Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, and specifically relates to a crushing device. Background Technology

[0002] Crushing equipment is widely used in agriculture, food processing, pharmaceuticals, and chemicals, primarily to crush raw materials or solid materials into granules or powder to meet the needs of subsequent production or processing. Traditional crushing equipment typically uses a fixed feeding mechanism for material delivery. While this design is relatively simple, it has certain limitations in practical use.

[0003] In existing technologies, both mechanical feeding equipment and manual feeding methods are widely used. Therefore, crushers typically require two feed hoppers: one vertical for mechanical feeding and one horizontal for manual feeding. Mechanical feeding equipment, such as conveyor belts or screw pumps, can efficiently and continuously feed materials into the crusher. However, when connecting the equipment, the feed inlet position must be fixed and precisely installed; otherwise, feeding difficulties or leaks may occur. Manual feeding, on the other hand, relies on operators directly feeding materials into the feed inlet. While this method is suitable for small-batch or temporary crushing operations, the operation is easily affected by the height and angle of the feed inlet, especially for operators of different heights, where feeding becomes particularly inconvenient.

[0004] Furthermore, the feeding mechanism of traditional crushing devices has significant shortcomings in terms of versatility and operational flexibility. For example, the angle and direction of the feed inlet are usually fixed and cannot be adjusted according to specific application requirements. This not only affects feeding efficiency but may also lead to material accumulation or blockage during the conveying process, thereby reducing the overall performance of the crushing device. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a crushing device that is compatible with both mechanical and manual feeding mechanisms, eliminates the need for multiple feeding hoppers, and features an adjustable angle, thereby improving the applicability and working efficiency of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crushing device includes a crushing chamber, a chamber door is installed on one side of the crushing chamber, and a feeding mechanism is installed on one side of the chamber door. The feeding mechanism includes a rotatable top hopper and a bottom material pipe. A sleeve is provided at the bottom end of the rotatable top hopper, and a cylindrical tube head is provided at the top end of the bottom material pipe. The sleeve is movably nested on the outside of the cylindrical tube head. The sleeve and the cylindrical tube head are used for the movable connection between the rotatable top hopper and the bottom material pipe.

[0008] Furthermore, a bolt is installed through the sleeve head and the cylindrical tube head, and the sleeve head and the cylindrical tube head are fixed by screwing the bolt together. The bolt is used to fix the tilt angle of the rotatable top hopper.

[0009] Furthermore, a manual feeding plate is provided on one side of the top of the rotatable top hopper, which is used for manual feeding and receiving of materials.

[0010] Furthermore, the upper surface of the cylindrical tube head is provided with a feed window, which is used for materials to enter the crusher chamber.

[0011] Furthermore, the inside of the silo door is provided with a feed inlet, and the bottom end of the bottom material pipe is provided with a connecting flange, which is fixedly installed on the outside of the feed inlet by screws.

[0012] Furthermore, it also includes a support frame, with the crusher chamber fixed to the top of the support frame. A motor is installed on the inside of the support frame, and the motor and the drive wheel of the crusher chamber are connected by a V-belt drive.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This crushing device features a rotatable top hopper, allowing its tilt angle to be adjusted according to actual needs. This solves the problem of traditional crushing devices having fixed feed inlets, requiring multiple feed hoppers, and being unable to adapt to various feeding methods. When using mechanical feeding, the rotatable top hopper can be adjusted to a vertical position, facilitating precise docking between the feeding equipment and the feeding mechanism, ensuring continuous and efficient feeding. When using manual feeding, the tilt angle of the top hopper can be adjusted according to the operator's height, reducing the difficulty of manual feeding, improving operational flexibility and convenience, and meeting the needs of different working conditions.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1 , Figures 3-5 As shown, a crushing device includes a crushing chamber 102. A chamber door 104 is installed on one side of the crushing chamber 102, and a feeding mechanism 103 is installed on one side of the chamber door 104. The feeding mechanism 103 includes a rotatable top hopper 105 and a bottom material pipe 106. A sleeve 152 is provided at the bottom end of the rotatable top hopper 105, and a cylindrical tube head 161 is provided at the top end of the bottom material pipe 106. The sleeve 152 is movably nested on the outside of the cylindrical tube head 161. The sleeve 152 and the cylindrical tube head 161 are used for the movable connection between the rotatable top hopper 105 and the bottom material pipe 106. The rotatable top hopper 105 can rotate around the axis of the cylindrical tube head 161 through the sleeve 152, so as to adjust the angle of the rotatable top hopper 105 according to the feeding method, while ensuring that the material smoothly enters the crushing chamber 102 for crushing.

[0027] like Figure 1 , Figures 3-5 As shown, a bolt 107 is installed through the sleeve head 152 and the cylindrical tube head 161, and the sleeve head 152 and the cylindrical tube head 161 are fixed by screwing the bolt 107 together. The bolt 107 is used to fix the tilt angle of the rotatable top hopper 105. By screwing the bolt 107 together, the angle of the rotatable top hopper 105 can be fixed in a vertical or tilted state to meet the needs of mechanical or manual feeding. During the adjustment process, the operator can loosen the bolt 107 to allow the rotatable top hopper 105 to rotate freely.

[0028] like Figure 4 and Figure 8 As shown, a manual feeding plate 151 is provided on one side of the top of the rotatable top hopper 105. The manual feeding plate 151 is used for manual feeding and receiving of materials. The surface of the manual feeding plate 151 is a smooth structure, which is used for receiving materials when they are manually fed. The side edge of the manual feeding plate 151 is slightly higher than the top of the rotatable top hopper 105 to prevent materials from slipping off the sides during manual feeding and to improve the convenience of operation.

[0029] like Figures 1-6 As shown, a feed window 162 is provided on the upper surface of the cylindrical tube head 161, which is used for materials to enter the crusher chamber 102.

[0030] like Figures 2-6 As shown, the inside of the silo door 104 is provided with a feed inlet 141, and the bottom end of the bottom material pipe 106 is provided with a docking flange 163. The docking flange 163 is fixedly installed on the outside of the feed inlet 141 by screws.

[0031] like Figure 1 As shown, it also includes a support 101, a crusher chamber 102 fixed to the top of the support 101, a motor installed on the inner side of the support 101, and the motor and the drive wheel of the crusher chamber 102 are connected by a V-belt drive.

[0032] The working principle of this utility model is as follows:

[0033] When feeding the feeding mechanism 103 using mechanical feeding (conveyor belt, screw conveyor pump, etc.), tighten or loosen bolt 107, then rotate the rotatable top hopper 105, as per reference. Figure 7 This makes the rotatable top hopper 105 vertical and tightens the bolt 107. Then, the discharge port of the mechanical feeding device is directly above the rotatable top hopper 105. The mechanical feeding device sends the material through the rotatable top hopper 105, the bottom material pipe 106, and the inlet 141 into the crusher chamber 102 for crushing, thus achieving the crushing of the material.

[0034] When manually feeding the feeding mechanism 103, loosen bolt 107, then rotate the rotatable top hopper 105, as per reference. Figure 8 The rotatable top hopper 105 is tilted, and the tilt of the rotatable top hopper 105 is adjusted according to the height of the feeding personnel to facilitate the personnel to place the material on the manual feeding plate 151. Then, the bolts 107 are screwed and tightened to fix the tilt of the rotatable top hopper 105, and the material can be fed. After passing through the rotatable top hopper 105, the bottom material pipe 106, and the feed port 141, the material is sent into the crusher chamber 102 for crushing, thus realizing the crushing of the material.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
