[0020] like Figure 1-Figure 3 As shown,
[0021] As an optional embodiment, an improved sand making machine crushing cylinder includes a first cylinder body 1 and a second cylinder body 2 for crushing materials, a clamp assembly 5 is arranged between the first cylinder body 1 and the second cylinder body 2, the clamp assembly 5 includes a first clamp ring 51 and a second clamp ring 52, a second connecting member 12 is detachably connected between the first clamp ring 51 and the second clamp ring 52, the second connecting member 12 includes a first fixing seat 9 and a second fixing seat 10, the first fixing seat 9 is fixedly connected to the end of the second clamp ring 52, the second fixing seat 10 is fixedly connected to the end of the first clamp ring 51, a first through hole is opened in the first fixing seat 9 and the second fixing seat 10, and a second fastener 11 is installed in the first through hole; the inner walls of the first clamp ring 51 and the second clamp ring 52 are opened with an inclined groove 511, and the inclined groove 511 is provided with a first positioning ring 13 and a second positioning ring 14, the first positioning ring 13 is fixedly connected to the first cylinder body 1, and the second positioning ring 14 is fixedly connected to the second cylinder body 2.
[0022] Specifically, the two cylinders are detachably connected, namely the first cylinder 1 and the second cylinder 2, and the two cylinders are detachably connected through a clamp assembly 5. After the two cylinders are butt-jointed, the clamp assembly 5 is located at the connection between the two cylinders to fix the two to ensure the stability of the connection; in addition, the first fixing seat 9 is connected to the second clamp ring 52 as a whole, and the second fixing seat 10 is connected to the first clamp ring 51 as a whole. The way of connecting as a whole can be welding, and the first fixing seat 9 and the second fixing seat 10 are located at the first clamp ring 51 and the second clamp ring In the inclined groove 511 inside 52, in the process of connecting the first fixing seat 9 and the second fixing seat 10 and bringing them close to each other through the second fastener 11, the inner walls of the first clamping ring 51 and the second clamping ring 52 are tightly attached to the surface of the first positioning ring 13 and the second positioning ring 14.

When the retaining ring is retracted, the distance between the retaining ring and the cylinder is gradually shortened, so the bevel groove 511 is matched with the bevel of the limiting ring 15, and the limiting ring 15 is further abutted to generate radial force and axial force so that its side abuts against the limiting ring 15, the cylinder and the positioning ring surface, thereby achieving axial and radial sealing.

The fixed connection method is welding. The inner and outer sleeves 18 are selected for installation, and the outer sleeve 18 is subsequently sleeved on the surface of the inner sleeve 17 to position the end faces of the first cylinder 1 and the second cylinder 2 to prevent the two from offsetting during the subsequent connection and fixing process.
[0026] The first cylinder 1 and the second cylinder 2 both include a first curved plate 101 and a second curved plate 102, and a first connecting member 4 is detachably connected between the first curved plate 101 and the second curved plate 102. For each cylinder, two semicircular curved plates are selected to form a complete cylinder. If a certain curved plate in the cylinder is deformed later, the single curved plate can be replaced without replacing the entire cylinder.
[0027] The two arc plates are connected by a first connecting member 4, and the following structure is designed about the first connecting member 4: the first connecting member 4 includes a first strip plate 6 and a second strip plate 7 arranged at the connection between the first arc plate 101 and the second arc plate 102, the first strip plate 6 is fixedly connected to the first arc plate 101, and the second strip plate 7 is fixedly connected to the second arc plate 102, and a third through hole is opened on the first strip plate 6 and the second strip plate 7, and a first fastener 8 is installed in the third through hole, wherein the first strip plate 6 and the first arc plate 101, and the second strip plate 7 and the second arc plate 102 are all welded, and the first strip plate 6 and the second strip plate 7 are connected as a whole by the first fastener 8, so that the first arc plate 101 and the second arc plate 102 are spliced into a whole; a side plate 3 is installed on one side of the first cylinder 1, and the side plate 3 blocks one side of the first cylinder 1, and the subsequent crushing shaft passes through the side plate 3 and enters the cylinder to carry out crushing work on the subsequent materials flowing into the cylinder.
