Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0024] The grinding bin 1 is provided with a screening component 3 inside, a feed port 106 and a connecting block 107 are provided on the top of the grinding bin 1, and a crushing component 2 is provided on the connecting block 107; the screening component 3 is provided so that the raw materials can be effectively screened during use, and the screened raw materials will fall into the grinding disc 105 for grinding. The crushing component 2 is provided so that the large particles can be effectively crushed during use. This arrangement eliminates the need to screen the materials in advance during the grinding process, and the aggregate can be directly put in from the feed port 106.

[0025] A first discharge port 109 and a second discharge port 111 are provided on one side of the grinding bin 1, a guide hopper 108 is provided at the bottom of the crushing assembly 2, a rolling roller 112 is provided inside the grinding bin 1, a drop hopper 113 is provided inside the grinding bin 1, a grinding disc 105 is connected to the bottom of the drop hopper 113, and the bottom of the grinding disc 105 is connected to the second discharge port 111. The rolling roller 112 enables the material crushed by the crushing assembly 2 to be crushed for a second time during use, ensuring that the particle size of the material entering the grinding disc 105 can meet the grinding requirements.

[0026] As a preferred technical solution in this embodiment, when the raw materials need to be ground, the staff can pour the raw materials into the grinding bin 1 from the feed port 106. At this time, the materials will fall into the screening component 3 under the action of gravity to be screened. After screening, the materials that meet the grinding requirements will fall onto the drop hopper 113 under the action of gravity and then enter the grinding disc 105 for grinding. The large-particle materials after screening will enter the crushing component 2 through the first discharge port 109 for crushing. The crushed materials will fall into the guide hopper 108 under the action of gravity, and then slide from the bottom of the guide hopper 108 to the rolling roller 112 for the final crushing effect. Finally, the crushed materials will enter the grinding disc 105 through the drop hopper 113 to achieve the grinding effect. The ground materials will fall into the receiving barrel 103 under the action of gravity for collection.

[0027] Embodiment 2:

[0028] See also Figure 3-4 In order to achieve a good screening effect, the screening assembly 3 in this embodiment is provided with a screen plate 31, and a plurality of connecting springs 32 are provided on the screen plate 31, and the connecting springs 32 are fixedly connected to the inner wall of the grinding bin 1, and a vibration motor 33 is provided at the bottom of the screen plate 31. In actual use, when the material falls on the screen plate 31, the staff can start the vibration motor 33 to drive the screen plate 31 to vibrate, thereby ensuring that the raw materials can be screened quickly, and effectively speeding up its screening speed.

[0029] In order to achieve the effect of crushing large particles of materials, the crushing assembly 2 in this embodiment is provided with a mounting platform 21 and a crushing bin 24, and the mounting platform 21 is fixedly connected to the connecting block 107. A connecting port 25 is provided on the crushing bin 24, and the connecting port 25 is connected to the first discharge port 109, and a screening port 26 is provided at the bottom of the crushing bin 24. A hydraulic push rod 22 is provided on the mounting platform 21, and a pressure block 23 is fixedly connected to the push rod end of the hydraulic push rod 22.

[0030] As a preferred technical solution in this embodiment, in actual use, large particles of material will slide into the crushing bin 24 under the action of gravity after being screened by the screen plate 31. At this time, the large particles of material with a volume smaller than the width of the screening port 26 will slide through the screening port 26 at the bottom of the crushing bin 24 to the rolling roller 112 for crushing, while the materials with a volume larger than the width of the screening port 26 will remain in the crushing bin 24. At this time, the staff can control the hydraulic push rod 22 to drive the pressure block 23 to produce an up and down displacement effect. In the process of the up and down displacement of the pressure block 23, it can effectively drive the large particles of material in the crushing bin 24 to be crushed. After crushing, the material will slide into the rolling roller 112 through the screening port 26 under the action of gravity for further crushing. The crushed material enters the grinding disc 105 through the drop hopper 113 for grinding, thereby achieving the grinding effect.

[0031] The working principle of the above embodiment is:

[0032] 1. When it is necessary to grind the raw materials, the staff can pour the raw materials into the grinding bin 1 from the feed port 106. At this time, the materials will fall into the screening component 3 under the action of gravity to be screened. After screening, the materials that meet the grinding requirements will fall onto the drop hopper 113 under the action of gravity and then enter the grinding disc 105 for grinding. The large particles after screening will enter the crushing component 2 through the first discharge port 109 for crushing. The crushed materials will fall into the guide hopper 108 under the action of gravity, and then slide from the bottom of the guide hopper 108 to the rolling roller 112 for the final crushing effect. Finally, the crushed materials will enter the grinding disc 105 through the drop hopper 113 to achieve the grinding effect. The ground materials will fall into the receiving barrel 103 under the action of gravity for collection.

[0033] 2. In actual use, after being screened by the sieve plate 31, the large particles will slide into the crushing bin 24 under the action of gravity. At this time, the large particles with a volume smaller than the width of the screening opening 26 will slide through the screening opening 26 at the bottom of the crushing bin 24 to the rolling roller 112 for crushing, while the materials with a volume larger than the width of the screening opening 26 will remain in the crushing bin 24. At this time, the staff can control the hydraulic push rod 22 to drive the pressing block 23 to produce an effect of up and down displacement. In the process of the up and down displacement of the pressing block 23, the large particles in the crushing bin 24 can be effectively crushed. After crushing, the materials will slide into the rolling roller 112 through the screening opening 26 under the action of gravity for further crushing. The crushed materials enter the grinding disc 105 through the drop hopper 113 for grinding, thereby achieving the grinding effect.
