Description

Technical Field

[0001] This utility model relates to the field of boron carbide production technology, specifically to a double-roll crusher that prevents material splashing. Background Technology

[0002] Boron carbide, also known as black diamond, is typically a grayish-black powder. It is one of the three hardest known materials and is used in tank armor, bulletproof vests, and many industrial applications.

[0003] In the production of boron carbide, it is sometimes necessary to use a double roll crusher to crush the lumpy boron carbide raw material into granules for subsequent production.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When the existing double roll crusher crushes boron carbide raw materials, boron carbide raw material fragments will splash out from the feed port of the double roll crusher, and the splashed boron carbide raw material fragments may cause injury to the user; 2. When the existing double roll crusher is in use, it generally uses an electric hydraulic cylinder to drive the crushing rollers to adjust the distance between the two crushing rollers and crush the blocky boron carbide raw materials into particles of the required size. The transmission mechanism of ordinary crushing rollers is generally a drive wheel and a belt. Long-term driving of the crushing rollers back and forth will cause wear between the belt and the drive wheel, which can easily cause the belt to loosen or even fall off. Utility Model Content

[0005] The purpose of this invention is to provide a double-roll crusher that prevents material splashing, thereby solving the problems mentioned in the background section. To achieve the above objective, this invention provides the following technical solution: a double-roll crusher that prevents material splashing, comprising a crushing assembly, an adjusting assembly installed on the inner wall of the crushing assembly, and a feeding assembly installed on the top of the crushing assembly.

[0006] The crushing assembly includes a housing with movable holes and sliding grooves at both the front and rear ends. A first support plate is installed at the rear end of the housing, and a first reduction motor is installed on the top of the first support plate. A first drive wheel is installed at the output end of the first reduction motor. A plurality of first transmission belts are attached to the outer wall of the first drive wheel, and a first driven wheel is attached to the inner wall of the first transmission belts. A first connecting rod is installed at the front end of the first driven wheel, and a first crushing roller is installed on the outer wall of the first connecting rod. A material hopper is installed on the inner wall of the housing, and a discharge pipe is installed at the bottom of the housing.

[0007] The adjustment assembly includes a first mounting plate and a second mounting plate mounted to the bottom of the housing. A second geared motor is mounted on one side of the second mounting plate, and a threaded rod is mounted on the output end of the second geared motor. A sliding rod is mounted on one side of the first mounting plate, and a sliding plate is threaded onto the outer wall of the threaded rod. A fixed plate is mounted on the top of the sliding plate, and a second support plate is mounted on the front end of the fixed plate. A third geared motor is mounted on the top of the second support plate, and a second drive wheel is mounted on the output end of the third geared motor. A plurality of second transmission belts are attached to the outer wall of the second drive wheel, and a second driven wheel is attached to the inner wall of the second transmission belts. A second connecting rod is mounted on the rear end of the second driven wheel, and a second crushing roller is mounted on the outer wall of the second connecting rod.

[0008] The feeding assembly includes an inclined feeding pipe installed on the top of the housing, a feeding hopper installed on the top of the inclined feeding pipe, and a baffle and a chain installed on the inner wall of the feeding hopper.

[0009] More preferably, the outer walls of the first driving wheel and the first driven wheel are provided with several annular grooves whose internal dimensions are consistent with the external dimensions of the first transmission belt, and the front end of the housing is rotatably mounted with a first connecting rod.

[0010] More preferably, the box body is provided with support legs at the four corners of the bottom, and rectangular holes are provided at the top and bottom of the box body.

[0011] More preferably, the fixed plates are symmetrically distributed about the vertical center line of the sliding plate, and the front end of the fixed plate is rotatably mounted with a second connecting rod. The outer walls of the second driving wheel and the second driven wheel are each provided with several annular grooves whose internal dimensions are consistent with the external dimensions of the second transmission belt.

[0012] More preferably, a sliding plate is slidably mounted on the outer wall of the slide rod, and the slide rods are symmetrically distributed about the vertical center line of the sliding plate.

[0013] More preferably, the inclined feed pipe is inclined from bottom to top and to the left, and the baffle is inclined from right to left and downward.

[0014] More preferably, the inner wall of the inclined feed tube is provided with a plurality of chains evenly and equidistantly distributed from front to back.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, by means of a crushing assembly and an adjusting assembly, when it is necessary to adjust the distance between the two crushing rollers, the second reduction motor is activated. The second reduction motor drives the sliding plate, fixed plate, second support plate, third reduction motor, second drive wheel, second transmission belt, second driven wheel, second connecting rod, and second crushing roller to move left and right via a threaded rod. The distance between the second crushing roller and the first crushing roller can be adjusted according to the crushing requirements.

The relative distance between the second drive wheel, second transmission belt, and second driven wheel remains unchanged, which can improve the stability of the double-roll crusher during use.

[0017] In this invention, when using a double-roll crusher to crush lumpy boron carbide raw materials, the lumpy boron carbide raw materials are added into the feed hopper via the feeding assembly. The boron carbide raw materials pass through the gap between the baffle and the inclined feed pipe and pass through several chains into the housing. The first crushing roller and the second crushing roller crush the lumpy boron carbide raw materials. When boron carbide raw material fragments are splashed, the chain curtain composed of the inclined feed pipe, the baffle, and several chains can block the splashed boron carbide raw material fragments, avoiding injury to the user and improving the safety of the double-roll crusher during use.

[0036] The usage and advantages of this utility model: The working process of this anti-material-splashing double-roll crusher is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, firstly, the second reduction motor 203 is started.

Then, the first reduction motor 105 and the third reduction motor 209 are started. The first reduction motor 105 drives the first connecting rod 109 and the first crushing roller 1010 through the first drive wheel 106, first transmission belt 107, and first driven wheel 108. 10 rotates clockwise, and the third reduction motor 209 drives the second connecting rod 2013 and the second crushing roller 2014 to rotate counterclockwise through the second driving wheel 2010, the second transmission belt 2011 and the second driven wheel 2012. Then, the blocky boron carbide raw material to be crushed is added into the feed hopper 302. The blocky boron carbide raw material passes through the gap between the baffle 303 and the inclined feed pipe 301 and passes through several chains 304 into the box 101. When the blocky boron carbide raw material falls onto the first crushing roller 1010 and the second crushing roller 2014, the first crushing roller 1010 and the second crushing roller 2014 crush the blocky boron carbide raw material. After crushing, the boron carbide raw material is discharged through the hopper 1011 and the discharge pipe 1012.
