Description

Technical Field

[0001] The present application relates to a garbage compression device. Background Art

[0002] With the progress and development of society, people's living standards are improving day by day. A large amount of material consumption, while enriching life, also generates a steady stream of garbage. Urban garbage management often involves setting up garbage bins in each residential area, where people put their domestic garbage into the garbage bins, and then garbage trucks regularly go to various garbage collection points to collect the garbage in the garbage bins.

[0003] In order to improve the existing environmental sanitation conditions and achieve the goal of "energy conservation and emission reduction", it is necessary to seek an environmentally friendly, efficient and economical way to transport domestic waste. In this context, garbage compression equipment has been widely used and developed rapidly. Garbage compression equipment is used to move the garbage collected by garbage trucks into large boxes by shoveling and other means and compress the garbage into a smaller volume for centralized transportation. In order to prevent the garbage from escaping, the garbage is usually put into the garbage compression equipment by top feeding. During the top feeding, the garbage is gathered through a fixed hopper and falls into the compression chamber of the garbage compression equipment.

[0004] The box of the garbage compression device is transported by a transport vehicle, so its position relative to the hopper is different each time the material is fed. This will cause the garbage to spill outside the garbage compression device when the position deviation between the compression chamber of the garbage compression device and the hopper is large. The method for solving the above problem in the prior art is usually to set four independent soft rubber baffles between the hopper and the device to surround the discharge port of the hopper. In this solution, there is a gap between the mobile device and the soft rubber baffle to ensure that the hopper does not scratch the box when the box of the garbage compression device moves. The position of the garbage compression device is usually repeatedly adjusted to ensure that the compression chamber of the garbage compression device is within an acceptable position range below the hopper, which is usually small. This is time-consuming and labor-intensive, and still cannot avoid the risk of garbage (especially light garbage and dust) falling into the garbage compression device being rebounded to the outside of the garbage compression device due to excessive garbage in the compression chamber of the garbage compression device. Summary of the invention

[0005] In order to solve the defects in the prior art, a garbage compression device is proposed to ensure that garbage will not be spilled outside the garbage compression device when feeding when there is a large position deviation between the garbage compression device and the hopper, and to ensure that garbage will not be rebounded to the outside of the garbage compression device due to excessive garbage in the compression chamber of the garbage compression device.

[0006] A garbage compression device comprises: a box body, a rear cover, which is arranged at the rear end of the box body, and a top cover, which is arranged on the top of the box body, characterized in that the garbage compression device comprises a hopper and a sealing ring, wherein the hopper is arranged outside the box body and fixed on an immovable bracket, and the sealing ring is arranged at the lower end of the hopper, wherein the side of the hopper is provided with an actuating device, a position sensor for sensing the position of the box body, and a retractable control rod pivotally connected to the hopper via the actuating device, and wherein the actuating device is configured to control the retraction and pivoting of the control rod according to the position of the box body.

[0007] According to an optional embodiment, the box body includes: a movable wheel arranged at the lower part of the box body for adjusting its position, a feeding port arranged at the top of the box body, a compression chamber arranged below the feeding port, a filling chamber engaged with the compression chamber, a pressing port arranged at the end of the compression chamber engaged with the filling chamber and communicating with the filling chamber, a compressor arranged in the compression chamber, wherein the compressor is configured to compress garbage received from the feeding port and push the compressed garbage into the filling chamber through the pressing port, and a discharge port arranged at the end of the filling chamber away from the compression chamber and used to discharge the compressed garbage.

[0008] According to an optional embodiment, the rear cover is hinged above the discharge opening of the box body in a manner allowing it to pivot around the box body.

[0009] According to an optional embodiment, the box body is provided with locking hooks around the rear cover, and the locking hooks cooperate with locking pins provided on the rear cover in a manner to prevent the rear cover from opening.

[0010] According to an optional embodiment, the top cover is configured to slide along the top of the box body between a first position and a second position, wherein the feeding port of the box body is opened in the first position and the feeding port of the box body is closed in the second position.

[0011] According to an optional embodiment, a hydraulic mechanism for driving the top cover is provided on the box body.

[0012] According to an optional embodiment, the sealing ring is made of a flexible material, an upper end of which is engaged to the outer periphery of the lower end of the hopper, and a lower end of which is engaged with the lower end of the control rod.

[0013] According to an optional embodiment, a plurality of control levers are provided on the hopper, the plurality of control levers are respectively provided on different sides of the hopper, and each of the plurality of control levers is pivotably connected to the hopper via a corresponding actuating device.

[0014] According to an optional embodiment, the actuation device is configured to control the extension and pivoting of each of the plurality of control rods.

[0015] According to an optional embodiment, a lower end of the sealing ring is engaged with a lower end of each of the plurality of control rods.

[0016] With the garbage compression device of the present application, garbage is put into the compression chamber of the garbage compression device from the hopper via the sealing ring connected between the hopper and the feeding port of the garbage compression device, so as to prevent the garbage from being rebounded to the outside of the garbage compression device due to excessive garbage in the compression chamber of the garbage compression device. Since the lower end of the sealing ring can move in one or more directions, in the case of a large positional deviation between the garbage compression device and the hopper, the lower end of the sealing ring will move to a position where it can engage with the feeding port of the garbage compression device, so that the garbage will not spill outside the garbage compression device when feeding.
