the rotating cylinder, the hook - shaped spikes continue to rotate, strip the hooked plastic film and rope from the broken mushroom stick, and drive them away from the area where the pressing plate is located. The plastic film and the blocking rope stay on the hook - shaped spikes, thus completing a complete separation process. At this time, the operator can quickly replenish new mushroom sticks to the working area, and the rotating cylinder then repeats the above - mentioned cycle process of squeezing and breaking, hooking and separating, to achieve continuous operation. When the hook - shaped spikes are covered with films and ropes, the driver can be stopped, and the films and ropes are removed from the hook - shaped spikes. The pressed mushroom stick body falls from the screen.

[0011] The combination of the reciprocating horizontal movement and self - rotation of the rotating cylinder realizes the continuous squeezing and breaking of the mushroom stick and the synchronous separation of the film and the rope. Compared with the traditional manual processing method, it greatly improves the processing efficiency of the mushroom stick, shortens the processing time, and meets the needs of large - scale production. The hook - shaped spikes are evenly distributed and have a sharp structure, which can fully pierce the plastic film and hook the rope, effectively avoiding film residue and rope entanglement, ensuring the purity of the culture medium after the mushroom stick is broken. While separating the plastic film and the blocking rope on the mushroom stick, it will not affect the gradual addition of new mushroom sticks to be processed. In the processing of the mushroom stick, through the gradually increasing squeezing force and the self - rotation of the rotating cylinder, the rapid breaking of the mushroom stick is realized, and at the same time, the hook - shaped spikes rotate with the rotating cylinder to take away the plastic film and the blocking rope.

[0012] Furthermore, the driver includes a telescopic member, a driving pulley, a transmission pulley, and a driven pulley. The driving pulley is connected to the transmission pulley by a belt, and the transmission pulley is connected to the driven pulley by a belt. Connecting rods are rotatably connected between the driving pulley and the transmission pulley, and between the transmission pulley and the driven pulley. The driving pulley is connected to a rotating rod, the rotating rod is connected to a motor that drives its rotation, a cam is fixedly connected to the rotating rod, and the driven pulley is fixedly connected to the rotating cylinder; the telescopic member includes a fixed frame and a telescopic frame that is horizontally slidably connected to the fixed frame. The rotating cylinder is rotatably connected to the telescopic frame, the rotating rod is rotatably connected to the fixed frame, the cam abuts against the telescopic frame, and a restoring member is also provided for automatically restoring the rotating cylinder. After starting the motor, the motor drives the rotating rod to synchronously drive the driving pulley and the cam to rotate. The driving pulley drives the transmission pulley and the driven pulley in sequence through belt transmission, and finally drives the rotating cylinder to achieve self-rotation; at the same time, the rotating contour of the cam periodically abuts against the telescopic frame. With the cooperation of the restoring member, the telescopic frame is forced to perform reciprocating linear motion in the horizontal direction, thereby driving the rotating cylinder to synchronously achieve horizontal displacement. Through the design of converting rotational motion into linear motion, decoupled control of the self-rotation and horizontal movement of the rotating cylinder is achieved, ensuring that the peeling effect between the film and the rope during the extrusion process is not affected.

[0013] Furthermore, the restoring member is a restoring spring, and the restoring spring is fixedly connected between the telescopic frame and the fixed frame. The setting of the restoring spring facilitates the restoration of the telescopic frame.

[0014] Furthermore, a roller is rotatably connected to the telescopic frame, and the cam abuts against the roller. When the cam and the telescopic frame move relative to each other, if they are in direct contact, a large sliding friction will be generated. The presence of the roller converts the sliding friction into rolling friction. The roller is rotatably connected to the telescopic frame and abuts against the cam, converting the sliding friction between the cam and the telescopic frame into rolling friction, greatly reducing the friction loss and component wear, while making the force transmission smoother, avoiding jamming and jitter when the telescopic frame moves, and ensuring the stability of the movement of the rotating cylinder and the operation of the device.

