Abstract
Description
Technical Field
[0001] This utility model relates to the field of small-scale agricultural processing equipment technology, and in particular to an auxiliary hulling device for cotton seeds of small quantities of cotton germplasm resources. Background Technology
[0002] Cottonseed is an important oilseed and feed ingredient, but its husk is hard and tough, making hulling a crucial preliminary step for determining the oil and protein content of the cotton kernels. Mechanical hulling is suitable for industrial or large-scale processing, but small-batch, high-frequency hulling needs in farming or research typically rely on hand hulling or simple tools for beating, which is inefficient, with each person only able to process 5-10 kg per day, and long-term operation can easily lead to hand fatigue and cuts. This auxiliary device is simple to operate and requires no complicated training. Summary of the Invention
[0003] The purpose of this invention is to provide a cottonseed hulling auxiliary device that is simple to operate, has low maintenance costs, is user-friendly for non-professional operators, and can greatly improve the hulling efficiency in small-scale production, scientific research and other scenarios, which is needed for assisting in the hulling of small quantities of cottonseed.
[0004] This utility model discloses an auxiliary hulling device for cotton seeds suitable for small-scale cotton germplasm resources. Its structure includes a cotton seed disc, a functional disc, and a cutting disc. The lower surface of the functional disc has a circular groove I, and the cutting disc is embedded in the circular groove I of the functional disc. A motor is located above the functional disc, and the motor can drive the cutting disc to rotate horizontally within the circular groove I of the functional disc via a transmission shaft. The cotton seed disc is located below the functional disc, and its upper surface has a circular groove II for placing cotton seeds. A connecting screw is provided on one side of the cotton seed disc, and one side of the functional disc is threadedly connected to the connecting screw. One side of the functional disc can move up and down along the connecting screw and is fixed by an adjusting nut. When the functional disc moves downward and engages with the cotton seed disc, the cutting disc can extend downward into the circular groove II of the cotton seed disc.
[0005] Preferably, the motor drive shaft passes through the function disk and is fixedly connected to the cutting disk below it, and the motor drive shaft and the function disk are connected by bearings.
[0006] Preferably, the lower surface of the cutting disc is provided with multiple cutting rings, i.e. multiple concentric annular convex patterns.
[0007] Preferably, the inner surface of the circular groove II of the cottonseed disc is a plane, or is provided with multiple concentric annular convex lines at intervals, or is provided with multiple convex lines radiating outward from the center at intervals, or is provided with multiple convex lines parallel to the diameter at intervals.
[0008] Preferably, the cottonseed disc has an extension handle I on one side, a connecting screw is provided on the extension handle I, and the functional disc has an extension handle II on one side. The extension handle II is threadedly connected to the connecting screw, and an adjusting nut is provided above the extension handle II.
[0009] The working principle of this invention is as follows: The device mainly consists of three parts: a cottonseed disc, a functional disc, and a cutting disc, connected by a connecting screw. The cottonseed disc (lower disc) is fixed and has a concave design, serving as a support surface for hulling. The functional disc (upper disc) can be moved vertically via the screws on the connecting screw, and its gap with the cottonseed disc can be adjusted to match the cottonseed particle size. A horizontally rotatable cutting disc is nested inside the functional disc, with N concentric cutting rings on the side in contact with the cottonseed disc. When cottonseeds are placed inside the cottonseed disc, the rotating cutting rings on the cutting disc directly act on the cottonseed shells, causing the shells to break and separate.
[0010] Compared with the prior art, the advantages of this utility model are: it aims to solve the problem of insufficient adaptability to large equipment, and provides a simple, low-maintenance, and user-friendly auxiliary cottonseed shelling device for small-scale cotton germplasm resources. It is suitable for non-professional operators and can greatly improve the shelling efficiency and convenience of auxiliary cottonseed shelling in small-scale production, scientific research and other scenarios.
