DETAILED DESCRIPTION

[0026] The utility model will be explained in detail below with reference to the drawings and in combination with the embodiments.

[0027] As Figures 1 to 10 shown, an organic garbage crusher device, including cutter box 2, the cutter box 2 is cooperated with moving cutter group 3 and fixed cutter group 6, moving cutter group 3 is driven to rotate by speed reducer 4, the top of cutter box 2 is provided with feed hopper 1, and the connecting position of cutter box 2 corresponding moving cutter group 3 is provided with skeleton oil seal 26 and bearing 27, and the bottom of cutter box 2 is provided with discharge port 8;Discharge port 8 is erected on structure frame 9, and particle control screen 7 is arranged in the lower side of fixed cutter group 6 in cutter box 2;Each fixed blade 61 of fixed cutter group 6 is arranged in cutter box 2, and positioning block 10 is arranged on the inner wall of cutter box 2 on both sides of fixed cutter group 6, and the side of each fixed blade 61 is clamped on positioning block 10;The both sides of fixed blade 61 are provided with dog teeth in matrix distribution, and the dog teeth on each side are arranged obliquely, and the middle part of fixed blade 61 has concave arc portion 62;Moving cutter group 3 includes transmission shaft 31, moving blade 32 and spacer sleeve 33, transmission shaft 31 is connected with bearing 27 in cooperation, so that transmission shaft 31 is suspended on arc portion 62 and is in concentric position with arc portion 62, moving blade 32 is arranged on transmission shaft 31 in equal distribution, and spacer sleeve 33 is arranged between adjacent moving blade 32, so that each moving blade 32 is separated from each other and is located between fixed blade 61, moving blade 32 is in the form of hook, and dog teeth in matrix distribution are arranged on the two arc surfaces of moving blade 32, and moving blade 32 is in linear spiral distribution on transmission shaft 31, that is, the first moving blade 32 is regarded as zero degree, the second moving blade 32 is symmetrical with the installation position of the first moving blade 32, the third moving blade 32 is deflected by 10 ° towards the rotating direction, every other moving blade 32 is deflected by 10 ° towards the rotating direction, and the dog teeth on the large circular arc surface of moving blade 32 are greater than the dog teeth on the small circular arc surface.

[0028] As Figure 6 and Figure 7As shown, the positioning block 10 includes an upper positioning block 101 and a lower positioning block 102, the bottom end of the upper positioning block 101 and the top end of the lower positioning block 102 are both fitted with symmetrical partition blocks 103, and the side of each fixed blade 61 is clamped between adjacent partition blocks 103. The upper positioning block 101 and the lower positioning block 102 are clamped on the side wall of the cutter box 2, 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 length of the upper positioning block 101 and the lower positioning block 102 is the same as the length of the side wall of the cutter box 2, which can maximize the fixed blades 61 to cover the entire cutter box 2, the interval between the partition blocks 103 can also separate the adjacent fixed blades 61 to produce a falling space for the crushed materials, and at the same time, the fixed blades 61 are separated, which is convenient for disassembling the damaged single fixed blade 61 at any time, and the entire fixed cutter group 6 does not need to be removed, which is convenient for maintenance and maintenance.

[0029] As shown in Figure 8 The two sides of the fixed blade 61 are inclined downward to the arc-shaped part 62, and the dog teeth on the fixed blade 61 are arranged by the two sides of the fixed blade 61 downwardly inclined to the arc-shaped part 62. The fixed blade 61 in the shape of a hook can change the dog tooth matrix located on both sides from general horizontal arrangement to inclined arrangement, increase the number of dog tooth arrangement and the crushing area, and the arc-shaped part 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 cutter group 6 and the moving cutter group 3. The inclined arrangement of the dog teeth is easy to form a slope between the dog teeth, because the tips of the dog teeth are located at different heights, when the material touches the dog teeth, it is easier to be caught by the dog teeth, thereby preventing the material from slipping or sliding away. Compared with the traditional double-shaft roller crusher distributed fixed cutter, it is not easy to cause the material to be suspended and slip in place, thereby avoiding the blockage of the feed hopper 1.

[0030] As shown in Figure 9As shown, the moving blades 32 are in a linear spiral distribution on the transmission shaft 31, that is, the first moving blade 32 is regarded as zero degree, the second moving blade 32 is symmetrically installed with the first moving blade 32, the third moving blade 32 is deflected by 10° in the rotating direction, and every other moving blade 32 is deflected by 10° in the rotating direction. In the embodiment, the assembly sequence of the moving blade group 3 is as follows: first, the spacer sleeve 33 is assembled on the transmission shaft 31, then the first moving blade 32 is assembled, and the first moving blade 32 is regarded as zero degree; a spacer sleeve 33 is assembled close to the first moving blade 32, then the second moving blade 32 is assembled, and the direction is symmetric with the first moving blade 32; in this case, 27 moving blades 32 are sequentially assembled, and the direction is left-handed rotation, taking the first moving blade zero degree as the reference, the 3rd, 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th, 21st, 23rd and 25th moving blades 32 are sequentially rotated by 10°. The moving blades 32 distributed in this way have a deviation in the cutting timing of each moving blade 32 when rotating, which avoids that all the moving blades 32 uniformly cut the materials, reduces the torque of the transmission shaft 31, and enables the material grabbing range between the moving blade group 3 and the fixed blade group 6 to be larger.

