DETAILED DESCRIPTION

[0029] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0030] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0031] Figures 1 to 9 The schematic diagram of the structure of a garbage compression mechanism according to a preferred embodiment of the present invention is shown. The garbage compression mechanism comprises a housing 1 , a gate 4 , a guide pressure plate 11 , a pusher head 2 and a rotating pressure plate 3 .

[0032] refer to Figures 1 to 9, a cavity 5 is provided in the shell 1, and a garbage delivery cavity 51, a compression cavity 53 and a pre-compression cavity 52 are provided in the cavity 5. The pre-compression cavity 52 is located below the garbage delivery cavity 51, and the top front side of the pre-compression cavity 52 is interconnected with the garbage delivery cavity 51, so that the garbage in the garbage delivery cavity 51 can fall into the pre-compression cavity 52 under the action of gravity. The bottom of the pre-compression cavity 52 is an arc shape with an opening facing upward, which is convenient for the subsequent rotating pressure plate 3 to perform pre-compression operation on the garbage. The compression cavity 53 is located at the top rear side of the pre-compression cavity 52, which is used for secondary compression of the garbage. A feeding port 15 is provided on the front side of the garbage delivery cavity 51, which is convenient for the delivery of garbage. A discharge port is provided at the rear end of the compression cavity 53, and when the garbage is pre-compressed and secondary compressed, the garbage is discharged from the discharge port. The gate 4 is connected to the discharge port in an openable and closable manner, and is used to open and close the discharge port. The guide pressure plate 11 is installed on the top of the compression cavity 53, which is used to separate the garbage delivery cavity 51 from the compression cavity 53. The push head 2 is installed in the compression chamber 53 and arranged opposite to the discharge port. The push head 2 can move forward and backward, and the push head 2 is driven to move forward and backward by a moving mechanism, so that the push head 2 can compress the garbage in the compression chamber 53 and push the compressed garbage to the discharge port. The lower end of the rotating pressure plate 3 is rotatably installed in the pre-compression chamber 52, and the rotating pressure plate 3 is driven to rotate by a rotating mechanism. The lower end of the rotating pressure plate 3 is arc-shaped. In the initial state, the rotating pressure plate 3 is located at the front side of the push head 2, opening the connection channel between the garbage delivery chamber 51 and the pre-compression chamber 52, so that the garbage in the garbage delivery chamber 51 can be normally delivered into the pre-compression chamber 52. When the rotating pressing plate 3 rotates counterclockwise to scrape the material, the upper end of the rotating pressing plate 3 can contact the bottom of the arc-shaped pre-compression chamber 52, that is, the length from the center of the rotating shaft of the rotating pressing plate to the free end is equal to the radius of the arc-shaped pre-compression chamber, so that all the garbage in the pre-compression chamber 52 is compressed into the compression chamber 53, and the garbage is prevented from being stuck in the gap between the rotating pressing plate 3 and the bottom of the pre-compression chamber 52. At the same time, the moving mechanism drives the push head 2 to move forward to the position where the lower end of the push head 2 contacts the lower end of the rotating pressing plate 3. When the lower end of the push head contacts the lower end of the rotating pressing plate 3, the compression chamber 53 and the pre-compression chamber 52 are sealed, and the garbage is prevented from flowing out of the gap between the push head and the rotating pressing plate 3 when the rotating pressing plate 3 is pre-loading the garbage, thereby ensuring the compression effect. When the rotating pressing plate 3 rotates counterclockwise to a position perpendicular to the pushing head 2, the rotating pressing plate 3, the pushing head 2 and the guide pressure plate 11 surround the compression chamber 53. When the push head 2 moves backward to the discharge port, the rotary pressing plate 3 can continue to rotate counterclockwise and return to its original position.The garbage compression mechanism of the present invention first uses the rotary pressing plate 3 of the pre-compression chamber 52 for rotational pre-compression, and then uses the push head 2 to perform secondary compression on the pre-compressed garbage. The structure is compact, and the combination of rotary pre-compression and push head 2 compression can make full use of space, reduce structural size and height, occupy a small space, have a good compression effect, short stroke, and high efficiency; and the final material compression molding in the compression chamber 53 is at a high position, and the moisture of the material can fall smoothly and will not stay in the compression chamber 53 layer. At the same time, the rotary pressing plate 3 can be directly driven by an electric motor or a hydraulic motor for compression, and the energy consumption conversion efficiency is higher. The movement speed of the rotary pressing plate 3 is faster than that of the oil cylinder driving the push head, and the processing efficiency is effectively improved.

[0033] refer to Figures 1 to 9 The compression chamber 53 can be arranged horizontally or inclined. Preferably, the compression chamber 53 is arranged horizontally; or, the compression chamber 53 is arranged inclined downward from front to back. The staff can select according to actual needs.

[0034] refer to Figures 2 to 7 The gate 4 can be opened and closed by rotation or by movement. Preferably, a guide mechanism 12 is provided on the outside of the discharge port, and the gate 4 is installed in the guide mechanism 12 in a manner that it can slide up and down, and the gate 4 is driven by the gate mechanism to slide up and down. The gate mechanism can be a hydraulic cylinder structure, and the hydraulic cylinder is extended and retracted to drive the gate 4 to slide up and down to open and close the discharge port.

