[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0028] like Figure 1-5 As shown, the utility model proposes a storage hopper feeding device for baking soda production, including a storage hopper 1 body, and a control valve 112 is installed at the discharge port 11 below the storage hopper 1 body. The control valve 112 can adopt a plug valve structure. By controlling the opening and closing of the control valve 112, the amount of material entering the feed box 2 can be effectively controlled under the cooperation of the weighing detection of the weighing component 221. The discharge port 11 is connected to the feed box 2, and a feeder 3 is provided below the feed box 2. The feeder 3 adopts a horizontally arranged conveyor belt structure. The feed box 2 is arranged to be through-connected from top to bottom and a discharge port is provided on the right side. The top of the feed box 2 is connected to the discharge port 11, and a side plate 21 that can slide up and down is vertically provided at the discharge port, and a bottom plate 22 is horizontally provided below the feed box 2. In the present device, a material cavity with an upper opening is formed between the front and rear side walls of the feeding box 2, the push plate 4 on the left, the side plate 21 on the right and the bottom plate 22, so that under the action of the weighing assembly 221 installed above the bottom plate 22, the material in the material cavity can be weighed and detected to complete the quantitative control of material feeding.

[0029] Specifically, the front and rear side walls of the material discharge port are provided with first slide grooves 201, and the front and rear ends of the side panels 21 are vertically slidably clamped in the corresponding first slide grooves 201. When the side panels 21 slide up and down in the first slide grooves 201, the movement of the side panels 21 is more stable. The side panels 21 are connected to the lifting drive assembly on the feed box 2. The lifting drive assembly includes a screw rod 532 and a motor 531. The screw rod 532 is vertically slidably installed on the feed box 2 and is connected to the power of the motor 531. A moving block is threadedly sleeved on the screw rod 532, and the moving block is fixedly connected to the side panel 21. When the motor 531 drives the screw rod 532 to rotate, the moving block drives the side panel 21 to slide up and down, thereby realizing the opening and closing control of the right material discharge port.

[0030] The left side of the bottom plate 22 is rotatably connected to the feed box 2, and a support driving assembly for driving the bottom plate 22 to flip is provided on the feed box 2. The support driving assembly includes a first hydraulic cylinder 51, the tail of the first hydraulic cylinder 51 is hinged to the left side below the feed box 2, and the piston rod of the first hydraulic cylinder 51 is hinged to the bottom of the bottom plate 22 in an upward tilt. The first hydraulic cylinder 51 drives the bottom plate 22 to rotate and swing, and cooperates with the opening and closing of the side plate 21 to realize the rapid unloading operation of the material in the feed box 2.

[0031] A push plate 4 is vertically movable on the left side of the feed box 2, close to the front and rear side walls of the feed box 2 and the top surface of the bottom plate 22. A horizontal driving assembly for driving the push plate 4 to move left and right is provided on the left side of the feed box 2. The horizontal driving assembly includes a second hydraulic cylinder 52, which is horizontally installed on the left side of the feed box 2. The piston rod of the second hydraulic cylinder 52 extends into the feed box 2 and is fixedly connected to the push plate 4. The extension and retraction of the second hydraulic cylinder 52 can drive the push plate 4 to slide left and right, thereby effectively scraping off the materials adhered to the front and rear side walls of the feed box 2 and the bottom plate 22.

[0032] A first scraper assembly is provided on the right side of the push plate 4. The first scraper assembly includes a first scraper 6 horizontally arranged close to the right side wall of the push plate 4. A second chute 40 is vertically opened on the right side wall of the push plate 4. A protrusion 61 on the left side of the first scraper 6 is slidably clamped in the second chute 40, wherein the second chute 40 is a T-shaped groove and the protrusion 61 is a T-shaped block, which can make the first scraper 6 move up and down more stably. Guide blocks 62 are fixedly provided on the front and rear end surfaces of the first scraper 6. Guide grooves 202 inclined to the lower right are symmetrically opened on the front and rear side walls of the feed box 2. The guide blocks 62 are slidably arranged in the corresponding guide grooves 202. When the push plate 4 moves to the right to scrape off the residual material on the feed box 2, under the guiding action of the guide groove 202, the first scraper 6 will slide up and down along the second chute 40 along the side wall of the push plate 4, thereby scraping off the residual material adhering to the push plate 4 from top to bottom, so as to clean the push plate 4.

[0033] In addition, a scraper 7 is hingedly connected to the side of the first scraper 6 away from the push plate 4, and the blade on the left side of the scraper 7 is tilted downward and abuts against the right side wall of the push plate 4. A tension spring 71 is fixedly connected between the scraper 7 and the upper first scraper 6. Under the elastic force of the tension spring 71, the blade of the scraper 7 is effectively in contact with the side wall of the push plate 4. As the first scraper 6 moves downward, the scraper 7 can effectively clean the hard materials adhering to the push plate 4 with its sharp blade.

[0034] A second scraper assembly is provided on the upper inner side of the material discharge port to cooperate with the side plate 21. The second scraper assembly includes a second scraper fixed horizontally on the inner side of the material discharge port close to the upper left side wall of the side plate 21. The second scraper can be designed as a triangular prism with the tip facing downward. As the lifting drive assembly drives the side plate 21 to open upward, the second scraper can effectively scrape off the material adhering to the side plate 21.

[0035] When the utility model is used, a fixed amount of material can be introduced into the feed box 2 through the detection of the weighing assembly 221 and the linkage of the control valve 112 below the storage hopper 1. The control motor 531 drives the screw 532 to rotate and work with the first hydraulic cylinder 51, so that the side plate 21 moves up to open the discharge port and cooperates with the flipping and tilting of the bottom plate 22, so that the material is quickly discharged and falls on the feeder 3, completing the discharge operation. When the second hydraulic cylinder 52 extends and pushes the push plate 4 to move rightward, the push plate 4 can effectively scrape off the materials adhered to the front and rear side walls of the feed box 2 and the bottom plate 22, and the first scraper 6 cooperates with the scraper 7 to move downward to scrape off the adhered materials on the push plate 4; for the materials adhered to the side plate 21, the second scraper can scrape them off by the side plate 21 itself moving upward, so that the device can effectively clean the materials adhered to the inner wall of the feed box 2, thereby effectively avoiding the problems of the adhered materials in the feed box 2 being hardened and blocked, and the feeding amount being inaccurate.
