Description

Measuring device for measuring weight and water content of separated crops

Technical Field

The utility model relates to the technical field of agricultural machinery automation, in particular to a measuring device for measuring the weight and the water content of separated crops.

Background

With the advancement of technology, farmers have long changed the traditional way of farming by using various agricultural machines. In the eight-door agricultural machinery, a threshing machine for threshing various crops is also indispensable, and the feeding and threshing part links of the conventional threshing machine can realize mechanization instead of manual operation. In recent years, most farmers sell threshed crop seeds along with the threshing work, and the work of weighing the crops along with the threshing work is quite troublesome. Particularly, the operation of selling grains and checking weights is very inconvenient for rare farmers of motor balances in mountainous areas with complex and remote terrain in China, and the farmers cannot check weighing results of the motor balances when the weighing results are questioned. Furthermore, the traditional manual weight checking method is adopted, a mechanical platform scale or an electronic platform scale is adopted for weighing, crop seeds separated from the thresher are manually bagged and repeatedly checked by placing the seeds in a bag of the platform scale during working, the repeated bagging and weight checking workload is large, the labor is consumed, the weighing error is large, and the total weight total price of the crop is calculated in a troublesome manner; the existing automatic weighing equipment is limited by the conditions of high price, large volume, dependence on a power grid and a heavy air compressor, and the existing automatic weighing equipment has the defects that a charging door and a discharging door of the existing automatic weighing equipment are driven by cylinders, the action sensitivity of an outdoor cylinder in cold winter is delayed seriously or even the existing automatic weighing equipment is difficult to work normally, in addition, moisture is mixed in gas generated by the air supply compressor due to low outdoor temperature, the gas is easy to be frozen to form ice and then blocks an air supply pipeline to influence the normal work, the existing automatic weighing equipment is not suitable for a series of severe working environments such as field operation, frequent movement, sudden outdoor temperature difference change and the like of the threshing machine, and the existing automatic weighing equipment cannot be matched with the threshing machine at all.

In current agricultural production, the existing grain threshing work mode cannot realize dynamic tracking and measurement of the water content percentage of crop grains separated by a threshing machine, and farmers and grain buyers cannot know the water content percentage value of the separated crop grains in real time while threshing. The percentage value of the water content in the total weight of the separated grains cannot be calculated after the threshing is finished, and farmers can only use the traditional estimation method, so that the actual water content in the grains is inconvenient to determine, and particularly the identification is troublesome when trying to determine whether the grains separated by the threshing machine are suitable for storage. However, the existing grain moisture measuring equipment is almost used by the grain storage department, and the measuring method is that the water content of grains of grain crops can be measured only after the grain crops are sold by farmers and transported to the grain storage department through a plurality of links. However, this measurement method has measurement errors and disadvantages, and the reason for the measurement errors is that the sampling amount of grain is small, the sampling is not uniform when the number of grain to be measured is large, and the time for sending the sampled sample to the measurement chamber is also affected. The existing agricultural threshing mode does not have a method and equipment for measuring the water content, which are economical, fast and suitable for the threshing machine to separate out crop seeds and can carry out large-quantity high-density uniform sampling and high efficiency.