[0035] refer to Figure 5 Preferably, the left and right sides of the cavity 5 are provided with front-rear guiding grooves 13 at positions corresponding to the push head 2, and the push head 2 is provided with sliders corresponding to the grooves 13 at positions corresponding to the grooves 13, so as to facilitate the forward and backward movement of the push head 2.

[0036] refer to Figure 8 and Fig. 9 The moving mechanism can be a screw nut structure or a hydraulic cylinder structure. Preferably, the moving mechanism includes two push head hydraulic cylinders, which are installed in the cavity 5 in parallel, and the rear end of the push head hydraulic cylinder is connected to the push head 2, and the front end of the push head hydraulic cylinder is connected to the housing 1, which is used to drive the push head 2 to move forward and backward. Among them, the distance between the two push head hydraulic cylinders is greater than the width of the rotating pressure plate 3 in the left and right direction, so that the rotating pressure plate 3 can be rotated counterclockwise to return to its original position.

[0037] refer to Figures 2 to 5 Preferably, the bottom surface of the guide pressure plate 11 is perpendicular to the push head 2 to facilitate the movement of the push head 2; and the top surface of the guide pressure plate 11 is inclined upward from front to back, so that the garbage delivery cavity 51 is funnel-shaped with a larger top and a smaller bottom, which facilitates the garbage to fall into the pre-compression cavity.

[0038] refer to Figures 2 to 5Preferably, a rotating shaft is provided at the lower end of the rotating platen 3, and a shaft hole 14 is provided at a position corresponding to the rotating shaft in the housing 1, and the rotating shaft extends outward through the shaft hole 14. The rotating mechanism includes a reducer and a hydraulic motor, and the hydraulic motor is connected to the rotating shaft through the reducer to drive the rotating shaft to rotate, thereby driving the rotating platen 3 to rotate.

[0039] refer to Figure 6 and Figure 7 In order to prevent the rotating pressure plate 3 from rotating in the opposite direction due to excessive force, preferably, the garbage compression mechanism also includes an anti-rebound device 6, which is used to lock the rotating pressure plate 3 in a position perpendicular to the push head 2 to prevent the rotating pressure plate 3 from rotating in the opposite direction, making it easier for the push head 2 to perform secondary compression operation on the garbage, thereby ensuring that the garbage compression work can proceed normally.

[0040] refer to Figure 6 and Figure 7 , the anti-rebound device 6 can be a bayonet structure, or a bayonet and an anti-rebound hydraulic cylinder and other structures. Preferably, the anti-rebound device 6 includes a bayonet 61 and an anti-rebound hydraulic cylinder 62, and a through hole for the bayonet 61 to pass through is provided on the side wall of the pre-pressing chamber 52, and the bayonet 61 is installed on the outer wall of the shell 1 in a manner that it can slide in the through hole. In the initial state, the inner end of the bayonet 61 is located in the through hole to prevent it from interfering with the rotation of the rotating pressing plate 3. When the rotating pressing plate 3 rotates to a position perpendicular to the push head 2, the bayonet 61 is driven to move inward, and the bayonet 61 can be extended into the pre-pressing chamber 52, and contact with the bottom surface of the rotating pressing plate 3 to prevent the rotating pressing plate 3 from rotating in the opposite direction; when the lock is released, it is only necessary to drive the bayonet 61 to move outward so that the inner end of the bayonet 61 is located in the through hole to prevent the bayonet 61 from interfering with the rotating pressing plate 3 to rotate and press the material. The anti-rebound hydraulic cylinder 62 is installed on the outer wall of the housing 1 and connected to the bayonet 61, and is used to drive the bayonet 61 to slide along the through hole, with a simple structure and convenient driving. Among them, the bayonet 61 can be in a straight shape or a U shape. Further preferably, the bayonet 61 is in a U shape.

[0041] refer to Figure 8 and Fig. 9When in use, the garbage enters from the feeding port 15 and falls into the pre-compression chamber 52 under the action of gravity. The hydraulic motor drives the rotating pressing plate 3 to rotate counterclockwise through the reducer to pre-compress the garbage in the pre-compression chamber 52 and press the garbage into the compression chamber 53; at the same time, the push head hydraulic cylinder contracts and drives the push head 2 to move backward, so that the lower end of the push head 2 and the arc-shaped upper end of the rotating pressing plate 3 abut against each other to prevent the garbage from flowing out from the gap between the two. When the rotating pressing plate 3 rotates to a position perpendicular to the push head 2, the rotating pressing plate 3 stays at this position, and the anti-rebound hydraulic cylinder 62 drives the latch 61 to move inward to prevent the rotating pressing plate 3 from rotating in the opposite direction. Then the push head hydraulic cylinder is driven to extend to perform secondary compression on the garbage in the compression chamber 53. After the garbage is compressed and formed, the gate 4 is opened, and the push head hydraulic cylinder is driven to extend to push the garbage out from the discharge port; when the push head 2 moves to the discharge port, the hydraulic motor drives the rotating pressure plate 3 to continue to rotate counterclockwise through the reducer and return to its original position; the anti-rebound hydraulic cylinder 62 drives the latch 61 to move outward and return to its original position; and the push head 2 also moves forward to return to its original position, and the gate 4 is closed; this cycle is repeated until all the garbage compression work is completed.
