Abstract
Description
Technical Field
[0001] This utility model relates to the field of food inspection technology, specifically to a food inspection sample stirring and digestion device that facilitates sample discharge. Background Technology
[0002] Food inspection is a discipline used to assess food quality. Under the guidance of national standards, various types, shapes, and properties of food are inspected according to standards. This type of experiment can be applied to raw materials, semi-finished products, or finished products. The final results are obtained through analysis and processing using various instruments and human senses.
[0003] To facilitate sample preparation, the raw materials need to be placed inside the device for stirring and digestion. Only after the sample solution is prepared can operations such as coating, inoculation, or splashing indicator solution be performed. However, the previous stirring device only had a rotating shaft to prepare the sample. When pouring, it had to be manually leveled, which was difficult to keep stable. The internal liquid would also splash onto the table, causing contamination.
[0004] Now, a novel food testing sample mixing and digestion device that facilitates sample discharge is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a food testing sample stirring and digestion device that facilitates sample discharge, thereby solving the problem of inconvenient pouring mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a food testing sample stirring and digestion device for easy discharge, comprising a base plate and a stirring tank. The stirring tank is disposed on the right side of the top of the base plate, and a base is disposed below the base plate. A slot is provided on the right side of the interior of the base plate. A bracket is installed between the front and rear of the center of the top of the base plate. Fixing blocks are welded to the front and rear ends of the top of the base plate. A handle is installed between the fixing blocks and the bracket. Screw holes are provided on the front and rear ends of the left side of the top of the base plate. Threaded sleeves are fixed to the left sides of the front and rear ends of the base plate, and bolts are assembled between the threaded sleeves and the screw holes.
[0007] As a further technical solution of this utility model, the handle can rotate the fixing block and the base plate in the bracket, and the fixing block is movably connected to the front end and the rear end inside the bracket.
[0008] As a further technical solution of this utility model, the bolt can rotate up and down between the threaded sleeve and the threaded hole, and the bolt, the threaded sleeve and the threaded hole are in the same vertical plane.
[0009] As a further technical solution of this utility model, a bushing is installed between the bottom of the mixing tank and the base plate, a cover plate is snapped onto the top of the mixing tank, and a sealing groove is fixed around the bottom of the cover plate. A second motor is installed at the center of the top of the cover plate, and a rotating rod is movably connected to the center of the bottom of the cover plate. A pressure rod is horizontally arranged above the cover plate, and a first motor is fixed to the right side of the top of the pressure rod. Sleeve blocks are fixed to the right side of the bottom of the pressure rod and the left side of the top of the cover plate, and a rotating block is fixed between the sleeve blocks. An upper sleeve is fixed to the left side of the rotating block, and a lower sleeve is fixed to the lower left corner of the outside of the mixing tank. An insert rod is movably inserted between the upper sleeve and the lower sleeve.
[0010] As a further technical solution of this utility model, the output end of the first motor passes through the sleeve block and is fixedly connected to the rotating block, and the output end of the second motor is fixedly connected to the rotating rod.
[0011] As a further technical solution of this utility model, the upper sleeve and the lower sleeve are on the same vertical plane, and the upper sleeve, the insertion rod and the lower sleeve are inserted together in concentric circles.
[0012] As a further technical solution of this utility model, a vertical rod is welded to the left side of the top of the substrate, and a lead screw is movably connected between the upper and lower sides of the right side of the vertical rod. The outside of the lead screw is fixedly connected to the pressure rod, and a threaded cylinder is installed on the left side inside the pressure rod. A limit groove is longitudinally provided on the surface of the right side of the vertical rod.
[0013] As a further technical solution of this utility model, the left side of the pressure rod is embedded in the limiting groove, and the lead screw is embedded in the threaded cylinder.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the food testing sample stirring and digestion device that facilitates sample pouring not only makes it easy to pour the sample liquid and achieves rapid sample preparation, but also avoids sample liquid splashing.
[0015] (1) By setting a base under the substrate, screw out the bolts at the threaded sleeves at both ends, hold the handle at the front end, and then rotate the fixing block on the substrate at the bracket above the base until the mixing mechanism on the right side of the substrate is in a left-high-right-low posture and guides the liquid out at the slot. After finishing, reset the substrate and other items and screw the bolts into the screw holes for fixing. No manual support is required, saving effort and time.
[0016] (2) By attaching a cover plate to the top of the mixing tank and resetting the cover plate with a pressure rod, the upper sleeve also approaches the lower sleeve along the insertion rod. The motor can be started to crush the solid food sample in the mixing tank, speed up the mixing speed, and cooperate with the rotation of the motor to transmit power to the cover plate through the rotating block. Since the cover plate is attached to the top of the mixing tank through the sealing groove, the mixing tank is synchronously driven to rotate above the bushing under the connection of the upper sleeve, the insertion rod and the lower sleeve, thus speeding up the dissolution speed.
[0017] (3) By installing a threaded cylinder on the left side inside the pressure rod, the movement of the pressure rod is determined by the screw on the left side. By simply holding the top of the screw, the pressure rod with the threaded cylinder can be raised and lowered vertically under the restriction of the limiting groove, forcing the structure installed at the bottom of the pressure rod to approach the top of the mixing tank for sealing treatment. It can also lift the cover plate to form a gap so that the liquid can be tilted to the right to ensure that the volume of the internal sample solution will not decrease. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4An embodiment of this utility model provides a food testing sample stirring and digestion device for easy discharge, including a base plate 1 and a stirring tank 13. The stirring tank 13 is provided on the right side of the top of the base plate 1, and a base 18 is provided below the base plate 1. A slot 17 is provided on the right side of the inside of the base 18. A bracket 26 is installed between the front and rear of the top center of the base 18. Fixing blocks 16 are welded to the front and rear of the top of the base plate 1, and a handle 19 is installed between the fixing blocks 16 and the bracket 26. Screw holes 20 are provided on the front and rear of the top left of the base 18, and threaded sleeves 22 are fixed on the left side of the front and rear of the base plate 1, and bolts 21 are assembled between the threaded sleeves 22 and the screw holes 20.
