DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4, an automatic unloading mechanism of a shearing machine, including a conveying device 1, the conveying device 1 is composed of components such as a driving motor, a conveying roller and a conveying belt, which is a prior art product. As shown in the figure, it has an inclined section to facilitate the automatic unloading operation of the material processed by the shearing machine. Since it is a prior art product, this scheme does not describe it in detail. This scheme is attached Figure 1 It is only a schematic diagram of the structure, and the specific structure can be referred to the existing technology.

[0022] A support frame 2 is provided under the conveying equipment 1, and two openings 4 are provided on the support frame 2. Lifting screws 5 are rotatably provided in the two openings 4, and a lifting block 7 is provided on the threaded sleeve of the lifting screw 5. A transmission cavity is provided in the support frame 2, and a transmission shaft 11 is provided in the transmission cavity. A driving motor connected to the transmission shaft 11 is provided outside the support frame 2. The driving motor is arranged outside for easy disassembly, assembly and maintenance, etc., while ensuring that it has a good heat dissipation environment.

[0023] The ends of the two lifting screws 5 extend into the transmission cavity and are connected to the transmission shaft 11 through a rotating mechanism. A collecting trough 3 is provided under the conveying equipment 1, and a scraper 10 is provided on the collecting trough 3. Extrusion grooves 14 are provided on the outer walls on both sides of the collecting trough 3. A positioning block 15 is provided in the extrusion groove 14 through an extrusion mechanism, and an installation channel 9 corresponding to the positioning block 15 is provided on the lifting block 7.

[0024] The rotating mechanism includes a driving gear 12 arranged on the outer wall of the transmission shaft 11, and a transmission gear 13 is provided at the end of the lifting screw 5. The driving gear 12 is meshed with the transmission gear 13. As shown in the figure, the driving gear 12 and the transmission gear 13 are both bevel gears, which cooperate with the transmission shaft 11 to realize the power transmission of the driving motor, so that the two lifting screws 5 can rotate synchronously.

[0025] The extrusion mechanism includes an extrusion spring 16 arranged in the extrusion groove 14, and the two ends of the extrusion spring 16 are elastically connected to the outer wall of the positioning block 15 and the inner wall of the extrusion groove 14 respectively. The elastic potential energy provided by the extrusion spring 16 can realize the extrusion of the positioning block 15, and can push it into the installation channel 9, thereby realizing a stable connection of the collecting tank 3 relative to the lifting block 7, and convenient disassembly operation.

[0026] A limiting block 8 is installed on the lifting block 7, and a limiting groove 6 corresponding to the limiting block 8 is provided on the inner wall of one side of the opening 4. As shown in the figure, since the limiting block 8 is provided and is in the limiting groove 6, the lifting block 7 is limited and will not rotate with the lifting screw 5. When the lifting screw 5 rotates, the lifting block 7 will only move up and down.

[0027] The support frame 2 is U-shaped, and the vertical cross-sections of the extrusion groove 14 , the positioning block 15 and the installation channel 9 are all rectangular. The rectangular design effectively prevents the positioning block 15 from rotating relative to the extrusion groove 14 and the installation channel 9 .

[0028] When the utility model is used, the material processed by the shearing machine is placed on the conveying device 1, transferred from a high place to a low place and finally transferred to the ground or to a collecting device arranged on the ground, thereby completing the automatic unloading operation. In this process, since the belt assembly on the conveying device 1 moves relative to the scraper bar 10, the debris adhered to its surface can be scraped off by the scraper bar 10 and fall into the collecting trough 3 for collection, which effectively ensures the cleanliness of the conveying device 1.

[0029] In this solution, when the collecting trough 3 collects a certain amount of debris and needs to be processed centrally, the driving motor is started to drive the transmission shaft 11 to rotate. The rotation of the transmission shaft 11 can drive the driving gear 12 to rotate. The driving gear 12 can cooperate with the transmission gear 13 to drive the lifting screw 5 to rotate. When the lifting screw 5 rotates, the lifting block 7 threadedly mounted thereon can cooperate with the positioning block 15 to drive the collecting trough 3 to descend. After it is lowered to a certain height, the positioning block 15 in the installation channel 9 is pressed. The positioning block 15 will compress the extrusion spring 16 into the extrusion groove 14 and disengage from the installation channel 9, thereby releasing the installation of the collecting trough 3. After it is completely disassembled, it can be turned upside down to ensure that the debris collected inside is completely dumped.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
