Description

Technical Field

[0001] This utility model relates to the field of food extraction oscillators, and in particular to a food pesticide residue extraction oscillator. Background Technology

[0002] The food pesticide residue extraction shaker is a key pretreatment device in the field of food testing. It is used to quickly and efficiently extract pesticide residues from food samples, providing a reliable test solution for subsequent chromatographic and mass spectrometric analysis. Its core function is to accelerate the chemical reaction between the sample and the extraction solvent through shaking and mixing, thereby improving extraction efficiency and uniformity. This device is widely used in environmental analysis, food science, agriculture and pesticides, soil research, water quality monitoring, petrochemicals and other fields.

[0003] However, the existing equipment has the following shortcomings: when the existing equipment vibrates, the material tube is easy to detach from the inside of the placer, causing the material tube to fall to the ground, resulting in breakage and damage to the material tube, making it difficult to extract.

[0004] Therefore, we propose a food pesticide residue extraction shaker to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the material pipe easily detaches from the equipment and falls to the ground and breaks during use. This invention provides a food pesticide residue extraction vibrator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a food pesticide residue extraction shaker, comprising a main body, a placement device, a material pipe, an adjuster, a support block, and a limiting device. The support block is fixedly connected to the lower surface of the main body, the placement device is installed on the upper surface of the main body, the material pipe is inserted into the interior of the placement device, the adjuster is installed on the side of the main body, and the limiting device is fixedly installed on the side of the placement device. The limiting device includes a limiting plate and a limiting block. The limiting block is fixedly connected to the side of the placement device, the limiting plate is installed above the placement device, a movable plate is fixedly connected to the side of the limiting plate, the movable plate is slidably connected inside the limiting block, a stop block is fixedly connected to the lower side of the movable plate, an adjustment groove is formed on the surface of the movable plate, and a pull rod is slidably connected inside the limiting block.

[0007] Furthermore, an adjusting rod is fixedly connected to the side of the pull rod near the limiting block. The adjusting rod is inserted into the inside of the adjusting groove. By setting the adjusting rod, the moving plate can be limited, reducing the situation where the moving plate is difficult to limit during use.

[0008] Furthermore, a first spring is fixedly connected to both ends of the pull rod. The end of the first spring away from the pull rod is fixedly connected to the inside of the limiting block. The first spring is provided to facilitate the application of a restoring force to the pull rod.

[0009] Furthermore, a handle is fixedly connected to the side of the pull rod away from the limiting block, and the handle facilitates the movement of the pull rod.

[0010] Furthermore, an anti-spillage device is fixedly installed on the upper surface of the limiting plate. The anti-spillage device includes a blocking plate and a positioning block. The positioning block is fixedly connected to the upper surface of the limiting plate. The blocking plate is engaged with the upper end of the material pipe. A rotating rod is fixedly connected to the upper end of the positioning block. A spring plate is rotatably connected to the surface of the rotating rod. By setting the blocking plate, the material pipe can be blocked, reducing the possibility of liquid overflowing from the inside of the material pipe during use.

[0011] Furthermore, a retaining ball is fixedly connected to the lower surface of the end of the elastic plate away from the rotating rod, and a retaining groove is provided on the upper surface of the blocking plate. The elastic plate is provided to facilitate the limiting movement of the retaining ball.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a limiting device, the material tube is effectively limited, which plays a role in limiting and stabilizing the material tube during vibration. This reduces the situation where the material tube is easily detached from the placer during vibration in existing equipment, resulting in the material tube falling out of the placer and falling to the ground, causing the material tube to break and be damaged. This limiting device realizes the rapid positioning and stable clamping of the material tube, and improves the stability of the material tube during the vibration extraction process of the equipment.

[0015] 2. In this utility model, by setting an anti-spillage device, during the oscillation process, the blocking plate is tightly attached to the inner wall of the material pipe, and with the pressing force of the elastic plate, the situation of the extract overflowing from the material pipe and scattering on the equipment surface due to violent shaking is reduced, thus contaminating the equipment.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a food pesticide residue extraction shaker, including a main body 1, a placement device 2, a material tube 3, an adjuster 4, a support block 5 and a limiting device 6. The support block 5 is fixedly connected to the lower surface of the main body 1, the placement device 2 is installed on the upper surface of the main body 1, the material tube 3 is inserted and connected to the inside of the placement device 2, and the adjuster 4 is installed on the side of the main body 1.

[0023] The main body 1 integrates a high-precision motor and intelligent control system. The motor is a brushless DC motor, characterized by low noise and high speed stability, enabling precise control of oscillation frequency and amplitude. The placement device 2 is made of high-strength, corrosion-resistant engineering plastic and has multiple placement slots inside to accommodate material tubes 3 of different specifications. The slot walls are made of flexible cushioning material to reduce wear on the material tubes 3 during oscillation. The material tubes 3 are made of high borosilicate glass, which has good chemical stability and high temperature resistance, and can safely hold the extraction liquid. The regulator 4 is a touch-screen operation panel equipped with a high-definition display screen, which allows for intuitive setting of parameters such as oscillation time and frequency. The support block 5 is made of rubber with anti-slip texture on the bottom, which can effectively reduce shock and prevent the equipment from shifting during oscillation.

