Abstract

The invention relates to a method for improving the weighing precision of a stock tower in a farm, wherein when the stock tower needs to input/output materials (such as material receiving or feeding), a control system firstly closes an electric gate valve, then starts a conveyor to run for a period of time until the conveyor is automatically stopped after emptying feed in a flexible connection range, so that the flexible connection is in a free state, the dragging effect of the conveyor on the stock tower is eliminated, and the weighing data at the moment is automatically recorded by the system. After the material feeding/discharging is completed, the system again records the weighing data in the above manner. The difference between the two is the weight of the material in/out. By the method, the accurate weighing value of the starting point of the material feeding/discharging can be obtained, so that the accuracy of the material feeding/discharging amount in the material tower weighing system is ensured, and the calculation precision is improved.

Background
Along with the development of aquaculture, the intensive livestock farm all adopted the higher automatic feed system of degree of automation at present, set up the material tower outside the house, carry out automatic feed as required to the interior stockline of house through the conveyer (adopt flexible screw conveyer or pipe chain conveyer usually). When a certain amount of feed is left in the feed tower, a feed tank truck needs to be arranged to feed and supplement the feed into the feed tower.
More and more farms are beginning to pay attention to the weighing of material towers, and some material tower weighing systems are also introduced. The feeding tower is additionally provided with the weighing system, so that the storage amount of the feed in the feeding tower can be monitored in real time, and the dynamic consumption rate of a feed line in a shed can be measured and calculated. On one hand, the feed can be reasonably fed by the feed tanker, on the other hand, the feed conversion ratio can be calculated in an auxiliary manner, and accurate feeding can be carried out under the condition of limited feeding.
However, in practical application, the weighing precision of the material tower is not high, and the application effect of the material tower is seriously influenced. Factors influencing the weighing of the material tower are many, but the influence of the conveyor at the outlet of the material tower is undoubtedly the largest. And referring to application experiences of other industries, the flexible connection is adopted at the joint of the bottom of the material tower and the conveyor, so that the influence of the symmetrical weight of the conveyor is reduced as much as possible, but the effect is very little.

(1-3) according to a weighing sensor at the bottom of the material tower, recording weighing data A by a controller;
(1-4) carrying out material tower material receiving, and recording weighing data B by the controller after the material tower material receiving is finished;
(1-5) calculating the difference value of the weighing data A and the weighing data B, namely the weight of the material received by the material tower;
the material tower feeding step comprises the following steps:
(2-1) the controller sends out an instruction for closing the electric gate valve, and the electric gate valve is closed;
(2-2) the controller sends an instruction for starting the conveyor, the conveyor is operated until materials in a flexible connecting piece between the electric gate valve and the conveyor are emptied, and the conveyor is stopped to operate;
(2-3) according to the weighing sensor at the bottom of the material tower, the controller records weighing data C;
(2-4) the controller sends out an instruction for opening the electric flashboard valve, and the electric flashboard valve is opened; simultaneously sending an instruction for operating the conveyor to operate the conveyor;
(2-5) feeding the material tower, repeating (2-1) - (2-3) after the feeding of the material tower is finished, and obtaining weighing data D;
and (2-6) calculating the difference value of the weighing data C and D, namely the weight of the material fed by the material tower.
When the material tower needs to enter/exit materials (such as material receiving or feeding), the control system firstly closes the electric gate valve, then starts the conveyor to run for a period of time until the conveyor is automatically stopped after the feed in the flexible connection range is emptied, so that the flexible connection is in a free state, the dragging effect of the conveyor on the material tower is eliminated, and the weighing data at the moment is automatically recorded by the system.
After the feeding/discharging is finished, the system records the weighing data again, and opens the electric gate valve to ensure the feeding of the material tower.
By adopting the method for improving the weighing precision of the material tower in the farm, the accurate weighing value of the starting point of the material feeding/discharging can be obtained, so that the accuracy of calculating the material feeding/discharging quantity by a material tower weighing system is ensured, and the calculation precision is improved.
