A food detection quantitative sampling device disclosed in Chinese patent CN212432610U extends two left and right electric push rods and pushes the fixed plates at the corresponding positions to move the clamped sampling beaker inward to fix it. The servo motor drives the first rotating shaft on the left to drive the gear at the corresponding position to rotate. The right gear drives the first rotating shaft at the corresponding position to rotate under the action of the rotational force of the left gear, thereby causing the two left and right first rotating shafts to drive the crushing wheels at the corresponding positions to rotate inward to crush the sample into particles. However, this device fails to promote the shedding of food materials attached to the surfaces of the food discharge end and the weighing end, which affects the accurate weighing and discharge of food, increases the subsequent processing steps for the attached food materials, and reduces the use efficiency of the device.

[0010] Beneficial Effects

[0011] The utility model provides a quantitative food weighing and detection device. Compared with the prior art, it has the following beneficial effects:

[0012] (1) The quantitative food weighing and detection device is provided with a discharge piece in the device. After the food material on the upper end of the weighing plate is weighed, the second motor is operated through the gear rack assembly. The gear rack assembly drives the push plate, the traction frame, and the discharge plate to move to the left through the telescopic plate. The push plate pushes the food material on the upper end of the weighing plate to move to the left. The discharge plate is separated from the discharge trough on the left side of the shell. The food material gradually falls from the weighing plate, the discharge trough, and the discharge shell into the recovery box, thereby realizing the recovery of the quantitative food. During the above process, the air pump draws in external gas and injects it into the jet block in the push plate through the three-way valve, the branch pipe, and the bellows. The jet block sprays gas to blow on the upper surface of the weighing plate and the right side of the discharge plate, thereby reducing the adhesion of food on the surfaces of the two. This arrangement facilitates the rapid discharge of the quantitative food after weighing is completed, and reduces the adsorption of residual food on the surface of the discharge end, thereby realizing accurate control of the food material output amount and improving the quantitative weighing effect of the device.

[0013] (2) The quantitative food weighing and detection device is provided with a three-way valve in the device. Before the food material is weighed, the three-way valve is reversed and the air pump is started. The gas pumped by the air pump is ejected through the conduit, the three-way valve, the vent pipe, the vent groove, and the jet ring. When the food material is weighed and discharged, the gas blows against the bottom of the stirring rod to promote the material to fall off. At the same time, part of the gas flows to the upper side of the baffle to provide a buffer for the material. This arrangement prevents the bottom of the stirring rod from being blocked and provides a buffer for the falling material, thereby reducing the impact of the material on the weighing plate.
