[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 One embodiment provided by this utility model:
[0023] A grinding mill for producing natural asphalt raw materials includes a housing 1. A motor 2 is fixedly connected to the surface of the housing 1, and a crushing roller 21 is fixedly connected to the output end of the motor 2. A filter structure 3 is provided at the bottom of the housing 1. The filter structure 3 includes two sets of connecting grooves 31, which are respectively opened on both sides of the housing 1. A collection box 32 is fixedly connected to the outer side of each set of connecting grooves 31. A collection cassette 33 is inserted into the inside of the collection box 32. A storage box 34 is inserted into the inside of the housing 1. A filter plate 35 is fixedly connected to the inner wall of the housing 1. A discharge structure 4 is provided at the top of the housing 1. 4 includes a feed inlet 41, with a storage pipe 42 fixedly connected to the bottom of the feed inlet 41. The storage pipe 42 has four sets of sliding grooves 43 inside, each with a slider 44 slidably connected inside. A connecting rod 45 is fixedly connected to the bottom of the slider 44, and a spring 46 is fixedly connected to the bottom of the slider 44. A base plate 47 is fixedly connected to the bottom of the connecting rod 45. Guide grooves 48 are provided on both sides of the base plate 47, and a guide block 49 is fixedly connected to the top of the base plate 47. A second sliding groove 410 is provided on the surface of the guide block 49. A reduction motor 411 is fixedly connected to the surface of the storage pipe 42. A rotating rod 412 is fixedly connected to the output end of the motor 411. Two sets of cams 413 are fixedly connected to the surface of the rotating rod 412. A feeding structure 4 is set up so that raw materials are added from the feed inlet 41 and stored in the storage tube 42. The rotating rod 412 is driven to rotate by the reduction motor 411, so that the cams 413 rotate with the rotating rod 412. Under the action of the spring 46, the slider 44 is pushed upward. The bottom plate 47 is pressed against the bottom of the storage tube 42 and contacts the surface of the cams 413 through the connecting rod 45. When the cams 413 rotate, they reciprocate to push the bottom plate 47 downward and under the action of the spring 46. The bottom plate 47 is opened and closed repeatedly by moving up and down, allowing for intermittent feeding during material feeding. This prevents raw materials from accumulating in the box 1 and affecting the grinding effect. A filter structure 3 is provided, and the ground raw materials fall onto the surface of the filter plate 35. The filter plate 35 screens the raw materials, and the fully ground raw materials enter the storage box 34. The raw materials that are not fully ground and cannot pass through the filter plate 35 enter the collection boxes 33 on both sides through the connecting groove 31 along the surface of the filter plate 35. After production is completed, the raw materials can be screened directly without adding an extra screening step, reducing production steps and making it more convenient to use.
[0024] Furthermore, both motor 2 and geared motor 411 are electrically connected to an external power source, which supplies power to motor 2 and geared motor 411 and controls them uniformly.
[0025] Furthermore, the filter plate 35 is in the shape of an inverted V and is located below the crushing roller 21. Both ends of the filter plate 35 are fixedly connected to two sets of connecting grooves 31. The storage box 34 is located at the bottom of the filter plate 35. The raw materials are screened through the filter plate 35. The fully ground raw materials enter the storage box 34, while the raw materials that are not fully ground and cannot pass through the filter plate 35 enter the collection boxes 33 on both sides through the connecting grooves 31 along the surface of the filter plate 35.
[0026] Furthermore, a square groove is provided on the top of the box 1, and the storage pipe 42 is fixedly connected in the square groove. Raw materials are added from the inlet 41 and stored in the storage pipe 42.
[0027] Furthermore, the two ends of the spring 46 are fixedly connected to the bottom of the slider 44 and the bottom of the inner wall of the groove 43, respectively. The spring 46 is sleeved on the outside of the connecting rod 45. There are four sets of connecting rods 45, and the four sets of connecting rods 45 are fixedly connected to the top four corners of the base plate 47. The spring 46 is made of stainless steel, which has good corrosion resistance and high mechanical properties and a long service life. When the raw material is stored in the storage tube 42, the force of the spring 46 will offset the weight of the raw material, so that the base plate 47 still abuts against the bottom of the storage tube 42.
[0028] Furthermore, the guide block 49 is triangular and is positioned between two sets of guide grooves 48. The rotating rod 412 is slidably connected in the second slide groove 410. When the cam 413 is rotated by the reduction motor 411 to push the bottom plate 47 downward, the guide block 49 guides the raw material to facilitate material unloading. The guide grooves 48 cooperate with the guide block 49 to prevent the raw material from staying on the top of the bottom plate 47 during unloading. When the bottom plate 47 moves, the guide block 49 moves with the bottom plate 47 on the rotating rod 412 through the second slide groove 410.
[0029] Furthermore, rotating grooves are provided on both sides of the storage pipe 42. The rotating grooves are fan-shaped, and the cam 413 is rotatably connected in the rotating groove. The surface of the cam 413 abuts against the base plate 47. When the cam 413 is driven to rotate by the reduction motor 411, the protrusion of the cam 413 rotates out from the rotating groove and pushes the base plate 47 to move. The opening of the rotating groove is set at the bottom of the storage pipe 42 to prevent raw materials from entering the rotating groove.
[0030] Working principle: During use, raw materials are added through the feed inlet 41 and stored in the storage tube 42. The geared motor 411 drives the rotating rod 412 to rotate, causing the cam 413 to rotate with the rotating rod 412. Under the action of the spring 46, the cam 413 pushes the slider 44 upward. Through the connecting rod 45, the bottom plate 47 abuts against the bottom of the storage tube 42 and contacts the surface of the cam 413. When the cam 413 rotates, it reciprocates to push the bottom plate 47 downward and upward under the action of the spring 46, realizing the reciprocating opening and closing of the bottom plate 47. The material can be fed intermittently during feeding. The crushing roller 21 is driven by motor 2 to grind the raw material. The ground raw material falls on the surface of the filter plate 35 and is screened by the filter plate 35. The fully ground raw material enters the storage box 34, while the raw material that is not fully ground and cannot pass through the filter plate 35 enters the collection boxes 33 on both sides through the connecting groove 31. The collection box 33 and the storage box 34 can be taken out by pulling out for subsequent production, which is convenient to use.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
