AI Technical Summary
When existing agricultural product pretreatment devices process multiple samples, sample residues can easily contaminate the next sample, leading to frequent disassembly and cleaning of the compaction blocks, which affects processing efficiency.
The hydraulically driven filter press assembly uses a pressure rod to press the sample through a pressure sleeve, and the juice flows into the collection cup through the filter plate without direct contact with the sample. Combined with the design of the support plate and positioning block, it can achieve rapid position adjustment and fixation, improving stability.
This eliminates the need for multiple machine shutdowns for cleaning, improves the efficiency and stability of processing multiple samples, and simplifies the operation process.

[0022] like Figure 1 and Figure 2 As shown, an agricultural product sample pretreatment device includes a base 1 and a filter press assembly 6. A support 2 is mounted on one top end of the base 1, and a hydraulic cylinder 3 is fixed to the top of the support 2. A pressure rod 4 is fixed to the lower end of the hydraulic cylinder 3. A rotating shaft 5 is rotatably connected to the center of the top of the base 1. The filter press assembly 6 is located on the upper end of the rotating shaft 5 and includes a support column 601, a rotating seat 602, a connecting cylinder 603, a filter plate 604, and a pressure sleeve 605. The rotating seat 602 is fixed to the top of the support column 601, and the connecting cylinder 603 is slidably connected to the inner part of the outer end of the rotating seat 602. The lower end of the connecting cylinder 603 is slidably connected to a filter plate 604, and the upper end of the connecting cylinder 603 is slidably connected to a pressure sleeve 605. Since the pressure rod 4 does not directly contact the agricultural products, the next sample can be juiced quickly without having to stop and clean it multiple times. The middle outer side of the connecting cylinder 603 is convex, and the diameter of the bottom opening of the connecting cylinder 603 is smaller than the diameter of the filter plate 604. The hydraulic cylinder 3 is controlled to drive the pressure rod 4 to move down and make it contact the pressure sleeve 605 below, so that the pressure sleeve 605 can press the agricultural products at the bottom, and the sample juice will flow out through the filter plate 604.
[0023] like Figure 1 and Figure 3As shown, a platform 7 is fixed to the outer side of the lower end of the rotating shaft 5, and a positioning groove 8 is provided at the outer top of the platform 7. A liquid collection cup 9 is placed inside the positioning groove 8, which quickly limits the position of the liquid collection cup 9. The support column 601 is hexagonal prism and is slidably connected to the rotating shaft 5. The slidable connection between the support column 601 and the rotating shaft 5 makes disassembly and assembly very convenient. A support plate 10 is fixed to one side of the bracket 2, and the support plate 10 is slidably connected to the rotating seat 602. The support plate 10 supports one end of the rotating seat 602, which helps to enhance the overall stability of the rotating seat 602. A damping rotating shaft 11 is installed at one end of the top of the base 1. Furthermore, a rotating block 12 is connected to the outer side of one end of the damping shaft 11. The damping shaft 11 can enhance the stability of the rotating block 12. A positioning block 13 is fixed to the outer side of the stage 7. The positioning block 13 is U-shaped. By simply moving the rotating block 12 to separate it from the positioning block 13, the position of the rotating seat 602 can be quickly adjusted, facilitating the rapid processing of the next sample. The positioning blocks 13 are equidistantly distributed in a circle around the outer side of the stage 7. The positioning blocks 13 are slidably connected to the rotating block 12. After adjusting the angle, the rotating block 12 is reset so that it engages with the positioning block 13, which can quickly fix the position of the rotating seat 602 and enhance the stability during use.
