Description

Technical Field

[0001] This utility model relates to the field of grain and oil sample pretreatment technology, and in particular to a portable pretreatment box for the detection of mycotoxins in grain and oil samples. Background Technology

[0002] Pretreatment of grain and oil samples for mycotoxin detection refers to a series of physical and chemical treatments performed on the original grain and oil samples before formal testing. The purpose is to effectively extract the target mycotoxins from the complex grain and oil matrix, remove interfering substances, enrich and concentrate the target substances, and finally obtain a clear and pure test solution suitable for instrumental analysis.

[0003] Existing methods for pretreating grain and oil samples typically require the use of different equipment to weigh, crush, extract, and centrifuge the samples separately. This involves a large number of devices that are bulky and inconvenient to carry. It is also inconvenient to use a single device to quickly centrifuge the crushed grain and oil samples, as the crushed samples need to be removed and added to the centrifuge. This process is cumbersome and inconvenient.

[0004] Therefore, there is a need to design a portable pretreatment box for the detection of mycotoxins in grain and oil samples that can facilitate rapid centrifugation after crushing, is easy to carry and use. Utility Model Content

[0005] To overcome the shortcomings of existing methods for pretreating grain and oil samples, which involve numerous, bulky, and inconvenient devices, as well as the cumbersome process of removing and adding the crushed samples to the centrifuge unit after crushing, this invention provides a portable pretreatment box for detecting mycotoxins in grain and oil samples. This box facilitates rapid centrifugation of crushed grain and oil samples, is easy to carry, and convenient to use.

[0006] The technical solution of this utility model is as follows: a portable pretreatment box for detecting mycotoxins in grain and oil samples, comprising a pretreatment box, a lid, buckles, a shoulder strap, an adjusting buckle, hinges, a weighing scale, a display screen, a pipette, a sample compartment, and a centrifugal crushing mechanism. The lid is rotatably connected to the upper part of the pretreatment box via two hinges on the left and right. Two buckles are provided between the lid and the front of the pretreatment box. The shoulder strap is connected to the upper part of the pretreatment box. An adjusting buckle is connected to the right side of the pretreatment box and slides and engages with the shoulder strap. A weighing scale is connected to the upper right part of the pretreatment box. A display screen is connected to the front right part of the pretreatment box. The display screen and the weighing scale are connected by a wire. A pipette is placed in the middle right part of the pretreatment box. A sample compartment is provided at the rear of the pretreatment box. A centrifugal crushing mechanism is provided at the front of the pretreatment box to facilitate rapid centrifugation after crushing the grain and oil samples.

[0007] In one embodiment, the sample chamber has multiple placement holes inside.

[0008] In one embodiment, the centrifugal crushing mechanism includes a crusher body, a motor, a crushing paddle, a crusher cover, an inner cylinder, and a switching component. The crusher body is placed at the front left of the pretreatment box. A motor is connected to the bottom of the crusher body. The motor and the processor are electrically connected through a control module. A crushing paddle is connected to the output shaft of the motor. A crusher cover is rotatably connected to the upper part of the crusher body. An inner cylinder is rotatably connected inside the crusher body.

[0009] In one embodiment, a handle is also included, which is rotatably connected to the outside of the crusher body.

[0010] In one embodiment, the switching assembly includes a ratchet, extrusion pins, and a spring. The ratchet is connected to the lower part of the crushing paddle, and multiple extrusion pins are slidably connected to the ratchet in a circumferentially evenly distributed manner. A rotating ring is provided at the bottom of the inner cylinder, and the rotating ring is rotatably connected to the crusher body. All extrusion pins are in contact with the inner side of the rotating ring, and a spring is connected between each extrusion pin and the ratchet.

[0011] In one embodiment, the system also includes a water tank, a water pump, a corrugated pipe, and a cover. The water tank is connected to the front of the pretreatment tank, the corrugated pipe is connected to the upper side of the water tank via the water pump, and a cover is snapped onto the upper right side of the water tank.

[0012] Beneficial effects: 1. This utility model crushes grain and oil samples by rotating the crushing paddle. The ratchet rotates counterclockwise, which causes the extrusion column to be squeezed between the extrusion column, the ratchet, and the rotating ring. This causes the extrusion column to move a certain distance, and the spring is stretched. At this time, the extrusion column stops moving and drives the inner cylinder to rotate, thus centrifuging the grain and oil samples. This achieves the effect of conveniently crushing grain and oil samples and then quickly centrifuging them. It is also easy to carry and convenient to use.

