It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0033] like Figure 1 , 2As shown in Figures 3 and 4, a horizontal impact sand making machine comprises a casing 1, a rotor 2 and a feed hopper 3. The rotor 2 is located in the casing 1, and the feed hopper 3 is installed on the side wall of the casing 1. The casing 1 comprises a base 4, a left half shell 5 and a right half shell 6. The left half shell 5 and the right half shell 6 are connected by screws 7 and are arranged on the base 4. The left half shell 5 and the right half shell 6 are hinged to the base 4 by a left hinge shaft 8 and a right hinge shaft 9, respectively. A left power-assisted pull spring 10 is connected between the left half shell 5 and the base 4, and a right power-assisted pull spring 11 is connected between the right half shell 6 and the base 4. During maintenance, the left half shell 5 and the right half shell 6 are opened on both sides. After opening, there is a large space for maintenance, and it is time-saving, labor-saving, and convenient to replace wearing parts. The power-assisted pull spring is added, and it is effortless when closing the casing, and maintenance is convenient.

[0034] like Figure 5 , 6 As shown in FIGS. 7 and 8, the rotor 2 includes a rotating shaft 12, a sleeve 13, a fixed plate 14 and a crushing impact cage 15. The sleeve 13 is fixed on the rotating shaft 12, and the fixed plate 14 is fixed on the sleeve 13 and is perpendicular to the sleeve 13. The fixed plate 14 is located at one end of the sleeve 13 and is integrally formed with the sleeve 13. The crushing impact cage 15 is sleeved on the periphery of the rotating shaft 12. One end of the crushing impact cage 15 is fixedly connected to the fixed plate 14. An annulus 16 is formed between the other end of the crushing impact cage 15 and the rotating shaft 12. The rotating shaft 12 is installed on the left bearing seat 17 and the right bearing seat 18 on the casing 1. The crushed stone enters the crushing impact cage 15 from the annulus 16 through the feed hopper 3. The stone is crushed after multiple collisions in the crushing impact cage 15. In the crushing impact cage, the stone is not only crushed by the crushing impact hammer, but also effectively crushed by "stone hitting stone" through the collision between the stones, thereby reducing the wear of the crushing parts. This crushing method improves the crushing efficiency, especially it can crush stones with a diameter of 10mm. Compared with the existing sand making machine, the stone diameter or particle size is doubled, which greatly reduces the requirements for the stone.

[0035] The crushing impact cage 15 includes a circular baffle 19, a plurality of crushing impact hammers 20 and an annular baffle plate 21. The crushing impact hammers 20 are located between the annular baffle plate 21 and the circular baffle plate 19. The plurality of crushing impact hammers are spaced and distributed on the edge of the plate surface of the circular baffle plate 19. The annular baffle plate is located on the periphery of the rotating shaft. The annular space 16 is formed between the rotating shaft 12 and the central hole of the annular baffle plate 21. The central part of the circular baffle plate 19 is provided with a sleeve hole 22. The sleeve hole 22 of the circular baffle plate is inserted on the sleeve 13. The fixed plate 14 is fixedly connected to the circular baffle plate 19 by screws 23. The crushing impact hammers 20 are fixedly connected to the annular baffle plate 21 and the circular baffle plate 19 by screws 24, respectively.

[0036] The crushing impact hammer 20 is an L-shaped structure consisting of a radial segment and a tangent segment, one end of the radial segment points to the rotating shaft, the other end of the radial segment is connected to the tangent segment, and the tangent segment is perpendicular to the radial segment. Specifically, the crushing impact hammer 20 includes an L-shaped base 25, a semi-cylindrical hammer head 26 and an L-shaped hammer head 27, the semi-cylindrical hammer head 26 is provided with a notch 28, the semi-cylindrical hammer head 26 is located at one end of the L-shaped base 25 and the inner corner of the end is located in the notch 28, and the L-shaped hammer head 27 is located at the other end of the L-shaped base 25 and the inner corner of the end is wrapped by the L-shaped hammer head 27.

[0037] Fixed impact teeth 29 are provided on the inner wall of the casing 1. The crushed materials formed after multiple impacts in the crushing impact cage 15 are thrown out from the gaps between the crushing impact hammers 20 to the fixed impact teeth 29 outside the crushing impact cage.

[0038] A protective annular plate 30 is fixed to one side of the annular baffle plate 21, and the protective annular plate 30 covers the circumferential surface and the side wall surface of the annular baffle plate 19. The protective annular plate 30 is composed of a plurality of fan-shaped plates. The plate surface of the circular baffle plate 19 is provided with an anti-wear lining plate 31; the shaft sleeve 13 is sleeved with an anti-wear sleeve 32. The wear of the crushing parts is relatively reduced, and the replacement cycle of the crushing parts is extended by 5-7 times, which greatly improves the continuous production cycle.

[0039] Working principle: This machine adopts a two-stage crushing method of coarse crushing and fine crushing. First, the stone enters the crushing impact cage for crushing. In the crushing impact cage, the stone is not only crushed by the crushing impact hammer, but also through the mutual collision between the stones, using "stone hitting stone" for effective crushing, which reduces the wear of the crushing parts and can crush stones with a diameter of 10mm. The broken materials formed after multiple collisions in the crushing impact cage are thrown out from the gap between the crushing impact hammers to the fixed impact teeth outside the crushing impact cage, forming secondary crushing, which is the so-called fine crushing. This crushing method avoids the direct use of "iron hitting stone" method and cleverly uses "stone hitting stone", creating conditions for crushing large-size stones and laying the foundation for long-term continuous production.

[0040] In addition, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification without contradiction. Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and cannot be understood as limiting the present invention. Those skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
