Description

Technical Field

[0001] This utility model relates to the technical field of vertical shaft impact crushers, and in particular to a vertical shaft impact crusher with adjustable feed flow rate. Background Technology

[0002] Vertical shaft impact crusher, also known as vertical impact crusher or sand making machine, is a commonly used material crushing equipment in industries such as mining, building materials, and metallurgy.

[0003] In existing vertical shaft impact crushers, such as the vertical shaft impact crusher disclosed in patent CN217615066U, there are hopper assemblies, stone-on-iron crushing chamber assemblies, motors, transmission boxes, main shaft assemblies, and base assemblies. During operation, the stone enters the stone-on-iron crushing chamber through the hopper assembly. The impeller in the stone-on-iron crushing chamber rotates at high speed under the drive of the motor, transmission box, and main shaft assembly, striking the stone in the middle part composed of the upper and lower impact blocks, thereby crushing the stone.

[0004] However, the aforementioned crusher cannot adjust the feed flow rate. The stone can only enter the hopper assembly and the stone-on-iron crushing chamber assembly in sequence according to a fixed flow rate. When the crushing capacity of the impeller cannot keep up with the feed speed, it is easy to cause material jamming or incomplete crushing of the stone. If the feed speed is too slow, it will affect the production efficiency.

[0005] In conclusion, existing vertical shaft impact crushers still need improvement. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-2 As shown, the vertical shaft impact crusher with adjustable feed flow rate in this embodiment includes a casing 1, a cover 2, a receiving hopper 3, a discharge hopper 4, an impeller 5, a drive shaft 6, a collection trough 7, a flow rate adjustment component, and a drive motor 8.

[0029] The cover 2 is closable and mounted on the top of the housing 1. Specifically, a lifting cylinder 9 is provided on one or the opposite side (two opposite sides) of the housing 1. The cylinder body of the lifting cylinder 9 is fixedly connected to the side wall of the housing 1, and the upper end of the piston rod is fixedly connected to the cover 2. When the piston rod of the lifting cylinder 9 moves upward, it can open the cover 2; when the piston rod moves downward, it can close the cover 2, thereby facilitating the inspection and maintenance of relevant components inside the equipment.

[0030] The feeding hopper 4 is located on the top of the casing 1, the receiving hopper 3 is located on the top of the feeding hopper 4, the impeller 5 is rotatably located inside the casing 1 via the drive shaft 6, and the collecting trough 7 is fixedly located on the inner wall of the casing 1 and located outside the impeller 5.

[0031] The material to be crushed enters the equipment through the receiving hopper 3 and the discharge hopper 4 in sequence and falls onto the impeller 5. The impeller 5 has a feeding channel at its center and multiple vertical blade structures around it. After the material enters the impeller 5 through the feeding channel, it is thrown towards the collection trough 7 by the vertical blade structures on the outside. The material is crushed by the mutual collision between the vertical blade structures and the collection trough 7.

[0032] The drive motor 8 is located on both sides of the housing 1 and is connected to the drive shaft 6 via belt assemblies. Protective covers 10 are provided on both sides of the housing 1 at the outer side of the belt assemblies. The drive motor 8 is fixedly connected to the protective cover 10 via the motor base 11.

[0033] The belt assembly includes a drive pulley 12, a driven pulley 13, and a belt 14. The drive pulleys 12 are connected to the main shafts of the drive motors 8 on both sides. The driven pulleys 13 are located at the lower end of the transmission shaft 6. The drive pulleys 12 on both sides are connected to the driven pulleys 13 via belts 14, which are spaced apart vertically on both sides. During operation, the drive motors 8 on both sides and the belt assembly operate simultaneously, which helps to maintain the force balance of the transmission shaft 6 and prevents it from tilting to one side.

[0034] like Figure 3 As shown, the bottom of the casing 1 is provided with a discharge port 15, through which the crushed material is discharged.

[0035] like Figure 4As shown, the flow regulating component is located between the hopper 4 and the casing 1. The flow regulating component includes a receiving groove 16, a sleeve 17, a connecting frame 18, and adjusting bolts 19. The receiving groove 16 is located inside the casing 1 and below the hopper 4. The sleeve 17 is fixed inside the receiving groove 16 by bolts and its lower end is movably connected to the impeller 5. The connecting frame 18 is located outside the receiving groove 16. Multiple adjusting bolts 19 are spaced apart on the outside of the connecting frame 16. The upper end of the adjusting bolt 19 is locked to the casing 2 by a nut, and the lower end is also locked to the connecting frame 18 by a nut.

[0036] When it is necessary to adjust the feed flow rate, rotate the adjusting bolt 19 or nut to adjust the suspension height of the sleeve 17, thereby changing its depth into the impeller 5. The more the sleeve 17 extends into the impeller 5, the smaller the discharge space at its lower end and the less material is discharged; conversely, the less the sleeve 17 extends into the impeller 5, the larger the discharge space at its lower end and the more material is discharged. By adjusting and controlling the feed flow rate in the above manner, the material flow rate can be reasonably controlled according to the actual working conditions, preventing problems such as insufficient material crushing or insufficient production efficiency.

[0037] The advantage of using a suspended design for the sleeve 17 is that it facilitates maintenance or replacement. Simply open the cover 2; there is no need to enter the casing 1. Maintenance and replacement can be completed outside the equipment, which improves operational safety.

[0038] A sleeve 20 is provided on the outer side of the drive shaft 6. The outer side of the sleeve 20 is fixedly connected to the bottom of the housing 1 via a connecting seat 21. Both the upper and lower ends of the drive shaft 6 are rotatably connected to the sleeve 20 via bearings 22. Sealing end caps 23 are provided on the outer side of the bearings 22 at both ends to prevent dust accumulation. Figure 5 As shown, the upper end of the drive shaft 6 is fixedly connected to the impeller 5 by a pressure cap 24 and bolts 25.

[0039] like Figure 6 As shown, the top circumference of the housing 1 is provided with multiple connecting seats 26 at intervals, and the bottom circumference of the cover 2 is provided with multiple notches 27. A screw 28 is rotatably provided on the connecting seat 26. The screw 28 passes upward through the notch 27 and is locked by a nut 29. Through the cooperation of the screw 28 and the nut 29, the housing 1 and the cover 2 can be tightly connected to prevent material or dust leakage during crushing.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
