Description

Technical Field

[0001] This utility model relates to the field of kitchen waste pulverizer filter replacement technology, specifically, to a kitchen waste pulverizer that facilitates filter replacement. Background Technology

[0002] In the process of treating kitchen waste, crushing and pulping is the main technological method. Currently, when crushing kitchen waste, fixed blades and rotating blades on the container are used to shear the kitchen waste to pulverize it. The pulverized waste will be discharged through the filter screen, while waste that is not pulverized to the appropriate size will be blocked by the filter screen and then sheared again by the fixed blades and rotating blades.

[0003] During use, the filter screen may become clogged with kitchen waste. Therefore, after a period of use, the filter screen needs to be replaced and cleaned by the worker to ensure its normal operation. Before replacing the filter screen, the worker needs to remove the cover installed on the machine body and then flip it over. For example, a special crushing and pulping machine with patent number 201810882532.0 uses two hydraulic cylinders on both sides of the machine body to drive two protective covers to flip over, and then the worker can replace the filter screen inside the machine body. However, setting up hydraulic cylinders requires adding a hydraulic circuit system to the pulping machine, which increases the manufacturing cost. At the same time, after the two protective covers are opened, they block the sides of the machine body, making it difficult for the worker to climb to the top of the machine body. The worker has to climb up from the part of the machine body away from the filter screen each time, which makes it more difficult for the worker to replace the filter screen. Utility Model Content

[0004] The purpose of this invention is to provide a kitchen waste pulverizer that facilitates filter replacement, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a kitchen waste pulverizer with easy-to-replace filter screen, comprising a housing, a feeding box located near one end of the upper side of the housing, a cover located on one side of the feeding box, a pulverizing chamber opened on the upper side of the housing, the cover covering the top of the pulverizing chamber, the cover including two rear protective covers and two front protective covers, one of which and one of which are a group located on one side of the housing, slide tubes fixed on both sides of the housing located on the cover, one end of each of the rear and front protective covers being connected to the slide tubes via a moving auxiliary component, and a receiving component located on the side of the slide tube away from the housing, after the rear and front protective covers are rotated 90 degrees, the receiving component receives the side walls of the rear and front protective covers, and after receiving the receiving component, the rear and front protective covers are moved away from each other, so that the rear and front protective covers are moved away from the sides where the cover was originally placed.

[0006] As a further improvement to this technical solution, the rear protective cover and the front protective cover are in an inverted L-shape, and two flip-connecting plates are fixed on one side of the rear protective cover and the front protective cover near the bottom. The flip-connecting plates are provided with sockets at the ends away from the rear protective cover and the front protective cover, and the sliding tube is placed in the sockets.

[0007] As a further improvement to this technical solution, an edge strip is fixed at the outer edge of the top of the box, and an extension strip is fixed at the edge strip away from the feed box. Adhesive strips are fixed at both ends of the rear protective cover and the front protective cover. When the machine cover covers the upper side of the feed box, the adhesive strip on the lower side contacts the handle. At the same time, handles are fixedly installed at the horizontal sections of the rear protective cover and the front protective cover, as well as at the connection between the horizontal and vertical sections.

[0008] As a further improvement to this technical solution, the moving auxiliary component includes a mounting shell fixed with screws between two flip connecting plates. The mounting shell has a mounting cavity inside, and several moving parts are installed in the mounting cavity. The moving parts are used to assist the rotation and movement of the rear protective cover and the front protective cover. At the same time, a sealing plate is fixed with screws on one side of the mounting shell, and the sealing plate seals one side of the mounting cavity.

[0009] As a further improvement to this technical solution, the moving part includes two U-shaped sleeves, which are fixedly connected by several fixing strips. Each sleeve includes two straight sections and an arc-shaped end connecting the two straight sections. A translation roller is rotatably connected to the middle of the arc-shaped section. The axis of the translation roller is perpendicularly intersecting the axis of the slide tube. Several rotating rollers are rotatably connected near the connection between the straight and arc-shaped sections. The axis of the rotating rollers is parallel to the axis of the slide tube.

