Description

Technical Field

[0001] The invention belongs to the technical field of food detection, in particular to a rapid sample preparation device for food inspection. Background Art

[0002] Food sample preparation technology is a very important part of food quality control. Uneven sample preparation will lead to inaccurate analysis results. Since the number of samples obtained by general methods is large, the particles are too large, and the composition of each part of the food is uneven, in order to ensure the accuracy of the analysis results, the samples need to be crushed and prepared before sample inspection.

[0003] After food sampling is completed, the inspector needs to lift the grinder by hand and pour the sample into a storage container. This process easily causes the sample to spill, while increasing the labor intensity of the inspector and reducing the inspection efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a rapid sample preparation device for food inspection in order to solve the above-mentioned problem that a grinder needs to be lifted by hand and dumped to collect samples.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A rapid sample preparation device for food inspection, comprising a crushing cylinder, a hinge seat is welded at one end of the lower surface of the crushing cylinder, a hinge rod is hinged at the bottom of the hinge seat, a fixed base plate is fixedly installed at one end of the hinge rod away from the hinge seat, a support foot is fixedly installed on the lower surface of the fixed base plate, a threaded hole is opened in the middle of one end of the fixed base plate, and an adjusting threaded rod is threadedly connected inside the threaded hole, and the top of the adjusting threaded rod is rotatably connected to the support rod, a discharge port is provided at one end of the bottom of the crushing cylinder, and a valve is provided at the top of the discharge port, a motor is fixedly installed in the middle of the lower surface of the crushing cylinder, a drive end of the motor passes through the lower surface of the crushing cylinder and is welded with a cutter head, an upper cover is hinged at one end of the top of the crushing cylinder, a threaded hole is opened on the upper surface of the upper cover, and a threaded rod is threadedly connected inside the threaded hole, a brush seat is welded at the bottom of the threaded rod, an annular brush is provided on the outside of the brush seat, a rotating seat is welded in the middle of the lower surface of the brush seat, and a pressing plate is rotatably connected to the bottom of the rotating seat.

[0007] By adopting the above technical scheme, the support rod is moved up and down by rotating the adjusting threaded rod, so as to adjust the angle of the grinding barrel, so that the sample inside the grinding barrel flows out through the discharge port under the action of gravity, so that the inspector does not need to lift the device for manual dumping, thereby improving the convenience of using the device, and the threaded rod drives the pressure plate to move downward, so as to squeeze the food placed inside the grinding barrel, and try to avoid the food jumping inside the grinding barrel under the action of the rotation of the cutter head, which reduces the grinding effect of the cutter head on the food, so that the device has a better grinding effect on the food, and the threaded rod drives the annular brush to move up and down in the vertical direction and rotate in the horizontal direction, so as to clean the inner wall of the grinding barrel, so that the inspector can clean the device more conveniently, thereby improving the convenience of using the device.

[0008] In a preferred embodiment, a rotating block is welded to the upper surface of the threaded rod, and a handle is rotatably connected to one end of the upper surface of the rotating block.

[0009] By adopting the above technical solution, the threaded rod is driven to rotate by the rotating block by holding the handle to perform circular motion, so that the rotation of the threaded rod is more convenient and the convenience of using the device is improved.

[0010] In a preferred embodiment, the outside of the handle is provided with anti-slip grooves.

[0011] By adopting the above technical solution and providing anti-slip grooves, the inspector can hold the handle more stably.

[0012] In a preferred embodiment, the pressing plate is provided with ventilation holes, and there are four ventilation holes in total, and the ventilation holes are distributed in a ring shape along the axis of the pressing plate.

[0013] By adopting the above technical solution, the air above and below the pressing plate can circulate through the vents during the pressing process, thus avoiding the problem of difficulty in pressing down due to upper and lower air pressure caused by squeezing the air during the pressing process, thereby improving the stability of the device.

[0014] In a preferred embodiment, there are two hinged seats, and the hinged seats are symmetrically distributed.

[0015] By adopting the above technical solution and arranging two hinged seats, the support of the hinged seat to the pulverizing cylinder is made more stable, thereby improving the stability of the device.

[0019] By adopting the above technical solution, the annular brush and the grinding cylinder can be fitted more closely, thereby improving the cleaning effect of the annular brush on the inner wall of the grinding cylinder.

[0020] In a preferred embodiment, the pressing plate is a stainless steel pressing plate.

[0021] By adopting the above technical solution, the stainless steel material has excellent corrosion resistance, so that the pressing plate is not easily corroded when pressing food with high moisture content, thereby increasing the service life of the pressing plate.

