[0031] Referring to Figures 1-5 , a polymer pipe waste crushing device includes a frame 1, a crusher box 2, and a feeding box 3 arranged in sequence from bottom to top. One end of the bottom of the feeding box 3 is hinged to one end of the top of the crusher box 2, and the other end is connected to one end of the top of the crusher box 2 through a movable locking assembly 4. A telescopic cylinder 5 for driving the crusher box 2 to flip is provided between the feeding box 3 and the frame 1, and the inner cavity of the crusher box 2 is communicated with the inner cavity of the feeding box 3. A feeding port is provided on the front side of the feeding box 3, and a curtain assembly 7 for blocking the feeding port is provided in the feeding box 3. The curtain assembly 7 includes a mounting circular shaft 71 mounted on the feeding box 3 and a plurality of metal baffles 72 distributed along the axial direction of the mounting circular shaft 71. The tops of the plurality of metal baffles 72 are rotatably connected to the mounting circular shaft 71.

[0032] Furthermore, the metal baffle 72 is provided with a counterweight 721 for increasing the weight of the metal baffle 72. The counterweight 721 is located at the lower end of the rear side of the metal baffle 72. By adding the counterweight 721, the weight of the metal baffle 72 is increased, making it difficult for the metal baffle 72 to be knocked open by the splashing waste fragments, thereby ensuring that the metal baffle 72 can better play the role of preventing waste fragments from splashing out from the feeding port. Moreover, since the counterweight 721 is located at the rear side of the metal baffle 72, it avoids interference between the waste and the counterweight 721 when the worker adds waste to the feeding box 3, thus ensuring that the worker can normally add waste to the crushing device. At the same time, the counterweight 721 is located at the lower end of the metal baffle 72, and the downward gravity of the metal baffle 72 is large. After the waste abuts against the front side of the metal baffle 72 and causes the metal baffle 72 to swing around the mounting circular shaft 71 to an inclined state to allow the waste to completely enter the feeding box 3, the metal baffle 72 can quickly flip back to the vertical state and block the feeding port to prevent waste fragments from splashing out.

[0033] Furthermore, a blocking module 8 for restricting the forward swing of the lower end of the metal baffle 72 is installed in the feed box 3. The axial direction of the blocking module 8 is parallel or nearly parallel to the axial direction of the mounting round shaft 71, and the blocking module 8 is located in front of the metal baffle 72. When the metal baffle 72 is in a vertical state or nearly vertical state, the blocking module 8 is in movable abutment with the front side of the metal baffle 72. The blocking module 8 is used to block the metal baffle 72 and restrict the forward swing of the lower end of the metal baffle 72, further enhancing the effect that the metal baffle 72 is not easily knocked open, further strengthening the function of the metal baffle 72 to prevent waste fragments from splashing out from the feed port position, thereby effectively avoiding personal injuries caused by the splashing of waste fragments and improving the safety performance of the crushing equipment. In addition, the blocking module 8 is arranged near the top of the metal baffle 72 to avoid interfering with the material.

[0034] In this embodiment, a crushing motor 6 is provided on the frame 1. A crushing rotating shaft 61 driven by the crushing motor 6 is rotatably installed on the upper part of the crusher box 2. A crushing tool holder 62 located inside the crusher box 2 is installed on the crushing rotating shaft 61. A plurality of rotating tools are installed on the crushing tool holder 62. A fixed tool is installed on the upper part of the crusher box 2. A feed hopper is provided on the side surface of the feed box 3. A semi-circular screen 9 is arranged below the crushing tool holder 62 inside the crusher box 2. An outlet is provided at the bottom of the crusher box 2 below the semi-circular screen 9. A receiving groove 10 for receiving the raw material particles discharged from the outlet is provided inside the frame 1.

[0035] As a preferred embodiment, the blocking module 8 includes a blocking shaft 81 and a rubber sleeve 82 sleeved on the blocking shaft 81. The rubber sleeve 82 is used to contact the front side of the metal baffle 72, thereby reducing the impact force when the metal baffle 72 swings forward and resets.

[0036] As a preferred embodiment, a plurality of intermediate spacers 11 are sleeved on the mounting round shaft 71. Adjacent metal baffles 72 on the left and right are separated by one of the intermediate spacers 11, thereby preventing the metal baffles 72 from colliding and interfering with each other and facilitating the swing and reset of the metal baffles 72.

