Description

Technical Field

[0001] This utility model belongs to the field of crop research technology, and in particular relates to a sample preparation device for crop research. Background Technology

[0002] In scientific research fields such as crop variety breeding, pest and disease control, and physiological and biochemical analysis, the cleanliness and safety of sample preparation directly affect the accuracy and reliability of experimental data. Crop samples often have contaminants such as soil, pesticide residues, and microbial colonies adhering to their surfaces. Incomplete cleaning can not only interfere with subsequent testing indicators but also lead to cross-contamination, affecting the scientific validity of experimental results. While traditional manual cleaning methods can achieve a certain level of cleanliness, they suffer from low efficiency, high labor intensity, and reliance on operational experience for cleaning effectiveness, making them unsuitable for processing large-scale scientific research samples.

[0003] Furthermore, in existing crop sample preparation processes, the cleaning and disinfection steps are usually independent, requiring the cleaned samples to be transferred to dedicated disinfection equipment for further processing. This not only increases the number of steps and time costs but also may introduce the risk of secondary contamination during the transfer process. Especially for living tissue samples, multiple transfers may lead to a decrease in sample viability, affecting the accuracy of subsequent physiological indicator detection. Currently, there is a lack of automated sample preparation devices on the market that can achieve omnidirectional sample flipping during the cleaning process to improve ultrasonic cleaning efficiency, and integrate cleaning and disinfection functions into one unit.

[0004] To address these issues, we provide a crop research sample preparation device. Utility Model Content

[0005] The purpose of this invention is to provide a sample preparation device for crop research, which solves the problems of low cleaning efficiency and high labor intensity in the prior art by combining the cleaning component and the flipping component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a sample preparation device for crop research, comprising a cleaning component, with adjustment components fixedly connected to both sides of the cleaning component, and a flipping component fixedly connected to one side of the adjustment component. The cleaning component includes a cleaning tank, with an ultrasonic cleaner fixedly connected to the bottom of the inner cavity of the cleaning tank, and a filter screen fixedly connected to the inner cavity of the cleaning tank above the ultrasonic cleaner. The adjustment component includes an electric push rod one fixedly connected to one side of the cleaning tank, and a connecting frame fixedly connected to the top of the electric push rod one. The flipping component includes a mounting plate fixedly connected to the bottom of the connecting frame, with electric push rod two fixedly connected to both sides of the top of the mounting plate, and a connecting plate fixedly connected to the output end of the electric push rod two. A dual-output shaft motor is fixedly connected to the bottom of the mounting plate, with both ends of the dual-output shaft motor extending through to the outside of the connecting plate and fixedly connected to gear transmission components. A placement basket is fixedly connected to one end of the gear transmission component.

[0008] The present invention is further provided that each of the four corners of the bottom of the cleaning tank is fixedly connected with a pad, and the bottom of the pad is provided with anti-slip texture. The anti-slip pad increases the friction coefficient between the device and the table surface, avoids displacement caused by ultrasonic vibration, and ensures the stability of equipment operation.

[0009] The present invention is further configured such that a drain pipe is connected to the bottom of one side of the cleaning tank, and a valve is fixedly connected to the inner cavity of the drain pipe. The drain pipe is connected to the lowest point of the bottom of the cleaning tank, and the built-in ball valve can quickly discharge sewage. In conjunction with the filter screen, solid impurities are intercepted, which facilitates subsequent waste liquid treatment.

[0010] The present invention is further configured such that the gear transmission component includes a bevel gear one fixedly connected to the dual output shaft motor, a bevel gear two meshing on the surface of the bevel gear one, a transmission shaft fixedly connected to the bottom of the bevel gear two, a bevel gear three fixedly connected to the bottom of the transmission shaft, a bevel gear four meshing on the surface of the bevel gear three, and a side of the bevel gear four fixedly connected to the placement basket. The four-stage bevel gear transmission structure achieves 90° power steering, converting the horizontal rotation of the dual output shaft motor into the vertical flipping of the placement basket. The structure is compact and has high transmission efficiency.

[0011] The present invention is further configured such that a bearing seat is fixedly connected to the surface of the transmission shaft, one side of the bearing seat is fixedly connected to the surface of the connecting plate, and the bearing seat fixes the middle part of the transmission shaft, thereby reducing radial sway during gear transmission and improving the stability and service life of the flipping mechanism.

[0012] The present invention is further configured such that a through hole is provided on the top of one side of the connecting plate, and a gap is left between the bevel gear and the through hole. The gap between the through hole and the bevel gear ensures the smoothness of the connecting plate when it moves.

[0013] The present invention is further configured such that a protective box is fixedly connected to the surface of the connecting plate and outside the bevel gears three and four. The protective box covers the bevel gears three and four to prevent the cleaning fluid from splashing and corroding the gears, and at the same time facilitates the observation of the transmission status.