[0025] The handle 19 can rotate the fixing block 16 and the base plate 1 in the bracket 26. The fixing block 16 is movably connected to the front and rear ends inside the bracket 26. The bolt 21 can rotate up and down between the threaded sleeve 22 and the screw hole 20. The bolt 21, the threaded sleeve 22 and the screw hole 20 are in the same vertical plane.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, unscrew the bolts 21 at the threaded sleeves 22 at both ends, hold the handle 19 at the front end, and then rotate the fixing block 16 on the substrate 1 at the bracket 26 above the base 18 until the mixing mechanism on the right side of the substrate 1 is in a left-high-right-low posture and guides the liquid out at the slot 17. After that, reset the substrate 1 and other objects and screw the bolts 21 into the screw holes 20 for fixation.
[0027] A bushing 15 is installed between the bottom of the mixing tank 13 and the base plate 1. A cover plate 11 is snapped onto the top of the mixing tank 13. A sealing groove 12 is fixed around the bottom of the cover plate 11. A motor 10 is installed at the center of the top of the cover plate 11. A rotating rod 14 is movably connected to the center of the bottom of the cover plate 11. A pressure rod 5 is horizontally arranged above the cover plate 11. A motor 7 is fixed to the right side of the top of the pressure rod 5. A sleeve block 9 is fixed to the right side of the bottom of the pressure rod 5 and the left side of the top of the cover plate 11 respectively. A rotating block 8 is fixed between the sleeve blocks 9. An upper sleeve 23 is fixed to the left side of the rotating block 8. A lower sleeve 25 is fixed to the lower left corner of the outside of the mixing tank 13. An insert rod 24 is movably inserted between the upper sleeve 23 and the lower sleeve 25.
[0028] The output end of motor 7 passes through the sleeve block 9 and is fixedly connected to the rotating block 8. The output end of motor 10 is fixedly connected to the rotating rod 14. The upper sleeve 23 and the lower sleeve 25 are on the same vertical plane. The upper sleeve 23, the insertion rod 24 and the lower sleeve 25 are inserted together in concentric circles.
[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, after the cover plate 11 is reset by the pressure rod 5, the upper sleeve 23 also approaches the lower sleeve 25 along the insertion rod 24. The motor 2 10 can be started to crush the solid food sample in the mixing tank 13 and speed up the mixing speed. With the rotation of the motor 1 7, the power is transmitted to the cover plate 11 through the rotating block 8. Since the cover plate 11 is locked to the top of the mixing tank 13 through the sealing groove 12, under the connection of the upper sleeve 23, the insertion rod 24 and the lower sleeve 25, the mixing tank 13 is synchronously driven to rotate above the bushing 15.
[0030] A vertical rod 2 is welded to the top left side of the substrate 1, and a lead screw 4 is movably connected between the upper and lower sides of the right side of the vertical rod 2. The outside of the lead screw 4 is fixedly connected to the pressure rod 5. A threaded cylinder 6 is installed on the left side inside the pressure rod 5. A limiting groove 3 is longitudinally provided on the right side surface of the vertical rod 2. The left side of the pressure rod 5 is embedded in the limiting groove 3, and the lead screw 4 is embedded in the threaded cylinder 6.
[0031] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the movement of the pressure rod 5 is determined by the lead screw 4 on the left. By simply holding the top of the lead screw 4, the pressure rod 5 with the threaded cylinder 6 can be vertically raised and lowered under the restriction of the limiting groove 3. This forces the structure installed at the bottom of the pressure rod 5 to approach the top of the mixing tank 13 for sealing treatment, and can also lift the cover plate 11 to form a gap so that liquid can be tilted to the right.
[0032] Working principle: When using this invention, firstly, the sample and water are added to the mixing tank 13. After the cover plate 11 is reset using the pressure rod 5, the upper sleeve 23 also approaches the lower sleeve 25 along the insertion rod 24. The motor 2 10 can then be started to crush the solid food sample in the mixing tank 13, accelerating the mixing speed. In conjunction with the rotation of the motor 1 7, the power is transmitted to the cover plate 11 through the rotating block 8. Because the cover plate 11 is secured to the top of the mixing tank 13 through the sealing groove 12, under the connecting action of the upper sleeve 23, the insertion rod 24, and the lower sleeve 25, the mixing tank 13 is simultaneously driven above the bushing 15. Rotate and mix the materials. At this time, the movement of the pressure rod 5 is determined by the lead screw 4 on the left. Simply hold the top of the lead screw 4, and the pressure rod 5 with the threaded cylinder 6 can be vertically raised and lowered under the restriction of the limiting groove 3. This forces the structure installed at the bottom of the pressure rod 5 to approach the top of the mixing tank 13 for sealing. Finally, unscrew the bolts 21 at the threaded sleeves 22 at both ends, hold the handle 19 at the front end, and then rotate the fixing block 16 on the base plate 1 at the bracket 26 above the base 18 until the mixing mechanism on the right side of the base plate 1 presents a left-high-right-low posture and guides the liquid out at the slot 17.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
