Description

Technical Field

[0001] This utility model belongs to the field of water-soluble fertilizer raw material arch breaking technology, specifically relating to a solid raw material arch breaking device. Background Technology

[0002] Water-soluble fertilizer raw materials have become an indispensable form of fertilizer in modern agriculture and industrial production due to their rapid dissolution and efficient absorption. However, during the storage and feeding process, these raw materials are prone to "arching" at the outlet of the raw material silo due to problems such as electrostatic adsorption between raw material particles, increased viscosity caused by humidity changes, and uneven pressure distribution at the bottom of the silo. Arching not only hinders the continuous feeding of raw materials, but also leads to equipment overload, raw material waste, and even production interruption, seriously affecting the stability and efficiency of automated production lines. Currently, common methods for breaking up arched raw materials for water-soluble fertilizers often employ a single physical action, such as using a vibration device or a pneumatic push rod to impact the inner wall of the raw material silo. However, these traditional devices generally suffer from limitations in structure and scope of action. For example, a vibration device, relying solely on periodic oscillations, cannot accurately target the arched area. While a pneumatic arch-breaking head can apply instantaneous impact force, it consumes a lot of energy and is easily affected by the moisture content of the raw material, making it ineffective in solving deep arching problems caused by excessive viscosity or uneven pressure distribution. Utility Model Content

[0003] In view of this, the present invention provides a solid raw material arch breaking device, which can achieve periodic vertical displacement through the arch breaking head during rotation, combined with the spiral disturbance of the stirring blades, to dynamically disturb and break the arched structure in multiple dimensions, effectively eliminate the flow dead corner at the bottom of the raw material silo, significantly improve the smoothness of material feeding, and avoid repeated arching problems caused by uneven pressure or humidity changes. It is suitable for water-soluble fertilizer raw materials with high viscosity.

[0004] To solve the above-mentioned technical problems, this utility model provides a solid raw material arch-breaking device, including a raw material silo and an arch-breaking mechanism set at the lower discharge port. The lower end of the arch-breaking mechanism is equipped with a valve. The arch-breaking mechanism includes a connecting pipe set between the raw material silo and the valve. A rotating ring is rotatably connected to the inner arc surface opening of the connecting pipe. A fixed frame is provided on the rotating ring. The fixed frame is composed of two cylinders, one horizontal and one vertical, and the whole is inverted T-shaped. An arch-breaking head is slidably connected in a rectangular groove set on the vertical cylinder of the fixed frame. The upper and lower ends of the upper cylinder of the arch-breaking head are both conical. A driving component for driving the arch-breaking head to move up and down is also provided in the connecting pipe. That is, the periodic vertical displacement is achieved by the arch-breaking head during rotation. Combined with the spiral disturbance of the stirring blades, the arch structure can be dynamically disturbed and destroyed in multiple dimensions, effectively eliminating the flow dead corner at the bottom of the raw material silo, significantly improving the smoothness of material discharge, and avoiding repeated arching problems caused by uneven pressure or humidity changes. It is suitable for water-soluble fertilizer raw materials with high viscosity.

[0005] The arch-breaking mechanism also includes stirring blades evenly arranged in a ring on the outer arc surface of the arch-breaking head, which stir the water-soluble fertilizer raw materials.

[0006] The arch-breaking mechanism also includes a worm gear ring located at the lower end of the outer arc surface of the rotating ring, and a worm is rotatably connected inside the connecting pipe. The worm meshes with the worm gear ring, thus achieving rapid transmission.

[0007] The arch-breaking mechanism also includes a geared motor located outside the connecting pipe. The output shaft of the geared motor is fixedly connected to one end of the worm gear, thus providing a drive source for the worm gear.

[0008] The drive assembly includes a lead screw rotatably connected to the bottom of a rectangular chute. The lead screw is threadedly connected to a threaded hole at the lower end of the arch-breaking head, thus providing a drive source for the arch-breaking head.

[0009] The drive assembly also includes a mounting cavity located in the middle of the transverse cylinder of the fixed frame. The lower end of the lead screw passes through a rotating hole set in the arc surface of the mounting cavity and has a bevel gear one at the end. A rotating rod is rotatably connected to the middle of the transverse cylinder of the fixed frame. A bevel gear two is located on the outer arc surface of the inner cavity of the mounting cavity. The bevel gear two meshes with the bevel gear one, thus providing a drive source for the lead screw.

