Description

Technical Field

[0001] This utility model is an arch-breaking device for a silo, belonging to the field of food waste treatment. Background Technology

[0002] In the pretreatment process of food waste, a double-roller crushing structure at the bottom of the hopper is often used to reduce the volume of the waste. Two cooperating rollers are installed parallel to each other at the bottom of the hopper. One roller is driven by a motor and, through a transmission structure, can drive the other roller to rotate synchronously in opposite directions. During operation, food waste is put into the hopper and falls to the roller area under gravity. Through the interlocking and shearing action of the two rollers, large pieces of waste (such as leftover food, fruit peels, bone fragments, etc.) are crushed into fine particles, laying the foundation for subsequent fermentation, landfill, or resource recycling, and significantly improving the processing efficiency of subsequent processes.

[0003] The large amount of grease in food waste easily solidifies at low temperatures, or due to the interlocking of fibers and lumpy impurities, it can easily form a "bridging" phenomenon inside the hopper. This means that waste particles support each other in the middle or upper part of the hopper, forming a stable arched structure, creating voids in the lower cutter roller area, preventing the waste from falling normally and interrupting the crushing operation. To solve this problem, the industry commonly uses a "stick-tapping" method to break the arch: operators hold a long, rod-like stick and insert it into the top opening of the hopper, repeatedly tamping and poking the bridged waste layer to disrupt the stability of the arched structure, causing the waste to fall back into the cutter roller area. However, this manual arch-breaking method has significant safety risks and equipment damage hazards: because the internal space of the hopper is relatively enclosed, and the cutter roller is constantly rotating driven by a motor, it is difficult for operators to accurately determine the exact position of the stick end inside the hopper when tamping from the outside. When the bridging position is close to the bottom cutter roller of the hopper, the end of the roller is very likely to accidentally touch the high-speed rotating cutter roller during the tamping process. The sharp teeth of the cutter roller will not only wear down the end of the roller instantly, causing the roller to be damaged and unusable, but the rotation of the cutter roller may also cause the roller to shake, resulting in hand injury to the operator. If the roller is caught in the cutter roller, it may also cause equipment failures such as cutter roller jamming and motor overload, further increasing production losses and interrupting the crushing and processing of kitchen waste. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an arch-breaking device for silos to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silo arch-breaking device, comprising:

[0006] The cargo box has a structure that is wider at the top and narrower at the bottom;

[0007] A movable plate slides in contact with an inner wall of the silo. A top plate is installed on the upper part of the movable plate. A hydraulic cylinder is installed on one side of the silo. The movable end of the hydraulic cylinder keeps its relative position to the top plate unchanged. A pressure plate is hinged to the upper part of one side of the movable plate. A screw is threaded to the upper surface of the top plate away from the hydraulic cylinder to limit the maximum angle of expansion between the pressure plate and the movable plate.

[0008] Furthermore, a straight cylinder is installed on the upper surface of the top plate away from the hydraulic cylinder. A circular nut is installed in the middle of the straight cylinder. The screw is threadedly connected to the circular nut. Both ends of the screw extend to the outside of the straight cylinder. Rubber plugs are provided on the upper and lower sides of the circular nut. The rubber plugs are slidably installed inside the straight cylinder. The rubber plugs are sleeved on the screw and keep their relative position to the screw unchanged. The distance between the two rubber plugs is half the height of the straight cylinder.

[0009] Furthermore, a knob head is provided on the upper side of the screw, and a blind hole is formed by a recess in the middle of the lower surface of the knob head, and the upper end of the screw is installed in the blind hole.

[0010] Furthermore, a vertical hole is provided on the upper surface of the top plate away from the hydraulic cylinder, and the lower end of the straight cylinder is installed in the vertical hole.

[0011] Furthermore, the cylinder body end of the hydraulic cylinder is connected to a support by screws, and the support is fixedly connected to the chamber body.

[0012] Furthermore, two cooperating cutter rollers are rotatably installed in the lower part of the chamber. One end of one cutter roller extends to the outside of the chamber and is equipped with a driven pulley. A motor is provided on one side of the chamber, and a drive pulley is installed on the output shaft of the motor. The drive pulley is connected to the driven pulley through a transmission belt.

[0013] Furthermore, a frame is provided on the lower side of the hopper body. The frame is a rectangular structure, and support legs are installed at the four corners of the frame. An intermediate frame is installed in the middle of the frame. The lower end of the hopper body and the motor are connected to the intermediate frame by bolts.

[0014] Furthermore, a horizontal strip is hinged to the upper end of the pressure plate, and the horizontal strip is connected and fixed to the movable plate.

[0015] The beneficial effects of this utility model are:

[0016] A hydraulic cylinder drives a movable plate to slide up and down along the inner wall of the silo. The pressure plate moves synchronously with the movable plate, applying pressure to the bridging food waste inside the silo and breaking the arched structure. The entire process does not require operators to insert the rods, completely avoiding the problem of rods coming into contact with the cutter rollers due to obstructed vision and misjudgment of position during manual stirring. This prevents the sharp teeth of the cutter rollers from wearing down tools, preventing rods from getting caught and causing equipment jamming or motor overload, and also eliminates the risk of hand injuries caused by the swaying of the rods, thus improving the safety of the food waste treatment process and the stability of equipment operation.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] Please see Figures 1-3 This utility model provides a technical solution: a silo arch-breaking device, including a silo body 1, which has a structure that is wider at the top and narrower at the bottom. Two cooperating cutter rollers 24 are rotatably installed in the lower part of the silo body 1. One end of one cutter roller 24 extends to the outside of the silo body 1 and is equipped with a driven pulley 23. A motor 2 is provided on one side of the silo body 1. A drive pulley 21 is installed on the output shaft of the motor 2. The drive pulley 21 is connected to the driven pulley 23 through a transmission belt 22. When the motor 2 is working, it drives the two cutter rollers 24 to rotate in opposite directions through the transmission belt 22, thereby crushing the kitchen waste. A frame 4 is provided on the lower side of the silo body 1. The frame 4 has a rectangular structure. Support legs 41 are installed at the four corners of the frame 4. A middle frame 42 is installed in the middle of the frame 4. The lower end of the silo body 1 and the motor 2 are connected to the middle frame 42 by bolts. The structure formed by the frame 4, the support legs 41 and the middle frame 42 provides support for the silo body 1 and the motor 2.

