[0021] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an urban domestic solid waste bag breaking auxiliary device according to an embodiment of the utility model comprises a bag breaking machine 100, the bag breaking machine 100 comprises a box body 110 and a frame body 120, a pair of parallel main shafts 111 are arranged in the box body 110, blades 112 are arranged on the main shafts, each of the main shafts 111 is connected to a driving device, the blades 112 on the two main shafts 111 are staggered and meshed, and the main shafts 111 are driven to rotate by the driving device, when the bagged domestic waste falls into the box body during operation, the garbage bag will be broken by the rotating blades 112 to realize the bag breaking function, and also comprises a pressing bracket 200, a pressing arm 300, a telescopic driving device 400, a proximity switch sensor 500 and an electrical control system;

[0023] The pressing bracket 200 is fixed on the frame body 120; one end of the telescopic driving device 400 is hingedly connected to the box body 110, and the other end of the telescopic driving device 400 is connected to the pressing arm 300 through a pin 600; the telescopic driving device 400 is a cylinder, which provides power for pressing the material for the pressing arm 300. The press arm 300 includes a press arm head 310 and a connecting portion 320. The press arm head 310 is an arc-shaped plate. One side of the press arm head 310 is fixed to the upper end of the connecting portion 320, and the other side of the press arm head 310 faces the box body 110. The lower end of the connecting portion 320 is mounted on the press bracket 200 through a rotating shaft 700. The press arm 300 is driven to rotate around the rotating shaft 700 through the telescopic drive device 400. When the bagged garbage is light or difficult to break, and cannot continue to run, the press arm head 310 can pressurize the garbage bag through the rotation of the press arm 300, so that the blade 112 can pierce the garbage bag, and the bag is broken by the rotation of the blade 112. The utility model pressurizes the bagged garbage by the press arm, so that large, hollow, loose, and light-weight bagged domestic garbage is easier to break, thereby improving the bag breaking efficiency.

[0024] The proximity switch sensor 500 is fixed on the press support 200, the electrical control system is electrically connected to the proximity switch sensor 500 and the telescopic drive device 400, and the bottom of the press arm 300 contacts the proximity switch sensor 500 to feed back an electrical control signal to the electrical control system, thereby limiting the position of the press arm 300. The press arm 300 is limited by the proximity switch sensor 500. When in use, the bottom of the press arm 300 contacts the proximity switch sensor 500, triggering an electrical control signal to the electrical control system, and the electrical control system controls the telescopic drive device 400 to stop working, so that the press arm stops rotating. By limiting the press arm, the press arm is prevented from contacting the blade, thereby ensuring the safety of the bag breaking process.

[0025] Furthermore, the head 310 of the press arm is a quarter-circular arc plate, and the head 310 of the press arm is concentric with the axis of the rotating shaft 700. It is ensured that the head 310 of the press arm rotates regularly during the rotation of the press arm and runs in a circular track. The quarter-circular arc design ensures that the press arm 300 will not hinder the bagged garbage from entering the box, thereby ensuring the normal operation of the equipment.

[0026] The arc radius of the press arm head 310 is equal to the distance from the axis of the rotating shaft 700 to the middle of the two spindles 111. This design ensures that when the press arm head 310 rotates to press the material, one end of the press arm is located in the middle of the spindle 111. During operation, the bagged garbage gradually moves to the middle of the two spindles 111, and the bag is broken by the blade 112. The end of the press arm head 310 is designed to be in the middle of the spindle 111, so that the bagged garbage is pressurized. The design is reasonable, which is convenient for pressurization and can also avoid the problem of missing the press arm head during pressurization.

[0027] The press support 200 includes a support arm 210 and a connecting rod 220. There are two support arms 210, which are arranged on one side of the box 110. The support arms 210 are arranged opposite to each other along the length direction of the box 110, and the connecting rod 220 connects the two support arms 210. The support arms 210 are connected by the connecting rod 220 to ensure the stability of the support arms 210 and high mechanical strength. The support arms are tilted upward and sideways to reserve space for the rotation of the press arm 300, so as to facilitate the rotation and pressurization of the press arm 300.

