[0035] As Figures 1-6 shown, a snow-melting agent crushing mechanism with adjustable specifications proposed by the present utility model includes a crushing bin 1, and a receiving box 5 for receiving snow-melting agent materials is placed at the lower end of the crushing bin 1;

[0036] A feeding port 2 for feeding materials is opened at the upper end of the crushing bin 1, and connecting frames 3 are fixedly connected to both the one side and the other side of the crushing bin 1;

[0037] A crushing member 8 for crushing the snow-melting agent is provided on the crushing bin 1;

[0038] A screening member 7 for screening the crushed snow-melting agent is provided inside the crushing bin 1.

[0039] In the present utility model, the snow-melting agent fed into the feeding port 2 is crushed by the crushing member 8 on the crushing bin 1. At the same time, the crushed snow-melting agent is vibrated and screened out by the screening member 7.

[0040] In an optional embodiment, the screening member 7 includes a screening frame 71 slidably connected to the inner wall of the crushing bin 1. Screening holes 72 are formed in the screening frame 71. The number of the screening holes 72 is several, and the several screening holes 72 are arranged in an array on the inner bottom wall of the screening frame 71. A material guiding frame 74 is fixedly connected to the lower end of the screening frame 71, and one end of the material guiding frame 74 penetrates through the crushing bin 1. The material guiding frame 74 is communicated with the screening holes 72. A vibrating plate 73 for driving the screening frame 71 is slidably connected to the inner wall of the crushing bin 1. A convex block 79 extending into the interior of the crushing bin 1 is fixedly connected to one side of the vibrating plate 73 away from the material guiding frame 74. A groove 78 is formed in the inner wall of the crushing bin 1 outside the convex block 79. A support rod 75 penetrating through the convex block 79 is fixedly connected to the inner side wall of the groove 78. A support spring 77 is fixedly connected between the convex block 79 and the groove 78.

[0041] It should be noted that a cam 76 for driving the vibrating plate 73 is provided on the crushing member 8, and a transmission member 710 for transmission is provided on the crushing member 8. During the rotation of the cam 76 on the crushing member 8 following the crushing member 8, the vibrating plate 73 can be repeatedly squeezed, so as to repeatedly lift the vibrating plate 73, and the vibrating plate 73 drives the screening frame 71 to vibrate and screen.

[0042] Among them, the number of the vibrating plates 73 is two, and the two vibrating plates 73 are symmetrically distributed on the inner wall of the crushing bin 1 and are located below the screening frame 71. The screening frame 71 is stably driven to vibrate by the two symmetrically distributed vibrating plates 73 below the screening frame 71. The convex block 79 is slidably connected to the inside of the groove 78 and is located outside the support rod 75. The convex block 79 is supported by the support rod 75 penetrating through the convex block 79, so that the convex block 79 can limit the stable vibration of the vibrating plate 73.

[0043] In addition, the number of the cams 76 is four, and the four cams 76 are symmetrically distributed in two groups on the inner wall of the crushing bin 1 for driving the two vibrating plates 73 to vibrate synchronously. The two groups of symmetrically distributed cams 76 are used to stably drive the vibrating plates 73 on both sides to vibrate synchronously. A rectangular hole for the material guiding frame 74 to slide is formed in the inner bottom wall of the crushing bin 1, so that the material guiding frame 74 penetrating through the crushing bin 1 can lead the snow melting agent material screened by the screening holes 72 into the receiving box 5.

[0044] In this embodiment, through the cooperation of the vibrating plate 73 on the screening member 7 and the screening frame 71, the crushed snow melting agent can be vibrated and screened, so that the specifications of the screened snow melting agent are unified, thereby improving the snow melting speed and effect in the subsequent use process of the snow melting agent, achieving the effect of facilitating screening.

