Description

Technical Field

[0001] The utility model relates to the technical field of dustproof covers for fertilizer boxes, and specifically discloses a rolling curtain type dustproof cover for a fertilizer box of a seed drill. Background Art

[0002] The fertilizer box of the seeder is a device used to store and transport fertilizers during the operation of the seeder. It is usually made of stainless steel and has the characteristics of corrosion resistance, durability and not easy to deform. During the use of the fertilizer box of the seeder, in order to prevent impurities such as dust and fallen leaves from entering the fertilizer box and affecting the quality of fertilizer and fertilization, it is necessary to install a dust cover on the top of the fertilizer box. The existing dust cover of the fertilizer box is mostly made of stainless steel, which is heavy and easily leads to an increase in the overall weight of the fertilizer box, which increases the fuel consumption of the seeder during the sowing process, which is not conducive to cost saving. The existing dust cover of the fertilizer box cannot be folded and takes up space when opened. In addition, the existing dust cover of the fertilizer box can only be used as a dust-proof cover for the fertilizer box and cannot be used as an emergency mat or covering cloth, which limits the utilization rate of the dust cover and easily causes a waste of resources. Therefore, in order to solve the above problems, the utility model proposes a roller curtain type dust cover for the fertilizer box of the seeder. Utility Model Content

[0003] The utility model aims to provide a rolling curtain dust cover for a fertilizer box of a seeder, which reduces the weight of the dust cover, saves fuel consumption of the seeder, is convenient for winding and unwinding, reduces space occupancy, and can separate the dust cloth from a supporting mechanism and use it separately as an emergency mat or covering cloth, thereby improving the utilization rate of the dust cover and saving resources.

[0006] As a further arrangement of the above scheme, a dust plug is provided on the inner side of the connecting groove. The above design can keep the inner wall of the connecting groove clean and tidy, making it convenient for the subsequent connection between the crank and the reel.

[0007] As a further configuration of the above scheme, one side of the connecting plate is connected to the fertilizer box body, and a second reserved hole is provided at one end of the connecting plate close to the limiting plate, and bolts are provided through the inside of the second reserved hole and the first reserved hole at the same time, and a gasket is provided on the outside of the bolt, and a nut is provided on one side of the gasket. The above design facilitates the connection and separation of the limiting plate and the connecting plate, and can fix the reel to one end of the supporting mechanism before the dustproof cloth is rolled up. After unfolding, the limiting plate is connected to the connecting plate on the other side of the fertilizer box body using bolts and nuts to fix the position of the reel and the dustproof cloth, and further limit the position of the reel and the dustproof cloth during the operation of the seeder to ensure the use effect of the dust cover.

[0008] As a further configuration of the above scheme, a plurality of card slots are provided inside the storage box, and a cover is provided on one side of the storage box. The card slots are engaged with the crank handle. The above design can standardize the position of the crank handle to avoid loss of the crank handle and facilitate the opening and closing of the dustproof cloth roll. Beneficial Effects

[0009] During the use of the utility model, the handle drives the reel and the dustproof cloth roll to rotate, so that the dustproof cloth can be unfolded from one side of the fertilizer box body to the other side along the three guide holes to form a dust cover. The split design of the support plate, the transition plate and the sealing plate in the support mechanism makes it easy to separate the dustproof cloth roll from the support mechanism, so that the dustproof cloth roll can be used as an emergency mat or covering cloth. The support mechanism and the limiting mechanism are used in combination to limit the unfolding trajectory of the dustproof cloth roll and the position of the dustproof cloth, so that the dustproof cloth (cover) can be used in actual use. The split design of the crank and the reel makes it easy to connect the crank and the reel during winding and unwinding. After winding and unwinding, the crank and the reel are separated and placed in the storage box. After separation, the dust plug is connected to the connecting grooves at both ends of the reel to prevent dirt, dust and other impurities from entering the connecting grooves during the sowing process of the seeder, affecting the connection between the crank and the reel. The use of multiple buckles in the storage box can effectively standardize the position of the crank and avoid bumping into the crank. BRIEF DESCRIPTION OF THE DRAWINGS
