Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, in particular to a storage box discharging mechanism. Background Art

[0002] Grain storage boxes are mainly used for storing grains and cereals to prevent moisture, pests, etc. The storage box is generally a box structure. When grain is needed, the discharge device installed in the storage box is activated to release it in an orderly manner. The existing discharge device is installed at the bottom of the storage box and is blocked by a baffle. The baffle can be flipped or retracted to release or block by partition, but it is easy to get stuck, especially for large grains. Large grains are easy to squeeze each other, making it difficult for the baffle to align with the slot for partitioning.

[0003] Therefore, the utility model improves the characteristics of the existing storage box discharge mechanism, and avoids the problem that the discharge port is difficult to block due to squeezing due to large grain particles when the discharge port is blocked. Utility Model Content

[0004] The utility model aims to provide a storage box discharge mechanism, which is improved according to the characteristics of the existing storage box discharge mechanism and avoids the problem that the discharge port is difficult to block due to squeezing of large grain particles when the discharge port is blocked.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A storage box discharge mechanism comprises a box body, the bottom of the box body is a conical structure, a discharge pipe is connected to the corresponding conical bottom of the box body, the discharge pipe has a cylindrical cavity, a discharge tray is installed in the cavity, the discharge tray is composed of a rotating shaft and a baffle fixed to the rotating shaft, the rotating shaft and the cavity are coaxially arranged, the inner side of the baffle is fixed to the side wall of the rotating shaft and is evenly arranged around the rotating shaft, the outer side of the baffle is close to the arc-shaped side wall of the cavity, and the two ends of the rotating shaft are rotatably matched with the front and rear side walls corresponding to the cavity.

[0007] Furthermore, the inner pipeline of the discharge pipe is tangentially connected to the cavity, and the corresponding bottom of the discharge pipe has an arc-shaped discharge port.

[0008] Furthermore, a limit wheel is installed on the outside of the discharge pipe corresponding to the rotating shaft, and the limit wheel is composed of a plurality of limit rods and an outer ring. The inner end of the limit rod is fixed to the rotating shaft and cooperates with the gear rod to limit the position, and the outer end is fixed to the outer ring. The gear rod is installed on the discharge pipe, and the discharge pipe is provided with a rod sleeve for the gear rod, and the gear rod is telescopically matched in the rod sleeve.

[0009] Furthermore, a support frame is installed at the bottom of the box body for raising the box body.

[0010] The utility model has the following beneficial effects: the storage box is placed vertically, and the bottom is conical, which is convenient for concentrated discharge of grains. The cavity is arranged on the discharge pipe, and has a discharge tray. The grains drive the discharge tray to rotate under the action of their own gravity, so as to achieve the purpose of discharge. When it is necessary to block the discharge, as long as the limit shaft rotates, the discharge tray stops rotating, and the mouth of the discharge pipe is blocked by the baffle, the discharge can be prevented immediately, avoiding the obstruction problem caused by the extrusion of large grain particles due to the telescopic blocking.

The storage box is placed vertically with a conical bottom to facilitate concentrated grain discharge. The cavity is arranged on a discharge pipe and has a discharge tray. The grain drives the discharge tray to rotate under its own gravity, thereby achieving the purpose of discharge. When the discharge needs to be blocked, as long as the limit shaft rotates, the discharge tray stops rotating, and the discharge pipe opening is blocked by the baffle, the discharge can be prevented immediately, avoiding the obstruction problem caused by extrusion due to large grain particles in the telescopic blocking.

It is convenient to make the single-side baffle corresponding to the discharge plate bear force. Under the action of the gravity of the grain, the discharge plate rotates to discharge the grain, and the arc-shaped discharge port helps to receive the discharge.

The inner end of the limit rod 41 is fixed to the rotating shaft 31 and cooperates with the gear rod 23 to limit the position, and the outer end is fixed to the outer ring 42. The outer ring is convenient for holding and fixing, and the limit rod cooperates with the gear rod to stop the rotation of the limit wheel and stop the discharge. The gear rod 23 is installed on the discharge tube 2, and the discharge tube 2 is provided with a rod sleeve 22 that is sleeved with the gear rod 23, and the gear rod 23 is telescopically matched in the rod sleeve 22. When the discharge tray needs to be stopped, the gear rod is pushed and extended to the limit wheel to cooperate with the rotation of the limit rod.
