Description

Technical Field

[0001] The utility model relates to the field of equipment for rice production, in particular to a weight mechanism for the discharge port of a rice milling machine. Background Art

[0002] A rice milling machine is a device used to remove the husk and whiten brown rice. It achieves the processing of brown rice through the mechanical force generated by mechanical equipment. The working principle of the rice milling machine is to achieve whitening through the rotation and flipping of rice grains. During the processing, the rice grains undergo a rolling motion, enabling each rice grain to equally receive the effect of the rice milling machine, thereby achieving uniform rice milling. Components such as the whitening roller, rice knife, and round-hole sieve of the rice milling machine play a key role in the processing. They cause the rice grains to roll and collide through different speeds and angles, thereby achieving the effect of husk removal and whitening.

[0003] The weight mechanism at the discharge port of the rice milling machine is an important device used to adjust the discharge flow rate and ensure the smooth operation of the processing equipment. The discharge device of the rice milling machine includes a discharge port, a rotating rod, a baffle plate, a threaded rod, a weight block, and a receiving hopper. The main purpose of this device is to send the rice into the receiving hopper through the discharge port after the rice milling device removes the husk and whitens the rice. When the rice discharging speed is too fast, the rice will splash out of the receiving hopper due to the inertia during the descent. Falling on the ground will not only be soiled by dust but also be extremely troublesome to handle. Therefore, by setting a rotating rod and a baffle plate on one side of the discharge port, the discharging speed of the rice can be effectively controlled, avoiding the splashing of the rice. In addition, by increasing or decreasing or moving the weight block, the adjustment of the discharge flow rate of the rice milling machine can be achieved, which is convenient to use and conducive to the smooth operation of the processing equipment.

[0004] The design of this weight mechanism not only improves the efficiency of the rice milling machine but also reduces the waste of rice. At the same time, it simplifies the subsequent cleaning work and is a practical and effective technical improvement.

[0005] However, there are still some problems with the existing weight mechanism for the discharge port of this rice milling machine. Specifically, when the weight block or the connecting rod of the weight block is corroded, the removal and installation of the weight block will be affected, making it inconvenient to disassemble and assemble. Thus, it is not convenient to adjust the weight, which is not conducive to the control of the discharge volume. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a weight mechanism for the discharge port of a rice milling machine, which solves the problem that the weight block of the existing rice milling machine is inconvenient to install and remove due to corrosion, thus affecting the adjustment of the weight of the baffle plate at the discharge port.

[0007] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A weight balancing mechanism for the discharge port of a rice milling machine, comprising a rotating shaft, a weight rod, and a weight block. The rotating shaft is rotatably connected to the top of the discharge port baffle. The weight rod is perpendicular to the rotating shaft and is arranged on both sides of the rotating shaft. The weight block is fixed in the middle of the weight rod. The weight block is provided with a weight chamber. The top of the weight chamber is provided with a weight material filling inlet, and the bottom of the weight chamber is provided with a weight material discharge outlet.

[0009] The original detachable weight block is changed to a fixed weight block. The weight block is directly fixed in the middle of the weight rod. Then, by filling different densities and amounts of weight materials into the weight chamber of the weight block, precise weight balancing can be achieved. Even if it rusts, it is convenient to adjust the weight. This solves the problem that the weight block of the existing rice milling machine is not easy to install and remove due to rust, making it difficult to adjust the weight of the discharge port baffle.

[0010] As a further preference of the present utility model, there are at least three weight chambers, and the weight chambers are not connected to each other.

[0011] Setting multiple weight chambers is more convenient for selecting the weight position, making the weight balancing more precise.

[0012] As a further preference of the present utility model, the cross-section of the weight chamber is circular.

[0013] It is convenient to discharge the weight material from the weight material discharge outlet.

[0014] As a further preference of the present utility model, a funnel-shaped feeding structure is provided at the weight material filling inlet, and a blanking plug is provided at the top of the funnel-shaped feeding structure.

[0015] In this way, it is not easy to have the problem of material spilling when adding weight materials.

[0016] As a further preference of the present utility model, a lower plug is provided at the weight material discharge outlet, and the lower plug is threadedly connected to the weight chamber.

[0017] It can block the weight material and prevent the weight material from falling out from the weight material discharge outlet when using this weight balancing structure.

[0018] As a further preference of the present utility model, a guide plate is further provided at the bottom of the weight material discharge outlet, and the top of the guide plate is rotatably connected to the weight block through a connecting rod.

[0019] When it is necessary to discharge the weight material, the guide plate can be rotated to a suitable position, so that the falling weight material can be accurately guided to the material receiving mechanism, making it more convenient for the recovery of the weight material.

[0020] Compared with the prior art, the present utility model can achieve at least one of the following beneficial effects:

[0021] 1. The original detachable counterweight block is changed to a fixed counterweight block. The counterweight block is directly fixed in the middle of the counterweight rod, and then by pouring counterweight materials with different densities and different amounts into the counterweight chamber of the counterweight block, precise counterweight can be achieved. Even if it rusts, it is convenient to adjust the counterweight, solving the problem that the counterweight block of the existing rice mill is not easy to install and remove due to rust for adjusting the counterweight of the discharge port baffle.

[0022] 2. Setting multiple counterweight chambers is more convenient for selecting the counterweight position, making the counterweight more accurate.

[0023] 3. In this way, it is not easy to have the problem of material spilling when adding counterweight materials.

[0024] 4. It can block the counterweight materials to prevent the counterweight materials from falling out from the counterweight material discharge port when using this counterweight structure.

[0025] 5. When it is necessary to discharge the counterweight materials, the guide plate can be rotated to a suitable position, so that the falling counterweight materials can be accurately guided to the material receiving mechanism, which is more convenient for the recovery of the counterweight materials.