[0015] Furthermore, a support rod is provided on the base, and a spiral arc-shaped rod is connected to the support rod. Barbs are provided on the side of the arc-shaped rod facing the rotating cylinder, and the barbs are staggered with hook-shaped spikes. During the movement of the rotating cylinder away from the extrusion plate along with the telescopic frame, when passing through the inclined arc-shaped rod, the barbs on the arc-shaped rod and the hook-shaped spikes on the surface of the rotating cylinder form an interleaved meshing state in space. By virtue of the reverse hook structure of the barbs and the mechanical antagonism formed by the hook-shaped spikes, the plastic film and the rope wound around the hook-shaped spikes can be forcibly peeled off, realizing the efficient separation of materials.

[0016] Furthermore, the hooked spikes include spines inclined in the direction of the rotating cylinder and arc-shaped hooked spines. The inclined spines utilize the rotational inertia of the rotating cylinder to reduce the hooking resistance between the film and the rope, and cooperate with the rear arc-shaped hooked spines to form a mechanical structure of "front hook and rear lock". When the material is lifted by the spines, it is immediately firmly restricted within the gap between the two by the concave curved surface of the arc-shaped hooked spines, effectively preventing the material from slipping or detaching during the movement of the rotating cylinder and ensuring the stability and integrity of the peeling process.

[0023] Embodiment 1

[0024] Basically as shown in the attached Figures 1 to 3As shown: A mushroom stick processing device includes a base 1. There are holes on the base 1, and a screen 18 is arranged in the holes. An arc-shaped pressing plate 2 and a pressing mechanism are arranged on the base 1. The screen 18 is located between the pressing plate 2 and the pressing mechanism; the pressing mechanism includes a rotating cylinder 10. The screen 18 is located between the rotating cylinder 10 and the pressing plate 2. The rotating cylinder 10 is rotatably connected to a driver that drives it to reciprocate horizontally and rotate. The driver includes a telescopic member, a driving pulley 14, a transmission pulley 15, and a driven pulley 16. The driving pulley 14 and the transmission pulley 15, and the transmission pulley 15 and the driven pulley 16 are connected by a belt 13. Connecting rods 17 are rotatably connected between the driving pulley 14 and the transmission pulley 15, and between the transmission pulley 15 and the driven pulley 16. The driving pulley 14 is connected to a rotating rod 7. The rotating rod 7 is connected to a motor that drives it to rotate. A cam 8 is fixedly connected to the rotating rod 7. The driven pulley 16 is fixedly connected to the rotating cylinder 10; the telescopic member includes a fixed frame 3. A limiting rod 31 is arranged on the fixed frame 3. A telescopic frame 12 is horizontally slidably connected to the fixed frame 3. The telescopic frame 12 is fixedly connected to the fixed frame 3 through the limiting rod 31. The fixed frame 3 is fixedly connected to the base 1. The rotating cylinder 10 is rotatably connected to the telescopic frame 12. The rotating rod 7 is rotatably connected to the fixed frame. The cam 8 abuts against the telescopic frame 12. A return member for automatically returning the rotating cylinder 10 is also provided. The return member is a return spring 4. The return spring 4 is fixedly connected between the telescopic frame 12 and the fixed frame 3. A roller 9 is rotatably connected to the telescopic frame 12. The cam 8 abuts against the roller 9;

[0025] The rotating cylinder 10 faces the arc-shaped pressing plate 2. Hook-shaped spines 11 for hooking plastic films and ropes are evenly distributed on the rotating cylinder 10. The distance between each hook-shaped spine 11 is 7 cm. The hook-shaped spine 11 includes a protruding spine 111 inclined towards the rotating direction of the rotating cylinder 10 and an arc-shaped hook spine 112. The inclination angle of the protruding spine 111 is set to 30°;

[0026] A support rod 5 is arranged on the base 1. A spiral arc-shaped rod 6 is connected to the support rod 5. Barbs 61 are arranged on the side of the arc-shaped rod 6 facing the rotating cylinder 10. The barbs 61 are staggered with the hook-shaped spines 11.

