Description

Technical Field

[0001] The present invention belongs to the technical field of food sampling, and particularly relates to a sampling device for fishery food processing and detection. Background Art

[0002] Fishery, also known as the aquaculture industry, is a social industrial sector in which humans utilize the material transformation function of organisms in water areas to obtain aquatic products through fishing, aquaculture, and processing. In addition to being directly sold in the market, some of the common aquatic organisms in fishery will enter aquatic product factories to be processed into various spherical foods, such as fish balls and shrimp balls.

[0003] When processing such spherical foods, the raw materials need to be broken and then mixed. After being mixed into a colloidal state, they are extruded into spherical shapes through an extrusion molding machine. Usually, sampling and detection are required after mixing to understand the mixing situation. The common sampling method is to insert a round tube into the colloidal raw materials for sampling. However, in this sampling method, the uppermost raw materials are taken away each time of sampling, which will affect the detection accuracy when sampling raw materials at other depths. In view of the above problems, we propose a sampling device for fishery food processing and detection. Summary of the Invention

[0004] The purpose of the present invention is to provide a sampling device for fishery food processing and detection to solve the problems existing in the background art.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0006] A sampling device for fishery food processing and detection includes a sampling tube. The lower end of the sampling tube is closed, and a handle is fixedly connected to the upper end of the sampling tube. A sampling groove is opened in the lower part of the side surface of the sampling tube. A sealing plate matching the sampling groove is connected to the inner wall of the sampling tube through a connecting member. The connecting member includes an intermediate plate. A plurality of first springs fixedly connected to the sealing plate are fixedly connected to the front side of the intermediate plate. A plurality of second springs fixedly connected to the inner wall of the sampling tube are fixedly connected to the rear end of the intermediate plate. A motor is fixedly connected to the inner side of the sampling tube above the connecting member. The output end of the motor is fixedly connected to a runner above the intermediate plate. The side surface of the runner has a convex portion, and when the convex portion faces downward, its lowermost end will be lower than the upper end of the intermediate plate.

[0007] The handle is internally provided with a battery for supplying power to the motor.

[0008] A control switch for controlling the forward or reverse rotation of the motor is provided on the side surface of the handle.

[0009] The sampling tube includes a main tube body and a sample storage tube body detachably connected to the lower end of the main tube body. The sampling groove is opened on the main tube body.

[0010] The lower end of the sample storage tube body is hemispherical.

[0011] The main tube body includes an upper tube body and an intermediate tube body detachably connected to the lower end of the upper tube body. The lower part inside the upper tube body is closed, and the sampling groove is formed on the intermediate tube body.

[0012] A retaining ring matching the sealing plate is fixedly connected to the inner side of the sampling groove.

[0013] A first telescopic sleeve and a second telescopic sleeve are respectively sleeved outside the first spring and the second spring. Two ends of the first telescopic sleeve are fixedly connected to the intermediate plate and the sealing plate respectively, and two ends of the second telescopic sleeve are fixedly connected to the intermediate plate and the intermediate tube body respectively.

[0014] The present invention provides a sampling device for fishery food processing and detection. When sampling, the sampling device can smoothly enter and exit colloidal raw materials. In addition, when sampling raw materials at different depths, accurate sampling can be achieved, and the raw materials in the upper layer will not be taken in at the same time, avoiding the mixing of raw materials at different depths and affecting the detection accuracy. At the same time, when the sampling tube withdraws from the raw materials, the sealing plate can be in close contact with the retaining ring, preventing the sealing plate from being opened by the vacuum effect when the sampling tube is withdrawn.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0022] Embodiment 1

[0023] As Figures 1-3As shown in the figure, a sampling device for fishery food processing and detection according to the present invention includes a sampling tube 1. The lower end of the sampling tube 1 is closed, and a handle 2 is fixedly connected to the upper end of the sampling tube 1. The handle 2 houses a battery that provides power for a motor 27. A control switch 3 for controlling the forward or reverse rotation of the motor 27 is provided on the side of the handle 2. A sampling groove 21 is formed in the lower part of the side of the sampling tube 1. A sealing plate 23 that matches the sampling groove 21 is connected to the inner wall of the sampling tube 1 through a connecting member 22. The connecting member 22 includes an intermediate plate 24. A plurality of first springs 25 fixedly connected to the sealing plate 23 are fixedly connected to the front side of the intermediate plate 24. A plurality of second springs 26 fixedly connected to the inner wall of the sampling tube 1 are fixedly connected to the rear end of the intermediate plate 24. A motor 27 located above the connecting member 22 is fixedly connected to the inside of the sampling tube 1. An output end of the motor 27 is fixedly connected to a runner 28 located above the intermediate plate 24. A convex portion 29 is provided on the side of the runner 28. When the convex portion 29 faces downward, its lowermost end will be lower than the upper end of the intermediate plate 24. A retaining ring 35 that matches the sealing plate 23 is fixedly connected to the inside of the sampling groove 21.

[0024] The second spring 26 will pull the sealing plate 23 towards the inside of the sampling tube 1 through the intermediate plate 24 and the first spring 25 under its own elastic force, so that the sealing plate 23 abuts against the retaining ring 35, thereby closing the sampling groove 21.

