Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, and more specifically, to a grain threshing and storage device for grain processing. Background Technology
[0002] The term "grains" encompasses a broad range, including rice, wheat, millet, soybeans, and other miscellaneous grains. Grains, including rice, wheat, millet, and soybeans, are primarily plant seeds and fruits. They are a traditional staple food for many Asian people. After harvesting, grains undergo multiple processing steps. Threshing, bran removal, and storage are the most crucial processes in the combined harvesting of grains, with storage devices being essential for this process.
[0003] Currently, after threshing and bran removal, most grains are directly poured into storage devices. At this time, a large number of straws and debris of varying sizes remain in the grains. These impurities may contain insect eggs. If stored together with the grains for a long time, the grains are prone to insect infestation or mold. Moreover, if the grains are too damp, they will also become damp and deteriorate. Therefore, this application proposes a threshing and storage device for grain processing to solve this problem.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] The purpose of this invention is to provide a grain threshing and storage device for grain processing, so as to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model is a threshing and storage device for grain processing. It is equipped with a storage box, a sieve plate, a first motor and a bag filter. The first motor drives the sieve plate to vibrate and filter larger impurities in the grain. When the filtered grain falls, the bag filter extracts smaller impurities from the grain. After sieving is completed, the feed valve is closed and the grain is stored in the storage box, which achieves the effect of filtering and storing grain.
[0015] This utility model is a threshing and storage device for grain processing. It is equipped with a threaded roller assembly, a second motor, a temperature and humidity sensor, a heater, and an air pump. The temperature and humidity sensor detects the temperature and humidity inside the storage silo. When the temperature is detected to be higher than a preset value, the second motor drives the threaded roller assembly to rotate, causing the grain to tumble inside the storage silo. At the same time, the air pump and the feed valve are opened, and the air pump discharges the high-temperature gas from the storage silo. When the humidity is higher than the preset value, the heater can also be turned on to heat the grain inside the storage silo. Combined with the air pump, the grain is dried. It not only has the effect of heat-proof and moisture-proof grain storage, but also has the feature of automatically turning the grain. Attached Figure Description

[0023] Please see Figure 1-3 According to an embodiment of the present invention, a grain threshing and storage device for grain processing includes a storage box 1, a screening bin 2 at the top of the storage box 1, a screening plate 3 inside the screening bin 2, a first motor 4 connected to a rotating shaft on one side of the screening plate 3, a bag filter 5 below one side of the screening bin 2, a storage hopper 7 inside the storage box 1, a feed valve 6 between the screening bin 2 and the storage hopper 7, a temperature and humidity sensor 8 on one side of the storage hopper 7, a heater 9 at the bottom of the storage hopper 7, and a threaded roller inside the storage hopper 7. Group 10, the top shaft of the threaded roller group 10 is connected to a second motor 11, the bottom end of the threaded roller group 10 is provided with a sprocket 12, and a transmission chain 13 is sleeved on one side of the sprocket 12. The top pipe of the storage silo 7 is connected to an air exchange pump 15, and a discharge valve 14 is installed on the lower side of the storage silo 7. This utility model uses the screen plate 3 and the bag dust collector 5 to remove dust from the grain, and uses the threaded roller group 10 and the air exchange pump 15 to automatically turn and dry the grain. It not only has the effect of auxiliary dust removal, but also has the characteristics of automatic turning and moisture prevention.
[0024] According to the above-mentioned scheme of this utility model, the sieve plate 3 is connected to the storage box 1 by a bearing, and the first motor 4 is bolted to the storage box 1. The first motor 4 is composed of a geared motor and is used to drive the sieve plate 3 to shake and filter the grain.
[0025] According to the above-described scheme of this utility model, the bag filter 5 is bolted to the storage box 1, and the feed valve 6 is bolted to the storage box 1 for extracting smaller impurities from the grain.
[0026] According to the above-mentioned scheme of this utility model, the temperature and humidity sensor 8 is bolted to the storage box 1, the heater 9 is bolted to the storage box 1, and the air exchange pump 15 is bolted to the storage box 1 for auxiliary heating, ventilation and moisture prevention.
[0027] According to the above-described scheme of this utility model, the threaded roller assembly 10 is connected to the storage box 1 by a bearing, the second motor 11 is bolted to the storage box 1, the sprocket 12 is bolted to the threaded roller assembly 10, and the second motor 11 is a geared motor used to turn over the grain.
[0028] According to the above-described scheme of this utility model, a control box 16 is fixedly installed on one side of the storage box 1. The control box 16 is electrically connected to the first motor 4, the second motor 11, the bag dust collector 5, the temperature and humidity sensor 8, the heater 9 and the air exchange pump 15 respectively.