[0037] As a preferred embodiment, two mounting seats 12 are provided in the feeding chassis 3. The two mounting seats 12 are respectively installed on the left inner side and the right inner side of the feeding chassis 3 and are symmetrically arranged left and right. The mounting seat 12 is provided with a first support groove 121 and a second support groove 122; both the blocking shaft 81 and the mounting circular shaft 71 are located between the two mounting seats 12. Both the left and right ends of the blocking shaft 81 are provided with blocking mounting parts 811 that fit into the first support groove 121; both the left and right ends of the mounting circular shaft 71 are provided with circular shaft mounting parts 711 that fit into the second support groove 122, so that the two mounting seats 12 support and install the blocking shaft 81 and the mounting circular shaft 71.

[0038] As a preferred embodiment, both of the two mounting seats 12 include a first support portion 123, a second support portion 124, and a blocking and mounting portion 125 that are connected in sequence from front to back. The bottom surfaces of the first support portion 123, the second support portion 124, and the blocking and mounting portion 125 are flush. The heights of the first support portion 123, the second support portion 124, and the blocking and mounting portion 125 increase in sequence from front to back. The first support groove 121 is provided on the top surface of the first support portion 123. The first support groove 121 is recessed downward on the top surface of the first support portion 123 and penetrates the first support portion 123 from left to right, so as to facilitate the blocking mounting part 811 to be inserted into the first support groove 121 in a matching manner. The second support groove 122 is provided on the top surface of the second support portion 124. The second support groove 122 is recessed downward on the top surface of the second support portion 124 and penetrates the second support portion 124 from left to right, so as to facilitate the circular shaft mounting part 711 to be inserted into the second support groove 122 in a matching manner.

[0039] As a preferred embodiment, the rear groove surface of the first support groove 121 is flush with the front side surface of the second support portion 124, and the rear groove surface of the second support groove 122 is flush with the front side surface of the blocking and mounting portion 125, so that the blocking shaft 81 and the mounting circular shaft 71 can be blocked and limited by using the front side surfaces of the second support portion 124 and the blocking and mounting portion 125 respectively, and the end of the blocking shaft 81 can quickly enter the first support groove 121 and the end of the mounting circular shaft 71 can quickly enter the second support groove 122.

[0040] As a preferred embodiment, the mounting seat 12 is installed in the feeding chassis 3 by using first screws to complete the fixation of the mounting seat 12. In addition, the blocking mounting part 811 and the circular shaft mounting part 711 are respectively connected to the feeding chassis 3 by using second screws and third screws to further improve the installation quality of the mounting circular shaft 71 and the blocking shaft 81.

[0041] As a preferred embodiment, the front slot surfaces and rear side surfaces of the first bracket 121 and the second bracket 122 are both anti-rotation planes. The front side and the rear side of the blocking installation portion 811 and the circular shaft installation portion 711 are both provided with mating planes that cooperate with the anti-rotation planes. Under the cooperation between the anti-rotation plane and the mating plane, the mounting circular shaft 71 and the blocking shaft 81 are both non-rotatably arranged, avoiding the rotation of the mounting circular shaft 71 and the blocking shaft 81 from affecting their installation stability.

[0042] As a preferred embodiment, the top end of the metal baffle 72 is a rotating sleeve 722 rotatably sleeved on the mounting circular shaft 71. The metal baffle 72 rotates and swings based on the rotational cooperation between the rotating sleeve 722 and the mounting circular shaft 71. Additionally, the rotating sleeve 722 and the counterweight 721 can be integrally formed and connected to the metal baffle 72, or can be connected to the metal baffle 72 by welding. Preferably, the rotating sleeve 722 and the counterweight 721 are integrally formed and connected to the metal baffle 72, thereby ensuring the structural stability between them.

[0043] As a preferred embodiment, two side-end spacers 14 are also sleeved on the mounting circular shaft 71. One side-end spacer 14 is located between the left mounting seat 12 and the leftmost metal baffle 72, and the other side-end spacer 14 is located between the right mounting seat 12 and the rightmost metal baffle 72, thereby preventing the metal baffle 72 from directly rubbing against the mounting seat 12 when swinging. Additionally, the intermediate spacer 11 and the side-end spacers 14 are both made of circular rings of the same specification size. The thicknesses of the intermediate spacer 11 and the side-end spacers 14 are both not greater than 3 mm. Preferably, the thicknesses of the intermediate spacer 11 and the side-end spacers 14 are 2 mm, so that while separating the various components, the distance between them is not too large, reducing the probability of waste fragments splashing out.

[0044] The above are only the preferred embodiments of the present utility model. As long as the technical solutions that achieve the purpose of the present utility model by basically the same means fall within the protection scope of the present utility model.