[0025] When the control switch 3 is used to control the motor 27 to drive the runner 28 to rotate forward cyclically, the convex portion 29 on the side of the runner 28 will rotate forward together. In this way, the convex portion 29 will contact the intermediate plate 24 from the front side of the intermediate plate 24, and then push the intermediate plate 24 backward until it separates from the intermediate plate 24. This process will push the intermediate plate 24 backward by a certain distance, thereby stretching the first spring 25 and making the sealing plate 23 abut against the retaining ring 35 more tightly. After the convex portion 29 separates from the intermediate plate 24, the first spring 25 will rebound to reset the intermediate plate 24. In addition, when the convex portion 29 makes a circular motion, the center mass point of the runner 28 is not on the rotation center of the motor 27, so that the motor 27 is in a state of continuous imbalance, and the lower part of the sampling tube 1 will vibrate under the action of inertia;

[0026] Simply put, when the runner 28 rotates forward, the sealing plate 23 will abut against the retaining ring 35 more tightly, and at the same time, the lower part of the sampling tube 1 will vibrate.

[0027] When the motor 27 drives the runner 28 to rotate in reverse cyclically by controlling the switch 3, the convex part 29 on the side of the runner 28 will rotate in reverse together. In this way, the convex part 29 will contact the middle plate 24 from the rear side of the middle plate 24, and then push the middle plate 24 forward until it disengages from the middle plate 24. This process will push the middle plate 24 forward by a certain distance. On the one hand, this will stretch the second spring 26, and on the other hand, it will push the sealing plate 23 forward through the first spring 25, so that the sealing plate 23 withdraws from the sampling groove 21, opening the sampling groove 21. After the convex part 29 disengages from the contact with the middle plate 24, the second spring 26 will rebound to reset the middle plate 24 and the sealing plate 23. In addition, when the convex part 29 makes a circular motion, the center mass point of the runner 28 is not on the rotation center of the motor 27, causing the lower part of the sampling tube 1 to vibrate continuously under the action of inertia;

[0028] Simply put, when the runner 28 rotates in reverse, the sampling groove 21 will open, and at the same time, the lower part of the sampling tube 1 will vibrate.

[0029] During sampling, the motor 27 is controlled by the control switch 3 to drive the runner 28 to rotate forward cyclically, and then the sampling tube 1 is inserted into the colloidal raw material. Since the sampling tube 1 is vibrating continuously, when the sampling tube 1 is inserted into the raw material, the surrounding raw material will vibrate together, which will enhance the fluidity of the raw material. Therefore, the sampling tube 1 can be smoothly inserted into the raw material. After the sampling tube 1 is inserted to the target sampling depth, the motor 27 is controlled by the control switch 3 to drive the runner 28 to rotate in reverse cyclically, opening the sampling groove 21. Since the sampling tube 1 and the sealing plate 23 are vibrating continuously at this time, the raw material around the sampling groove 21 will quickly flow into the sampling tube 1. After taking an appropriate amount, the motor 27 is controlled by the switch 3 to drive the runner 28 to rotate forward cyclically to close the sampling groove 21. At this time, the sampling tube 1 can be withdrawn, and the sampling is completed. Subsequently, the control sampling groove 21 can be opened to take out the raw material sample from the sampling tube 1.

[0030] From the above sampling operation, it can be seen that the sampling device can smoothly enter and exit the colloidal raw material during sampling. In addition, it can achieve accurate sampling when sampling raw materials at different depths, and will not take in the upper-layer raw materials at the same time, avoiding the mixing of raw materials at different depths and affecting the detection accuracy. At the same time, when the sampling tube 1 withdraws from the raw material, the sealing plate 23 can be in close contact with the retaining ring 35, preventing the sealing plate 23 from being opened by the vacuum effect when the sampling tube 1 is withdrawn.

[0031] Embodiment 2

[0032] This implementation has made further improvements on the basis of the previous implementation. As shown in the figure, the sampling tube 1 includes a main tube body 31 and a sample storage tube body 32 detachably connected to the lower end of the main tube body 31. A sampling groove 21 is formed in the main tube body 31. The lower end of the sample storage tube body 32 is hemispherical. The main tube body 31 includes an upper tube body 33 and an intermediate tube body 34 detachably connected to the lower end of the upper tube body 33. The lower part inside the upper tube body 33 is closed, and the sampling groove 21 is formed in the intermediate tube body 34.

[0033] Detaching the sample storage tube body 32 alone facilitates taking out the raw material sample inside the sample storage tube body 32 and also facilitates cleaning the sample storage tube body 32. Similarly, dividing the main tube body 31 into the upper tube body 33 and the intermediate tube body 34 is also for the convenience of cleaning. The hemispherical shape of the lower end of the sample storage tube body 32 can reduce the resistance when the sampling tube 1 is inserted into the raw material.

[0034] A first telescopic sleeve 36 and a second telescopic sleeve 37 are respectively sleeved outside the first spring 25 and the second spring 26. The two ends of the first telescopic sleeve 36 are fixedly connected to the intermediate plate 24 and the sealing plate 23 respectively. The two ends of the second telescopic sleeve 37 are fixedly connected to the intermediate plate 24 and the intermediate tube body 34 respectively. The settings of the first telescopic sleeve 36 and the second telescopic sleeve 37 can play a guiding role for the first spring 25 and the second spring 26, preventing them from bending and deforming.

[0035] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
