Description

Technical Field

[0001] This utility model relates to the field of stone processing equipment technology, and in particular to a stone shaping device for sand making. Background Technology

[0002] Stone shaping machines, also known as vertical shaft impact crushers, work on the principle of a high-speed rotating impeller that accelerates and throws raw materials smaller than 60mm, forming a high-speed material flow. This material flow is ejected at a certain speed from three evenly distributed channels of the impeller, colliding with naturally falling stones to form a vortex crushing chamber. Within this chamber, the material undergoes two or more impacts, friction, and grinding, and is finally discharged from the lower discharge port. Its specific structure can be referenced in the existing technology disclosed in Chinese Patent Publication No. CN213726972U, which describes a vertical shaft impact crushing and sand making equipment.

[0003] Currently, impellers are mainly driven by motors and transmission structures. Most transmission structures are belt and pulley assemblies. However, the lack of adjustment mechanisms in existing motor installations makes belt assembly, disassembly, and maintenance inconvenient.

[0004] Based on this, in order to improve the ease of operation of the transmission structure, we propose a stone shaping device for sand making. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the inconvenience of assembling, disassembling and maintaining belts, and to propose a stone shaping device for sand making.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a stone shaping device for sand making, including: A feeding hopper mounted on a bracket and a crushing shell fixed to the feeding hopper; An impeller is rotatably connected inside the crushing shell, and the shaft of the impeller extends into the interior of the feeding bin. At least one drive assembly is installed on the side of the feeding bin, and the drive assembly is used to drive the shaft to rotate. The feeding hopper has a feeding channel and a mounting cavity, the shaft extends into the mounting cavity, and the feeding channel is connected to the crushing shell.

[0007] Furthermore, the drive assembly includes a frame fixed to the side of the discharge hopper, and the frame is connected to the mounting cavity; A motor base is slidably connected above the frame, and a motor is fixedly installed above the motor base. The shaft end of the motor extends to the inner side of the frame, and a transmission structure is provided between the shaft end of the motor and the shaft.

[0008] Furthermore, a U-shaped rod is movably inserted into the upper side of the frame, and the two ends of the U-shaped rod are fixedly connected to the side of the motor base; The frame is also rotatably connected to a lead screw, which is threadedly connected to the middle of the U-shaped rod.

[0009] Furthermore, a slot is provided at the upper end of the frame, and a bolt and nut assembly that is clamped between the motor base and the bottom of the frame is slidably connected in the slot.

[0010] Furthermore, the transmission structure includes a first pulley fixed to the end of the motor shaft and a second pulley fixed to the outside of the shaft, with the first pulley and the second pulley connected by a belt drive.

[0011] Furthermore, a fan blade is fixed to the outer wall of the shaft located inside the mounting cavity, and an exhaust port is opened at the end of the frame.

[0012] Furthermore, the material discharge hopper is located below the installation cavity and has an inspection port, the outside of which is connected to a cover plate by fasteners.

[0013] The present invention provides a stone shaping device for sand making, which has the following advantages: By setting a feeding channel and an installation cavity inside the feeding hopper, the drive component and the impeller shaft can be easily connected.

[0016] 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.

[0017] Reference Figure 1-5 As one embodiment of this utility model, it discloses a stone shaping device for sand making. Specifically, the shaping device includes a feeding bin 1 installed on a support and a crushing shell 2 fixed on the feeding bin 1. An impeller 3 is rotatably connected inside the crushing shell 2. The shaft 31 of the impeller 3 extends into the interior of the feeding hopper 1. During operation, the stone to be shaped is added from the crushing shell 2. The stone will enter the center of the impeller 3 along the guide hopper above the crushing shell 2. When the impeller 3 rotates at high speed, it will throw the stone out by centrifugal force to impact the inner wall of the crushing shell 2. At the same time, it will collide with the subsequently thrown stone, so that the material is subjected to two or more impacts, friction and grinding crushing actions inside the crushing shell 2, ultimately achieving the purpose of stone shaping. Of course, the above-mentioned structures of the broken shell 2 and impeller 3 have been disclosed in the prior art. This solution does not improve the above structure, so it will not be described in detail. At least one drive assembly 4 is installed on the side of the feeding bin 1, and the drive assembly 4 is used to drive the shaft 31 to rotate. The feeding bin 1 has a feeding channel 11 and a mounting cavity 12, the shaft 31 extends into the mounting cavity 12, and the feeding channel 11 is connected to the crushing shell 2.

[0018] Specifically, in this embodiment, there are two feeding channels 11, which are symmetrically arranged on both sides of the mounting cavity 12. Of course, in this embodiment, the mounting cavity 12 is not connected to the crushing shell 2. After the stone is shaped, it can fall down along the feeding channel 11 to complete the feeding operation.

