During the storage and transportation of baking soda raw materials, the powdered raw materials solidify and block in the silo to form an arch, which makes it impossible to discharge the material normally. Therefore, a breaker is usually installed in the baking soda silo.

[0003] For example, in the prior art, a baking soda bin arch breaking device with a publication number of CN214650710U is provided. Through the coordination of the bin body, the cone cylinder, the discharge pipe, the electric control valve, the motor and the arch breaking assembly, when the device is in use, the meshing connection between the first gear and the second gear, and the rotation connection between the vertical rod and the vertical cylinder, the support rod can rotate while the vertical cylinder rotates axially, and then the material is stirred by the paddle.

[0004] However, the height of the paddle plate is fixed relative to the cone, so the stirring effect is limited. Moreover, the stirring of the material causes squeezing of the material to a certain extent, making the material easy to agglomerate and clump, which affects its use.

[0005] Therefore, the present application provides a baking soda bin arch breaking device to meet the demand. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a baking soda silo arch breaking device, which can stir the raw materials through a stirring rod, and at the same time, the vertical rod and the horizontal rod move up and down to stir the raw materials to improve the stirring effect. At the same time, the up and down reciprocating motion of the crushing block can crush the raw materials and reduce the agglomeration of the raw materials. The eccentrically installed cam is used to generate an exciting force to disperse the raw materials, thereby achieving the purpose of breaking the arch and facilitating discharging.

[0007] In order to solve the above technical problems, this application provides the following technical solutions:

[0008] A baking soda silo arch breaking device comprises a discharge hopper mounted on a side wall of the silo, a sleeve is concentrically arranged inside the discharge hopper, a stirring rod is arranged on the outer wall of the sleeve along the discharge direction, a connecting rod is passed through the inside of the sleeve, a breaking block facing the discharge direction is arranged on the top of the connecting rod, a spring is arranged between the connecting rod and the sleeve, a servo motor is mounted on the outside of the discharge hopper, a cam is connected to the part of the output end of the servo motor that passes through the side wall of the discharge hopper, the cam is located directly below the connecting rod, a gear is connected to the end of the stirring rod, a rack is connected to the side wall of the connecting rod, and the gear is meshed with the rack.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] In the above scheme, by setting a crushing block, a vertical rod and a horizontal rod, the connecting rod is squeezed during the rotation of the cam, and the spring is compressed and contracted, so that the connecting rod moves in the vertical direction inside the sleeve, and moves upward through the crushing block.

[0025] like Figure 1 , Figure 2 , Figure 3 A baking soda silo arch breaking device is shown, and the embodiment of the present application provides, comprising a discharge hopper 1 installed on the side wall of the silo, a sleeve 2 is concentrically arranged inside the discharge hopper 1, a stirring rod 201 is arranged on the outer wall of the sleeve 2 along the discharge direction, a connecting rod 3 is passed through the inside of the sleeve 2, a breaking block 301 facing the discharge direction is arranged on the top of the connecting rod 3, a spring 302 is arranged between the connecting rod 3 and the sleeve 2, a servo motor 4 is installed on the outside of the discharge hopper 1, and a cam 401 is connected to the part of the output end of the servo motor 4 that passes through the side wall of the discharge hopper 1, and the cam 401 is located directly below the connecting rod 3, a gear 202 is connected to the end of the stirring rod 201, and a rack 303 is connected to the side wall of the connecting rod 3, and the gear 202 is meshed with the rack 303;

[0026] When the servo motor 4 rotates, the cam 401 is driven to rotate. The cam 401 and the output shaft of the servo motor 4 are eccentrically arranged. The reciprocating cam 401 can generate vibration force, which is transmitted to the side wall of the discharge hopper 1, so as to promote the flow of materials in the discharge hopper 1 and loosen the materials, thereby achieving the purpose of breaking the arch.

[0027] During the rotation of the cam 401, the connecting rod 3 is squeezed, and the spring 302 is compressed and contracted, so that the connecting rod 3 moves vertically inside the sleeve 2 and moves upward through the crushing block 301. The tip of the crushing block 301 squeezes the material and destroys the static layer of the material, which has the effect of breaking the arch.

[0028] When the connecting rod 3 moves in the vertical direction inside the sleeve 2, it drives the rack 303 to move, and the gear 202 meshing with it drives the stirring rod 201 to rotate. The stirring rod 201 stirs the raw materials in the discharge hopper 1 to break and separate the raw materials to prevent agglomeration.

[0029] By utilizing the rebound force of the spring 302, after the cam 401 is separated from the connecting rod 3, the connecting rod 3 can move downward to move the crushing block 301 downward. During the downward movement of the rack 303, the stirring rod 201 changes its rotation direction. By reversing the direction of the stirring rod 201, a good stirring effect is achieved.

[0030] In this embodiment, Figure 2-Figure 4 As shown; the cam 401 is an eccentric wheel, and a 3 cm gap is set between the lowest point of the rotation track of the cam 401 and the bottom surface of the connecting rod 3;

[0031] The cam 401 does not keep continuous contact with the connecting rod 3 when rotating. The cam 401 can impact the connecting rod 3 during the rotation process, so as to impact the connecting rod 3 and the raw material at the wall position of the sleeve 2 through the vibration force, thereby enhancing its fluidity.

[0032] The outer wall of the sleeve 2 is provided with two groups of stirring rods 201 along the vertical direction, the stirring rods 201 and the sleeve 2 are orthogonally distributed, and the outer wall of the stirring rods 201 is provided with stirring blades 211;

[0033] The cooperation between the stirring rod 201 and the stirring blade 2011 can achieve a good stirring effect on the raw materials during the rotation of the stirring rod 201, thereby promoting the dispersion of the materials.

[0034] The crushing block 301 is composed of a cylindrical structure and a conical structure. The cylindrical part of the crushing block 301 is sleeved on the top of the sleeve 2, and the tip of the conical part of the crushing block 301 is vertically arranged upward.

[0035] The cylindrical part of the crushing block 301 effectively shields the top opening of the sleeve 2, thereby preventing the raw material from entering the interior of the sleeve 2. Meanwhile, the tip of the crushing block 301 has a good puncturing effect, thereby crushing the agglomerated materials.

[0036] A vertical rod 304 is connected to the bottom of the cylindrical part of the crushing block 301, and a horizontal rod 305 is arranged on the outer side wall of the vertical rod 304;

[0037] During the synchronous up-and-down reciprocating motion of the crushing block 301 and the connecting rod 3, the vertical rod 304 and the horizontal rod 305 are driven to reciprocate up and down, and the materials are stirred by the vertical rod 304 and the horizontal rod 305. The positions of the vertical rod 304 and the horizontal rod 305 are not kept fixed, and the up-and-down reciprocating motion process has a good stirring effect, which can reduce the agglomeration of the raw materials;

[0038] The angle between the horizontal bar 305 and the vertical bar 304 is 90°;

[0039] The crossbar 305 is distributed on both sides of the stirring rod 201. The crossbar 305 cooperates with the stirring rod 201 to promote good flow of materials and form a good dispersion effect.

[0040] A transmission shaft 402 is connected to one side of the cam 401. The transmission shaft 402 is coaxially arranged with the output end of the servo motor 4. One end of the transmission shaft 402 penetrates the side wall of the discharge hopper 1.

[0041] The vibration force generated when the cam 401 rotates can be transmitted to the side wall of the discharge hopper 1 through the transmission shaft 402, which has a good arch-breaking effect.
