Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of feed batching, and particularly relates to a cleaning device for a feed batching scale. BACKGROUND

[0002] A batching scale refers to a weighing instrument that predefines a mass ratio and performs batching measurement on several substances in a weighed object. It can be applied to feed preparation and the batching measurement of multiple feeds. After batching is completed, cleaning is required to ensure the accuracy of the mass ratio in the next batching.

[0003] The existing feed batching scale, such as the feed batching scale disclosed in application No. CN202322556839.0, weighs and batches feed through the batching scale body, increases the uniformity of batching through the mixing roller rotatably connected inside the batching scale body, and sieves and discharges the feed through the equal-interval discharge grooves on the discharge plate. The feed can be sieved and discharged synchronously during discharge, and the sieve plate can be adjusted and replaced according to the size of the particles.

[0004] However, in actual use, the batching scale in the prior art lacks a cleaning mechanism. After batching is completed, the inside of the batching scale usually needs to be cleaned manually, which not only wastes manpower but also has complicated operation steps. In addition, the existing batching scale takes a long time to mix the layered feed when different feeds are added, and the upper and lower layers of feed are difficult to flow. Therefore, we propose a cleaning device for a feed batching scale to solve the above problems. UTILITY MODEL CONTENTS

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a cleaning device for a feed batching scale, which effectively solves the problem that the existing cleaning device for a feed batching scale lacks a cleaning mechanism, which leads to residues after batching and affects the accuracy of the mass ratio in the next batching. At the same time, the problem of poor flowability between the upper and lower layers of material in the existing batching scale, which leads to low mixing efficiency, is solved.

[0009] As the improvement of the scheme, the workbench is fixed with a fixing frame, a reduction motor is arranged on the fixing frame, and the reduction motor is arranged above the hopper.

[0010] As the improvement of the scheme, the cleaning mechanism comprises a stirring rod, a scraper, a rubber scraper and a fixing rod, the stirring rod is rotatably connected to the bottom of the fixing frame, one end of the stirring rod penetrates through the fixing frame and is connected to the output shaft of the reduction motor, the other end of the stirring rod is arranged in the hopper and is coaxially arranged with the hopper, the scraper is fixed on the side wall of the stirring rod, the rubber scraper is arranged on the outer wall of the scraper and is attached to the inner wall of the hopper, one end of the fixing rod is arranged on the scraper, and the other end of the fixing rod is arranged on the stirring rod.
