Description

Technical Field

[0001] This utility model relates to the field of gypsum raw material processing technology, specifically to an automatic feeding and pre-crushing device for gypsum raw materials. Background Technology

[0002] Gypsum, an important raw material in construction, medical, and other fields, requires multiple processing steps, including feeding and crushing. Traditional gypsum raw material processing generally employs a separate operation mode of manual feeding or simple conveyor equipment combined with an independent crusher, which has significant drawbacks:

[0003] 1. Manual handling is labor-intensive, and intermittent feeding causes equipment to run idle; while ordinary conveyors lack a directional material guiding structure, which easily causes raw materials to scatter, and the connection between the feed inlet and the crusher is not tight, which easily causes material to spill.

[0004] 2. Conventional crushers use crushing gears with fixed tooth pitch, which cannot dynamically adjust the crushing gap according to the hardness of the raw materials. When encountering large pieces of gypsum or agglomerated materials, material jamming is likely to occur, causing the equipment to overload and stop, requiring manual intervention to clear the jamming, which affects the continuity of the production line.

[0005] 3. After crushing, gypsum powder is prone to caking in the material discharge area. Traditional inclined plate feeding relies on gravity flow and lacks a forced discharge mechanism, often requiring machine shutdown for unblocking.

[0006] Therefore, to address the aforementioned technical issues, an adjustable automatic processing system is designed to achieve efficient and continuous feeding of gypsum raw materials, adaptive pre-crushing, and controllable discharge, thereby improving the automation of the production line. Utility Model Content

[0007] The purpose of this invention is to provide an automatic feeding and pre-crushing device for gypsum raw materials to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding and pre-crushing treatment device for gypsum raw materials, comprising a frame, a conveyor, and a crusher, characterized in that: a conveyor and a crusher are respectively provided above the frame; the conveyor is inclined and a feeding frame is fixedly supported below it; two drive shafts are provided through both ends of the conveyor; a conveyor belt is sleeved on the outside of the two drive shafts; a feed inlet is provided at the bottom of the conveyor belt, and one end of the bottom drive shaft is connected to the output end of a drive motor; the drive motor is located on one side outside the conveyor; the end of the conveyor is located directly above the crushing feed inlet at the top of the crusher; a crushing motor is provided on one side outside the crusher; a drive belt is sleeved on the output end of the crushing motor; a crushing shaft is sleeved on the other end of the drive belt; the crushing shaft passes laterally through both ends of the crusher and is located below the crushing feed inlet; multiple sets of crushing gears are fixedly sleeved on the outside of the crushing shaft inside the crusher; a transmission chamber is provided inside the crusher; a pre-crushing control component is provided inside the transmission chamber; and a feeding component is provided below the multiple sets of crushing gears.

[0009] Preferably, the pre-crushing component includes a hydraulic cylinder disposed in the transmission chamber. A fixing frame is provided on the surface of the hydraulic cylinder and fixedly connected to the bottom of the transmission chamber. A push plate is fixedly connected to the output end of the hydraulic cylinder. The upper and lower ends of the push plate are in contact with the upper and lower surfaces inside the transmission chamber, and a crushing tooth is provided on the side surface of the push plate near the crushing gear.

[0010] Preferably, the left and right ends of the push plate are attached to the inner wall of the crusher, and its surface can cover the crushing feed inlet. By adjusting the distance between the crushing teeth and the crushing gear by the hydraulic cylinder, the size of the gypsum raw material pre-crushed can be effectively controlled.

[0011] Preferably, the feeding assembly includes a feeding plate, a vibrating motor, a vibrating spring, and a supporting column. The feeding plate is located below the crushing gear and is inclined, with one end extending through one side of the crusher to the outside. A supporting column is located inside the crusher to support and lift one end of the feeding plate. The other end of the feeding plate is engaged in the inner wall of the crusher and has a vibrating spring connected to its surface. A vibrating motor is located below the feeding plate for vibrating the feeding process.

[0012] Preferably, the conveyor is provided with baffle side plates on both sides.

[0013] Preferably, the conveyor belt surface is uniformly provided with multiple partition plates.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses an inclined conveyor in conjunction with a bottom feed inlet and a surface baffle plate, combined with side baffle plates on both sides, to achieve directional and continuous conveying of gypsum raw materials, effectively solving the problem of equipment idling caused by intermittent manual feeding. The funnel-shaped feed inlet at the bottom of the conveyor belt and the crushing feed inlet at the top of the crusher can quickly collect materials, avoiding the waste of raw materials and environmental pollution caused by material spillage in traditional split-type equipment.

[0016] 2. This utility model uses a hydraulically driven pre-crushing control component with a push plate and crushing teeth to dynamically adjust the gap between the crushing teeth and multiple sets of crushing gears, flexibly adapting to gypsum raw materials of different hardness or block size; when encountering large or agglomerated materials, the real-time displacement buffering effect of the crushing teeth can prevent material jamming, significantly reduce the risk of equipment overload shutdown, reduce the need for manual intervention, and ensure continuous operation of the production line.