[0013] 2. This utility model allows you to remove the crusher body by holding the handle, then pick up the corrugated pipe and point it towards the inner cylinder, then start the water pump so that water enters the inner cylinder through the corrugated pipe to clean the inner cylinder. This achieves the effect of conveniently adding cleaning water to the inner cylinder and facilitating its cleaning. Attached Figure Description

The box lid 2 is rotatably connected to the upper part of the pretreatment box 1 via two hinges 6. Two buckles 3 are provided between the box lid 2 and the front of the pretreatment box 1. The shoulder strap 4 is connected to the upper part of the pretreatment box 1, and the adjusting buckle 5 is connected to the right side of the pretreatment box 1. The adjusting buckle 5 is slidably engaged with the shoulder strap 4. A weighing scale 7 is connected to the upper right of the pretreatment box 1. A display screen 8 is connected to the front right of the pretreatment box 1. The display screen 8 and the weighing scale 7 are connected by wires. A pipette 9 is placed in the middle right of the pretreatment box 1. A water tank 10 is connected to the front of the pretreatment box 1. A corrugated pipe 12 is connected to the upper side of the water tank 10 through a water pump 11. A cover 13 is snapped onto the upper right side of the water tank 10. A sample compartment 14 is provided at the rear of the pretreatment box 1. The sample compartment 14 has thirty-two placement holes inside for easy placement of sample tubes. A centrifugal crushing mechanism 15 is provided at the front of the pretreatment box 1.

[0022] like Figures 3-5As shown, the centrifugal crushing mechanism 15 includes a crusher body 151, a motor 152, a crushing paddle 154, a crusher cover 155, a handle 156, an inner cylinder 157, and a switching component. The crusher body 151 is placed at the front left of the pretreatment box 1. The motor 152 is connected to the bottom of the crusher body 151. The motor 152 and the processor are electrically connected through a control module. The crushing paddle 154 is connected to the output shaft of the motor 152. The crusher cover 155 is rotatably connected to the upper part of the crusher body 151. The handle 156 is rotatably connected to the outside of the crusher body 151. The inner cylinder 157 is rotatably connected to the inside of the crusher body 151.

[0023] like Figure 5 As shown, the switching assembly includes a ratchet 153, extrusion pins 158, and springs 159. The ratchet 153 is connected to the lower part of the crushing paddle 154. Nine extrusion pins 158 are evenly distributed and slidably connected on the ratchet 153. A rotating ring is provided at the bottom of the inner cylinder 157. The rotating ring is rotatably connected to the crusher body 151. All extrusion pins 158 are in contact with the inner side of the rotating ring.

Once the specified weight is reached, add the grain and oil sample into the crusher body 151, then rotate to close the crusher lid 155. Then start the motor 152, which drives the crushing paddle 154 and ratchet 153 to rotate clockwise. The crushing paddle 154 crushes the grain and oil sample. After the grain and oil sample is crushed, extract the solvent. The agent is added into the inner cylinder 157, and then the motor 152 is started in reverse, which drives the ratchet 153 to rotate counterclockwise, so that the squeezing column 158 is squeezed between the ratchet 153 and the rotating ring, causing the squeezing column 158 to move a certain distance. The spring 159 is stretched, and at this time the squeezing column 158 can no longer move. The ratchet 153 continues to rotate, which will drive the inner cylinder 157 to rotate, and the grain and oil sample is centrifuged, so that the solid matter settles to the bottom of the inner cylinder 157. This makes it convenient to quickly centrifuge the grain and oil sample after crushing, and it is easy to carry and use. After centrifugation, the upper clear liquid is taken out by the pipette 9 and then transferred to the sample test tube placed in the sample chamber 14. When the inner cylinder 157 needs to be cleaned, the crusher body 151 can be removed by holding the handle 156, and then the corrugated pipe 12 can be picked up and placed towards the inner cylinder 157. Then the water pump 11 can be started so that water can enter the inner cylinder 157 through the corrugated pipe 12 to clean the inner cylinder 157. This makes it easy to add cleaning water to the inner cylinder 157 and facilitates cleaning of the inner cylinder 157.
