Description

Technical Field

[0001] This utility model belongs to the field of grain processing technology, specifically relating to a drying device for grain processing. Background Technology

[0002] Sun-drying is a crucial step in grain processing. Traditional methods often involve laying grains out to dry in the open. However, this method is vulnerable to sudden rainfall. The grains must be manually collected, which is time-consuming and labor-intensive. Furthermore, it's difficult to collect them quickly enough, leading to the grains getting wet, affecting their quality, and increasing the difficulty and cost of subsequent processing. While some drying devices exist on the market, most lack adequate rain protection and collection capabilities, failing to respond quickly and effectively to sudden rainfall and thus failing to meet actual production needs. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a drying device for processing grains, which can quickly collect dried grains during rain, reducing manpower, improving collection efficiency, and preventing grains from being damaged by rain.

[0004] A drying device for processing miscellaneous grains includes a support, a guide rod at the top of the support, a collection hopper mounted on the guide rod, and a drying assembly at the top of the guide rod.

[0005] The drying assembly includes an upper support fixed to the top of a guide rod and a movable support sleeved on the guide rod. A plurality of upper mounting seats are arranged in a ring around the outer periphery of the upper support, and a support rod is movably mounted on each upper mounting seat. A plurality of lower mounting seats are arranged in a ring around the outer periphery of the movable support, and a top rod is movably mounted on each lower mounting seat. The top rod is movably connected to the center of the support rod.

[0006] A pair of geared motors are provided on the upper support, and the output shaft of the geared motors is provided with a lead screw. A pair of threaded holes are provided on the movable support, and the lead screw is screwed into the threaded holes of the movable support. A drying cloth is provided on several of the support rods.

[0007] When rain is detected, the geared motor is activated via an external control switch to rotate forward. The geared motor drives the lead screw to rotate, and because the lead screw engages with the threaded hole of the movable support, the movable support moves downward along the guide rod. As the movable support moves downward, the top rod pushes the support rod to rotate around the upper mounting base, causing several support rods to converge towards the center, thereby quickly retracting the drying cloth and collecting the grains on the cloth into the collection hopper for rapid collection.

[0008] Further technical solutions:

[0009] The base is equipped with multiple casters, each with a brake. This allows the device to be easily moved to a suitable location for drying, and can be quickly moved to a sheltered place during rain. The brakes also ensure the stability of the device during use.

[0010] The collecting hopper has a funnel-shaped structure, and the inner wall of the collecting hopper is provided with a smooth, non-stick coating. The funnel-shaped structure facilitates the concentrated sliding and collection of grains, while the smooth, non-stick coating prevents grains from sticking to the inner wall of the collecting hopper, making collection and cleaning easier.

[0011] The lower mounting base and the top rod are connected by a movable pin, and limit plates are provided at both ends of the movable pin. This connection method allows the top rod to move flexibly, and the limit plates prevent the movable pin from falling off, ensuring the normal operation of the device.

[0012] The drying cloth is made of breathable and corrosion-resistant nylon, and its edges are reinforced. The breathable nylon material facilitates ventilation during grain drying, the corrosion resistance extends the service life of the drying cloth, and the reinforced edges enhance its strength and prevent damage during unfolding and drying.

[0013] The geared motor is a reversible motor and is electrically connected to an external control switch. The control switch has three control positions: forward, reverse, and stop. The reversible geared motor facilitates the unfolding and retraction of the drying cloth, and the three positions of the control switch allow the operator to operate flexibly according to the actual situation.

[0014] The lead screw and the threaded hole of the movable support are fitted with grease, and a limit block is provided at the bottom end of the lead screw. The grease can reduce the friction between the lead screw and the threaded hole, extending the service life of the device, and the limit block can prevent the movable support from moving excessively downward.

[0015] The center point of the unfolded drying cloth is on the same vertical axis as the center of the collecting hopper, and the area of ​​the drying cloth is smaller than the area of ​​the top opening of the collecting hopper. This ensures that the grains fall accurately into the collecting hopper during collection, preventing spillage.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a drying and folding assembly. By using a geared motor to drive a lead screw to rotate, the movable support moves up and down, enabling the drying cloth to be quickly folded and unfolded. In case of rain, the dried grains can be quickly collected into the collection hopper, greatly improving rainproof collection efficiency, reducing manual operation, lowering the risk of damage to the grains due to rain, and ensuring the quality of the grains.
