Description

Technical Field

[0001] The invention relates to the technical field of garbage processing equipment, and in particular to an organic garbage crusher equipment. Background Art

[0002] In the field of organic waste treatment, crushers play a critical and important pre-treatment role. Because the size, shape, and dimensions of the collected kitchen, fruit and vegetable organic waste are different, the homogeneity is poor, and the viscosity is high, it must be processed by the crusher into particles of 0.8-1.5 cm in size before the next step of waste treatment can be carried out. The crushing of garbage is particularly important. Most of the crushing systems widely used on the market are double-axis roller crushers, which are made by the relative movement of the moving knife, the auxiliary role of the fixed knife, and the engagement of the moving knives to each other to generate shearing, tearing and squeezing forces to turn large materials into small particles. At present, this type of crusher equipment has the following disadvantages: 1. The equipment has low production efficiency and low material processing efficiency. For example, in actual applications, flexible and fibrous materials are prone to entanglement, the engagement or positioning of the moving knife and the fixed knife on the material is not firm, it is not easy to grasp the material, and it is easy to slip in place without feeding, resulting in material accumulation in the feed hopper. 2. The moving blade has a small crushing area, a small crushing radius or a small depth, so that the material in the feed hopper cannot be caught as long as it exceeds the cutting radius of the moving blade, causing the material to be suspended, the equipment to run idle, and the material to accumulate in the feed hopper. Therefore, there is an urgent need for an organic waste crusher that has high material crushing efficiency, is not prone to material accumulation, has a large crushing range and depth, and is easy to repair and disassemble the blade. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and to provide an organic waste crusher device which has high material crushing efficiency, is not prone to material accumulation, has a large crushing range and depth, and is easy to maintain and disassemble the blades.

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] like Figures 1 to 10As shown, an organic waste crusher device comprises a knife box 2, wherein a moving knife group 3 and a fixed knife group 6 are matched in the knife box 2, the moving knife group 3 is driven to rotate by a reducer 4, a feed hopper 1 is arranged on the top of the knife box 2, a skeleton oil seal 26 and a bearing 27 are arranged at the connection position of the knife box 2 corresponding to the moving knife group 3, and a discharge port 8 is arranged at the bottom of the knife box 2; the discharge port 8 is mounted on a structural frame 9, and a particle control screen 7 is arranged at the lower side of the fixed knife group 6 in the knife box 2; each fixed blade 61 of the fixed knife group 6 is arranged in the knife box 2, and positioning blocks 10 are arranged on the inner wall of the knife box 2 on both sides of the fixed knife group 6, and the side of each fixed blade 61 is clamped on the positioning block 10; Both sides of the fixed blade 61 are provided with canine teeth distributed in a matrix, and the canine teeth on each side are arranged obliquely. The middle part of the fixed blade 61 has a concave arc portion 62; the movable knife group 3 includes a transmission shaft 31, a movable blade 32 and a spacer sleeve 33. The transmission shaft 31 is connected with the bearing 27 so that the transmission shaft 31 is suspended on the arc portion 62 and is in a concentric position with the arc portion 62. The movable blades 32 are evenly arranged on the transmission shaft 31, and the spacer sleeves 33 are arranged between adjacent movable blades 32 so that each movable blade 32 is separated from each other and located between the fixed blades 61. The movable blade 32 is hook-shaped, and the two arc surfaces of the movable blade 32 are provided with canine teeth distributed in a matrix.

[0030] like Figure 6 and Figure 7 As shown, the positioning block 10 includes an upper positioning block 101 and a lower positioning block 102, and the bottom end of the upper positioning block 101 and the top end of the lower positioning block 102 are both provided with symmetrical spacers 103, and the side portions of each fixed blade 61 are all clamped between adjacent spacers 103. The upper positioning block 101 and the lower positioning block 102 are both clamped on the side wall of the knife box 2, and the position between the upper positioning block 101 and the lower positioning block 102 can be used to install each fixed blade 61, and the upper positioning block 101 and the lower positioning block 102 have the same length as the side wall of the knife box 2, which can maximize the fixed blade 61 to cover the entire knife box 2, and the interval between the spacers 103 can also separate the adjacent fixed blades 61, creating a falling space for the cutter fragments, and at the same time separate the fixed blades 61, so that it is convenient to disassemble the damaged single fixed blade 61 at any time, and it is not necessary to dismantle the fixed blade group 6 as a whole, which is convenient for repair and maintenance.

[0031] like Figure 8As shown, both sides of the fixed blade 61 are tilted downward to the arc-shaped portion 62, and the canine teeth on the fixed blade 61 are tilted downward toward the arc-shaped portion 62 from both sides of the fixed blade 61. The hook-shaped fixed blade 61 can change the canine tooth matrix on both sides from the general horizontal arrangement to an inclined arrangement, increasing the number of canine teeth arranged and the crushing area. The arc-shaped portion 62 is located at the lowest position, which increases the crushing depth of the blade, thereby increasing the crushing range and radius between the fixed blade group 6 and the moving blade group 3. The inclined arrangement of canine teeth makes it easy to form a slope between the canine teeth. Since the tips of the canine teeth are located at different heights, when the material touches the canine teeth, it is easier to be bitten by the canine teeth, so that the material is not easy to slip or slip away. Compared with the distributed fixed blades of the traditional double-shaft roller crusher, it is not easy for the material to be suspended or slip in place, thereby avoiding the blockage of the feed hopper 1.