[0024] The following section will explain the specific settings and functions of the limiting device 6 and the anti-spillage device 7.

[0025] In this embodiment: the limiting device 6 is fixedly installed on the side of the placer 2. The limiting device 6 includes a limiting plate 61 and a limiting block 62. The limiting block 62 is fixedly connected to the side of the placer 2. The limiting plate 61 is installed above the placer 2. The limiting plate 61 is made of lightweight aluminum alloy, which is strong and lightweight. Its length is adapted to the placer 2 and can cover multiple material tubes 3 to achieve batch limiting. A movable plate 63 is fixedly connected to the side of the limiting plate 61. The movable plate 63 is slidably connected inside the limiting block 62. A stop block 65 is fixedly connected to the lower side of the movable plate 63. An adjustment groove 64 is opened on the surface of the movable plate 63. A pull rod 66 is slidably connected inside the limiting block 62.

[0026] Specifically, an adjusting rod 68 is fixedly connected to the side of the pull rod 66 near the limiting block 62, and the adjusting rod 68 is inserted into the adjusting groove 64.

[0027] In this embodiment, by setting the adjusting rod 68, the moving plate 63 can be limited, reducing the difficulty of limiting the moving plate 63 during use.

[0028] Specifically, the two ends of the pull rod 66 are fixedly connected to a first spring 67. The end of the first spring 67 away from the pull rod 66 is fixedly connected to the inside of the limiting block 62. The first spring 67 is provided to facilitate the application of a reset force to the pull rod 66.

[0029] Specifically, a handle 69 is fixedly connected to the side of the pull rod 66 away from the limiting block 62, and the handle 69 is provided to facilitate the movement of the pull rod 66.

[0030] In this implementation scheme: a spill prevention device 7 is fixedly installed on the upper surface of the limiting plate 61. The spill prevention device 7 includes a blocking plate 71 and a positioning block 72. The positioning block 72 is fixedly connected to the upper surface of the limiting plate 61. The blocking plate 71 is engaged with the upper end of the material pipe 3. The blocking plate 71 is made of food-grade silicone material, which has good flexibility and sealing performance. Its shape is precisely matched with the opening of the material pipe 3, which can tightly block the opening. A rotating rod 73 is fixedly connected to the upper end of the positioning block 72. An elastic plate 74 is rotatably connected to the surface of the rotating rod 73. The elastic plate 74 is made of spring steel, which has good elasticity and strength. Its length and angle are designed so that the locking ball 75 can be accurately locked into the locking groove 76 after rotation.

[0031] In this embodiment: by setting the blocking plate 71, the material pipe 3 can be blocked, reducing the possibility of liquid overflowing from the inside of the material pipe 3 during use.

[0032] Specifically, a retaining ball 75 is fixedly connected to the lower surface of the end of the elastic plate 74 away from the rotating rod 73, and a retaining groove 76 is provided on the upper surface of the blocking plate 71. The elastic plate 74 is provided to facilitate the limiting movement of the retaining ball 75.

[0033] Specifically, the ball 75 is internally engaged with the slot 76, and a handle 77 is fixedly connected to the upper surface of the blocking plate 71.

[0034] Working principle: When using the equipment, the user places the material tube 3 into the placement groove inside the placement device 2, and then starts the main body of the equipment 1 to drive the placement device 2 to vibrate, thus vibrating and extracting the extractant in the material tube 3 inside the placement device 2. When using the equipment, after the user puts the material tube 3 into the placement device 2, they pull the handle 69 to move the pull rod 66, which moves the adjusting rod 68 into the adjusting groove 64 on the surface of the moving plate 63. The movement of the pull rod 66 causes the first spring 67 to stretch, generating elastic force. The moving plate 63 is then released, pulling the limiting plate 61 upward. After the limiting plate 61 is engaged with the upper side of the material tube 3, the handle 69 is released. The first spring 67 resets, causing the pull rod 66 to move and the adjusting rod 68 to move and insert into the adjusting groove 64 on the surface of the moving plate 63, fixing the limiting plate 61 and limiting the material tube 3. By setting the limiting device 6, the material tube 3 is effectively limited, which plays a role in limiting and stabilizing the material tube 3 during vibration. This reduces the situation where the material tube 3 is easily detached from the placer 2 during vibration, causing it to fall to the ground and break. This limiting device 6 realizes the rapid positioning and stable clamping of the material tube 3, improving the stability of the material tube 3 during the vibration extraction process.

[0035] After the user fixes the material tube 3 to the inside of the placer 2, the blocking plate 71 and the limiting plate 61 are placed on the surface to block the inside of the material tube 3. Then, the elastic plate 74 is rotated, and the locking ball 75 is locked into the locking groove 76 of the blocking plate 71 under the elastic action of the elastic plate 74, fixing the blocking plate 71 to the upper end of the material tube 3 and sealing the pipe opening. By setting the anti-spillage device 7, during the oscillation process, the blocking plate 71 is tightly attached to the inner wall of the material tube 3. With the pressing force of the elastic plate 74, the situation of the extract overflowing from the material tube 3 due to violent shaking and scattering on the equipment surface, thus contaminating the equipment, is reduced. This anti-spillage device 7 realizes the blocking of the material tube 3 and improves the practicality of the equipment.
