Description

Technical Field

[0001] This utility model relates to the field of yellow mealworm processing technology, and in particular to a novel yellow mealworm grinding device. Background Technology

[0002] Yellow mealworms are rich in various nutrients and are an important insect resource, widely used in food, health products, medicine, and feed. In practical applications, dried yellow mealworms are usually ground into powder or granules for further processing.

[0003] Existing mealworm grinding devices, such as the one disclosed in patent CN215694674U, use a first motor and crushing blades to perform initial crushing of the mealworms. A second motor, a fixed grinding disc, and a rotating grinding disc then perform further grinding of the crushed mealworms. While this secondary grinding increases the crushing rate, different products require different particle sizes for the mealworm powder; finer powder is not always better. This device cannot control or adjust the particle size of the crushed mealworms, or effectively screen the powder, thus lacking practicality and requiring improvement. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a novel mealworm grinding device, including a frame, a screen cylinder, a crushing roller, a drive motor, and a transmission assembly. The screen cylinder is fixedly mounted on the frame on both sides by connecting plates. The crushing roller is axially rotatable inside the screen cylinder with its main shaft extending out of the screen cylinder at one end. The drive motor is mounted on the frame and located on one side of the screen cylinder. The drive motor is connected to the main shaft of the crushing roller via the transmission assembly. The top of the screen cylinder is provided with a feeding hopper, and the bottom of the screen cylinder is provided with a detachable screen plate with several screen holes.

[0005] Furthermore, the bottom of the screen cylinder is provided with recessed insertion grooves on both sides of the screen plate, and the screen plate is provided with protruding insertion strips on both sides, the insertion strips being movably disposed in the insertion grooves.

[0006] Furthermore, a handle is provided at one end of the sieve plate.

[0007] Furthermore, the crushing roller is provided with multiple sets of crushing blades in the circumferential direction.

[0008] Furthermore, the bottom of the sieve plate is inclined and equipped with a receiving hopper.

[0009] Furthermore, the transmission assembly includes a first pulley, a second pulley, and a belt. The first pulley is connected to the drive motor, the second pulley is connected to the main shaft of the crushing roller, and the belt is connected to the first pulley and the second pulley.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] This invention uses a drive motor to rotate a crushing roller at high speed to crush mealworms inside a sieve cylinder. The crushed mealworm powder is discharged through a sieve plate. By changing the sieve plate with different apertures, different particle sizes of mealworm powder can be screened, thereby meeting the needs of different products and improving the practicality of the grinding device.
