[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. The amount used in feed is very small but the effect is significant. Feed additives are raw materials that must be used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. In the feed processing industry, weighing and feeding of granular raw materials and auxiliary materials is an important link. The feed processing machinery factory provides feeding and conveying equipment including belt conveyors, screw conveyors, pneumatic conveying systems, etc. They are responsible for transferring feed additives from storage locations to mixing or processing areas. They are characterized by large addition amounts. For small amounts of additives, especially additives in granular form, it is difficult to evaluate the retention amount in the conveying pipeline for long-distance transportation. In order to accurately put a small amount of additives into a stirring mixer, this application document provides a granular raw material weighing and feeding device. Utility Model Content

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:
[0029] See also Figure 1-6 As shown, the utility model is a weighing and feeding device for granular raw materials, comprising a storage bin 1, a first horizontal conveyor 2, a second horizontal conveyor 3 and a frame 4. The frame 4 comprises four columns 41 and a rectangular frame 42. The two side surfaces of the rectangular frame 42 in the length direction are connected to the four columns 41 as a whole through four cross bars 43. The upper end of the column 41 is fixedly connected to the outer wall of the storage bin 1. The storage bin 1 is fixedly mounted on the upper end of the frame 4. Four weighing sensors 5 are mounted on the rectangular frame 42 of the frame 4. The second horizontal conveyor 3 is mounted on the four weighing sensors 5. Four first hanging ears 11 are fixed to the outer wall of the storage bin 1. Four second hanging ears 21 are fixed to the first horizontal conveyor 2. The storage bin 1 and the first horizontal conveyor 2 are connected by four double-hook hanging rods 8. The two hooks of the double-hook hanging rod 8 are connected to the first hanging ear 11 and the second hanging ear 21 respectively. The conveyor belt of the first horizontal conveyor 2 is evenly provided with material troughs 22 arranged along its width direction. A vertically arranged discharge pipe 12 is provided at the lower end of the storage bin 1. The discharge pipe 12 at the lower end of the storage bin 1 is placed directly above the belt of the first horizontal conveyor 2, and the distance between them is controlled to reduce the overflow from the discharge pipe 12.
[0030] The entire loading process is to start the first horizontal conveyor 2 and take away the granular feed additives falling from the discharge pipe 12 when its belt rotates. The granular raw materials are placed on the trough 22 and the belt surface, and then fall onto the belt of the second horizontal conveyor 3 below. The weight sensor 5 measures the weight of the falling granular raw materials. When the weight of the single-added additive reaches a certain value, the first horizontal conveyor 2 stops rotating. When the additive needs to be added, the second horizontal conveyor 3 starts. The output end of the second horizontal conveyor 3 is located at the feeding window on the mixer. After the additive is completely transported away, it stops rotating to complete the single-time feeding of the additive. The storage bin 1, the first horizontal conveyor 2 and the second horizontal conveyor 3 of the utility model are arranged vertically in sequence and transported in alternating directions. The overall occupied area is small, and it is suitable for being arranged on one side of the feed mixer for the filling of auxiliary materials.
[0031] The second horizontal conveyor 3 is also provided with a conical hopper 31. The conical hopper 31 is connected and fixed to the frame of the second horizontal conveyor 3 through two fixed connecting plates 32. The distance between the lower end of the conical hopper 31 and the surface of the conveyor belt of the second horizontal conveyor 3 is not less than the average diameter of the granular raw material. A discharge slot 33 is provided on a side wall of the lower end of the conical hopper 31 located in the conveying direction of the conveyor belt of the second horizontal conveyor 3. By installing the conical hopper 31 on the second horizontal conveyor 3, the amount of additives that can be added at a time is increased, and at the same time, the influence of airflow on the falling process of the granular raw material is reduced, thereby reducing waste.
[0032] In order to improve the controllable accuracy of the feed output by the first horizontal conveyor 2, a sleeve 7 is slidably matched on the outer wall of the discharge pipe 12. The sleeve 7 encloses the feed on the outside of the discharge pipe 12, and the bottom surface of the sleeve 7 contacts the surface of the conveyor belt of the first horizontal conveyor 2. After the conveyor belt of the first horizontal conveyor 2 passes through the discharge pipe 12, only the feed is output in the trough 22, which reduces the single-turn output of the first horizontal conveyor 2, which is beneficial to the weighing accuracy of the second horizontal conveyor 3 below. In addition, the sleeve 7 is provided, and there is no need to control the appropriate distance between the lower end of the discharge pipe 12 and the conveyor belt of the first horizontal conveyor 2 by replacing the double hook hanging rod 8 of different lengths, which reduces the difficulty of assembly between the storage bin 1 and the first horizontal conveyor 2.
[0033] Among them, a paddle discharger 6 is fixed to the inner wall of the discharge pipe 12. The paddle discharger 6 includes a cylinder 61 that matches the inner wall of the discharge pipe 12. A vertical plate 62 arranged radially is fixed to the inner wall of the cylinder 61. A row of paddles 63 is fixed to one side of the vertical plate 62 by bolts. A row of red plates 64 are fixed to both surfaces of the paddles 63. A conical cylinder 65 that matches the inner bottom surface of the storage bin 1 is fixed to the upper end of the cylinder 61. When the belt of the first horizontal conveyor 2 rotates, the lower ends of a row of paddles 63 contact the belt, and when the lower ends of the paddles 63 slide over the trough 22, a vibration is generated, and the paddles 63 drive the red plates 64 to stir the granular raw materials in the discharge pipe 12, and the granular raw materials move downward accordingly. The voids generated in the granular raw materials in the discharge pipe 12 during the discharge process are avoided, and the smooth discharge is effectively guaranteed.
