[0002] As an important raw material in the cement industry, the improvement of sandstone crushing and processing technology has become the focus of the industry. With the growth of market demand, cement companies have an increasing demand for sandstone aggregates, and the efficiency of sandstone crushing directly affects the operation of the entire production line. When the particle size of the sandstone crusher is too large, it is easy to cause problems such as roller deviation and large vibration of the reducer in the roller press, which seriously affects the stable operation of the roller press.

[0003] The sandstone crushing systems currently used mostly adopt a combination of sandstone crusher and oscillating roller feeder. When crushing large pieces of sandstone, if the sandstone contains fine materials, sand and soil, and has a high moisture content, the cone crusher will often be blocked, which seriously affects the hourly output of the sandstone crushing system and the normal operation of the sandstone crushing system.

[0004] It is further necessary to propose a sandstone discharge particle size processing device to avoid clogging of the cone crusher, thereby making the discharge particle size balanced and reducing wear during subsequent roller pressing operations. Utility Model Content

[0011] Preferably, side panels are fixedly installed on both sides of the top bracket, the side panels are designed with steel plates, and the side panels are welded and installed to the top bracket.

[0012] By fixing side plates on both sides of the top bracket respectively, designing the side plates with steel plates, and welding the side plates to the top bracket, the sandstone material injected onto the screen plate can be blocked by the side plates, thereby preventing the sandstone material from falling.

[0013] Preferably, there are two transmission rollers, and servo motors are installed at the rear ends of the two transmission rollers.

[0014] By installing servo motors on the rear ends of the two transmission rollers, the transmission rollers can be driven by the servo motors, thereby driving the conveyor belt to rotate.

[0017] Preferably, the top of the bottom bracket is welded to the bottom of the sieve plate, and the welding position between the top of the bottom bracket and the sieve plate corresponds to the welding position between the bottom of the top bracket and the sieve plate.

[0019] Preferably, the conveyor belt adopts a chain plate structure design, and the screen plate below the conveyor belt installation position is arranged in a horizontal direction.

[0020] By adopting a chain plate structure design for the conveyor belt and arranging the screen plate below the conveyor belt installation position in a horizontal direction, the sandstone material falling onto the screen plate can be scraped and transported by the scraper arranged on the rotating conveyor belt.

[0030] Specifically, the conveyor belt 3 is movably mounted on the inner side of the top bracket 5 through the transmission roller 2;

[0031] Among them, scrapers are fixedly installed on the outer wall of the conveyor belt 3 at equal intervals;

[0032] The side of the scraper away from the conveyor belt 3 does not contact the upper surface of the screen plate 1. The conveyor belt 3 is set and the conveyor belt 3 is movably installed on the inner side of the top bracket 5 through the transmission roller 2. At the same time, the outer wall of the conveyor belt 3 is fixed with scrapers at equal intervals. At the same time, the side of the scraper away from the conveyor belt 3 does not contact the upper surface of the screen plate 1. When performing specific operations, the sandstone material is injected from the tilted part of the front end of the screen plate 1, and the transmission roller 2 is driven by the servo motor to rotate counterclockwise. At this time, the conveyor belt 3 rotates counterclockwise synchronously, so that the sandstone material falling on the screen plate 1 is moved by the scraper set on the conveyor belt 3. The sandstone material falling onto the screen plate 1 is scraped and transported from left to right. During the transportation process, the fine material, sand and sewage in the sandstone material are screened through the screen plate 1. When the sandstone material is discharged from the rear end of the screen plate 1, the fine material, sand and water in the sandstone material are reduced. This avoids the blockage of the cone crusher when the sandstone material is crushed later, thereby making the discharge particle size more balanced, thus avoiding the blockage of the cone crusher, thereby making the discharge particle size balanced, and reducing the wear during the subsequent rolling operation.

[0033] Furthermore, side panels 4 are fixedly installed on both sides of the top bracket 5 , respectively. The side panels 4 are made of steel plates, and the side panels 4 are welded and installed to the top bracket 5 .

[0034] By fixing the side plates 4 on both sides of the top bracket 5, the side plates 4 are designed with steel plates, and the side plates 4 are welded and installed with the top bracket 5, the sandstone material injected on the screen plate 1 can be blocked by the side plates 4, thereby preventing the sandstone material from falling.

[0035] Furthermore, there are two transmission rollers 2, and servo motors are installed at the rear ends of the two transmission rollers 2.

[0036] By installing servo motors at the rear ends of the two driving rollers 2, the driving rollers 2 can be driven by the servo motors, thereby driving the conveyor belt 3 to rotate.

[0037] Furthermore, the front end of the sieve plate 1 is tilted and the tilted surface is welded and installed to the front end of the bottom of the top bracket 5 , and both sides of the sieve plate 1 are respectively welded and installed to the side plates 4 .

[0038] The front end of the sieve plate 1 is tilted and the tilted surface is welded to the bottom front end of the top bracket 5 to improve the stability of the sieve plate 1 during feeding, and the two sides of the sieve plate 1 are respectively welded to the side plates 4 to improve the stability of the connection between the side plates 4 and the sieve plate 1.

[0039] Furthermore, the top of the bottom bracket 6 is welded and installed to the bottom of the sieve plate 1 , and the welding position of the top of the bottom bracket 6 and the sieve plate 1 corresponds to the welding position of the bottom of the top bracket 5 and the sieve plate 1 .

[0040] The stability of the installation structure of the top bracket 5 is improved by welding the top of the bottom bracket 6 to the bottom of the sieve plate 1 and making the welding position of the top of the bottom bracket 6 and the sieve plate 1 correspond to the welding position of the bottom of the top bracket 5 and the sieve plate 1.

[0041] Furthermore, the conveyor belt 3 adopts a chain plate structure design, and the screen plate 1 below the installation position of the conveyor belt 3 adopts a horizontal layout.

[0042] By adopting a chain plate structure design for the conveyor belt 3 and arranging the screen plate 1 below the installation position of the conveyor belt 3 in a horizontal direction, the sandstone material falling on the screen plate 1 can be scraped and transported by the scraper arranged on the rotating conveyor belt 3. When the utility model is used, the sandstone material is injected from the tilted part of the front end of the screen plate 1, and the driving roller 2 is driven by the servo motor to rotate counterclockwise. At this time, the conveyor belt 3 rotates counterclockwise synchronously, so that the sandstone material falling on the screen plate 1 is scraped by the scraper arranged on the conveyor belt 3, so that the sandstone material falling on the screen plate 1 is transported from left to right, and in the process of transportation, the fine material, sand and sewage in the sandstone material are screened by the screen plate 1, so that when the sandstone material is discharged from the rear end of the screen plate 1, the fine material, sand and water in the sandstone material are reduced, so as to avoid the blockage of the cone crusher when the sandstone material is subsequently crushed, so as to avoid the blockage of the cone crusher after the material is discharged, so as to make the discharge particle size balanced, thereby reducing the wear in the subsequent roller pressing operation.
