Problems solved by technology

[0003] In the process of agricultural breeding, it is necessary to select seeds according to the size of the seeds. The commonly used method is to screen the seeds to obtain seeds that meet the size requirements. However, the current seed screening device has a low screening efficiency for seeds and cannot realize The rapid screening effect of the seeds affects the efficiency of seed selection. For this reason, a seed screening device for agricultural breeding is now provided to solve the above problems

Embodiment 1

[0021] see Figure 1-3 , a seed screening device for agricultural breeding, comprising a support frame 1, a drive motor 7 is fixedly installed on the left side wall of the support frame 1, and a drive shaft 6 extending into the support frame 1 is fixedly installed on the output shaft of the drive motor 7 coaxially . The drive motor 7 is used as the power source of the device for driving the drive shaft 6 to rotate, and the drive motor 7 may preferably be a servo motor.

[0022] A screen trough 17 is fixedly installed in the support frame 1, a screen plate 15 is horizontally slidable on the screen trough 17, a worm 21 is fixedly installed on the end of the drive shaft 6 coaxially, and a worm 21 is rotatably connected to it below the worm 21. The worm gear 8 is provided with a transmission pendulum 9 rotating on the support frame 1, and the upper half of the transmission pendulum 9 is provided with a waist-shaped hole II23, and the front of the worm gear 8 is eccentrically fixe...

Embodiment 2

[0026] On the basis of Embodiment 1, in addition, a bearing plate 2 is horizontally and fixedly installed in the support frame 1, and a driven shaft 11 is rotatably arranged on the bearing plate 2, and the bottom of the driven shaft 11 is coaxially fixedly installed with The elliptical cam 16 that the wall abuts against, and the bottom of the elliptical cam 16 is fixedly equipped with a brush 14 that is in contact with the upper surface of the screening plate 15 .

[0027] Further, the driven bevel gear 4 is coaxially and fixedly mounted on the upper end of the driven shaft 11 , and the driving bevel gear 5 meshingly connected with the driven bevel gear 4 is fixedly mounted on the right end of the worm 21 .

[0028] Further, the inner side wall of the screening tank 17 is symmetrically provided with two pressing plates 13 whose bottom abuts against the upper surface of the screening plate 15 , and a return spring 19 is fixedly installed between the pressing plates 13 and the in...

Embodiment 3

[0031] On the basis of embodiment 2, in addition, the hot air blower 3 is fixedly installed on the bearing plate 2, and the air injection disc 20 communicated with the hot air blower 3 is fixedly installed on the lower surface of the bearing plate 2. The disk 20 is oriented vertically downwards.

[0032] The hot air that the provided hot air blower 3 produces is sprayed downwards to the screening tank 17 through the air jet disc 20, which plays a role in drying the seeds in the screening tank 17, and the moisture between the seeds is volatilized, avoiding the gap between the seeds Mutual bonding improves the degree of dispersion of seeds and the efficiency of screening is further improved.

[0033] Further, a movable door is provided on the side wall of the screening tank 17, and after the screening is finished, the seeds in the screening tank 17 can be easily taken out by opening the movable door.

Abstract

The invention relates to the technical field of agricultural machinery and discloses a seed screening device for agricultural seed breeding. The seed screening device comprises a supporting frame, a driving motor is fixedly mounted on the left side wall of the supporting frame, a driving shaft extending into the supporting frame is coaxially fixedly mounted on an output shaft of the driving motor,a transmission pin II which slidably penetrates an elongated hole II is eccentrically and fixedly mounted on the front face of a worm gear, the lower half portion of a transmission swing rod is provided with an elongated hole I, and a transmission pin I which slidably penetrates an elongated hole I is fixedly mounted at the left end of a screen plate. The transmission swing rod swings to drive the screen plate to reciprocate transversely, and accordingly seed screening effects of the screen plate are improved; a driven shaft rotates to drive an elliptic cam to rotate, on the one hand, the elliptic cam drives a brush to rotationally sweep the screen plate to promote seed dispersion, and on the other hand, two abutting plates are driven to move face to face and back to back alternately, sothat seed dispersion is greatly improved, and seed screening rate of the screen plate is remarkably increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a seed screening device for agricultural breeding. Background technique [0002] It refers to an important industrial sector in the national economy, which takes land resources as the production object, and it is an industry that produces food and industrial raw materials by cultivating animal and plant products. Agriculture is the primary industry. The sector that uses land resources for planting and production is the planting industry. The sector that uses the water space on the land for aquaculture is aquaculture, also known as fishery. The sector that uses land resources to cultivate and harvest forests is forestry, which uses land resources to cultivate or directly use grassland for development. Animal husbandry is animal husbandry. The small-scale processing or production of these products is a sideline, and they are an integral part of agriculture. The de...
