Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product detection related equipment, and specifically relates to a sample chopping device for agricultural product detection. Background Technique

[0002] Agricultural products are an important part of people's daily diet, and their quality and safety are directly related to the health of consumers. Through detection, potential food safety problems can be discovered and prevented in a timely manner, ensuring that the agricultural products consumed by consumers are safe and protecting the health rights and interests of consumers. The detection of agricultural product quality and safety can guarantee the quality of agricultural products and improve market competitiveness. When consumers have full trust in the quality of agricultural products, the brand image is enhanced, and the market competitiveness is naturally increased. This helps to promote the sustainable development of the agricultural industry and enables agricultural products to occupy a more favorable position in the market.

[0003] Before detecting agricultural products, it is a common pretreatment step to chop the samples.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] A sample chopping device for agricultural product detection, comprising:

[0028] A bottom plate 1 and a sample box 4 for placing samples; after the sample box 4 is filled with samples, it is placed on the bottom plate 1. A bracket 2 is provided on the bottom plate 1, a top plate 5 is provided at the upper end of the bracket 2, a lifting plate 7 is provided at the bottom of the top plate 5, and the lifting plate 7 is driven by a lifting cylinder 6 to move up and down. The lifting plate 7 is arranged in a U shape, and multiple groups of tool holders 15 are distributed between the two arms of the lifting plate 7. A blade 17 for cutting the sample is installed at the bottom of the tool holder 15; lifting cylinders 6 are symmetrically installed on the top plate 5, and the lower end of the telescopic rod of the lifting cylinder 6 penetrates through the top plate 5 and is fixedly connected to the top of the lifting plate 7 to drive the lifting plate 7 to move up and down.

[0029] It further includes an adjusting mechanism for adjusting the distance between adjacent blades 17; the adjusting mechanism includes a first sliding plate 9, a fixed seat 11 and a first sliding seat 12. The first sliding plate 9 is located between the two arms of the lifting plate 7, the fixed seat 11 is located in the middle of the first sliding plate 9, the first sliding seats are symmetrically arranged on both sides of the fixed seat 11 and the sliding seats are slidably sleeved on the first sliding plate 9. The fixed seat 11 and the first sliding seats 12 are sequentially connected and driven by a telescopic cross frame 20 so that the first sliding seats 12 on both sides of the fixed seat 11 can slide to change the distance, and the telescopic cross frame 20 is driven by a telescopic cylinder 8.

[0030] By placing the sample box 4 on the bottom plate 1, a lifting cylinder 6 is installed on the top plate 5 of the bracket 2 to drive the lifting plate 7 below the top plate 5. Multiple groups of tool holders 15 are distributed at the bottom of the lifting plate 7, and blades 17 are installed on the tool holders 15. At the same time, an adjusting mechanism for adjusting the distance between adjacent blades 17 is also provided. The telescopic cylinder 8 drives the telescopic cross frame 20 to realize the distance change between the blades 17. In actual use, the product is placed in the sample box 4 and placed on the bottom plate 1. The lifting cylinder 6 is started to drive the lifting plate 7 to descend, and the blade 17 can cut up the product in the sample box 4.

[0031] At the same time, because an adjusting mechanism including a fixed seat 11, a first sliding seat 12 and a first sliding plate 9 is provided, the fixed seat 11 and the first sliding seat 12 are connected by a telescopic cross frame 20, and the telescopic cylinder 8 can drive the telescopic cross frame 20. Therefore, the distance between adjacent blades 17 can be adjusted by the telescopic cylinder 8, so that the device can cut the product into different thicknesses according to actual needs.

[0032] Wherein, the width of the blade 17 is the same as the inner cavity width of the sample box 4, the height of the blade 17 is 3 - 5 cm greater than the inner cavity depth of the sample box 4, and a positioning fence 3 for placing the sample box 4 is provided on the bottom plate 1.

[0033] The design of the positioning baffle 3 can fix and position the sample box 4, avoiding the displacement of the sample box 4 during the cutting process, improving the cutting accuracy. At the same time, the correspondence between the blade 17 and the sample box 4 can ensure complete cutting. The stroke of the lifting cylinder 6 can be controlled by programming. When the blade 17 touches the inner bottom of the sample box 4, the lifting cylinder 6 reaches the maximum stroke;

[0034] Generally speaking, the structure of this device is simple and easy to use. The sample is chopped by slicing and then detected. While ensuring the processing efficiency, it avoids excessive crushing of the sample, ensuring the accuracy of the detection results. At the same time, the slice thickness can be flexibly adjusted according to the detection needs, with high practicability and application scope.

A second slide seat 13 is slidably sleeved on the second slide plate 10, and the second slide seat 13 corresponds to the fixed seat 11 and the first slide seat 12. A telescopic cylinder 8 is installed on the outer wall of one side of the lifting plate 7. An adjusting plate 19 is provided between the first slide seat 12 and the second slide seat 13 closest to the telescopic cylinder 8. The piston rod end of the telescopic cylinder 8 penetrates through the lifting plate 7 and is fixedly connected to the adjusting plate 19 to drive the telescopic cross frame 20.

[0037] Through such a design, the telescopic cylinder 8 can drive the first slide seat 12 and the second slide seat 13 simultaneously through the adjusting plate 19, which can not only play a good guiding role but also improve the fixing ability of the tool holder 15, enhancing the stability and accuracy of the equipment;

[0038] Furthermore, please refer to Figure 3 :

[0039] Connection plates 14 are provided at the bottoms of the fixed seat 11, the first slide seat 12, and the second slide seat 13. The lower ends of the connection plates 14 are connected to the tool holder 15, and there are two groups of opposite connection plates 14 at the top of each group of tool holders 15. The blade 17 is installed at the bottom of the tool holder 15 through fixing screws. A slot 16 for inserting the blade 17 is provided at the bottom of the tool holder 15, and fixing holes 18 for installing the fixing screws are correspondingly provided on the blade 17 and the slot 16.

[0040] Through such a design, the blade 17 and the tool holder 15 can be quickly installed and used. When a certain group of blades 17 is worn, the blade 17 can be removed and replaced, improving the convenience of using the equipment.
