Description

Technical Field

[0001] The utility model relates to the technical field of shredders, in particular to an auxiliary material pressing control structure for a shredder. Background Art

[0002] The modernization of industry has led to the expansion of enterprise scale. The expansion of scale requires high-efficiency, high-capacity and energy-saving equipment. The same is true for garbage sorting and treatment. High-efficiency and high-quality classification and treatment of garbage can improve social benefits, bring economic benefits, and achieve environmental protection goals. Most of the existing garbage treatment uses shredders to shred the transferred garbage, and then sort and treat it in a targeted manner.

[0003] The existing shredder needs to squeeze the material through a pressure plate when shredding to ensure that the material contacts the shredding blades for shredding. The existing pressure plate cannot fit the inner wall of the hopper when pressing the material, and material debris may splash out during shredding, which poses a certain safety hazard. In addition, most of the existing pressure plates can only move linearly up and down and cannot move away from the hopper, which may block the material when loading. Utility Model Content

[0004] The purpose of the utility model is to provide a shredder auxiliary material pressing control structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a shredder auxiliary pressing control structure, comprising a shredding bin, a hopper is provided on the top of the shredding bin, a pressing plate is provided above the hopper, the front and rear ends of the pressing plate are hingedly installed with a first inclined plate, and both sides of the pressing plate are hingedly installed with a second inclined plate, and four flexible protective films are jointly installed between the first inclined plate and the second inclined plate at the four corners of the pressing plate, two stabilizing columns are provided at the top of the pressing plate, the outer surfaces of the two stabilizing columns are jointly slidably connected to a support plate, the tops of the two stabilizing columns are jointly connected to a displacement plate, and a hydraulic rod is jointly connected between the bottom end of the displacement plate and the top end of the support plate, a support column is provided at the rear bottom end of the support plate, the bottom end of the support column is sleeved with a fixer, and an auxiliary frame is provided on the outer surface of the support column above the fixer.

[0006] Preferably, the tops of the two first inclined plates and the two second inclined plates are both provided with an articulated frame, and four lifting frames are provided at the top of the pressing plate near the edge, and the tops of the four articulated frames are hingedly installed with resetters between the tops of the corresponding lifting frames, and the resetter contains a telescopic rod and a spring located on the outer surface of the telescopic rod. Since the hopper is an inverted square cone, when the pressing plate moves toward the inside of the hopper, the first inclined plate and the second inclined plate will be squeezed by the inner wall of the hopper to flip upward, and the spring contained in the resetter will be squeezed and at the same time, a thrust will be applied to the tops of the corresponding first and second inclined plates, so that the first and second inclined plates fit the inner wall of the hopper, thereby avoiding debris splashing out of the hopper and injuring nearby staff during the shredding operation.

[0007] Preferably, a limiting column is provided at the bottom end of the auxiliary frame, and an arc-shaped limiting groove is provided at the top of the fixer. The limiting column extends to the arc-shaped limiting groove, and the arc-shaped groove limits the limiting column, so that the rotation range of the auxiliary frame is limited, ensuring that the support column can drive the pressing plate to rotate to the top of the hopper for pressing or to the side above the hopper for loading.

[0008] Preferably, a through hole is provided on one side of the fixer, a locking column is provided on one side of the through hole, and an electric push rod is provided at one end of the locking column. The electric push rod drives the fixer to perform linear movement. When the limit column is driven to one end of the arc-shaped limit groove close to the through hole, the electric push rod pushes the locking column into the inside of the fixer, blocking the limit column so that the limit column cannot move. When the electric push rod pulls the locking column out of the inside of the fixer, the limit column is released, and the support column can rotate at this time.

[0009] Preferably, a base is provided at the bottom end of the shredding bin, and the base supports the shredding bin to make the shredder more stable.

[0010] Preferably, the bottom end of the holder is fixedly mounted on the top end of the base, and the holder is fixed so that the support column will not fall over.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The auxiliary material pressing control structure of this shredder is used in conjunction with the material pressing plate and the first inclined plate hingedly installed at the front and rear ends of the material pressing plate, and the second inclined plates hingedly installed on both sides of the material pressing plate. When pressing the material, the first inclined plate and the second inclined plate will be squeezed upward by the inner wall of the hopper to make the first inclined plate and the second inclined plate fit the inner wall of the hopper, thereby preventing debris from splashing out of the hopper and injuring nearby workers during the shredding operation.

[0013] 2. The auxiliary pressing control structure of this shredder is equipped with an auxiliary frame on the outer surface of the support column. When the limit column set at the bottom of the auxiliary frame rotates to a predetermined position, it can be limited by the locking column, so that the support column cannot rotate, ensuring that the pressing plate will not move when pressing the material.

