Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a small reagent feeder. Background Technology

[0002] During the production process, it is usually necessary to use feeding equipment to add raw materials. For large quantities of powder, commonly used equipment includes screw pumps and belt feeders; for small quantities of powder that need to be added precisely, special feeding equipment is required.

[0003] For example, patent document CN221055872U discloses a mechanical balance for convenient material feeding, including a base, a first column, a first crossbar, a weighing pan, a second column, a second crossbar, and a feeding component. The first column is fixed on the base, and the middle position of the first crossbar is hinged to the first column, with weighing pans installed on both sides of the first crossbar. The second column is also fixed on the base, and the top of the second column is fixedly connected to the second crossbar. A feeding component for adding materials to the weighing pan is slidably connected to the second crossbar. By setting up a feeding component to replace traditional manual feeding, the uniformity of the amount of material added each time is ensured. By setting up coarse feeding boxes and fine feeding boxes, the weighing efficiency is improved while preventing the weighing operation from failing due to over-feeding.

[0004] However, the feeding box of the device is set up separately, which increases the number of times the experimenter needs to touch the reagent when adding the material; moreover, the balance of the device needs to be judged by the naked eye, which is prone to error. Utility Model Content

[0005] The purpose of this invention is to provide a small reagent feeder to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6As shown, a small reagent feeder includes a base 1. A fixing mechanism is provided on the top of the base 1, and the fixing mechanism includes several support legs 301 fixedly connected to the top of the base 1. A material container 302 is fixedly connected to the top of the support legs 301. A feeding mechanism is provided at the bottom of the material container 302, and the feeding mechanism includes a fixing plate 501 fixedly connected to the bottom of the material container 302. Sliding sliders 502 are slidably connected to both sides of the fixing plate 501. The bottom of the material container 302... A gear 503 is rotatably connected to the slider 502. Both sides of the gear 503 are meshed with racks 508. The racks 508 are slidably connected to the slider 502. A connecting rod 504 is fixedly connected to the front side of the rack 508, and a first spring 505 is fixedly connected to the rear side of the rack 508. The other end of the first spring 505 is fixedly connected to the inner surface of the slider 502. The gear 503 has a first discharge port 506 and a second discharge port 507. The mesh diameter of the first discharge port 506 is large. With respect to the mesh diameter of the second discharge port 507, pressing the connecting rod 504 backward causes the corresponding rack 508 to move backward. Since the mesh diameter of the first discharge port 506 is larger than that of the second discharge port 507, different sliders 502 can be moved toward the gear 503 according to the required feeding speed, so that the rack 508 is engaged with the gear 503. Then, pressing the corresponding connecting rod 504 causes the rack 508 to move backward and compress the first spring 505. The movement of the rack 508 will cause the gear 503 to rotate. The rotation of the gear 503 will align the corresponding first discharge port 506 or second discharge port 507 with the discharge port 404. At this time, the raw material in the bucket 302 will fall into the container to control the feeding speed. The top of the base 1 is equipped with a feeding mechanism, and the fixed mechanism is equipped with a stirring mechanism. The top of the base 1 near the support leg 301 is equipped with an alarm mechanism, and the feeding mechanism away from the support leg 301 is equipped with an adjustment mechanism.

[0028] The dispensing mechanism includes a fixed block 201, which is fixedly connected to the top of the base 1. A lever 202 is rotatably connected to the fixed block 201. A limit shaft 203 is fixedly connected to one end of the lever 202 near the support leg 301. The other end of the lever 202 is slidably connected to another limit shaft 203. A connecting column 204 is rotatably connected to the limit shaft 203. A tray 205 is fixedly connected to the top of the connecting column 204. A weight of appropriate weight is placed on the tray 205 on the side away from the material bucket 302. Then, a beaker or other container of appropriate capacity is placed on the tray 205 on the other side. The tray 205 with the weight will descend due to gravity, while the tray 205 with the container will rise.

[0029] The fixing mechanism includes a feed pipe 303, which is fixedly connected to the top of the material barrel 302. The feed pipe 303 communicates with the inside of the material barrel 302, and the operator can add the material into the material barrel 302 through the feed pipe 303.

[0030] The mixing mechanism includes a motor 401, which is fixedly connected to the top of the material tank 302. The output end of the motor 401 is fixedly connected to a rotating shaft 402, and several mixing blades 403 are fixedly connected to the rotating shaft 402. A discharge port 404 is opened at the bottom of the material tank 302. When the motor 401 is started, the motor 401 drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the several mixing blades 403 to rotate, so as to mix the raw materials in the material tank 302 evenly and prevent clumping from affecting the feeding effect.