[0022] In a preferred embodiment, a hole is formed on the fixed base plate, and a sliding rod is slidably connected inside the hole, and the top of the sliding rod is welded to the support rod.

[0023] By adopting the above technical solution, the horizontal range of motion of the support rod is limited by the sliding of the slide rod inside the hole, so as to avoid the support rod from rotating with the rotation of the adjustment threaded rod as much as possible, thereby improving the stability of the support rod.

[0024] In a preferred embodiment, there are two sliding rods, and the sliding rods are symmetrically distributed.

[0025] By adopting the above technical solution and arranging two sliding rods, the restriction of the sliding rod on the supporting rod is made more stable, thereby improving the stability of the supporting rod.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, the support rod is moved up and down by rotating the adjusting threaded rod, so as to adjust the angle of the crushing cylinder, so that the sample inside the crushing cylinder flows out through the discharge port under the action of gravity, so that the inspector does not need to lift the device for manual dumping, thereby improving the convenience of using the device.

[0028] 2. In the present invention, the threaded rod drives the pressing plate to move downward, thereby squeezing the food placed inside the grinding cylinder, and trying to avoid the food jumping inside the grinding cylinder under the action of the rotation of the cutter head, thereby reducing the grinding effect of the cutter head on the food, so that the device has a better grinding effect on the food.

[0029] 3. In the present invention, the threaded rod drives the annular brush to move up and down in the vertical direction and rotate in the horizontal direction, so as to clean the inner wall of the crushing cylinder, making it more convenient for the inspector to clean the device and improving the convenience of using the device.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The following will be combined Figure 1-Figure 3 A rapid sample preparation device for food inspection according to an embodiment of the present invention is described in detail.

[0036] Example:

[0037] Reference Figure 1 and Figure 2 A rapid sample preparation device for food inspection includes a crushing cylinder 1, a motor 9 is fixedly installed in the middle of the lower surface of the crushing cylinder 1, a transmission end of the motor 9 passes through the lower surface of the crushing cylinder 1 and is welded with a cutter head 10. After the food to be sampled is placed in the crushing cylinder 1, the motor 9 is started to drive the cutter head 10 to rotate, so as to cut and crush the food for sample preparation.

[0038] Reference Figure 1 and Figure 2 An upper cover 13 is hinged at one end of the top of the pulverizing cylinder 1, and the upper surface of the pulverizing cylinder 1 is covered and opened by rotating the upper cover 13 at the top of the pulverizing cylinder 1.

[0039] Reference Figure 1 and Figure 2 A threaded hole is formed on the upper surface of the upper cover 13, and a threaded rod 14 is threadedly connected inside the threaded hole. The threaded rod 14 is moved up and down in the vertical direction by rotating inside the threaded hole.

[0040] Reference Figure 1 and Figure 2 A rotating block 15 is welded on the upper surface of the threaded rod 14, and one end of the upper surface of the rotating block 15 is rotatably connected to a handle 16. The threaded rod 14 is driven to rotate through the rotating block 15 by holding the handle 16 for circular motion, making the rotation of the threaded rod 14 more convenient and improving the convenience of using the device.

[0041] Reference Figure 1 and Figure 2 The outside of the handle 16 is provided with anti-skid grooves, which enable the inspector to hold the handle 16 more stably.

[0042] Reference Figure 2 and Figure 3 A brush seat 17 is welded at the bottom of the threaded rod 14, and an annular brush 18 is arranged outside the brush seat 17. The annular brush 18 is installed through the brush seat 17. The threaded rod 14 moves up and down in the vertical direction and rotates in the horizontal direction, driving the annular brush 18 to move up and down in the vertical direction and rotate in the horizontal direction, thereby cleaning the inner wall of the crushing cylinder 1, making it more convenient for the inspector to clean the device.

[0043] Reference Figure 2 and Figure 3 The outer diameter of the annular brush 18 is equal to the inner diameter of the grinding cylinder 1 , so that the annular brush 18 and the grinding cylinder 1 fit more closely, thereby improving the cleaning effect of the annular brush 18 on the inner wall of the grinding cylinder 1 .

[0044] Reference Figure 2 and Figure 3 A rotating seat 19 is welded to the middle of the lower surface of the brush seat 17, and a pressing plate 20 is rotatably connected to the bottom of the rotating seat 19. The brush seat 17 moves up and down in the vertical direction, and the pressing plate 20 is driven to move up and down in the vertical direction through the rotating seat 19, so as to squeeze the food placed in the grinding cylinder 1, and try to avoid the food jumping inside the grinding cylinder 1 under the action of the rotation of the cutter head 10, which reduces the grinding effect of the cutter head 10 on the food, so that the device has a better grinding effect on the food.