[0045] In an optional embodiment, the crushing member 8 includes two motors 81 fixedly connected to the inner wall on the left side. The two motors 81 are driven to run synchronously by conventional control devices such as a controller or a control panel, and both the controller and the control panel are existing well-known mechanical devices. Therefore, their working principles and specific structures will not be elaborated in the text and the drawings. The output shaft of the motor 81 is fixedly connected to a rotating shaft 82 that penetrates through the crushing chamber 1 at one end and extends to the inside of the connecting frame 3 on the right side. A number of crushing rods 83 are fixedly connected to the outer sides of the two rotating shafts 82 and are located inside the crushing chamber 1. The inner wall of the connecting frame 3 is rotatably connected to a connecting shaft 84 that penetrates through and extends to the inside of the crushing chamber 1 at one end. The cam 76 is located at the end of the connecting shaft 84, and the transmission member 710 is located on the connecting shaft 84 and the rotating shaft 82. The number of connecting shafts 84 is four, and the four connecting shafts 84 are symmetrically distributed in two groups on the inner wall of the connecting frame 3.

[0046] It should be noted that the transmission member 710 includes four pulleys respectively arranged on the rotating shaft 82 and the connecting shaft 84, and a movable belt is sleeved on the pulleys, so that the rotating rotating shaft 82 can drive the connecting shaft 84 to rotate synchronously through the pulleys and the movable belt.

[0047] In this embodiment, after the started motor 81 drives the crushing rods 83 on the two rotating shafts 82 to rotate in opposite directions, the snow melting agent input through the feeding port 2 can be crushed. After the rotating rotating shaft 82 drives the connecting shaft 84 to rotate through the transmission member 710, the cam 76 on the connecting shaft 84 can be driven to rotate synchronously to drive the vibrating plate 73 to vibrate.

[0048] In an optional embodiment, a placement hole 4 for placing the screening frame 71 is provided on the front surface of the crushing chamber 1. The limiting member 6 includes a support block 64 provided on the crushing chamber 1. A limiting rod 61 is provided on the support block 64, and a stop block 62 is provided on the limiting rod 61. A return spring 63 is provided between the stop block 62 and the support block 64.

[0049] It should be noted that a through hole for the limiting rod 61 to slide is provided on the support block 64. The limiting rod 61 is U-shaped, and the lower end of the limiting rod 61 is L-shaped. The lower end of the limiting rod 61 abuts against the screening frame 71, and the end of the limiting rod 61 that abuts against the screening frame 71 is arc-shaped, so that when the limiting rod 61 abuts against the screening frame 71, it will not affect the vibration of the screening frame 71, and at the same time, it can provide the stability of the screening frame 71 during vibration.

[0050] Among them, a connecting groove is provided on the front surface of the crushing chamber 1, and one end of the connecting groove is communicated with the placement hole 4. The connecting groove is located above the L end of the limiting rod 61, so that when the limiting rod 61 is pulled upward, the L end of the limiting rod 61 has room to move upward.

[0051] In this embodiment, the limiting rod 61 on the limiting member 6 can limit and block the screening frame 71 during the vibration screening process to provide stability for the screening frame 71 during vibration. By pulling the limiting rod 61 upward, the screening frame 71 can be withdrawn for replacement, thereby adjusting the screening specifications.

[0052] The working principle of the above embodiment is as follows:

[0053] After the snow melting agent to be broken is put into the feeding port 2, the motor 81 can be started to drive the crushing rods 83 on the two rotating shafts 82 to rotate in opposite directions to crush the snow melting agent put into the feeding port 2. After the rotating shaft 82 rotates and drives the connecting shaft 84 to rotate through the belt pulley on the transmission member 710 and the movable belt, the cam 76 on the connecting shaft 84 can be driven to rotate synchronously to drive the vibrating plate 73 to vibrate. After the vibrating plate 73 vibrates and the screening frame 71 is driven to vibrate, the crushed snow melting agent can be vibrated and screened to make the specifications of the screened snow melting agent uniform, so as to improve the snow melting speed and effect in the subsequent use process of the snow melting agent. After the screened snow melting agent is exported through the guide frame 74, it can fall into the receiving box 5 for collection. The limiting rod 61 on the support block 64 can limit and block the screening frame 71 during the vibration screening process to provide stability for the screening frame 71 during vibration. By pulling the limiting rod 61 upward so that it does not contact the screening frame 71, the screening frame 71 can be withdrawn for replacement, and the screening frame 71 with different specifications of screening holes 72 can be selected and put back into the crushing bin 1 to adjust the screening specifications.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