[0010] The drive assembly also includes a bevel gear three located at one end of the rotating rod, and a bevel gear four located on the inner arc surface of the arch-breaking head. The bevel gear four meshes with the bevel gear three, thus providing a drive source for the rotating rod.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. When the water-soluble fertilizer raw material flows down through the raw material silo to the lower valve, the geared motor starts and drives the worm gear to rotate through the output shaft. When the worm gear rotates, it drives the rotating ring and its auxiliary mechanism to rotate around the axis of the connecting pipe through the worm wheel ring meshed with it. At this time, the arch-breaking head and its stirring blades rotate synchronously with the fixed frame, thereby agitating the material discharge point of the raw material silo. At the same time, the drive component drives the arch-breaking head to rise vertically along the rectangular slide of the fixed frame. After it rises to the dead point, the geared motor reverses, and all mechanisms rotate synchronously in the opposite direction, thereby driving the arch-breaking head to descend vertically along the rectangular slide of the fixed frame. Through the periodic vertical displacement achieved by the arch-breaking head during rotation, combined with the spiral disturbance of the stirring blades, the arch structure can be dynamically disturbed and destroyed in multiple dimensions, effectively eliminating the flow dead corner at the bottom of the raw material silo, significantly improving the smoothness of material discharge, and avoiding repeated arching problems caused by uneven pressure or humidity changes. It is suitable for water-soluble fertilizer raw materials with high viscosity. At the same time, the pointed conical end of the arch-breaking head can reduce the resistance when it moves up and down.

[0012] 2. The lead screw engages with the threaded hole at the lower end of the arch-breaking head, driving the arch-breaking head to rise vertically along the rectangular slide of the fixed frame. After reaching the dead point, the reduction motor reverses, and all mechanisms rotate synchronously in the opposite direction, thereby driving the arch-breaking head to descend vertically along the rectangular slide of the fixed frame, thus playing a lifting and lowering role for the arch-breaking head.

[0013] 3. Due to the fixed position of bevel gear four, when bevel gear three rotates synchronously with the fixed frame, it drives the rotating rod and bevel gear two to rotate synchronously. When bevel gear two rotates, it drives the lead screw to rotate through bevel gear one that meshes with it, thus achieving the function of rapid transmission. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides a device for breaking up arches in solid raw materials, such as... Figure 1-5As shown: The system includes a raw material silo 100 and an arch-breaking mechanism located at the lower discharge port. A valve 200 is located at the lower end of the arch-breaking mechanism. The arch-breaking mechanism includes a connecting pipe 300 between the raw material silo 100 and the valve 200. A rotating ring 301 is rotatably connected to the inner arc opening of the connecting pipe 300. A fixed frame 302 is provided on the rotating ring 301. The fixed frame 302 consists of two cylinders, one horizontal and one vertical, and is generally inverted T-shaped. An arch-breaking head 303 is slidably connected within a rectangular groove on the vertical cylinder of the fixed frame 302. An arch-breaking head 303 is located on the upper cylinder of the fixed frame 302. The lower ends are all conical. The connecting pipe 300 is also equipped with a drive assembly for driving the arch-breaking head 303 to move up and down. The arch-breaking mechanism also includes stirring blades 304 uniformly arranged in a ring on the outer arc surface of the arch-breaking head 303. The arch-breaking mechanism also includes a worm gear ring 305 located at the lower end of the outer arc surface of the rotating ring 301. A worm 306 is rotatably connected inside the connecting pipe 300. The worm 306 is meshed with the worm gear ring 305. The arch-breaking mechanism also includes a reduction motor 307 located outside the connecting pipe 300. The output shaft of the reduction motor 307 is fixedly connected to one end of the worm 306.

[0018] As the water-soluble fertilizer raw materials flow from the raw material silo 100 down to the lower valve 200, the reduction motor 307 starts, driving the worm gear 306 to rotate via the output shaft. When the worm gear 306 rotates, it drives the rotating ring 301 and its associated mechanism to rotate around the axis of the connecting pipe 300 via the worm wheel ring 305. At this time, the arch-breaking head 303 and its stirring blades 304 rotate synchronously with the fixed frame 302, thus agitating the material discharge point of the raw material silo 100. Simultaneously, the drive assembly drives the arch-breaking head 303 to rise vertically along the rectangular chute of the fixed frame 302. After reaching the dead center, the reduction motor 307 decelerates. When motor 307 reverses, all mechanisms rotate synchronously in the opposite direction, thereby driving the arch-breaking head 303 to descend vertically along the rectangular slide of the fixed frame 302. The arch-breaking head 303 achieves periodic vertical displacement during rotation. Combined with the spiral disturbance of the stirring blades 304, it can dynamically disturb and destroy the arched structure in multiple dimensions, effectively eliminating the flow dead corner at the bottom of the raw material silo 100, significantly improving the smoothness of material feeding, and avoiding repeated arching problems caused by uneven pressure or humidity changes. It is suitable for water-soluble fertilizer raw materials with high viscosity. At the same time, the pointed conical end of the arch-breaking head 303 can reduce the resistance when it moves up and down.