[0014] The present invention is further configured such that the placement basket and the connecting plate are fixedly connected by bearings, a sliding rod is fixedly connected to one side of the connecting plate, and a sliding sleeve is fitted on the surface of the two sliding rods. The top of the sliding sleeve is fixedly connected to the bottom of the dual output shaft motor. The sliding rod and sliding sleeve provide lateral support for the connecting plate, ensuring its stability when moving left and right.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model, through the innovative design of integrating an ultrasonic cleaner and a flip-up placement basket into the cleaning box, enables three-dimensional cleaning of crop samples. The high-frequency vibration generated by the ultrasonic cleaner can create a cavitation effect through the water medium, effectively removing tiny contaminants such as soil and pesticide residues from the sample surface. The gear transmission component driven by the dual-output shaft motor can rotate the placement basket 360°, so that complex surface structures such as leaf wrinkles and fruit depressions can be fully exposed within the ultrasonic range, solving the problem of cleaning blind spots in traditional static ultrasonic cleaning. The electric push rod can precisely control the depth of the placement basket immersed in the cleaning solution, adapting to the cleaning needs of different types of crops while avoiding sample damage.

[0017] 2. This utility model device integrates cleaning and subsequent processing steps through modular integrated design. The drain pipe at the bottom of the cleaning tank can quickly discharge wastewater containing pollutants, while the protective box on the outside of the gear transmission component of the flipping component can prevent the cleaning fluid from corroding the transmission components. The sample does not need to be transferred from cleaning to disinfection, avoiding the risk of secondary contamination caused by multiple handling in the traditional process. Especially for live tissue samples, reducing transfer loss can effectively maintain their cell viability and ensure the accuracy of physiological and biochemical tests. Attached Figure Description

An electric push rod 21 is vertically fixed in the middle of the outer walls on both sides of the cleaning tank 11. Its output shaft is connected to the center of the bottom surface of the connecting frame 22 through a flange, which can drive the connecting frame 22 to reciprocate in the vertical direction.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, pads are fixedly connected to the four corners of the bottom of the cleaning tank 11. The bottom of the pads is provided with anti-slip texture. A drain pipe is connected to the bottom of one side of the cleaning tank 11. A valve is fixedly connected to the inner cavity of the drain pipe.

A sliding sleeve 39 is fitted on the surface of the two sliding rods 38. The top of the sliding sleeve 39 is fixedly connected to the bottom of the dual output shaft motor 34.

[0031] Specifically: the anti-slip pad increases the friction coefficient between the device and the table surface, avoiding displacement caused by ultrasonic vibration and ensuring the stability of equipment operation; the drain pipe connects to the lowest point of the bottom of the cleaning tank 11, and the built-in ball valve can quickly discharge sewage; the filter screen 13 intercepts solid impurities, facilitating subsequent waste liquid treatment; the four-stage bevel gear transmission structure achieves 90° power steering, converting the horizontal rotation of the dual output shaft motor 34 into the vertical flipping of the basket 36; the structure is compact and has high transmission efficiency; the bearing seat fixes the middle of the transmission shaft 353, reducing radial sway during gear transmission and improving the stability and service life of the flipping mechanism; the through hole and the bevel gear 351 have a reserved gap to ensure the smooth movement of the connecting plate 33; the protective box 37 covers the bevel gears 354 and 355 to prevent cleaning liquid from splashing and corroding the gears, while also facilitating the observation of the transmission status; the slide rod 38 and the sliding sleeve 39 provide lateral support for the connecting plate 33, ensuring its stability when moving left and right.

[0032] The working principle of this utility model is as follows: A crop sample is placed in the placement basket 36. The retraction of the electric push rod 32 causes the two connecting plates 33 to move relative to each other, thus closing the two placement baskets 36 together. The electric push rod 21 drives the connecting frame 22 to descend, immersing the placement basket 36 in the cleaning solution in the cleaning tank 11. The dual-output shaft motor 34 starts, driving the placement basket 36 to reciprocate through the gear transmission component 35. Simultaneously, the ultrasonic cleaner 12 emits high-frequency vibrations. The cavitation effect combined with mechanical tumbling achieves comprehensive cleaning of the sample, lasting 5-10 minutes. After cleaning, the electric push rod 21 raises the connecting frame 22 to a high position, and the drain valve is opened. Wastewater containing impurities is filtered through the filter screen 13 and discharged. If disinfection is required, a disinfectant solution can be injected into the cleaning tank 11, and the tumbling and cleaning process can be repeated. After processing, the electric push rod 32 extends, separating the two placement baskets 36, and the sample is removed for subsequent testing.
