[0030] The present utility model will be described in detail below with reference to the accompanying drawings:

[0031] In an embodiment of the present utility model, an automatic soil crushing and mixing system is disclosed. As Figure 1-8 shown, it includes a crushing bin 1, a feed roller cutter 2, a crushing and mixing hammer 3, and a driving motor 4; the feed roller cutter 2 and the crushing and mixing hammer 3 are installed inside the crushing bin 1; the upper part of the crushing bin 1 is provided with a feed inlet 11, and the lower part is provided with a discharge outlet 12. The feed roller cutter 2 is arranged at the feed inlet 11, and the crushing and mixing hammer 3 is arranged above the discharge outlet 12, and the crushing and mixing hammer 3 is located below the feed roller cutter 2; the driving motor 4 is installed outside the crushing bin 1, and the feed roller cutter 2 and the crushing and mixing hammer 3 are respectively driven by the driving motor 4.

[0032] Specifically, in this embodiment, the above-mentioned feed roller cutter 2 is composed of a first transmission shaft 21 and a roller cutter group 22. The roller cutter group 22 includes a first roller cutter group 221 and a second roller cutter group 222. Both the first roller cutter group 221 and the second roller cutter group 222 are provided with several groups and are arranged alternately on the outer circumference of the first transmission shaft 21. Both the first roller cutter group 221 and the second roller cutter group 222 are composed of three roller cutters, and the roller cutters of the first roller cutter group 221 and the second roller cutter group 222 are arranged in periodic symmetry to form a dense and uniform feed structure, as Figure 3-4 shown.

[0033] It should be noted that the above-mentioned feed inlet 11 is opened on one side of the crushing bin 1 and is matched with the rotation direction of the roller cutter group 22. During use, the material is conveyed into the crushing bin 1 through the feed inlet 11 in cooperation with a feed conveyor. In addition, a shaft hole 13 is opened on the outer wall of the crushing bin 1 corresponding to the first transmission shaft 21. The shaft hole 13 is set as a waist-shaped chute to facilitate larger particles to enter the feed inlet 11 and avoid material jamming at the feed inlet 11.

[0034] In this embodiment, the above-mentioned crushing and mixing hammers 3 are arranged in three groups, with the same structural dimensions, and are dispersedly arranged in a triangular shape at the bottom of the feed roller 2. Each group of crushing and mixing hammers 3 is composed of a second transmission shaft 31 and a hammer head group 32. The hammer head group 32 includes a first hammer head group 321 and a second hammer head group 322. The first hammer head group 321 and the second hammer head group 322 are both arranged in several groups and are staggered on the outer periphery of the second transmission shaft 31. The first hammer head group 321 and the second hammer head group 322 are both composed of four hammer heads. The hammer heads of the first hammer head group 321 and the second hammer head group 322 are arranged in a periodic symmetrical manner to form a dense and uniform crushing and mixing area, such as Figure 5-6 shown.

[0035] In addition, in order to meet the adjustable speed of the feed roller 2 and the crushing mixing hammer 3, in this embodiment, the number of the above-mentioned drive motors 4 is consistent with the total number of the feed roller 2 plus the crushing mixing hammer 3, and the drive motors 4 are respectively connected to the feed roller 2 and the crushing mixing hammer 3.

[0036] In this embodiment, the above-mentioned crushing and mixing system adopts an adjustable speed feed roller 2 to automatically and evenly feed. First, the rotation speed of the feed roller 2 is adjusted by the drive motor 4, and the frequency of the roller group 22 of the feed roller 2 can be adjusted. Since the feed amount remains unchanged, the frequency of the feed roller 2 is increased, so that the particles of the feed material become finer, thereby ensuring that the first process achieves the crushing effect; secondly, in order to prevent the feed port 11 from being blocked due to the presence of larger particles in the feed material during the feeding process, the axial hole 13 of the feed roller 2 is designed as a waist-shaped chute, so that when larger particles enter the feed area and get stuck, the feed roller 2 can automatically let go of the knife to reduce the risk of blocking. Figure 8 shown.

[0037] At the same time, in order to cope with different soil qualities, such as high-quality soil mixed with a small amount of gravel, general soil, gravel soil and sandy soil mixed with fine sand, this embodiment is provided with three sets of crushing and mixing hammers 3 in the second path, and multiple crushing can be performed through the speed combination ratio of the three sets of crushing and mixing hammers 3, such as Figure 7 As shown, the number ① is the 1# breaker hammer, the number ② is the 2# breaker hammer, and the number ③ is the 3# breaker hammer. The 1# breaker hammer, the 2# breaker hammer, and the 3# breaker hammer are divided into three layers and are staggered. The 1# breaker hammer is located at the upper right, the 2# breaker hammer is located in the middle and left, and the 3# breaker hammer is located at the lower right. Compared with the existing equipment, this embodiment is more targeted, and different speed ratios can be selected to deal with different soil types. In addition, different particle sizes can be achieved by selecting different rotation speeds. It has high selectivity and better applicability. Figure 9-10 shown. Figure 10 In the figure, the characters L, M, G, and H represent low speed, medium speed, high speed, and rapid speed respectively.

[0038] The technical solution of the present utility model is disclosed above. The working principle of the automatic soil crushing and mixing system of the present utility model is as follows: As Figure 7 shown, the soil A to be crushed and mixed is conveyed to the crushing bin 1 through the feeding conveyor at the feeding port 11. The feeding roller cutter 2 rotates at high speed to evenly dial the soil. The falling soil enters the B area and is crushed by the high-speed rotating No. 1 crushing hammer. It falls into the C area and is then jointly struck by the high-speed rotating No. 1 crushing hammer and the high-speed rotating No. 2 crushing hammer for secondary crushing and mixing. It falls into the D area. Finally, it is jointly struck by the high-speed rotating No. 2 crushing hammer and the high-speed rotating No. 3 crushing hammer for tertiary crushing and mixing. It falls into the E area and is conveyed out through the discharging conveyor under the discharging port 12.

[0039] In order to better implement this embodiment, the feeding port described above may further include a height-limiting and leveling device to ensure that the conveying volume is basically constant. At the same time, the speeds of the feeding conveyor and the feeding roller cutter are adjustable to ensure that the feeding volume can be adjusted according to requirements, and the feeding is stable and fast; the No. 1 crushing hammer, the No. 2 crushing hammer, and the No. 3 crushing hammer rotate at the same speed, in opposite rotation directions, and the speed is adjustable. The discharging conveyor can meet the requirement of outputting materials at any time.

[0040] The technical solution disclosed by the present utility model has the following advantages compared with the prior art:

[0041] 1. The present utility model uses a speed-adjustable feeding roller cutter to ensure that the inside of the crushing bin can automatically and evenly feed materials, with stable feeding and fast speed;
