Description

Technical Field

[0001] The utility model belongs to the technical field of material crushing, and specifically provides a mobile crusher. Background Art

[0002] With the continuous development of garbage disposal technology, mobile material crushers that can be towed by a tractor or transported to different locations by a transport vehicle have gradually become common equipment in the garbage disposal field.

[0003] In the related technical solution, a traveling wheel is arranged at the bottom of the mobile crusher, and a crushing assembly and a feeding assembly in the form of a hopper are arranged inside the crusher. The hopper generally includes a bottom plate tilted downward to align with the crushing assembly and a side plate surrounding the bottom plate. The tilt angle of the bottom plate (i.e., the angle between the bottom plate and the horizontal plane) here will affect the supply speed of the entire material to the crushing assembly. Specifically, a large tilt angle value of the bottom plate will make the feeding speed of the bottom plate fast, and a small tilt angle value of the bottom plate will make the feeding speed of the bottom plate slow.

[0004] The inventors learned that the upper hopper of the prior art is generally an integrated structure with a bottom plate and a side plate fixed. When the angle of the bottom plate needs to be adjusted, the entire upper hopper needs to be rotated synchronously, which easily causes a large gap between the hopper and the frame and crushing assembly of the crusher, and thus easily accumulates garbage in the gap. Similarly, when the entire upper hopper needs to be driven to rotate, a driving part with large power and size needs to be pre-installed at the crusher, which is not convenient for achieving lightweight design of the crusher and energy saving. Utility Model Content

[0005] The purpose of the utility model is to provide a mobile crusher which can solve at least one of the above technical problems.

[0006] In order to solve the above-mentioned problems in the prior art, one or more embodiments of the utility model provide a mobile crusher, including a frame, a walking wheel is installed at the bottom of the frame, a crushing assembly for crushing materials and a feeding assembly for feeding materials to the crushing assembly are installed on the frame, the feeding assembly includes an upper hopper, the upper hopper includes two side plates arranged opposite to each other and a bottom plate arranged between the two side plates, the side plates are fixed to the frame, one end of the bottom plate is close to the crushing assembly and is rotatably connected to the frame, the other end of the bottom plate is a free end and the free end extends in an inclined upward direction, a driving assembly is installed between the bottom plate and the frame, and the driving assembly can drive the bottom plate to rotate relative to the frame to change the angle between the bottom plate and the horizontal plane.

[0007] Beneficial effects of one or more of the above technical solutions:

[0008] Compared with the upper hopper of the prior art that adopts an integrated structure, the upper hopper in this solution is formed by a combination of a bottom plate and two side plates. One end of the bottom plate is close to the crushing assembly and is rotatably connected to the frame, and the other end of the bottom plate is a free end and extends in an inclined upward direction. A driving assembly is installed between the bottom plate and the frame, so that the bottom plate can rotate relative to the frame to change the angle between the bottom plate and the horizontal plane. This setting of the present solution allows the bottom plate to rotate independently and thus change the sliding speed of the material on the bottom plate. During the rotation of the bottom plate, there is no need to adjust the position of the side plates, which can reduce the probability of the bottom plate rotating and interfering with the frame and the crushing assembly, and it is not easy to generate a gap between the upper hopper and the bottom plate for accumulating dirt. In addition, only the angle of the bottom plate is adjusted to fix the position of the side plates, which can reduce the power required by the drive assembly and the product size.

[0020] Specifically, the frame 1 in this embodiment includes a plurality of frame bars, the frame bars include horizontally arranged cross bars and longitudinal bars and vertically arranged upright bars, and the cross bars, longitudinal bars and upright bars are vertically arranged in pairs. In order to achieve the crushing component 4 and dustproof effects, this embodiment also includes a shell 2, which is detachably fixed to the outside of the entire crusher. More specifically, the shell 2 here is composed of a plurality of flat protective plates.

[0021] In order to realize the mobile function of the crusher, the frame 1 has a front-to-back direction, and the crushing assembly 4 and the feeding assembly 5 are arranged on both sides of the frame 1 along the front-to-back direction. The travel wheel is only arranged on one side along the front-to-back direction, and a hook 12 for traction is arranged on the other side of the frame 1 away from the travel wheel. The hook 12 is used to hook a traction vehicle, and then the traction vehicle drives the entire crusher to move. In some other embodiments, travel wheels can be arranged on both sides of the front and back of the frame 1, and the number of travel wheels can be set by those skilled in the art.

[0022] In this embodiment, the upper end of the crushing assembly 4 is open, and the side of the crushing assembly 4 near the feeding assembly 5 along the front-back direction is connected to the side of the upper hopper. Specifically, no partition or side plate 52 is provided at the position where the upper hopper and the crushing assembly 4 are connected.

[0023] For more details, see Figure 5 The bottom plate 51 includes a plate body and a rib plate located on the bottom surface of the plate body to strengthen the bottom plate 51. The driving assembly adopts an electric push rod or a hydraulic push rod. Taking the electric push rod 512 as an example, the housing of the electric push rod 512 is rotatably connected to the frame 1, and the end of the driving rod of the electric push rod is rotatably connected to the rib plate. When the electric push rod is extended or retracted, the electric push rod drives the rib plate and the entire bottom plate 51 to rotate around one end of the electric push rod close to the crushing assembly 4.

[0024] More specifically, a rotating seat 511 is provided on the bottom plate 51 , and a mounting seat 11 is provided on the frame 1 . The rotating seat 511 and the mounting seat 11 are rotatably connected via a rotating shaft.

When the second lower hopper 7 is full of crushed materials, the electric push rod 9 pushes the first lower hopper 6 to move directly below the crushing assembly, and the second lower hopper 7 is pushed out of the frame 1 from the outlet, so that the empty first lower hopper 6 can continuously receive the falling materials.

[0031] In this embodiment, a horizontal push mechanism is provided at the storage station, and the horizontal push mechanism is used to apply a thrust to the lower hopper toward the outlet 3. In this embodiment, the horizontal push mechanism includes an electric push rod. In some other embodiments, the horizontal push mechanism can also use a hydraulic cylinder or a linear motor.
