Gate discharging type quantitative bin for sow precision feeding

Abstract

The invention provides a gate discharging type quantitative bin for sow precision feeding. The gate discharging type quantitative bin for sow precision feeding comprises a quantitative bin body and atrapezoidal gate plate, wherein a discharging shaft tube U-shaped groove and a connecting hole are formed in the upper portion of the quantitative bin body, a long material flowing plate and a short material flowing plate which are oppositely arranged in a staggered mode are arranged on the lower portion of the quantitative bin body to form a vertical trapezoidal discharging port, and vertical guide strips are symmetrically arranged on the two sides in the quantitative bin body; and the top end of the trapezoidal gate plate is chamfered, a connecting rope connecting hole is formed in the upperportion, a material flowing port is formed in the middle, and guide grooves are formed in the two sides. The gate discharging type quantitative bin for sow precision feeding has the beneficial effects that under the closed state of the trapezoidal gate, materials fall into the quantitative bin, fall to the top end of the trapezoidal gate plate and are scattered by the gate plate, the shunting effect is achieved, and the possibility that the materials with high viscosity are adhered into blocks is reduced. When the trapezoidal gate is opened, due to the facts that the top end of the gate plateis chamfered, the cross section is narrow and long, the contact area with materials is small, and the trapezoidal gate plate is relatively small in mass compared with an original ball plug, in the lifting process, the self gravity is reduced, the gravity burden of the materials is avoided, and loads of a spiral shaft and a motor are greatly reduced; and besides, a material flowing hole is formedin the upper half part of the trapezoidal gate plate, so that materials on one side of the trapezoidal gate plate can flow to the other side through the material flowing hole in the lifting process, the flowability of the materials is improved, the residual quantity of the materials on the trapezoidal gate plate is extremely small, and the quantitative precision is improved.

Description

technical field [0001] The invention relates to the technical field of an automatic precision feeding system for sows, in particular to a gate-discharge type sow precision feeding quantitative bin. Background technique [0002] In the conventional automatic precision feeding system for sows, the feeding of the quantitative bin is completed by lifting the ball plug. The specific process: when the screw shaft motor rotates forward, the screw shaft above the quantitative bin pushes the material at a uniform speed so that the material falls to the quantitative bin. In this process, the single bearing on which the shaft head is wound with the connecting rope is in a slipping state, and the rope is not wound. The ball plug connected to the other end of the connecting rope is naturally hanging down and blocked at the discharge port due to its excessive mass. The material inside reaches the set quality, the load cell transmits the signal, the motor immediately stops forward rotation...

AI Technical Summary

Problems solved by technology

However, in actual work, it was found that since the feeding port of the screw shaft is directly facing the top of the ball plug, the material discharge is piled up on the ball plug, plus the mass of the ball plug itself, when the motor reverses and starts at the moment, the required power suddenly increases. Large, not only the power of the selected motor needs to be increased, but also the motor will be damaged when starting the forward and reverse frequently

Moreover, the contact area between the ball plug and the material is large. For materials with high viscosity, it is easy to stick to the ball plug and is not easy to fall, resulting in a certain error between the weighing weight and the actual output amount, which affects the quantitative accuracy.