[0045] Reference Figure 2 and Figure 3 The pressing plate 20 is a stainless steel pressing plate. The stainless steel material has excellent corrosion resistance, so the pressing plate 20 is not easily corroded when pressing food with more water, thereby increasing the service life of the pressing plate 20.

[0046] Reference Figure 2 and Figure 3The pressing plate 20 is penetrated with ventilation holes 21, and there are four ventilation holes 21 in total. The ventilation holes 21 are distributed in a ring along the axis of the pressing plate 20. By opening the ventilation holes 21, the air above and below the pressing plate 20 can circulate through the ventilation holes 21 during the pressing process of the pressing plate 20, so as to avoid the problem of difficulty in pressing down due to upper and lower air pressure caused by squeezing air during the pressing process of the pressing plate 20, thereby improving the stability of the device.

[0047] Reference Figure 1 and Figure 2 A hinge seat 2 is welded at one end of the lower surface of the grinding cylinder 1, a hinge rod 3 is hinged at the bottom of the hinge seat 2, and a fixed base plate 4 is fixedly installed at one end of the hinge rod 3 away from the hinge seat 2. The angle between the hinge rod 3 and the hinge seat 2 is changed so that the grinding cylinder 1 can present a certain inclination angle with the horizontal plane.

[0048] Reference Figure 1 and Figure 2 There are two articulated seats 2, which are symmetrically distributed. By setting two articulated seats 2, the support of the articulated seats 2 to the crushing cylinder 1 is more stable, thereby improving the stability of the device.

[0049] Reference Figure 1 and Figure 2 The lower surface of the fixed base plate 4 is fixedly mounted with supporting feet 5 , and there are four supporting feet 5 in total. The supporting feet 5 are distributed in a rectangular array around the lower surface of the fixed base plate 4 , and the fixed base plate 4 is supported and fixed by the supporting feet 5 .

[0050] Reference Figure 1 and Figure 2 A threaded hole is provided in the middle of one end of the fixed base plate 4, and an adjusting threaded rod 6 is threadedly connected inside the threaded hole, and a support rod 7 is rotatably connected to the top of the adjusting threaded rod 6, and the top of the support rod 7 abuts against the lower surface of the crushing tube 1. The adjusting threaded rod 6 is rotated inside the threaded hole to move up and down in the vertical direction, driving the support rod 7 to move up and down, thereby changing the angle between the crushing tube 1 and the horizontal plane.

[0051] Reference Figure 1 and Figure 2 A hole is provided on the fixed base plate 4, and a slide rod 8 is slidably connected inside the hole. The top of the slide rod 8 is welded to the support rod 7. The sliding range of the support rod 7 in the horizontal direction is limited by the sliding of the slide rod 8 inside the hole, and the support rod 7 is prevented from rotating with the rotation of the adjusting threaded rod 6 as much as possible, thereby improving the stability of the support rod 7.

[0052] Reference Figure 1 and Figure 2 There are two slide bars 8 in total, and the slide bars 8 are symmetrically distributed. By setting two slide bars 8, the restriction of the slide bars 8 on the support bars 7 is more stable, thereby improving the stability of the support bars 7.

[0053] Reference Figure 1 and Figure 2 A discharge port 11 is provided at one end of the bottom of the grinding cylinder 1, and a valve 12 is provided on the top of the discharge port 11. After the food is crushed and sampled, the threaded rod 6 is rotated to adjust the support rod 7 to move downward, so that the grinding cylinder 1 forms a certain angle with the horizontal plane. After the valve 12 is opened, the sample inside the grinding cylinder 1 flows out through the discharge port 11 under the action of gravity, and the tester can collect the sample by placing the collection container under the discharge port 11.

[0054] The implementation principle of a rapid sample preparation device for food inspection of the present invention is as follows:

[0055] Start the motor 9 to drive the cutter head 10 to rotate, cut and crush the food for sampling. After the food is crushed and sampled, rotate the adjusting threaded rod 6 to drive the support rod 7 to move downward, so that the grinding cylinder 1 forms a certain angle with the horizontal plane. After opening the valve 12, the sample inside the grinding cylinder 1 flows out through the discharge port 11 under the action of gravity. The tester can place the collection container under the discharge port 11 to collect the sample.