[0017] 3. The coordinated design of the inclined feeding plate, vibrating motor, and vibrating spring forms a vibrating discharge channel below the crushing gear, effectively breaking up powder agglomerates; the vibrating spring provides elastic support, enhancing the high-frequency micro-vibration effect of the feeding plate, completely solving the clogging problem caused by powder moisture absorption and caking in the traditional gravity flow method, and ensuring smooth discharge.

[0023] like Figure 1-3 As shown, an embodiment of the automatic feeding and pre-crushing treatment device for gypsum raw materials is as follows: It includes a frame 1, a conveyor 2, and a crusher 8. The frame 1 serves as an integral support structure, with the inclined conveyor 2 and crusher 8 fixedly installed on its top. A feeding rack 3 is provided at the bottom of the conveyor 2 for reinforcement and support. A drive shaft 4 is provided through both ends of the conveyor 2, and a conveyor belt 5 is sleeved on the outside of the drive shaft 4. Multiple partition plates 51 are uniformly welded on the surface of the conveyor belt 5, and baffle side plates 21 are added on both sides to prevent material spillage during conveying. The drive shaft 4 at the bottom of the conveyor 2 is directly connected to the output shaft of the drive motor 7, and the drive motor 7 drives the conveyor belt 5 to run in a cycle. A funnel-shaped feed port 6 is opened at the bottom of the conveyor 2 to receive external gypsum raw materials, and the top outlet is suspended directly above the crushing feed port 9 in the crusher 8.

[0024] The crusher 8 is equipped with a crushing motor 10 on its side wall. The crushing motor 10 drives the crushing shaft 12 to rotate at high speed through the transmission belt 11. The crushing shaft 12 passes through the crusher 8 cavity laterally, and multiple sets of crushing gears 13 are fixedly sleeved on its surface to crush the gypsum raw materials. A transmission chamber 14 is provided below the crushing inlet 9, which contains a pre-crushing control component, including a hydraulic cylinder 141, a fixed frame 142, a push plate 143, and crushing teeth 144. The hydraulic cylinder 141 is fixed to the bottom of the transmission chamber 14 through the fixed frame 142. The piston rod end of its output end is connected to the push plate 143. The two sides of the push plate 143 slide against the inner wall of the crusher 8. The end face of the push plate 143 near the crushing gears 13 is welded with sawtooth-shaped crushing teeth 144. The hydraulic cylinder 141 can push the crushing teeth 144 to move horizontally, dynamically adjust its gap with the crushing gears 13, flexibly adapt to gypsum raw materials with different hardness or block size, and effectively control the material size of the pre-crushed gypsum raw materials.

[0025] Below the crushing gear 13, a feeding assembly is arranged, including a feeding plate 151, a vibrating motor 152, a vibrating spring 153, and a support column 154. One end of the inclined feeding plate 151 is supported by the support column 154 and extends to the outside of the crusher 8. The other end is embedded in the inner wall of the crusher 8 and connected to the vibrating spring 153. A vibrating motor 152 is installed at the bottom of the feeding plate 151 to effectively break up powder agglomerates and completely solve the clogging problem caused by powder moisture absorption and caking in the traditional gravity flow method, ensuring smooth discharge.

[0026] Working principle: First, the gypsum raw material falls into the bottom of the conveyor belt 5 through the feed inlet 6. The drive motor 7 drives the transmission shaft 4 to rotate, causing the conveyor belt 5 to rise in an inclined direction. The baffle plate 51 carries the raw material in sections, and the baffle side plate 21 constrains the material trajectory, realizing continuous directional conveying. After the raw material reaches the top of the conveyor belt 5, it falls directly into the crushing feed inlet 9 and enters the crusher 8. First, the pre-crushing control component: the hydraulic cylinder 141 pushes the crushing teeth 144 to the preset position, forming a fixed gap with the rotating crushing gear 13, and shears and crushes the raw material. When large or clumped materials are crushed, the material compresses the crushing teeth 144, generating reverse resistance. The hydraulic cylinder 141 automatically contracts to buffer and expand the crushing gap to avoid jamming. After the resistance is eliminated, the hydraulic cylinder 141 resets to maintain continuous crushing. By adjusting the stroke of the hydraulic cylinder 141, the distance between the crushing teeth 144 and the crushing gear 13 can be changed in real time to adapt to different raw material hardness or particle size. The crushed gypsum powder falls onto the inclined feeding plate 151. The vibration motor 152 vibrates at high frequency and transmits the vibration to the feeding plate 151 through the vibration spring 153, causing the powder to slide out under vibration.

[0027] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
