Description

Technical Field

[0001] This utility model relates to the field of hydraulic baling machinery technology, and in particular to an improved hydraulic baling machine. Background Technology

[0002] A hydraulic baler is a device that uses hydraulic technology to compress materials. It is mainly used to compress loose metal scrap into compact bales, reducing storage and transportation space, improving efficiency, and lowering costs.

[0003] In the existing technology, the pushing assembly or pushing mechanism of traditional balers is not stable enough. In particular, the main pusher cylinder transmits power through welded stiffeners, which may lead to stress concentration and tearing. The pusher driven by a single cylinder is prone to uneven load, which affects the compression molding quality. In addition, the inner wall of the material box of traditional balers is severely worn, and the wear plates of existing equipment are mostly fixed by welding, making replacement and maintenance difficult. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an improved hydraulic baler. The main push assembly adopts a pull-column structure, with the initial state of the main push head set outside the material box, increasing the space inside the material box and enabling the compression of larger bales. In addition, the pull-column structure directly bears the thrust of the hydraulic cylinder, improving the stress performance and reducing the risk of tearing. This solves the technical problem that the hydraulic cylinder of the main push head transmits power through welded stiffeners, which may lead to stress concentration and tearing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an improved hydraulic baler, comprising a material box, a receiving hopper installed on the material box, a main push assembly installed on one side of the main viewing surface of the material box, and a side push assembly installed on the right side of the material box, wherein the axes of the main push assembly and the side push assembly are perpendicular to each other;

[0008] The main push assembly includes a main push head cylinder. A support base is installed at the end of the main push head cylinder. A circular hole is opened in the center of the support base for the piston rod of the main push head cylinder to extend and retract. Pull posts are installed on the four corners of the inner side of the support base. The other end of each pull post is installed on the opposite side of the material box. The piston rod of the main push head cylinder is connected to the top of the main push head cylinder. The side of the main push head in the initial state is flush with the outer side of the material box.

[0009] Furthermore, each surface inside the material box is equipped with a prefabricated wear-resistant plate, which is processed into an undulating structure.

[0010] Furthermore, the assembled wear-resistant plate is made of high-chromium cast iron and can be detachably installed on the inner wall of the hopper via a dovetail groove structure.

[0011] Furthermore, the side push assembly includes a side push head cylinder mounted on the side of the material box, with a side push head connected to the top of the piston rod of the side push head cylinder, and the side push head is placed inside the material box.

[0012] Furthermore, there are two side push head cylinders, which are symmetrically installed on the side of the material box, and the piston rods of the two side push head cylinders are connected to the side push head together.

[0013] Furthermore, the piston rod tip of the main pusher cylinder is connected to the main pusher via a coupling.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an improved hydraulic baler, which has the following features:

[0016] Beneficial effects:

[0017] 1. The main push assembly of this improved hydraulic baler adopts a pull column structure, which aligns the side of the main push head in its initial state with the outer side of the material box. This means that the initial state of the main push head is set outside the material box, increasing the space inside the material box and allowing for the compression of larger bales. In addition, the pull column structure directly bears the thrust of the hydraulic cylinder, improving the stress performance and reducing the risk of tearing.

[0018] 2. The inner surface of the material box of this improved hydraulic baler is equipped with assembled wear-resistant plates with an undulating structure to ensure that it will not jam when dealing with waste materials such as thin plates, thereby improving work efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-2 An improved hydraulic baler includes a material box 1 with a receiving hopper 2 installed on it. Assembled wear-resistant plates 5 are installed on each surface inside the material box 1, with the plates having an undulating structure. The plates are made of high-chromium cast iron and are detachably mounted to the inner wall of the material box 1 via a dovetail groove structure. A main push assembly 3 is installed on one side of the main viewing surface of the material box 1, and a side push assembly 4 is installed on the right side. The axes of the main push assembly 3 and the side push assembly 4 are perpendicular to each other. The main push assembly 3 includes a main push head cylinder 301, with a support base 302 installed at the end of the cylinder. A circular hole is provided in the center of the support base 302 for the piston rod of the main push head cylinder 301 to extend and retract. The four corners of the inner side of the support base 302... Each of the four components is equipped with a pull column 303, and the other end of each pull column 303 is installed on the opposite surface of the material box 1. The piston rod of the main push head cylinder 301 is connected to the top of the main push head 304. The side of the main push head 304 is flush with the outer side of the material box 1 in its initial state. The piston rod of the main push head cylinder 301 is connected to the main push head 304 through a coupling 305. The side push assembly 4 includes a side push head cylinder 401 installed on the side of the material box 1. The piston rod of the side push head cylinder 401 is connected to the top of the side push head 402. The side push head 402 is placed inside the material box 1. There are two side push head cylinders 401. The two side push head cylinders 401 are symmetrically installed on the side of the material box 1. The piston rods of the two side push head cylinders 401 are connected to the side push head 402.

[0026] The working principle of the above embodiments is as follows:

[0027] In use, waste material is fed from receiving hopper 2 into material box 1 via conveyor. First, the side push head 402 is pushed by the side push head cylinder 401 to compress the waste material laterally. Then, the main push head 304 is pushed by the main push head cylinder 301 to compress the waste material longitudinally, finally forming a regular cube block of 1000×1000mm, which is then pushed out of material box 1 for recycling.

[0028] In the above process, the main push assembly 3 adopts a pull-column structure, which aligns the side of the main push head 304 in its initial state with the outer side of the material box 1. This means the initial state of the main push head 304 is set outside the material box 1, increasing the space inside the box and allowing for the compression of larger bales. Furthermore, the pull-column structure directly bears the thrust of the hydraulic cylinder, improving stress resistance and reducing the risk of tearing. The inner surface of the material box 1 is fitted with assembled wear-resistant plates 5, featuring an undulating structure to ensure that it does not jam when handling thin plates or other waste materials, thus improving work efficiency.