[0032] like Fig. 9 As shown, the movable blades 32 are arranged in a straight spiral on the transmission shaft 31, that is, the first movable blade 32 is regarded as zero degree, the second movable blade 32 is installed symmetrically with the first movable blade 32, the third movable blade 32 is deflected 10° in the direction of rotation, and every other movable blade 32 is deflected 10° in the direction of rotation. The assembly order of the movable blade group 3 in this embodiment is: first install the spacer 33 on the transmission shaft 31, and then install the first movable blade 32, and the first movable blade 32 is regarded as zero degree; install a spacer 33 close to the first movable blade 32, and then install the second movable blade 32, and the direction is symmetrical with the first movable blade 32; in this case, 27 movable blades 32 are installed in sequence, the direction is left-handed, and the 3rd, 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th, 21st, 23rd, and 25th movable blades 32 are rotated 10° in sequence based on the zero degree of the first movable blade. When the movable blades 32 distributed in this manner rotate, the cutting timing of each movable blade 32 is deviated, which avoids all movable blades 32 from cutting the material uniformly, reduces the torque of the transmission shaft 31, and increases the material grabbing range between the movable blade group 3 and the fixed blade group 6.

[0033] like Fig.10 As shown, the canine teeth on the large arc section of the movable blade 32 are larger than the canine teeth on the small arc section. The blade of the movable blade 32 is distributed in an arc shape, and the large arc is a positive section, with a large cutting area and force, and the canine teeth are evenly distributed on the arc surface. When the material is large in shape, when the movable blade group 3 and the fixed blade group 6 move relative to each other, the canine teeth have the functions of grabbing, tearing, pulling down, and shearing. Another function of the large arc section is to reduce the pressure of the blade and the torque of the transmission shaft, so that the larger material cannot be crushed at one time, and it is crushed twice or three times to finally achieve the purpose of crushing. The small arc is a negative section, and its function is the same as that of the large arc surface. During the operation of the equipment, the material at the root of the canine teeth can be removed by adjusting the forward and reverse rotation to avoid plugging.

[0034] The reducer 4 is overlapped on the structural frame 9 with the transmission shaft 31, and an elastic support rod 5 is arranged between the reducer 4 and the structural frame 9. The function of the elastic support rod 5 is to buffer the torque of the reducer 4 when the reducer 4 is started instantly, so as to play a protective role.

[0035] The movable blade 32 of the present invention is in the shape of an arc, so that the cutting surface length of the blade within the same radius is increased, and combined with the fixed blade 61 in the shape of a hook, the crushing range and radius of the equipment are increased, the material crushing range is improved, the material is firmly grasped, there is no slipping, and there is no idling. The cut material first passes through the particle control screen 7 and is finally discharged from the discharge port 8. Since the transmission shaft 31 is suspended on the arc-shaped portion 62 of each fixed blade 61 and is in a concentric position with the arc-shaped portion 62, it not only maintains concentricity with the arc-shaped portion 62, but also maintains a certain gap. When working, they can shear each other and can be disassembled independently. Each is integrated, making assembly and maintenance simple and quick, greatly saving assembly time.

[0036] like Fig.11 As shown, the knife box 2 includes a front box plate 21, a bearing cover 22, an anti-leakage plate 23, a rear box plate 24 and a side box plate 25. The front box plate 21 and the rear box plate 24 are respectively located at the front and rear ends of the transmission shaft 31, and the side box plate 25 is connected between the front box plate 21 and the rear box plate 24. The front box plate 21 and the rear box plate 24 are both provided with a skeleton oil seal 26 and a bearing 27 that cooperate with the transmission shaft 31. The front box plate 21 and the rear box plate 24 are both provided with a bearing cover 22 on the outside of the bearing 27. The front box plate 21 corresponds to the connection of the transmission shaft 31. A detachable front slider 28 is provided at the connection of the rear box plate 24 corresponding to the transmission shaft 31. A detachable rear slider 29 is provided. The front slider 28 and the rear slider 29 are both arranged on the top of the transmission shaft 31. The anti-leakage plates 23 are both arranged on the inner sides of the front box plate 21 and the rear box plate 24. The anti-leakage plates 23 separate the fixed knife group 6 from the front box plate 21 and the rear box plate 24. A detachable anti-leakage slider 30 is provided at the connection of the anti-leakage plate 23 corresponding to the transmission shaft 31. The anti-leakage sliders 30 are all arranged on the top of the transmission shaft 31.

[0037] When a moving blade 32 in the moving blade group 3 is damaged and needs to be replaced and repaired, the knife box 2 does not need to be dismantled as a whole. First, the connecting pieces on the front slider 28 and the rear slider 29 on the front box plate 21 and the rear box plate 24 are removed, and the front slider 28 and the rear slider 29 are taken out. Then, the connecting piece on the anti-leakage slider 30 is removed, and the anti-leakage slider 30 is taken out from the anti-leakage plate 23. The top of the transmission shaft 31 becomes open, and the moving blade group 3 can be taken out from the knife box 2. Without dismantling the entire knife box 2, it is convenient to replace and repair the moving blade group 3. When a fixed blade 61 in the fixed blade group 6 is damaged and needs to be replaced and repaired, the front box plate 21 can be dismantled as a whole on the basis of removing the front slider 28, the rear slider 29 and the anti-leakage slider 30. Compared with the integrally formed knife box, the knife box 2 composed of multiple box plates and sliders is more convenient for later maintenance.

[0038] There is a gap of 1-2 cm between the anti-leakage plate 23 and the front box plate 21 and the rear box plate 24. The gap allows dust, oil, water and particles generated when crushing materials to slide down through the gap first, and will not easily enter the skeleton seal 26 and the bearing 27, which effectively protects and prolongs the service life of the skeleton oil seal 26 and the bearing 27 to a great extent.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
