A crushing shaft motor is mounted at the top of the main power motor, and a crushing shaft is fixedly installed on the output shaft of the crushing shaft motor. A transmission belt is sleeved between the output shaft and the transmission belt. This invention reduces external contact with food materials and minimizes contamination through its trumpet-shaped shape and enclosed design. The transmission belt is driven by the main power shaft at the front end of the main power motor and the auxiliary power motor within the motor protection box. While this patent increases the practicality of the device to some extent, seasonings may become damp and clump together, requiring manual crushing with tools, making the screening operation time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a seasoning screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seasoning screening device, comprising a screening box for seasoning screening, an auxiliary component installed inside the screening box, a processing box with a sealing cover installed at the top of the screening box, an active shaft installed inside the processing box, a drive motor for powering the active shaft installed on the side of the processing box, and multiple crushing rods for breaking up agglomerated seasonings installed on the outer periphery of the active shaft, a limit box installed on the side of the processing box, a two-section lead screw installed inside the limit box, a servo motor for powering the lead screw installed on the side of the limit box, two adjusting blocks installed on the outer periphery of the lead screw, and a baffle installed at one end of the adjusting block inside the processing box, a drive shaft installed inside the processing box, a stepper motor for powering the drive shaft installed at one end of the processing box, and multiple material feeding plates installed on the outer periphery of the drive shaft.

[0006] Specifically, the auxiliary components include two mounting frames installed inside the screening box and a mounting box installed on the side of the screening box.

[0007] Specifically, a filter screen is installed on the inclined surface of the mounting frame, and a vibration motor is installed at the bottom of the mounting frame.

[0008] Specifically, the side of the screening box is connected to two detachable collection boxes, and the inner bottom wall of the screening box is slidably connected to a collection hopper.

[0009] Specifically, an exhaust fan is embedded in the side of the mounting box, a dustproof net is installed inside the mounting box, and a fixed end of an electric push rod is installed at the top of the mounting box.

[0010] Specifically, the drive end of the electric push rod is connected to a cleaning brush through the mounting box, and the top of the mounting box is connected to an exhaust pipe, with one end of the exhaust pipe located inside the screening box connected to an air inlet hood.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] This seasoning screening device, thanks to the design of its drive motor and auxiliary components, features a drive shaft inside the processing box that works in conjunction with multiple sets of crushing rods. Driven by the drive motor, it mechanically crushes clumps of seasonings, preventing them from clogging the screening channel or affecting screening accuracy. It is especially suitable for powdered seasonings that are prone to clumping when damp, eliminating the need for manual pretreatment and reducing labor intensity. Furthermore, a servo motor drives two baffles to move to both sides, causing the crushed seasonings to fall onto a feeding plate. By starting a stepper motor to rotate the feeding plate, the device can achieve uniform feeding. Compared to the processing methods of existing devices, this device can automatically process clumps of seasonings, greatly improving the screening efficiency of the device.

[0013] The auxiliary component's screening box features a tilted double-layer filter screen (fixed by a mounting frame) that enables two-stage screening. This allows for the separation of products of different specifications based on the size of the seasoning particles. A vibration motor drives the filter screen to vibrate, accelerating screening efficiency and reducing material residue. An exhaust fan inside the box extracts dust from the screening box via an exhaust pipe and air inlet hood. A dustproof net prevents dust from entering the exhaust fan and causing damage, while also reducing dust spillage, improving the operating environment, and protecting the health of operators. An electric push rod drives a cleaning brush to move along the filter screen surface, periodically cleaning any adhering material and preventing mesh blockage. This eliminates the need for manual disassembly and cleaning, greatly increasing the device's practicality.

[0014] This seasoning screening device can automatically process clumped seasonings, making the screening operation more time-saving and labor-saving. Attached Figure Description

[0030] Working principle

[0031] The seasoning screening device works as follows: Open the sealed cover of the processing box 2, pour the seasonings to be screened into the processing box 2, close the sealed cover to prevent material splashing or dust overflow during the crushing process, start the drive motor 3, which drives the drive shaft 9 to rotate. Multiple sets of crushing rods 10 around the drive shaft 9 rotate synchronously, mechanically impacting and crushing the clumps of seasonings in the processing box 2 into dispersed particles, preparing for subsequent screening. Based on the seasoning batch and screening requirements, start the servo motor 8, which drives the two-stage lead screw 13 in the limit box 5 to rotate. The lead screw 13 drives two adjusting blocks 14 to move in opposite directions, thereby moving two baffles 6 inside the processing box 2 to precisely adjust the opening of the feed inlet from the bottom of the processing box 2 to the screening box 1. Start the stepper motor 7, which drives the transmission shaft 11 to rotate. Multiple material guide plates 12 around the transmission shaft 11 rotate. The crushed and dispersed seasonings are evenly fed into the feed inlet, allowing them to fall smoothly and evenly onto the filter screen 49 inside the screening box 1. The vibration motor 50 at the bottom of the mounting frame 48 is started, causing the inclined double-layer filter screen 49 to vibrate. Under the action of gravity and vibration, the seasonings slide down the filter screen 49. During the screening process, the exhaust fan 46 on the side of the mounting box 43 is started. The exhaust fan 46 extracts the dust in the screening box 1 through the exhaust pipe 42 and the air inlet hood. The dust is the fine dust generated during the screening process. The dust enters the mounting box 43 through the air inlet hood and exhaust pipe 42 and is intercepted and filtered by the dustproof net 45 on the inner side of the mounting box 43. Clean air is discharged to prevent dust from overflowing and polluting the environment. During the screening process, the electric push rod 44 is started. The drive end of the electric push rod 44 drives the cleaning brush 47 to move along the surface of the filter screen 49 to scrape off the residual material adhering to the filter screen 49.