[0028] The end of the support arm 210 away from the support is equipped with the rotating shaft 700 through a bearing, and a mounting seat is correspondingly fixed at the bottom of the connecting portion 320. The mounting seat is provided with an axial hole, and the rotating shaft 700 is connected to the mounting seat through the axial hole. It is ensured that the press arm 300 can rotate around the rotating shaft 700 as the center, and the rotating flow field is ensured by the bearing installation method, while reducing wear and extending the service life of the device.

[0029] The upper part of the surface of the connection part 320 facing the box body 110 is provided with an articulated seat 321, and the telescopic end of the telescopic driving device 400 is installed on the articulated seat 321 through the pin shaft 600 and the pin shaft gasket. It is ensured that when in use, the telescopic driving device 400 applies force to the upper end of the connection part 320 to ensure that the pressing arm 300 can rotate inward around the rotating shaft 400, thereby achieving pressing and ensuring the normal operation of the device.

[0030] There are two proximity switch sensors 500, which are fixed to the connecting rod 220 through a sensor mounting seat 800. The sensor mounting seat 800 is a seat plate arranged perpendicular to the connecting rod 220, which facilitates the installation of the proximity switch sensor 500 and facilitates the bottom of the connecting part 320 to contact the contact switch sensor 500 for position limiting when rotating. The position of the press arm is limited by two proximity switch sensors 500, which limit the two extreme positions of the end point of the press arm when opening and the end point of the press work, ensuring that the press arm rotates within the two extreme positions, and the equipment has high operating safety.

[0031] The two proximity switch sensors 500 are respectively a first proximity switch sensor 510 and a second proximity switch sensor 520. The first proximity switch sensor 510 is close to the box 110. The first proximity switch sensor 510 is vertically arranged at an angle of 90° to the horizontal plane. The second proximity switch sensor 520 is tilted toward the side away from the box, and the angle between the second proximity switch sensor 520 and the horizontal plane is 150°-160°. The tops of the first proximity switch sensor 510 and the second proximity switch sensor 520 are in the same circle, and the distance from the center of the rotating shaft to the bottom of the connecting part is equal to the radius of the circle. It is ensured that when rotating, the bottom of the connecting part 320 can contact the tops of the two proximity switch sensors 500, thereby triggering an electrical control signal. When the material pressing operation is performed, the electrical control system starts the telescopic drive device 400 to contract, driving the connection part 320 to rotate around the rotating shaft 700, so that the head 310 of the material pressing arm rotates toward the inside of the box 110, and the bagged garbage in the box 110 is pressurized. When the bottom of the material pressing arm 300 (the bottom of the connection part) contacts the first proximity switch sensor 510, an electrical control signal is sent to the electrical control system, and the electrical control system controls the telescopic drive device to stop working, and the material pressing stops. At this time, the material pressing end of the material pressing arm head is above the blade and does not contact the blade. , to ensure the safety of the material pressing work; after the material pressing is completed, the material pressing arm is opened, and the telescopic drive device 400 is extended at the same time, so that the head 310 of the material pressing arm rotates outward, and when the bottom of the material pressing arm 300 (the bottom of the connecting part) contacts the second proximity switch sensor 520, an electrical control signal is sent to the electrical control system, and the electrical control system controls the telescopic drive device to stop working, and the material pressing arm stops at this position. Since the angle between the second proximity switch sensor and the horizontal plane is 150°-160°, it is ensured that the head 310 of the material pressing arm stopped at this position is opened and will not hinder the feeding of garbage. The safety of the device operation is ensured by limiting the limit position.

[0032] The connecting portion 320 is a rectangular frame, which can further reduce the mass of the connecting portion 320, reduce the resistance during rotation, and facilitate rotation.

It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