[0027] The operator neatly places the mushroom sticks on the base 1 near the pressing plate 2, so that the mushroom sticks are in the working area between the pressing plate 2 and the rotating cylinder 10. Start the motor, the motor drives the rotating rod 7 to rotate, and the rotating rod 7 drives the driving pulley 14 and the cam 8 to rotate. The driving pulley 14 is driven by the belt 13 to drive the driven pulley 15 and the driven pulley 16 in sequence, and finally drives the rotating cylinder 10 to rotate; at the same time, the rotating contour of the cam 8 periodically abuts against the telescopic frame 12, and under the cooperation of the return spring 4 (return member), forces the telescopic frame 12 to perform a reciprocating linear motion in the horizontal direction, thereby driving the rotating cylinder 10 to synchronously achieve a horizontal displacement. During this process, the roller 9 on the telescopic frame 12 abuts against the cam 8, converting sliding friction into rolling friction, reducing friction loss and component wear, making the force transmission smoother, and ensuring the stability of the movement of the rotating cylinder 10 and the operation of the device.

[0028] During the process of the rotating cylinder 10 moving towards the pressing plate 2, the hook-shaped spikes 11 evenly distributed on the surface of the rotating cylinder 10 (composed of protruding spikes 111 inclined in the rotating direction of the rotating cylinder 10 and arc-shaped hook spikes 112) first contact the plastic film and rope on the outer surface of the mushroom stick. The protruding spike 111 utilizes the rotational inertia of the rotating cylinder 10 to reduce the hooking resistance, and the arc-shaped hook spike 112 firmly restricts the material. As the rotating cylinder 10 continues to approach the pressing plate 2, the hook-shaped spikes 11 pierce the plastic film and hook the film, and the pressing force of the rotating cylinder 10 and the pressing plate 2 on the mushroom stick gradually increases (the used mushroom sticks, after being collected, the moisture evaporates and dries up, becoming brittle, and can be crushed by pinching with fingers). When the pressure reaches the critical point, the mushroom stick is crushed by extrusion, and the internal culture medium scatters. If there is a rope for bundling the mushroom stick, the hook-shaped spikes 11 will also be embedded in the rope gap and hook it.

[0029] After the rotating cylinder 10 completes a pressing action close to the pressing plate 2, the driver drives the rotating cylinder 10 to gradually move away from the pressing plate 2. During the backward movement of the rotating cylinder 10, the hook-shaped spikes 11 continue to rotate, peeling off the hooked plastic film and rope from the crushed mushroom stick, and driving them away from the area where the pressing plate 2 is located. The plastic film and rope stay on the hook-shaped spikes 11. During the movement of the rotating cylinder 10 away from the pressing plate 2 along with the telescopic frame 12, when passing through the inclined spiral-shaped arc-shaped rod 6 connected to the support rod 5 on the base 1, the barbs 61 on the arc-shaped rod 6 are engaged with the hook-shaped spikes 11 on the surface of the rotating cylinder 10 in a staggered manner. The barbs 61, relying on the reverse hooking structure, forcibly peel off the plastic film and rope wound around the hook-shaped spikes 11, realizing efficient separation of the material.

[0030] After completing a complete separation process, the operator can quickly replenish new mushroom sticks to the working area, and the rotating cylinder 10 then repeats the above cycle process of extrusion and crushing, hooking and separation to achieve continuous operation. When the hook-shaped spikes 11 are covered with film and rope, stop the driver, remove the film and rope from the hook-shaped spikes 11, and the pressed mushroom stick body falls from the sieve 18.

[0031] Example 2

[0032] As Figure 4 shown, the difference from Example 1 is that an elevation platform 19 is placed on the base 1, and the elevation platform 19 is close to the extrusion plate 2. In this way, the elevation platform 19 can play a role in raising the position of the mushroom stick to be extruded, so that the whole mushroom stick can be extruded. And a sieve mesh 18 is also arranged on the elevation platform 19 accordingly, so that the crushed mushroom stick can fall from the sieve mesh 18.

It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several modifications can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
