[0029] Reference Figure 1 A material discharging door assembly includes: a chassis 100, a tool spindle 200, a door body 300 and a driving device 400. The chassis 100 is provided with an operating area 150; the tool spindle 200 is rotatably installed in the chassis 100, and the tool spindle 200 can drive the tool to crush and cut the material in the operating area 150; the door body 300 is movably installed in the chassis 100, and the door body 300 can move close to the operating area 150 and shield the operating area 150, and the door body 300 can move away from the operating area 150 and make the operating area 150 open; the driving device 400 is installed in the chassis 100, and the driving device 400 is connected to the door body 300 and can drive it to move close to or away from the operating area 150. After the garbage material is discharged into the operating area 150 of the chassis 100, the tool spindle 200 can drive the crushing tool to rotate, thereby achieving the effect of crushing and cutting the garbage material. When the crushing operation is in progress, the door body 300 will remain in the state of shielding the working area 150, so that the uncrushed garbage materials cannot escape from the working area 150 by themselves, thereby ensuring that they can be crushed and cut smoothly and accurately. After the crushing operation is completed, the driving device 400 can drive the door body 300 to move away from the chassis 100, so that the staff can directly process the crushed materials in the working area 150, so that the effect of cleaning the materials in the chassis 100 can be achieved more simply and efficiently, thereby reducing the time for operators to maintain the equipment and effectively improving production efficiency.

[0030] In certain embodiments, reference Figure 3One end of the door body 300 is hinged to the chassis 100, and the driving device 400 is connected to the other end of the door body 300 and can drive it to rotate. The door body 300 and the chassis 100 are hinged, so no matter how the door body 300 moves, the door body 300 will always have a part connected to the chassis 100, thereby effectively avoiding the problem of the door body 300 being misplaced and falling off, and making the relative movement between the door body 300 and the chassis 100 more stable and reliable.

[0031] It is conceivable that the door body 300 may also be slidably mounted on the chassis 100 and slide away from the working area 150. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0032] In certain embodiments, reference Figure 3 The driving device 400 includes a hydraulic cylinder 450 installed on the chassis 100. The hydraulic cylinder 450 is connected to the end of the door body 300 and can drive it to rotate. After the hydraulic cylinder 450 is started, the end of the door body 300 can be displaced by the hydraulic force, so that the door body 300 rotates and swings around the connection point between it and the chassis 100, thereby directly and effectively achieving the effect of driving the door body 300 to move relative to the working area 150.

[0033] It is conceivable that the driving device 400 may also be composed of other components, such as being connected to the door body 300 via an electric cylinder. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0034] In certain embodiments, reference Figure 3 The hydraulic cylinder 450 includes a cylinder body 410 and a piston rod 430, wherein the piston rod 430 is movably installed in the cylinder body 410; the cylinder body 410 is hinged to the chassis 100, and the end of the piston rod 430 is hinged to the door body 300. After the piston rod 430 is driven by hydraulic power in the cylinder body 410, the piston rod 430 can move and drive the door body 300 to rotate, thereby directly and effectively driving the door body 300 to open and close, thereby facilitating the cleaning of materials in the working area 150. In addition, the cylinder body 410 and the piston rod 430 are both hinged, so that the direction of the door body 300 can be automatically adjusted when the door body 300 rotates, and the problem of jamming can be avoided.

[0035] In certain embodiments, reference Figure 3The working area 150 has a discharge port 155, and the tool spindle 200 and the discharge port 155 are respectively installed on both sides of the chassis 100; the door body 300 is movably installed at the discharge port 155 and can cover the discharge port 155. The discharge port 155 allows the materials in the working area 150 to be accurately discharged, so that they are conveniently discharged outside the working area 150; the position setting of the tool spindle 200 and the discharge port 155 can make the tool spindle 200 and the door body 300 respectively located on both sides of the chassis 100, thereby effectively avoiding the problem of mutual interference between the two during movement, thereby ensuring that both can operate smoothly.

[0036] In certain embodiments, reference Figure 3 The door body 300 has a receiving surface 370; when the door body 300 shields the working area 150, the receiving surface 370 is located below the discharge port 155; when the door body 300 rotates away from the discharge port 155, the receiving surface 370 can be adjusted to face the outer side and lower side of the chassis 100. When the material is still being crushed and cut in the working area 150, the door body 300 is located at the discharge port 155 and shields the discharge port 155. At this time, the receiving surface 370 is located below the discharge port 155 and can receive the material that has not been completely crushed, thereby preventing the material from escaping from the working area 150 before being completely crushed. When the door 300 is opened and the working area 150 is cleaned, the receiving surface 370 will face the outer side and lower side of the chassis 100, so that the material on the receiving surface 370 will slide off the receiving surface 370 smoothly, thereby effectively avoiding the problem of material being retained on the receiving surface 370, and ensuring that the material can be smoothly discharged outside the working area 150.

[0037] In certain embodiments, reference Figure 3 The receiving surface 370 is an arc-shaped curved surface and connects two adjacent side portions of the door body 300. The curved receiving surface 370 allows the material retained on the receiving surface 370 to slide off the receiving surface 370 quickly and smoothly, thereby preventing the material from being retained on the door body 300 continuously, and can effectively ensure that the material on the door body 300 is gathered at the lower portion of the door body 300, so that operations such as cleaning the door body 300 can be carried out more smoothly.

[0038] In certain embodiments, reference Figure 2 There are multiple hydraulic cylinders 450, which are respectively located on both sides of the chassis 100, and both sides of the door body 300 are connected to the hydraulic cylinders 450. Multiple hydraulic cylinders 450 can drive the door body 300 evenly on both sides of the chassis 100, so that the door body 300 can move more stably, thereby avoiding the problem of imbalance of the door body 300 during movement.

[0039] In certain embodiments, reference Figure 3The tool spindle 200 is provided with a plurality of hob areas 250, and the door body 300 includes a plurality of discharge areas 350, and the discharge areas 350 correspond to the hob areas 250 one by one. The plurality of hob areas 250 can crush and cut the materials respectively, so that the materials can be reduced to a small volume. The discharge area 350 can screen the crushed materials, and the materials can only pass through the corresponding discharge area 350 after being crushed to the size of the hob area 250, so that the size of the discharged materials can be effectively ensured.

[0040] The second aspect of the utility model provides an embodiment of a crusher, including the above-mentioned discharge door assembly. After the garbage material is discharged into the working area 150 of the chassis 100, the tool spindle 200 can drive the crushing tool to rotate, thereby achieving the effect of crushing and cutting the garbage material. When the crushing operation is in progress, the door body 300 will remain in a state of shielding the working area 150, so that the uncrushed garbage material cannot escape from the working area 150 by itself, thereby ensuring that it can be crushed and cut smoothly and accurately. After the crushing operation is completed, the drive device 400 can drive the door body 300 to move away from the chassis 100, so that the staff can directly process the crushed materials in the working area 150, so that the effect of cleaning the materials in the chassis 100 can be achieved more simply and efficiently, thereby reducing the time for operators to maintain equipment and effectively improving production efficiency.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
