Description

Technical Field

[0001] The present invention relates to the technical field of garbage compressors, and particularly to a ram head of a garbage compressor. Background Art

[0002] A garbage compressor is one of the main devices for realizing garbage compression and volume reduction, and is also the main processing device of a garbage transfer station. A garbage compressor is the main device of a garbage transfer station, and is a machine that compresses the collected garbage by a hydraulic system to reduce the volume of the garbage. However, when the existing technology compresses wet garbage or garbage containing moisture, a lot of sewage will be squeezed out. Some garbage compressors do not have a sewage discharge function, and the sewage will only be discharged from the compression seam of the compressor, which seriously affects the environment. There are also some compressors with sewage discharge holes. One is to set corresponding matrix drainage holes on the side wall of the compression chamber, but as the compression chamber decreases, the drainage holes will gradually decrease. The other is to set drainage holes on the bottom wall of the compression chamber, but as the garbage gradually becomes compact, the drainage holes will be squeezed and closed by the garbage more and more tightly, resulting in serious blockage of the drainage holes. Summary of the Invention

[0003] The purpose of the present invention is to solve the disadvantage of poor drainage performance of garbage compressors in the prior art, and to propose a ram head of a garbage compressor.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A ram head of a garbage compressor includes a ram head and a second hydraulic cylinder for driving the ram head to move. The ram head includes a plurality of first pressing plates and a plurality of second pressing plates. The plurality of first pressing plates and the plurality of second pressing plates are alternately distributed. The plurality of first pressing plates are fixedly connected to the piston rod of the second hydraulic cylinder through a second bracket. The first pressing plates are provided with a plurality of sewage holes, one end of each sewage hole communicates with the garbage compression chamber, and the other end communicates with the outside of the garbage compression chamber. A power compression assembly is installed on the second bracket, and the power compression assembly can drive the second pressing plates to protrude from the end face of the first pressing plates far away from the second hydraulic cylinder.

[0006] The plurality of second pressing plates are slidably connected to the first pressing plates. The power compression assembly includes a first hydraulic cylinder fixedly installed on the second bracket. A first bracket is fixedly installed at the end of the piston rod of the first hydraulic cylinder, and the first bracket is fixedly installed with a plurality of second pressing plates.

[0007] When the end of the second pressing plate far away from the first hydraulic cylinder is flush with the end of the first pressing plate far away from the second hydraulic cylinder, the second pressing plate abuts against the second bracket.

[0008] The thrust of the second hydraulic cylinder is greater than the thrust of the first hydraulic cylinder.

[0009] One end of the sewage hole away from the garbage compression chamber is connected with a sewage pump.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Referring to Figures 1-3 , a ram head of a garbage compressor includes a ram head 1 and a second hydraulic cylinder 4 for driving the movement of the ram head 1. The ram head 1 includes a plurality of first pressing plates 7 and a plurality of second pressing plates 8. The plurality of first pressing plates 7 and the plurality of second pressing plates 8 are alternately distributed. The plurality of first pressing plates 7 are fixedly connected to the piston rod of the second hydraulic cylinder 4 through the second bracket 5. The first pressing plate 7 is provided with a plurality of sewage holes 2. One end of the sewage hole 2 communicates with the garbage compression chamber, and the other end communicates with the outside of the garbage compression chamber. When compressing garbage, the sewage is squeezed out and discharged through the sewage holes of the first pressing plate 7. A power compression assembly is installed on the second bracket 5, and the power compression assembly can drive the second pressing plate 8 to protrude from the end face of the first pressing plate 7 away from the second hydraulic cylinder 4.