[0031] See Figures 1-5 The movable plate 3 slides in contact with the inner wall of the silo 1. A top plate 31 is installed on the upper end of the movable plate 3. A hydraulic cylinder 33 is installed on one side of the silo 1. The movable end of the hydraulic cylinder 33 and the top plate 31 remain in a fixed relative position. The cylinder end of the hydraulic cylinder 33 is connected to a support 34 by screws. The support 34 is fixed to the silo 1 and serves to connect the hydraulic cylinder 33 and the silo 1. A pressure plate 32 is hinged to the upper part of one side of the movable plate 3. A horizontal strip 35 is hinged to the upper end of the pressure plate 32 and is fixed to the movable plate 3. The horizontal strip 35 serves to connect the pressure plate 32 and the movable plate 3. Through the mechanical linkage structure of "hydraulic cylinder 33-movable plate 3-pressure plate 32", the traditional manual method of "ploughing with sticks" is completely replaced. The hydraulic cylinder 33 drives the movable plate 3 to slide up and down along the inner wall of the silo 1. The pressure plate 32 moves synchronously with the movable plate 3 and applies pressure to the bridging kitchen waste in the silo 1, thus destroying the arch structure. The entire process does not require operators to insert the rod, completely avoiding the problem of the rod coming into contact with the cutter roller 24 due to obstructed vision and misjudgment of position during manual stirring. It prevents the sharp teeth of the cutter roller 24 from wearing down tools, getting the rod caught and causing equipment jamming or motor 2 overload, and eliminates the risk of hand injury caused by the shaking of the rod, thus improving the safety of the food waste treatment process and the stability of equipment operation.

[0032] The arch-breaking action of the movable plate 3 and the pressure plate 32 is concentrated in the upper part of the bin 1, and a safe distance has been reserved between them and the bottom cutter roller 24 of the bin 1. The movable plate 3 and the pressure plate 32 will not extend downward into the working area of ​​the cutter roller 24. This structural layout spatially isolates the movable plate 3 and the pressure plate 32 from contact with the cutter roller 24. Even when dealing with slight bridging near the bottom, the controllable pressure of the pressure plate 32 can gradually guide the waste, achieving arch breaking without having to approach the cutter roller 24, further enhancing the safety of equipment and personnel.

[0033] Hydraulic cylinder 33 provides continuous and uniform driving force to movable plate 3 and pressure plate 32. Compared with the dispersed force of manual tamping, mechanical drive can generate stronger arch-breaking pressure, which can quickly break the stubborn arch structure formed by grease solidification and fiber entanglement. At the same time, movable plate 3 slides and fits against the inner wall of bin 1 without shaking or shifting during movement, ensuring that pressure plate 32 always acts on the bridging area. This avoids the problem of incomplete bridging breaking caused by uneven force during manual operation, allowing kitchen waste to fall quickly to the area of ​​cutter roller 24, resuming crushing operation and reducing production interruption time.

[0034] See Figures 1-5 A screw 5 is threadedly connected to the side of the top plate 31 away from the hydraulic cylinder 33 to limit the maximum angle of expansion between the pressure plate 32 and the movable plate 3. A vertical hole is opened on the side of the top plate 31 away from the hydraulic cylinder 33. The lower end of the straight cylinder 51 is installed in the vertical hole. A round nut 52 is installed in the middle of the straight cylinder 51. The screw 5 is threadedly connected to the round nut 52. Both ends of the screw 5 extend to the outside of the straight cylinder 51. Rubber plugs 53 are provided on the upper and lower sides of the round nut 52. The rubber plugs 53 are slidably installed in the straight cylinder 51 and are sleeved on the screw 5 and kept in place by the screw 5. With the relative positions unchanged, the distance between the two rubber plugs 53 is half the height of the straight cylinder 51. A knob head is provided on the upper side of the screw 5, and a blind hole is formed by a recess in the middle of the lower surface of the knob head, so that the upper end of the screw 5 is installed in the blind hole, increasing the connection range between the screw 5 and the knob head. By rotating the screw 5, the limiting height of the lower end of the screw 5 relative to the pressure plate 32 can be adjusted. When the garbage bridging in the bin 1 is relatively loose, the length of the lower end of the screw 5 under the top plate 31 is shortened, and the unfolding angle of the pressure plate 32 is increased to expand the working area for efficient drainage. When the bridging is relatively hard, the unfolding angle is reduced so that the pressure is concentrated in a local area for rapid breaking. This adjustable design can adapt to bridging scenarios with different densities and locations, and can deal with complex kitchen waste bridging situations without replacing parts, improving versatility and flexibility in breaking bridging. The rubber plugs 53 on the upper and lower sides of the circular nut 52 inside the straight cylinder 51 can effectively prevent oil and small impurities in the kitchen waste from entering the interior of the straight cylinder 51, and prevent the screw 5 and the circular nut 52 from malfunctioning due to oil or impurities. At the same time, the rubber plugs 53 slide synchronously with the screw 5, without affecting the angle adjustment function, ensuring that the screw 5 can still be adjusted smoothly in harsh environments with high oil and impurities such as kitchen waste, and ensuring the long-term reliable operation of the device.