[0019] like Figure 1-3 As shown, the drive assembly includes a lead screw 400 rotatably connected to the bottom of a rectangular chute, and the lead screw 400 is threadedly connected to a threaded hole at the lower end of the arch-breaking head 303.

[0020] The lead screw 400 engages with the threaded hole at the lower end of the arch-breaking head 303, driving the arch-breaking head 303 to rise vertically along the rectangular slide of the fixed frame 302. After reaching the dead point, the reduction motor 307 reverses, and all mechanisms rotate synchronously in the opposite direction, thereby driving the arch-breaking head 303 to descend vertically along the rectangular slide of the fixed frame 302, thus playing a lifting and lowering role for the arch-breaking head 303.

[0021] like Figure 2-5 As shown, the drive assembly also includes a mounting cavity 401 located in the middle of the transverse cylinder of the fixed frame 302. The lower end of the lead screw 400 passes through a rotating hole provided in the inner arc surface of the mounting cavity 401 and is provided with a bevel gear 402 at the end. A rotating rod 403 is rotatably connected to the middle of the transverse cylinder of the fixed frame 302. A bevel gear 404 is provided on the outer arc surface of the rotating rod 403 located in the inner cavity of the mounting cavity 401. The bevel gear 404 meshes with the bevel gear 402. The drive assembly also includes a bevel gear 405 located at one end of the rotating rod 403. A bevel gear 406 is provided on the inner arc surface of the arch breaker 303. The bevel gear 406 meshes with the bevel gear 405.

[0022] Because the fourth bevel gear 406 is fixed, the third bevel gear 405 rotates synchronously with the fixed frame 302, which drives the rotating rod 403 and the second bevel gear 404 to rotate synchronously. When the second bevel gear 404 rotates, it drives the lead screw 400 to rotate through the first bevel gear 402 that meshes with it, thus achieving the function of rapid transmission.

[0023] The working principle of the solid raw material arch-breaking device provided by this utility model is as follows: When the water-soluble fertilizer raw material flows down to the valve 200 through the raw material silo 100, the reduction motor 307 starts and drives the worm gear 306 to rotate through the output shaft. When the worm gear 306 rotates, it drives the rotating ring 301 and its auxiliary mechanism to rotate around the axis of the connecting pipe 300 through the worm wheel ring 305 meshing with it. At this time, the arch-breaking head 303 and its stirring blades 304 rotate synchronously with the fixed frame 302, thereby stirring the material discharge point of the raw material silo 100. At the same time, due to the fixed effect of the fourth bevel gear 406, the third bevel gear 405 drives the rotating rod 403 and the second bevel gear 404 to rotate synchronously when it rotates synchronously with the fixed frame 302. When the second bevel gear 404 rotates, it drives the rotating rod 403 and the second bevel gear 404 to rotate synchronously through the bevel gear meshing with it. A screw 400 is rotated by a motor 402. The screw 400 engages with the threaded hole at the lower end of the arch-breaking head 303, driving the arch-breaking head 303 to rise vertically along the rectangular slide of the fixed frame 302. After reaching the dead point, the reduction motor 307 reverses, and all mechanisms rotate synchronously in the opposite direction, thereby driving the arch-breaking head 303 to descend vertically along the rectangular slide of the fixed frame 302. The periodic vertical displacement achieved by the arch-breaking head 303 during rotation, combined with the spiral disturbance of the stirring blades 304, can dynamically disturb and destroy the arched structure in multiple dimensions, effectively eliminating the dead flow corner at the bottom of the raw material silo 100, significantly improving the smoothness of material feeding, and avoiding repeated arching problems caused by uneven pressure or humidity changes. It is suitable for water-soluble fertilizer raw materials with high viscosity. At the same time, the pointed conical end of the arch-breaking head 303 can reduce the resistance when it moves up and down.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