[0019] In some embodiments, the drive assembly 4 of the present invention includes a frame 41 fixed to the side of the unloading bin 1, and the frame 41 is connected to the mounting cavity 12; A motor base 42 is slidably connected above the frame 41, and a motor 43 is fixedly installed above the motor base 42. The shaft end of the motor 43 extends to the inner side of the frame 41, and a transmission structure 44 is provided between the shaft end of the motor 43 and the shaft 31. Obviously, in this embodiment, a straight groove should also be opened above the frame 41, and the shaft end of the motor 43 slides in the straight groove to achieve position adjustment.

[0020] Based on the above embodiments, the transmission structure 44 in this embodiment includes a first pulley 441 fixed on the shaft end of the motor 43 and a second pulley 442 fixed on the outside of the shaft 31. The first pulley 441 and the second pulley 442 are driven by a belt 443.

[0021] Of course, the pulley is circumferentially locked by a key block and fixed by a set screw, so as to facilitate subsequent disassembly; Furthermore, while the above embodiment uses one drive component 4 as an example, this embodiment can also use two drive components 4 for synchronously driving the shaft 31, as detailed below. Figure 1 As shown, the two drive components 4 are symmetrically arranged. At this time, two second pulleys 442 should be stacked on the shaft 31, and the two motors 43 should rotate synchronously. This can improve the driving stability of the shaft 31.

[0022] Specifically, in this embodiment, a U-shaped rod 45 is movably inserted into the upper side of the frame 41, and the two ends of the U-shaped rod 45 are fixedly connected to the side of the motor base 42; The side of the frame 41 is also rotatably connected to a lead screw 46, which is threadedly connected to the middle of the U-shaped rod 45.

[0023] In other words, in this embodiment, when the transmission structure 44 needs to be replaced or maintained, the linear movement of the U-shaped rod 45 can be controlled by rotating the lead screw 46, thereby further realizing the lateral position control of the motor 43. When the motor 43 moves toward the side of the shaft 31, the belt 443 is in a slack state. The user can then easily remove the pulley and then remove the belt 443. When the new belt 443 is replaced, the motor 43 can be driven to move in reverse. Once the belt 443 is tightened, the driving operation can be carried out.

[0024] Preferably, in this embodiment, a slot 47 is provided at the upper end of the frame 41, and a bolt and nut assembly 48 that is clamped between the motor base 42 and the bottom of the frame 41 is slidably connected in the slot 47.

[0025] In this embodiment, the linear position of the motor base 42 is fixed by using the guide and fixing method of the bolt and nut assembly 48. Specifically, the bolt passes through the motor base 42 and the frame 41 and slides in the slot 47, and the end of the bolt is fixed by the nut. During adjustment, the nut is first loosened, and the motor base 42 is adjusted to the predetermined position by rotating the screw 46. After the adjustment is completed, the bolt and nut are locked to complete the position fixing of the motor base 42.

[0026] Considering that during the processing, the internal temperature of the crushed outer shell 2 will rise due to the continuous impact of the internal stones, and the continuous rotation of the belt 443 will also generate temperature, in order to cool down the belt 443 and ensure its durability, in this embodiment, the outer wall of the shaft 31 located inside the mounting cavity 12 is also fixed with a fan blade 32, and the end of the frame 41 is also opened with an exhaust port 49. The fan blade 32 blows air towards the pulley to dissipate heat and achieve the purpose of cooling. Of course, an air inlet can also be reserved in the feeding bin 1 at the position of the fan blade 32. A filter screen is installed at the air inlet to prevent dust and ensure air circulation. In addition, the exhaust port 49 can also serve as a maintenance window for the first pulley 441. When replacing the belt 443, the user can disassemble and install the first pulley 441 through the exhaust port 49.

[0027] It should be noted that, in this embodiment, the material discharge hopper 1 is located below the mounting cavity 12 and is provided with an inspection port 13. The inspection port 13 is used to disassemble and maintain the second pulley 442. Of course, in order to cover and protect the inspection port 13, in this embodiment, a cover plate 14 is connected to the outside of the inspection port 13 by fasteners. The fasteners can be bolts.

[0028] In summary, by setting a feeding channel 11 and an installation cavity 12 inside the feeding bin 1, the drive assembly 4 and the shaft 31 of the impeller 3 can be easily connected. During use, the position of the motor base 42 can be adjusted by the lead screw 46, thereby adjusting the tension of the belt 443. When the belt 443 is in a loose position, it can be disassembled and replaced. After replacement, the motor base 42 can be reset and the belt 443 can be tightened. The overall structure design is simple and can effectively improve the ease of maintenance of the transmission structure 44.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