[0010] As a further improvement to this technical solution, the sidewalls of the rotating roller and the translation roller are in contact with the sidewall of the slide tube. When the rear protective cover and the front protective cover rotate, the rotating roller and the outer sidewall of the slide tube roll in contact. When the rear protective cover and the front protective cover translate, the translation roller and the slide tube roll in contact.

[0011] As a further improvement to this technical solution, a stop block is fixed to the lower side of the end of the flip-connecting plate away from the rear protective cover and the front protective cover. When the rear protective cover and the front protective cover are flipped 90 degrees, one side of the stop block contacts the bottom of the edge strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this kitchen waste pulverizer with easy-to-replace filter screen, the top of the chamber is protected by multiple rear and front protective covers combined together. When it needs to be flipped over, workers can manually pull the rear and front protective covers separately, eliminating the need for hydraulic cylinders and other devices, thus reducing the cost of the device. After the rear and front protective covers are flipped over, they are supported by a receiving component and then pushed away from each other, moving them to the sides of the chamber. This ensures that the rear and front protective covers do not obstruct the filter screen replacement position, allowing workers to climb directly onto the chamber from the location where the filter screen is installed. Furthermore, when replacing the filter screen, it can be directly delivered from the side of the chamber, making filter screen replacement convenient for workers. Attached Figure Description

[0028] Example 1

[0029] Please see Figures 1-7 As shown, this embodiment provides a kitchen waste pulverizer with easy-to-replace filter screens, including a housing 1. A feed box 11 is provided on the upper side of the housing 1 near one end. An organic cover is provided on one side of the feed box 11. A pulverizing chamber is opened on the upper side of the housing 1. Several filter screens 12 are installed in the pulverizing chamber. The several filter screens 12 are combined to form a cylindrical structure. A pulverizing mechanism is provided between the several filter screens 12. The kitchen waste entering the housing 1 from the feed box 11 is pulverized by the pulverizing mechanism. The pulverized waste flows out from the filter screens 12. The above-described usage process is the structure of an existing pulverizer, which will not be described in detail here.

[0030] When the pulper is in normal use, the cover covers the top of the crushing chamber. The improvement of this solution is that the cover includes two rear protective covers 2 and two front protective covers 21. One rear protective cover 2 and one front protective cover 21 are a group and located on one side of the box body 1. That is, one rear protective cover 2 and one front protective cover 21 are combined to form half of the cover. The rear protective cover 2 and the front protective cover 21 are inverted L-shaped, each including a horizontal section and a vertical section. Two flip-connecting plates 22 are fixed on one side of the rear protective cover 2 and the front protective cover 21 near the bottom. The flip-connecting plates 22 are fixed on the vertical section. The flip-connecting plates 22 have slots at the ends away from the rear protective cover 2 and the front protective cover 21. Slide tubes 15 are fixed on both sides of the box body 1 located on the cover. The slide tubes 15 are placed in the slots. One end of the rear protective cover 2 and the front protective cover 21 are connected to the slide tubes 15 through the moving auxiliary parts 4.

[0031] An edge strip 13 is fixed to the outer edge of the top of the housing 1. An extension strip 14 is fixed to the edge strip 13 away from the feed box 11. The bottoms of the edge strip 13 and the extension strip 14 are on the same plane, and the sides of the edge strip 13 and the extension strip 14 away from the housing 1 are on the same vertical plane. Adhesive strips 24 are fixed to both ends of the rear protective cover 2 and the front protective cover 21. When the machine cover covers the upper side of the feed box 11, the adhesive strips 24 on the two rear protective covers 2 and the two front protective covers 21 contact each other and pass through... Bolts are used to fix the front protective cover 21 and the rear protective cover 2 in contact with each other. In order to ensure the sealing between the front protective cover 21 and the rear protective cover 2, a pressure strip is fixed on the front protective cover 21 near the rear protective cover 2. The pressure strip contacts the side wall of the rear protective cover 2 and covers the gap between the rear protective cover 2 and the front protective cover 21 to ensure the sealing between the rear protective cover 2 and the front protective cover 21. The adhesive strip 24 located on the lower side contacts the handle 23 and is connected with bolts.

