Description

Technical Field

[0001] The utility model mainly relates to the technical field of sand making, and particularly relates to a sand making crusher with quantitative feeding. Background Art

[0002] A sand making crusher is a very common sand making mechanical equipment, which is widely used in industries such as machine-made sand and gravel materials, cement, refractories, and metallurgy. During operation, materials are fed into the feeding port of the sand making crusher, and the crushing mechanism inside the sand making crusher impacts, grinds, and crushes the materials to finally obtain small-grained sand and gravel.

[0003] Currently, the existing sand making crushers are inconvenient to use. During operation, they generally feed materials through a conveyor. The conveyor continuously feeds materials from the feeding port into the crusher for crushing. Since it takes time to crush the materials, a large amount of uncrushed materials will accumulate in the crusher, affecting the crushing effect. If this continues for a long time, it will also affect the service life of the crusher. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Summary of the Utility Model

[0005] 1. Technical problems to be solved by the utility model:

[0006] The utility model provides a sand making crusher with quantitative feeding to solve the technical problems existing in the above background art.

[0007] 2. Technical solutions:

[0008] To achieve the above object, the technical solution provided by the utility model is: a sand making crusher with quantitative feeding, including a crusher main body. A U-shaped frame is correspondingly installed outside the feeding port of the crusher main body. A feeding plate is correspondingly arranged at the lower part inside the U-shaped frame. One end of the feeding plate is correspondingly rotatably installed at the bottom end of the feeding port. A second telescopic cylinder is correspondingly rotatably installed at the bottom of the feeding plate. The other end of the second telescopic cylinder is correspondingly rotatably installed on the crusher main body. A chain conveyor is correspondingly arranged at the top of the crusher main body. The discharging port of the chain conveyor is correspondingly located above the feeding plate. A T-shaped baffle is correspondingly arranged on one side of the discharging port of the chain conveyor. First telescopic cylinders are correspondingly installed on the outer walls of the side baffles on both sides of the chain conveyor. Both sides of the baffle are respectively correspondingly connected to the telescopic ends of the two first telescopic cylinders. By using the baffle to block at the discharging port of the chain conveyor, the materials conveyed on the chain conveyor can be blocked.

[0009] Further, a retaining edge is provided by extending the bottom end of the baffle plate inward. When the first telescopic cylinder drives the baffle plate to retract, the retaining edge can correspondingly abut against the bottom of the chain plate of the chain plate conveyor.

[0010] Further, both sides of the U-shaped frame are correspondingly mounted on the main body of the crusher through connecting plates, and the size of the feeding plate corresponds to the inner frame size of the U-shaped frame; the width of the chain plate of the chain plate conveyor is smaller than the width of the feeding plate.

[0011] Further, two second telescopic cylinders are correspondingly provided at the bottom of the feeding plate. The two second telescopic cylinders are symmetrically arranged front and back and work synchronously in telescopic motion. One end of the second telescopic cylinder is correspondingly rotatably mounted at the bottom of the feeding plate, and the other end of the second telescopic cylinder is correspondingly rotatably mounted on the outer wall of the main body of the crusher. The second telescopic cylinder is used to control the feeding plate to rotate and tilt at a certain angle, so that the materials on the feeding plate slide into the main body of the crusher along the feeding port.

[0012] Further, a controller is correspondingly provided on the main body of the crusher. Both the first telescopic cylinder and the second telescopic cylinder are electrically connected to the controller, and the first telescopic cylinder and the second telescopic cylinder are controlled by the controller to work regularly and orderly.

[0013] 3. Beneficial effects:

[0014] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0015] The present utility model is reasonably designed. By providing a rotatable and tiltable feeding plate on one side of the feeding port of the main body of the crusher and cooperating with a baffle plate that is periodically blocked at the discharging port of the chain plate conveyor, during operation, the first telescopic cylinder can be extended for a certain period of time, so that the baffle plate is away from the discharging port of the chain plate conveyor for a certain period of time, so that the materials on the chain plate conveyor are quantitatively dropped onto the feeding plate. Then, the first telescopic cylinder is controlled to drive the baffle plate to retract, so that the discharging port of the chain plate conveyor is blocked again. At the same time, the second telescopic cylinder will extend to make the feeding plate rotate and tilt towards the feeding port of the main body of the crusher, so that the materials on it fall into the main body of the crusher for crushing. After that, the second telescopic cylinder will retract to make the feeding plate return to the horizontal state again. At this time, the baffle plate is away from the discharging port of the chain plate conveyor for a certain period of time again, feeding materials to the blanking plate, and feeding and crushing are carried out again. This process can be repeated in turn. This process realizes intermittent quantitative feeding and crushing, avoids a large amount of uncrushed materials from accumulating in the crusher, thus ensuring the crushing effect and extending the service life of the crusher; and the chain plate conveyor is arranged on the top of the main body of the crusher, which also saves space to a certain extent. The setting of its U-shaped frame and side baffle can also play a role in shielding, better avoiding the falling of materials. Its overall design is ingenious, flexible and convenient to use, and has strong practicability.

