Method used

It adopts a chassis-guided recirculation structure and achieves pressure relief through the design of the guide pipe. When the pusher returns, the water in the kitchen waste in the rear return chamber is returned to the front compression chamber. Combined with the inclined guide plate and multiple guide pipes, the flow efficiency is improved and the waste overflow is prevented.

Benefits of technology

It improves the compression efficiency and operating speed of the garbage compressor, prevents garbage overflow, and enhances the utilization rate of the equipment.

Description

Technical Field

[0001] This utility model belongs to the field of mobile waste compression equipment, and specifically relates to a chassis guide return structure. Background Technology

[0002] A garbage compactor is a commonly used device for waste processing. It collects waste at collection stations and then transports it to waste treatment plants by hook-lift trucks. To improve the utilization rate of garbage compactors, a pusher is typically included to push and compress the waste. Current garbage compactors have the following drawbacks: food waste has a high water content, filling the rear chamber of the pusher with liquid components. This back pressure reduces the return speed, affecting compression efficiency and causing waste to easily accumulate and overflow at the feed inlet. Utility Model Content

[0003] The purpose of this invention is to provide a chassis-guided reflux structure, which adopts a flow guiding structure in the compression cavity and improves compression efficiency through a pressure relief design of the flow guiding pipe. During compression, the reflux is guided to avoid waste overflow.

[0004] The purpose of this utility model is achieved as follows: a chassis-guided return flow structure includes a chassis, a feeding port at the top of the chassis, a pusher that can move back and forth inside the chassis, a front compression chamber formed in front of the pusher inside the chassis, a rear return chamber formed behind the pusher inside the chassis, an inclined guide plate corresponding to the pusher inside the chassis, a plurality of connecting holes arranged along the length direction on the guide plate, a guide pipe corresponding to each connecting hole below the guide plate, and the lower end of the guide pipe corresponding to the rear return chamber.

[0005] When this mobile garbage compactor is in operation, garbage enters the housing through the feeding port. Then, a hydraulic cylinder drives the pusher head to reciprocate, compressing the garbage forward. The guide pipe employs a pressure relief design to unload pressure. When the pusher head moves to the rear return chamber, the moisture from the kitchen waste in the rear return chamber can flow back to the front compression chamber through the guide pipe. Compared with existing technologies, the advantages of this invention are: the use of a flow-guiding structure in the rear compression chamber, and the pressure relief design through the guide pipe, improves compression efficiency and operating speed; and the backflow guidance during compression prevents garbage overflow.

[0006] As a further improvement of this utility model, at least four guide tubes are provided, and each guide tube is equidistantly distributed along the length of the guide plate. Multiple guide tubes improve the flow guiding efficiency.

[0007] As a further improvement of this utility model, the guide tube is a square tube, the connecting hole is a square hole, and the guide tube is inclined.

[0008] As a further improvement of this utility model, a shielding cover is correspondingly provided above each connecting hole on the guide plate. The shielding cover has an opening at its front and includes an upper plate. Side plates extending downwards are provided on both the left and right sides of the upper plate. The rear parts of the upper plate and the side plates are fixed to the guide plate. The shielding cover serves to shield the guide pipe and prevent blockage.

[0009] As a further improvement of this utility model, a lower support plate and a rear baffle are provided corresponding to the guide plate. The guide plate, lower support plate, and rear baffle form a triangle. A through hole is provided on the lower support plate for each guide tube. The lower end of the guide tube passes through the corresponding through hole, and the upper end of the guide tube passes through the connecting hole. The rear baffle is fixed to the inner wall of the box, and the lower support plate is located above the pusher. The outer periphery of the guide tube is fixed to the inner wall of the connecting hole and the through hole. The guide tube can connect the rear return cavity to the top of the guide plate.

[0010] As a further improvement of this utility model, a number of drive cylinders are provided in the rear return cavity of the housing corresponding to the pusher head, and the working end of the drive cylinder is hinged to the pusher head. The drive cylinder drives the pusher head to move back and forth.

[0011] As a further improvement of this utility model, the container body is provided with an openable and closable door corresponding to the feeding port. After the door is opened, garbage can be thrown into the container body. Attached Figure Description