[0032] Meanwhile, handles 23 are fixedly installed on the horizontal sections of the rear protective cover 2 and the front protective cover 21, as well as at the connection points between the horizontal and vertical sections. Four handles 23 are installed on each of the rear and front protective covers 21. A stop block 25 is fixed to the lower side of the end of the flip-connecting plate 22 away from the rear and front protective covers 21. When the rear and front protective covers 2 and 21 are flipped 90 degrees, one side of the stop block 25 contacts the bottom of the edge strip 13. When the stop block 25 contacts the bottom of the edge strip 13, the edge strip 13 blocks the movement of the stop block 25. The stopped block 25, having been blocked, fixes the position of the flip-connecting plate 22, preventing the rear and front protective covers 21 from rotating. To ensure the stability of the rear and front protective covers 2 and 21 after flipping 90 degrees, a receiving component 3 is provided on the side of the slide tube 15 away from the housing 1. The receiving component 3 includes a horizontal plate and a component hinged to the horizontal plate. Several rollers and a horizontal plate are fixed to the housing 1 by a mounting bracket. After the rear protective cover 2 and the front protective cover 21 are rotated 90 degrees, the receiving part 3 receives the side walls of the rear protective cover 2 and the front protective cover 21. That is, several rollers contact the side walls of the rear protective cover 2 and the front protective cover 21. After the receiving part 3 receives the side walls, the worker pushes the rear protective cover 2 and the front protective cover 21 away from each other, so that the rear protective cover 2 and the front protective cover 21 are moved away from the sides where the cover was originally placed. When the rear protective cover 2 and the front protective cover 21 are moved away from the sides where the cover was originally placed, the position where the cover is installed on the housing 1 is exposed. The worker can directly climb to the position where the filter screen 12 is installed. When the filter screen 12 is subsequently disassembled and replaced, it can be directly taken from one side of the housing 1, making it more convenient for the worker to replace the filter screen 12.

[0033] To ensure the stable rotation of the rear protective cover 2 and the front protective cover 21, the structure of the moving auxiliary component 4 is detailed below. The moving auxiliary component 4 includes a mounting shell 41 fixed with screws between two flip connecting plates 22. One moving auxiliary component 4 is fixed between two flip connecting plates 22 on a rear protective cover 2 or a front protective cover 21. A mounting cavity is provided inside the mounting shell 41, and several moving parts are installed in the mounting cavity. The moving parts are used to assist the rotation and movement of the rear protective cover 2 and the front protective cover 21. At the same time, a sealing plate 46 is fixed with screws on one side of the mounting shell 41. The sealing plate 46 seals one side of the mounting cavity. The sealing plate 46 seals the mounting cavity to prevent the moving auxiliary component 4 from separating from the slide tube 15 and to prevent foreign objects from entering the interior of the mounting cavity.

[0034] The movable component includes two U-shaped sleeve plates 42, which are fixedly connected by several fixing strips 43. Several movable components are sequentially fixedly connected by bolts, which are fixed to the sleeve plates 42 in the two movable components. The movable components at both ends are fixed to the side walls of the mounting housing 41 by bolts. Each sleeve plate 42 includes two straight sections and an arc-shaped end connecting the two straight sections. A translation roller 45 is rotatably connected to the middle of the arc-shaped section. The axis of the translation roller 45 is perpendicularly intersecting the axis of the slide tube 15. Several rotating rollers 44 are rotatably connected near the connection between the straight section and the arc-shaped section. Several rotating rollers 44 extend toward the translation rollers 45, meaning the rotating rollers 44 are not installed on the straight section. The axis of the rotating rollers 44 is parallel to the axis of the slide tube 15. The sidewalls of the rotating rollers 44 and the translation rollers 45 are in contact with the sidewalls of the slide tube 15. When the rear protective cover 2 and the front protective cover 21 rotate, the rotating rollers 44 and the outer sidewalls of the slide tube 15 roll in contact. When the rear protective cover 2 and the front protective cover 21 translate, the translation rollers 45 and the slide tube 15 roll in contact. The contact between the rotating rollers 44 and the translation rollers 45 and the sidewalls of the slide tube 15 facilitates the rotation and translation of the rear protective cover 2 and the front protective cover 21.

