Description

Technical Field

[0001] The invention relates to the field of agricultural seed testing instruments, and in particular to a seed testing instrument integrating screening, counting and weighing. Background Art

[0002] In agricultural breeding and seed quality testing, seed testing instruments need to simultaneously complete screening, counting and weighing operations, but existing equipment has significant defects. When screening, the outer skin wrapped around the seeds is easily covered by the seeds, which brings inconvenience when screening seeds. The screening of the vibrating screen will cause violent collisions between seeds, which may cause seed damage. If the outer skin is not removed, it will affect the observation of the seeds. Although there are existing counters for counting, the counters will be affected by the environment after long-term use, and the accuracy will be affected. How to use the same device for screening, weighing and counting is an important problem that needs to be solved. Therefore, it is urgent to design a seed testing instrument that integrates screening, counting and weighing to solve the problem of seed screening, counting and weighing by the seed testing instrument. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a seed testing instrument which integrates screening, counting and weighing.

[0004] This tester adopts modular integrated design, mainly composed of screening system, power transmission system, airflow auxiliary system and weighing module. The specific technical solution is as follows:

[0005] The main body of the device includes a support tube and a U-shaped base. The base has symmetrical sockets and embedded rubber sleeves. A hollow support frame is vertically fixed on the front middle side of the support tube, and its lower end is connected to the base through a U-shaped plug-in frame. A torsion spring is set at the connection between the plug-in frame and the support frame to achieve overall inclination adjustment. Three sets of connectable arc-shaped baffles are set on the inner wall of the support tube. The baffles are connected by spiral springs to form a dynamic screen cylinder. The inner surface of the baffle is covered with a nylon friction layer and is made of transparent acrylic material. A rotating drum is coaxially arranged inside the support tube, and a screening net is installed at the rear end. The front end is rigidly connected to the wheel in the center of the support frame through a connecting rod.

[0006] The motor is installed at the upper left corner of the support cylinder through a fixed rod. Its output shaft drives the third rotating shaft and the second pulley, which rotates through the second belt and the second rotating shaft in the middle of the support frame. The first pulley at the front end of the second rotating shaft is connected to the first rotating shaft through the first belt. A frosted rubber friction wheel is installed at the end of the first rotating shaft. The friction wheel contacts the outer surface of the baffle to generate high-frequency vibration. The rocker arm is hinged on the side of the wheel to form an eccentric vibration source, thereby realizing the coordinated operation of the centrifugal screening of the rotating drum and the dynamic vibration of the baffle.

[0007] The first end cover is plugged into the support frame, and a box is installed on its surface. The built-in first air pump conveys airflow into the hollow support frame through the connecting pipe, and the airflow enters the interior of the drum through the support frame; the second air pump is fixed on the ventilation plate and sprays directional airflow into the screening area through the ventilation pipe, forming an annular airflow field in conjunction with the arc-shaped airbag to effectively remove dust and light impurities.

[0008] The second end cover is plugged into the support frame, and a weighing platform is integrated on the back of the frame. After screening, the grains fall into the weighing platform through the retaining net to complete automatic weighing. The inclination angle of the device can be adjusted through multi-level plug-in between the bracket and the base socket, and the torsion spring can be used to achieve stepless locking of the inclination angle from 0° to 15°, which can meet the screening needs of seeds with different fluidity.

[0009] The motor drives the drum to rotate at high speed to generate centrifugal force. The friction wheel and the baffle vibrate to form a composite screening action. The first air pump airflow penetrates from the inside of the drum to the outside, and the second air pump airflow impacts the screen surface from the outside. The dual airflows work together to remove impurities; qualified grains fall into the weighing platform through the baffle, realizing a closed loop of the entire screening-counting-weighing process.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The present invention cooperates with the fork frame and the base to make the base of the seed tester a plug-in structure, which is more convenient to install. The movable cooperation between the plug frame and the support frame can adjust the angle of the seed tester, which is convenient for weighing seeds. Through the setting of the first air pump and the second air pump, the seeds in the rotating drum can be blown and sucked to make the seeds distributed in the mesh of the rotating drum, which is convenient for quickly counting and screening the seeds, and the morphology of the seeds can be observed. By setting the baffle and the support cylinder to be transparent, it is convenient to observe the internal situation and the seeds. Through the setting of the friction layer, the friction of the friction layer on the seeds can be used to remove the residual outer skin of the seeds, which is convenient for observing the seeds, and the setting of the airbag plays a buffering role. Through the setting of the hydraulic cylinder, the hydraulic cylinder reciprocates and can repeatedly push the baffle, so that the friction layer on the baffle intermittently contacts the seeds sleeved in the hole on the rotating drum, which is convenient for removing impurities on the seed surface and convenient for observation. The weighing platform facilitates the weighing of seeds. The invention integrates screening, counting and weighing into one, all of which adopt mechanical methods, thus avoiding the influence of the environment on the traditional screening and counting methods, and completing the screening, counting and weighing of seeds.