[0031] As shown in the figure, Figure 10 The dog teeth on the large circular arc surface of the moving blade 32 are larger than the dog teeth on the small circular arc surface. The blade part of the moving blade 32 is in a circular arc distribution, the large circular arc is a tangent surface, the cutting area and force are large, and the dog teeth are uniformly distributed in the arc surface. When the shape of the material is large, under the relative motion between the moving blade group 3 and the fixed blade group 6, the dog teeth have the functions of grabbing, tearing, pulling down and shearing. Another function of the large circular arc surface is to reduce the pressure of the blade and the torque of the transmission shaft, so that the materials that cannot be broken once are broken twice or thrice, and finally the breaking purpose is achieved. The small circular arc is a reverse tangent surface, and its function is the same as that of the large circular arc surface. During the working process of the equipment, the materials at the root of the dog teeth can be removed through the adjustment of forward rotation and reverse rotation, so as to avoid material jamming.

[0032] The reducer 4 is lapped on the structural frame 9 in cooperation with the transmission shaft 31, and the elastic supporting rod 5 is arranged between the reducer 4 and the structural frame 9. The function of the elastic supporting rod 5 is to buffer the torque of the reducer 4 when the reducer 4 is started instantaneously, so as to play a protection role.

[0033] The moving blade 32 of the utility model is arc-shaped, the cutting surface length of the blade in the same radius range is increased, the fixed blade 61 in the shape of a hook is matched, the breaking range and radius of the equipment are increased, the material breaking range is improved, the material is grabbed firmly and does not slip or idle. The cut materials first pass through the particle control screen 7 and are finally discharged from the discharge port 8. Since the transmission shaft 31 is suspended on the arc-shaped parts 62 of the fixed blades 61 and is in a concentric position with the arc-shaped parts 62, the concentricity with the arc-shaped parts 62 is maintained, and a certain gap is also maintained, that is, the shearing is realized through the interaction during the working process, and the arc-shaped parts 62 can be separated independently, so that the assembly and maintenance are simple and fast, and the assembly time is greatly saved.

[0034] As Figure 11 shown, the cutter box 2 includes a front box plate 21, a bearing cover 22, a leakage prevention 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 connected with the transmission shaft 31, 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 matched with the transmission shaft 31 and a bearing 27, the front box plate 21 and the rear box plate 24 are both provided with the bearing cover 22 outside the bearing 27, the front box plate 21 is provided with a detachable front sliding block 28 corresponding to the connection of the transmission shaft 31, the rear box plate 24 is provided with a detachable rear sliding block 29 corresponding to the connection of the transmission shaft 31, the front sliding block 28 and the rear sliding block 29 are both arranged at the top of the transmission shaft 31, the leakage prevention plate 23 is arranged at the inner side of the front box plate 21 and the rear box plate 24, the leakage prevention plate 23 separates the fixed cutter set 6 from the front box plate 21 and the rear box plate 24, the leakage prevention plate 23 is provided with a detachable leakage prevention sliding block 30 corresponding to the connection of the transmission shaft 31, and the leakage prevention sliding block 30 is arranged at the top of the transmission shaft 31.

[0035] When a certain moving cutter blade 32 in the moving cutter set 3 needs to be replaced and repaired, the cutter box 2 can not be disassembled as a whole, the connecting pieces on the front sliding block 28 and the rear sliding block 29 of the front box plate 21 and the rear box plate 24 are first disassembled, and then the front sliding block 28 and the rear sliding block 29 are taken out. Then the connecting pieces on the leakage prevention sliding block 30 are disassembled, the leakage prevention sliding block 30 is taken out from the leakage prevention plate 23, and the top of the transmission shaft 31 becomes an open state, so that the moving cutter set 3 can be taken out from the cutter box 2. Without disassembling the entire cutter box 2, the replacement and repair of the moving cutter set 3 are facilitated. When a certain fixed cutter blade 61 in the fixed cutter set 6 needs to be replaced and repaired, on the basis of disassembling the front sliding block 28, the rear sliding block 29 and the leakage prevention sliding block 30, the front box plate 21 can be disassembled as a whole. Compared with the integrally formed cutter box, the cutter box 2 formed by a plurality of box plates and sliding blocks is more convenient for later maintenance.

[0036] The gap between the leakage prevention plate 23 and the front box plate 21 and the rear box plate 24 is 1-2 cm. The gap can make the dust, oil, water and particulate matter generated during the crushing of the material slide down from the gap, and cannot easily enter the skeleton oil seal 26 and the bearing 27, thereby effectively protecting and prolonging the service life of the skeleton oil seal 26 and the bearing 27.

[0037] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
