Description

Technical Field

[0001] This utility model relates to a seed sorting machine for crops, specifically a seed sorting machine for crops, and belongs to the field of crop seed screening technology. Background Technology

[0002] A seed sorting machine is a device used to select high-quality crop seeds. It aims to select seeds with excellent biological characteristics to improve seed germination rate and crop yield. During the seed sorting process, the seeds rotate along the spiral groove. Under the action of centrifugal force, the denser stones, the less dense inferior seeds, and the moderately dense high-quality seeds are separated.

[0003] When using a seed separator to screen crop seeds, some seeds may stick together with moist soil, leaves, or other seeds. These sticky mixtures are prone to incorrect screening due to their large volume and weight, which affects the accuracy of crop seed screening and causes some seeds to be wasted.

Under the transmission action of the first sprocket, the second sprocket and the chain, the motor can drive the first rotating rod and the second rotating rod to rotate synchronously when it is running.

[0008] Furthermore, two fixing blocks are fixedly connected to the outer surface of the fixed bucket, and springs are fixedly connected to the upper surface of the two fixing blocks. The top ends of the two springs are fixedly connected to the outer surface of the screening cylinder. The springs are always in a compressed state, and under the elastic force of the springs, the wear-resistant blocks can be tightly attached to the cam roller.

[0009] Furthermore, telescopic rods are fixedly connected to the upper surfaces of both fixed blocks, and the top ends of both telescopic rods are fixedly connected to the outer surface of the screening cylinder. The telescopic rods guide the movement of the screening cylinder.

A conical hopper is fixedly connected to the top of the fixed column. The conical hopper is adapted to the fixed hopper. The discharge port of the fixed hopper is located directly above the conical hopper, so that the crop seeds in the fixed hopper fall into the conical hopper.

[0012] Specifically, the outer surface of the fixed column is fixedly connected with a first spiral groove, a second spiral groove and a third spiral groove. The first spiral groove, the second spiral groove and the third spiral groove are all adapted to the conical hopper. The first spiral groove, the second spiral groove and the third spiral groove are all provided with discharge pipes so that the substances selected by the first spiral groove, the second spiral groove and the third spiral groove are separated.

This facilitates more accurate screw sorting of the seeds in the subsequent process, avoids the waste caused by directly removing these adhering mixtures during screw sorting, and improves the accuracy of seed screw sorting.

[0015] This crop seed screw separator uses a screw separator assembly to separate crop seeds after they have been broken up and dried. The seeds fall into a conical hopper and pass through a first, second, and third spiral groove. During the rotation process, under the action of centrifugal force, the denser stones enter the third spiral groove, while the less dense soil and substandard seeds remain in the first spiral groove. This process separates the denser stones, less dense soil, and substandard seeds from the high-quality seeds, allowing the high-quality seeds to be collected. Attached Figure Description

Under the transmission action of the first sprocket 215, the second sprocket 216 and the chain, the motor 214 can drive the first rotating rod 27 and the second rotating rod 29 to rotate synchronously when it is running.

[0030] Two fixing blocks 217 are fixedly connected to the outer surface of the fixed bucket 23. Springs 218 are fixedly connected to the upper surface of the two fixing blocks 217. The tops of the two springs 218 are fixedly connected to the outer surface of the screening cylinder 212. The springs 218 are always in a compressed state. Under the elastic force of the springs 218, the wear-resistant block 213 can be tightly attached to the cam roller 210.

[0033] Please refer to this carefully. Figure 1 and Figure 5 A screw separator assembly 3 is provided above the base 1. The screw separator assembly 3 includes a fixed column 31 fixedly connected to the upper surface of the base 1. A conical hopper 32 is fixedly connected to the top of the fixed column 31. The conical hopper 32 is adapted to the fixed hopper 23. The discharge port of the fixed hopper 23 is located directly above the conical hopper 32, so that the crop seeds in the fixed hopper 23 fall into the conical hopper 32.

[0034] The outer surface of the fixed column 31 is fixedly connected with a first spiral groove 33, a second spiral groove 34 and a third spiral groove 35. The first spiral groove 33, the second spiral groove 34 and the third spiral groove 35 are all adapted to the conical bucket 32. The first spiral groove 33, the second spiral groove 34 and the third spiral groove 35 are all provided with discharge pipes to separate the materials selected by the first spiral groove 33, the second spiral groove 34 and the third spiral groove 35.

[0035] Working principle: Crop seeds are added to the feed hopper 22 and fall into the separation hopper 21. The hot air blower 24 and motor 214 are controlled to operate. The hot air blower 24 blows hot air into the separation hopper 21, drying the seeds and the moisture adhering to their surface, such as soil, leaves, or other seed surfaces. Simultaneously, the motor 214 drives the first rotating rod 27 and the dispersing plate 28 to rotate, dispersing the seeds and their adhering substances. The seeds then enter the screening cylinder 212 through the connecting hose 211. Under the rotation of the second rotating rod 29 and the cam roller 210, and the elastic force of the spring 218, the screening cylinder 212 is pressed tightly against the surface of the cam roller 210, causing it to reciprocate. The screening cylinder 212... Seeds are screened so that small-volume seeds, soil, and pebbles fall into a fixed hopper 23, while large-volume branches, leaves, and pebbles are removed. Seeds in the fixed hopper 23 fall into a conical hopper 32. The seeds first enter the first spiral groove 33 for rotating descent. During the rotation and under the action of centrifugal force, the denser pebbles enter the third spiral groove 35, while the less dense soil and substandard seeds remain in the first spiral groove 33. This separates the denser pebbles, less dense soil, and substandard seeds from the high-quality seeds, and collects the high-quality seeds. This device can break up, dry, and separate the seeds from the moist soil, branches, leaves, or other seeds adhering to their surface, thus facilitating more precise seed selection in the subsequent spiral process.