[0016] It should be noted that the structures not introduced in the present utility model are the same as the prior art or can be implemented by the prior art since they do not involve the design key points and improvement directions of the present utility model, and thus will not be elaborated herein.

[0025] Refer to the attached Figure 1-2 Referring to the attached drawings, a sand-making crusher for quantitative feeding in this embodiment includes a crusher main body 1. A U-shaped frame 3 is correspondingly installed outside the feeding port 101 of the crusher main body 1. A feeding plate 7 is correspondingly arranged at the lower part inside the U-shaped frame 3. One end of the feeding plate 7 is correspondingly rotatably installed at the bottom end of the feeding port 101. A second telescopic cylinder 8 is correspondingly rotatably installed at the bottom of the feeding plate 7. The other end of the second telescopic cylinder 8 is correspondingly rotatably installed on the crusher main body 1. A chain conveyor 2 is correspondingly arranged at the top of the crusher main body 1. The discharging port of the chain conveyor 2 is correspondingly located above the feeding plate 7. A T-shaped baffle plate 5 is correspondingly arranged on one side of the discharging port of the chain conveyor 2. First telescopic cylinders 6 are correspondingly installed on the outer walls of the side baffle plates 201 on both sides of the chain conveyor 2. Both sides of the baffle plate 5 are correspondingly connected to the telescopic ends of the two first telescopic cylinders 6 respectively. By using the baffle plate 5 to block at the discharging port of the chain conveyor 2, the materials conveyed on the chain conveyor 2 can be blocked.

[0026] Specifically, a baffle edge 501 is extended inward at the bottom end of the baffle plate 5. When the first telescopic cylinder 6 drives the baffle plate 5 to retract, the baffle edge 501 can correspondingly abut against the bottom of the chain of the chain conveyor 2.

[0027] Both sides of the U-shaped frame 3 are correspondingly installed on the crusher main body 1 through connecting plates 4. The size of the feeding plate 7 corresponds to the inner frame size of the U-shaped frame 3. The width of the chain of the chain conveyor 2 is smaller than the width of the feeding plate 7. The width of the baffle plate 5 corresponds to the width of the chain of the chain conveyor 2.

[0028] Two second telescopic cylinders 8 may be correspondingly arranged at the bottom of the feeding plate 7. The two second telescopic cylinders 8 are symmetrically arranged front and back and work synchronously in telescopic motion. One end of the second telescopic cylinder 8 is correspondingly rotatably installed at the bottom of the feeding plate 7. The other end of the second telescopic cylinder 8 is correspondingly rotatably installed on the outer wall of the crusher main body 1. By using the second telescopic cylinder 8 to control the feeding plate 7 to rotate and tilt at a certain angle, the materials on the feeding plate 7 can slide into the crusher main body 1 along the feeding port 101.

[0029] The crusher main body 1 is an existing device, and a crushing mechanism is correspondingly arranged therein. Since the existing crusher structure is already very mature and its internal structure is not the improvement point of this application, it will not be elaborated in detail here.

[0030] A controller is correspondingly arranged on the crusher main body 1. The first telescopic cylinder 6 and the second telescopic cylinder 8 are both electrically connected to the controller, and the first telescopic cylinder 6 and the second telescopic cylinder 8 are controlled by the controller to work regularly and orderly. During operation, the first telescopic cylinder 6 can be extended for a certain period of time, so that the baffle plate 5 is away from the discharge opening of the chain conveyor 2 for a certain period of time, such as about ten seconds, so that the materials on the chain conveyor 2 are quantitatively dropped onto the feeding plate 7. Then, the first telescopic cylinder 6 is controlled to drive the baffle plate 5 to retract, so that the discharge opening of the chain conveyor 2 is blocked again. At the same time, the second telescopic cylinder 8 will extend to make the feeding plate 7 rotate and tilt towards the feeding port 101 side of the crusher main body 1, so that the materials thereon fall into the crusher main body 1 for crushing. Then, the second telescopic cylinder 8 will retract to make the feeding plate 7 return to the horizontal state again. At this time, the baffle plate 5 is away from the discharge opening of the chain conveyor 2 for a certain period of time again, discharging materials onto the feeding plate 7, and feeding and crushing are carried out again. This process is repeated in turn, realizing intermittent quantitative feeding and crushing, avoiding a large amount of uncrushed materials from accumulating in the crusher, thus ensuring the crushing effect and extending the service life of the crusher; and the chain conveyor 2 is arranged on the top of the crusher main body 1, which also saves space to a certain extent. The setting of its U-shaped frame 3 and side baffle 201 can also play a shielding role, preferably avoiding material dropping. It should be noted that a pressure sensor can be embedded on the feeding plate 7, and the pressure sensor can be electrically connected to the controller, so as to more accurately control the telescopic time of the baffle plate 5 according to the weight of the materials on the feeding plate 7.
