Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to a quantitative feeding device. Background Art
[0002] Cement quantitative feeder is a device used to control and measure the input amount of cement in concrete mixing plant, ensuring the accuracy of raw material ratio in concrete production.
[0003] When in use, the belt-type cement quantitative feeder receives and transfers the cement raw materials inside the storage tank through a conveyor belt. The receiving hopper cannot be adjusted in position during use, and the specifications of the quantitative feeder cannot be adjusted after purchase. Sometimes, due to site restrictions and changes in the use environment, the fixed-position receiving hopper cannot effectively receive the cement inside the storage tank. There are limitations in the quantitative feeding of cement raw materials. For this reason, we propose a quantitative feeding device to solve the existing problems. Utility Model Content

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] like Figures 1-4 As shown, the utility model proposes a quantitative feeding device, including a motor 2, a quantitative feeder 3, a slider 6, a roller 10 and a latch 14. The quantitative feeder 3 includes a base 4 and a conveyor belt 8. The conveyor belt 8 is rotatably installed inside the base 4. A hopper 9 is provided above the conveyor belt 8. Sliders 6 are provided at both front and rear ends of the hopper 9. Guide rails 7 are provided at both front and rear ends of the base 4. The slider 6 is slidably installed on the outer wall of the guide rail 7. A mounting plate 5 is provided at the front end of the base 4. Positioning holes 13 are opened inside the mounting plate 5. The positioning holes 13 are equidistantly distributed inside the mounting plate 5. A latch 14 is provided on the rear side of the mounting plate 5. A travel hole 18 is opened inside the slider 6. Both ends of the latch 14 are respectively inserted into the positioning hole 13 and the travel hole 18. A spring 17 is sleeved on the outside of the latch 14. A limit ring 16 is sleeved on the outer wall of the latch 14. The front and rear ends of the spring 17 are connected to the limit ring 16 and the slider 6 respectively. A handle 15 is provided on the upper end of the latch 14.
[0020] Based on the implementation steps of Example 1: the hopper 9 slides on the guide rail 7 through the slider 6 and slides horizontally on the quantitative feeder 3. When the equipment is transferred or the use site is limited, the sliding hopper 9 is adjusted to the lower part of the output end of the corresponding cement raw material storage tank to receive the cement raw material. The cement raw material is received by the hopper 9 and transferred to the conveyor belt 8. The cement raw material is transferred by the conveyor belt 8, and the conveyed cement raw material is weighed by the weight measuring module of the quantitative feeder 3;
[0021] Before the slider 6 moves, the grip handle 15 drives the latch 14 to move, and the limiting ring 16 squeezes the spring 17. When the latch 14 moves out of the positioning hole 13, the slider 6 loses its fixation, and the movement of the slider 6 is realized. After the slider 6 moves to the specified position, the handle 15 is loosened, and the elastic force of the spring 17 acts on the limiting ring 16 and on the latch 14, which is inserted and positioned in the positioning hole 13 at the corresponding position, thereby realizing convenient positioning of the slider 6.
[0022] like Figures 1-4 As shown, the quantitative feeding device proposed by the present invention is compared with the embodiment 1, and this embodiment also includes: a roller 10 is rotatably installed inside the machine base 4, a motor 2 with an output shaft connected to one end of the roller 10 is provided at the front end of the machine base 4, and the outer wall of the roller 10 is provided with brush strips 12 distributed in a ring array, and the outer wall of the roller 10 is provided with scrapers 11 distributed in a ring array, and the scrapers 11 and the brush strips 12 are distributed at intervals, and a guide plate 1 is provided inside the machine base 4, and the guide plate 1 is located directly below the roller 10, and the guide plate 1 is inclined, and the lower part of the inclined surface faces the return direction of the conveyor belt 8.
[0023] In this embodiment, the motor 2 drives the rotating shaft to rotate, driving the brush bar 12 and the scraper 11 to rotate, and the return conveyor belt 8 is brushed in the opposite direction. The cement raw materials adhering to the conveyor belt 8 are brushed away by the brush bar 12 and the scraper 11, and output through the guide plate 1, thereby cleaning the conveyor belt 8 and preventing the accumulation of material on the outer wall of the conveyor belt 8 from affecting the accurate detection of the raw material transportation by the weighing module.
[0024] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