[0017] Drive the entire pressure head towards the garbage compression chamber through the second hydraulic cylinder 4, and compress the garbage inside the garbage compression chamber under the thrust of the pressure head. If it is a vertical garbage compressor, the downward movement of the pressure head compresses the garbage. If it is an in-ground horizontal garbage compressor, then the compression of the garbage is either to the left or to the right. The following description takes the vertical garbage compressor as an example. For instance, the entire compression process is positioned as mild compression (using one-third of the thrust of the second hydraulic cylinder 4), moderate compression (using two-thirds of the thrust of the second hydraulic cylinder 4), and heavy compression (using all of the thrust of the second hydraulic cylinder 4). When the device is actually working, first drive the entire pressure head 1 into the garbage compression chamber through the second hydraulic cylinder 4 to perform mild compression on the garbage. Due to the relatively small pressure during mild compression, the garbage is still relatively loose at this time, and the sealing force of the sewage hole blocked by the garbage is relatively small (this sealing force refers to the pressure exerted by the garbage to block the sewage hole when under pressure). Normal drainage can be carried out during garbage compression, and mild compression is also beneficial for forming a less dense garbage block inside the garbage compression chamber. During the transition from mild compression to moderate compression and from moderate compression to heavy compression, after moving a small distance each time, the second hydraulic cylinder 4 stops moving for a period of time. At this time, drive the second pressing plate 8 towards the inside of the garbage compression chamber through the power compression component, so that the compression surface of the pressure head 1 forms a shape in the form of a pulse diagram. Since the second pressing plate 8 moves downward and the first pressing plate 7 does not move, in this way, drive the garbage at the bottom of the first pressing plate 7 downward through the second pressing plate 8, reducing the sealing force of the sewage hole 2 at the bottom of the first pressing plate 7 or completely opening the sewage hole 2. Therefore, when the second pressing plate 8 moves downward, the sewage can drain more smoothly from the sewage hole 2. On the basis of ensuring that a single first pressing plate 7 and second pressing plate 8 meet the compression strength, arrange the first pressing plates 7 and second pressing plates 8 as many and as closely as possible in an alternating manner. Only in this way can the sewage hole 2 at the bottom of the first pressing plate 7 be better released when the second pressing plate 8 presses downward. When the second pressing plate 8 extends to the limit position or approaches the limit position, stop moving for a moment to allow the sewage to be discharged as much as possible under this extrusion force, and then retract the second pressing plate 8 to make the first pressing plate 7 and the second pressing plate 8 level again. Then start the second hydraulic cylinder 4 again to make the entire pressure head move downward a certain distance again, repeating the above steps until the first hydraulic cylinder 3 reaches the maximum pressure. When reaching heavy compression, make the first pressing plate 7 and the second pressing plate 8 level again, and use the second hydraulic cylinder 4 to perform the final compression of the entire pressure head. When compressing the garbage through this kind of pressure head, the smoothness of the sewage hole 2 can be better ensured, and the sewage in the compression chamber can be better discharged.

[0018] When the device is working, the entire compression movement of the pressure head should not be carried out when the pressure head is in an uneven state, because this can easily make the top surface of the garbage block uneven, and then the sewage holes will still be blocked. When the entire pressure head is flat and moves downward in compression, it can ensure that when the pressure head becomes uneven, the pressing force of the sewage holes is released and the sewage holes are better opened.

[0019] The pressure head of this device can be used together with the existing compression chamber drainage structure pointed out in the background technology. Just directly modify the existing pressure head into this device, which can not only reduce the modification cost, but also effectively improve the sewage discharge speed of the garbage compressor. And this device can also replace the pressure head of the garbage compressor without a drainage structure, making this kind of garbage compressor form a new type of garbage compressor with drainage function.

[0020] As a specific implementation of the power compression component, several second pressing plates 8 are slidably connected to the first pressing plate 7. The power compression component includes a first hydraulic cylinder 3 fixedly installed on the second bracket 5. The end of the piston rod of the first hydraulic cylinder 3 is fixedly installed with a first bracket 6, and the first bracket 6 is fixedly installed with a plurality of second pressing plates 8. The first hydraulic cylinder 3 drives the second pressing plates 8 to move downward or upward.

[0021] When the end of the second pressing plate 8 away from the first hydraulic cylinder 3 is flush with the end of the first pressing plate 7 away from the second hydraulic cylinder 4, the second pressing plate 8 abuts against the second bracket 5. Refer to Figure 1 , when the second hydraulic cylinder 4 pushes the pressure head downward, the top of the second pressing plate 8 abuts against the second bracket 5, so that the first hydraulic cylinder 3 will not burst.

[0022] As an implementation, the thrust of the second hydraulic cylinder 4 is greater than the thrust of the first hydraulic cylinder 3.

[0023] In order to better discharge the sewage in the compression chamber, a sewage pump is connected to the end of the sewage hole 2 away from the garbage compression chamber.

[0024] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes to obtain technical solutions, concepts, and designs, which should all be covered by the protection scope of the present invention.