[0021] like Figures 1 to 4As shown, this embodiment is a shredder auxiliary pressing control structure, including a shredding bin 1, a hopper 2 is provided on the top of the shredding bin 1, a pressing plate 5 is provided above the hopper 2, the front and rear ends of the pressing plate 5 are hingedly mounted with a first inclined plate 4, and both sides of the pressing plate 5 are hingedly mounted with a second inclined plate 11, and four flexible protective films 16 are installed between the first inclined plate 4 and the second inclined plate 11 at the four corners of the pressing plate 5. The flexible protective film 16 is made of nylon with high strength and good flexibility. When the pressing plate 5 moves toward the inside of the hopper 2, the first inclined plate 4 and the second inclined plate 11 will be squeezed by the inner wall of the hopper 2 to flip upward and fit with the inner wall of the hopper 2 to prevent debris from splashing out of the hopper 2 during the shredding operation and injuring nearby staff. Two stabilizing columns 7 are provided on the top of the pressing plate 5. The outer surfaces of the two stabilizing columns 7 are slidably connected with a support plate 9, and the tops of the two stabilizing columns 7 are connected with a displacement plate 8. A hydraulic rod 6 is connected between the bottom end of the displacement plate 8 and the top of the support plate 9. The two stabilizing columns 7 support the pressing plate 5, and the hydraulic rod 6 can drive the pressing plate 5 to perform linear movement up and down, so that the pressing plate 5 can be extended into the interior of the hopper 2 to press the material, or it can leave the interior of the hopper 2 without affecting the loading of the material. A support column 10 is provided at the rear bottom end of the support plate 9, and a fixer 22 is sleeved on the bottom end of the support column 10. An auxiliary frame 12 is provided on the outer surface of the support column 10 above the fixer 22, and the support column 10 and the fixer 22 are rotatably connected. When the pressing plate 5 leaves the interior of the hopper 2, the support column 10 is rotated so that the pressing plate 5 is driven away from the top of the hopper 2, which is convenient for putting the material into the interior of the hopper 2.

[0022] Specifically, the tops of the two first inclined plates 4 and the two second inclined plates 11 are each provided with an articulated frame 14, and four lifting frames 13 are provided near the edge of the top of the pressing plate 5. The tops of the four articulated frames 14 are respectively hingedly installed with resetters 15 between the tops of the corresponding lifting frames 13. The resetter 15 contains a telescopic rod and a spring located on the outer surface of the telescopic rod. Since the hopper 2 is an inverted square cone, when the pressing plate 5 moves toward the inside of the hopper 2, the first inclined plate 4 and the second inclined plate 11 will be squeezed by the inner wall of the hopper 2 to flip upward, and the spring contained in the resetter 15 will be squeezed, and at the same time, a thrust will be applied to the tops of the corresponding first inclined plate 4 and second inclined plate 11, so that the first inclined plate 4 and the second inclined plate 11 fit the inner wall of the hopper 2, thereby preventing debris from splashing out of the hopper 2 during the shredding operation to injure nearby staff.

[0023] Furthermore, a limiting column 19 is provided at the bottom end of the auxiliary frame 12, and an arc-shaped limiting groove 20 is provided on the top of the fixer 22. The limiting column 19 extends to the arc-shaped limiting groove 20, and the arc-shaped limiting groove 20 limits the limiting column 19, so that the rotation range of the auxiliary frame 12 is limited, ensuring that the support column 10 can drive the pressing plate 5 to rotate to the top of the hopper 2 for pressing or to the side above the hopper 2 for loading.

[0024] Furthermore, a through hole 17 is provided on one side of the fixer 22, and a locking column 18 is provided on one side of the through hole 17. An electric push rod 21 is provided at one end of the locking column 18. The electric push rod 21 drives the fixer 22 to perform linear movement. When the limit column 19 is driven to one end of the arc-shaped limit groove 20 located near the through hole 17, the electric push rod 21 pushes the locking column 18 into the inside of the fixer 22, blocking the limit column 19 so that the limit column 19 cannot move. When the electric push rod 21 pulls the locking column 18 out of the inside of the fixer 22, the limit column 19 is released, and the support column 10 can rotate at this time.

[0025] Furthermore, a base 3 is provided at the bottom end of the shredding bin 1, and the base 3 supports the shredding bin 1 to make the shredder more stable.

[0026] Furthermore, the bottom end of the fixer 22 is fixedly mounted on the top end of the base 3 , and the fixer 22 is fixed so that the support column 10 will not fall over.

[0027] The method of use of this embodiment is as follows: when the pressing plate 5 performs the pressing operation, the hydraulic rod 6 can drive the pressing plate 5 to perform linear movement downward. When the pressing plate 5 moves toward the inside of the hopper 2, the first inclined plate 4 and the second inclined plate 11 will be squeezed by the inner wall of the hopper 2 to flip upward, and the spring contained in the resetter 15 will be squeezed. At the same time, a thrust is applied to the top of the corresponding first inclined plate 4 and the second inclined plate 11, so that the first inclined plate 4 and the second inclined plate 11 are in contact with the inner wall of the hopper 2 to prevent debris from splashing out of the hopper 2 and injuring nearby workers during the shredding operation. After the pressing is completed, the hydraulic rod 6 pulls the pressing plate 5 out of the inside of the hopper 2, and then After the electric push rod 21 pulls the locking column 18 out of the fixture 22, the limit column 19 is released, and the support column 10 is rotated by the auxiliary frame 12 to drive the pressing plate 5 away from the top of the hopper 2, which is convenient for the staff to put the material into the hopper 2. After the material is put in, the auxiliary frame 12 is rotated in the opposite direction to drive the pressing plate 5 to be located above the hopper 2 through the column. The limit column 19 is driven to be located at one end of the arc-shaped limit groove 20 near the through hole 17, and then the locking column 18 is pushed into the inside of the fixture 22 by the electric push rod 21, blocking the limit column 19, so that the limit column 19 cannot move, ensuring that the pressing plate 5 will not be displaced when pressing the material.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