[0031] The alarm mechanism includes a column 601, which is fixedly connected to the top of the base 1. A battery is installed inside the column 601. An indicator light 602 is fixedly connected to the front of the connecting column 204 on the side near the material hopper 302. When the lever 202 is horizontal with the ground, the bottom of the connecting column 204 on the side where the container is placed will contact the top of the column 601. At this time, the battery built into the column 601 will supply current to the connecting column 204 through the connection between the connecting column 204 and the column 601, and the current will light up the indicator light 602.

[0032] The adjustment mechanism includes a button 701, which is slidably connected to the front side of a limiting shaft 203 on the side away from the material hopper 302. A pointer 8 is fixedly connected to the limiting shaft 203. A moving block 702 is fixedly connected to the rear side of the button 701. A shaped block 703 is slidably connected to the moving block 702. The shaped block 703 is slidably connected to the inner surface of the limiting shaft 203. A second spring 704 is fixedly connected to the top of the shaped block 703. The other end of the second spring 704 is fixedly connected to the limiting shaft 203. The surface of the lever 202 on the side away from the material hopper 302... A ratchet plate 705 is provided, and the bottom of the irregular block 703 is engaged with the ratchet plate 705. Pressing the button 701 causes the moving block 702 to move backward. When the moving block 702 moves backward, it will push the irregular block 703 upward and compress the second spring 704, so that the bottom of the irregular block 703 is disengaged from the groove on the ratchet plate 705. Then, after moving the limiting shaft 203 to the appropriate position and releasing the button 701, the second spring 704 will reset and re-engage the bottom of the irregular block 703 into the groove on the ratchet plate 705, thus completing the locking of the limiting shaft 203.

[0033] The lever 202 has several scale bars 9 on the front side of the end away from the material barrel 302. The pointer 8 on the limit shaft 203 will point to the scale marked on the scale bar 9 to achieve precise control of the weight.

[0034] Working principle: When using this device, the operator first adds the material into the material barrel 302 through the feed pipe 303, and then starts the motor 401. The motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives several stirring blades 403 to rotate, so as to stir the raw materials in the material barrel 302 evenly and prevent caking from affecting the feeding effect.

[0035] Then, according to the required amount of material to be added, place a weight of appropriate weight on the tray 205 on the side away from the material bucket 302, and then place a beaker or other container of appropriate capacity on the other side of the tray 205. The tray 205 with the weight will fall due to gravity, and the tray 205 with the container will rise.

[0036] Pressing the connecting rod 504 backward causes the corresponding rack 508 to move backward. Since the diameter of the mesh opening on the first discharge port 506 is larger than the diameter of the mesh opening on the second discharge port 507, different sliders 502 can be moved toward the gear 503 according to the required feeding speed, so that the rack 508 is engaged with the gear 503. Then, pressing the corresponding connecting rod 504 causes the rack 508 to move backward and compress the first spring 505. The movement of the rack 508 will drive the gear 503 to rotate. The rotation of the gear 503 will align the corresponding first discharge port 506 or second discharge port 507 with the feeding port 404. At this time, the raw material in the material bucket 302 will fall into the container to control the feeding speed.

[0037] During the feeding process, lever 202 will gradually become horizontal with the ground. When it reaches a horizontal state, the bottom of the connecting column 204 on the side where the container is placed will contact the top of the column 601. At this time, the battery built into the column 601 will supply current to the connecting column 204 through the connection between the connecting column 204 and the column 601. The current will light up the indicator light 602. When the indicator light 602 lights up, the operator needs to release the pressed connecting rod 504. At this time, the connecting rod 504 will rebound due to the characteristics of the first spring 505 and drive the gear 503 to rotate, re-closing the feeding port 404.

[0038] Pressing button 701 moves moving block 702 to the rear. When moving block 702 moves to the rear, it will push the irregular block 703 upward and compress the second spring 704, causing the bottom of the irregular block 703 to disengage from the groove on the ratchet plate 705. Then, the limiting shaft 203 is moved, and the pointer 8 on the limiting shaft 203 will point to the scale marked on the scale bar 9, realizing precise control of the weight. After moving to the appropriate position, release button 701, and the second spring 704 will reset and re-engage the bottom of the irregular block 703 into the groove on the ratchet plate 705, thus completing the locking of the limiting shaft 203.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