[0035] Regardless of whether the rear protective cover 2 and the front protective cover 21 rotate or translate, the translation roller 45 and the rotating roller 44 are always in contact with the side wall of the slide tube 15. The contact between the rotating roller 44 and the translation roller 45 and the side wall of the slide tube 15 ensures the stability of the moving auxiliary component 4 installed on the slide tube 15. There will be no shaking when the rear protective cover 2 and the front protective cover 21 rotate. At the same time, the rear protective cover 2 and the front protective cover 21 are both composed of steel frame and iron sheet. This method can reduce the weight of the rear protective cover 2 and the front protective cover 21 while ensuring the protective effect of the rear protective cover 2 and the front protective cover 21. The slide tube 15, the rotating roller 44 and the translation roller 45 are all made of steel, which can extend the wear time. In addition, the frequency of replacing the filter screen 12 is not frequent, which makes the service life of the moving auxiliary component 4 longer.

[0036] The top of the housing 1 is protected by a combination of multiple rear protective covers 2 and front protective covers 21. When it needs to be flipped, workers can manually pull the rear protective covers 2 and front protective covers 21 respectively, eliminating the need for hydraulic cylinders and other devices, thus reducing the cost of device manufacturing. After the rear protective covers 2 and front protective covers 21 are flipped, they are supported by the receiving parts 3, and then pushed to a position away from each other, so that the rear protective covers 2 and front protective covers 21 move to the sides of the housing 1, so that the rear protective covers 2 and front protective covers 21 do not obstruct the position for replacing the filter screen 12. This allows workers to climb directly onto the housing 1 from the position where the filter screen 12 is installed. At the same time, when replacing the filter screen 12, it can also be sent directly from the side of the housing 1, making it convenient for workers to replace the filter screen 12.

[0037] When using this device:

[0038] When the filter 12 needs to be replaced, the worker removes all the bolts securing the rear protective cover 2 and the front protective cover 21. Then, two workers pull on the same front protective cover 21. While pulling, the two workers pull on the handles 23 fixed at the connection between the vertical and horizontal sections of the front protective cover 21, causing the front protective cover 21 to be pulled away from the other front protective cover 21. At this time, the front protective cover 21 will drive the flip connecting plate 22 to move. The moving auxiliary part 4 then blocks the flip connecting plate 22, causing the front protective cover 21 to rotate around the axis of the slide tube 15. During the rotation, two workers put their other hand in contact with another handle 23, and then continue to pull the other handle 23. At the same time, after the front protective cover 21 rotates 45 degrees, the front protective cover 21 begins to rotate automatically downward due to gravity. At this time, the workers lift the front protective cover 21 through the handle 23 and slowly lower the front protective cover 21 so that the side wall of the front protective cover 21 contacts the roller on the receiving part 3. After the front protective cover 21 is placed, the stop block 25 contacts the bottom of the edge strip 13. The workers push the front protective cover 21 so that the front protective cover 21 moves away from the rear protective cover 2.

[0039] Repeat the above operation to open and move away all the remaining rear protective cover 2 and front protective cover 21, so that the position where the filter screen 12 is installed on the box 1 is fully exposed. Workers can directly remove and install the filter screen 12 at the position where it is installed. At the same time, moving away the rear protective cover 2 and front protective cover 21 also avoids the rear protective cover 2 and front protective cover 21 from hindering the workers from removing the filter screen 12, further reducing the difficulty for workers to replace the filter screen 12.

[0040] To ensure that the rear protective cover 2 and the front protective cover 21 can accurately cover the top of the housing 1 during installation, two retaining rings 16 are fixed on the slide tube 15. The two retaining rings 16 respectively block the flip connecting plate 22 on the rear protective cover 2 and the front protective cover 21, thereby ensuring that the rear protective cover 2 and the front protective cover 21 can accurately cover the top of the housing 1.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
