Description

Technical field:

[0001] The invention relates to the field of agricultural machinery, in particular to a cottonseed shelling machine for cottonseed processing, in particular to a cottonseed cutting device integrating cutting, screening and automated processing. Background technology:

[0002] Cotton is one of the world's most important agricultural crops. Cottonseed, the seed of cotton, is a byproduct of the cotton industry and holds high economic value. Cottonseed is not only a source of oil, protein, and feed, but can also be processed and utilized as agricultural waste. However, the hardness of the cottonseed hull, which tightly wraps around the kernel, makes hulling a challenging process.

[0003] At present, cottonseed shelling is generally completed by mechanization. However, due to the large differences in cottonseed types and shapes, the following problems are prone to occur during the shelling process:

[0004] Hulling is difficult: Cottonseed hulls are hard and have strong adhesion, making traditional hulling methods often ineffective in removing them. In many cases, the hulling process requires extensive manual intervention, resulting in low efficiency and high labor intensity.

[0005] High cottonseed kernel breakage rate: Existing cottonseed shelling equipment easily damages the cottonseed kernels during the shelling process, affecting subsequent processing steps such as oil extraction. Due to the damage to the cottonseed kernels, the utilization value of the cottonseed kernels is greatly reduced, resulting in reduced economic benefits.

[0006] Inaccurate screening: After shelling, cottonseeds need to be screened to separate the hulls from the kernels. However, existing screening equipment often suffers from incomplete separation and low efficiency. This results in a high degree of mixing between the kernels and hulls, creating significant challenges for subsequent processing.

[0007] Low automation: Traditional cottonseed shelling equipment relies on simple mechanical drives or manual operation, resulting in a low level of automation and difficulty meeting the needs of large-scale cottonseed processing. Furthermore, existing equipment often lacks intelligent control, resulting in complex operation and low efficiency.

[0008] In summary, the existing cottonseed shelling technology has problems such as low efficiency, poor automation, poor shelling quality and limited processing capacity, especially in large-scale cotton processing, which cannot meet the growing production needs.

[0009] Therefore, a new type of cottonseed shelling machine is needed that can efficiently remove the cottonseed hulls while ensuring the integrity of the cottonseed kernels. It can also effectively separate the cottonseed kernels from the hulls through an efficient screening system. This not only improves shelling efficiency, but also reduces labor costs, reduces equipment failures, and improves the automation level of cottonseed processing, which is of great practical significance. Summary of the invention:

[0010] The present invention aims to provide a cottonseed shelling and screening machine that addresses existing issues such as low cottonseed cutting efficiency, inaccurate screening, and high manual intervention. By designing automated conveying, cutting, lifting, and screening systems, the present invention achieves efficient and precise cottonseed cutting and screening, significantly improving production efficiency and reducing manual intervention, making it suitable for large-scale cottonseed processing.

[0011] In order to achieve the above object, the present invention provides a cotton seed shelling and screening machine, the cotton seed shelling machine comprising:

[0012] a conveying device for conveying the cotton seed tray loaded with cotton seeds to the cutting device;

[0013] A cutting device, used for cutting cotton seeds by a cutting knife;

[0014] A lifting device is used to adjust the position of the cotton seed tray to a predetermined height, thereby ensuring that the cotton seeds can be evenly cut by the cutting knife;

[0015] The seed discharger is shaped like a funnel and can discharge cotton seeds evenly into the seed tray;

[0016] A transmission screen is used to screen the cut cotton seeds, remove the cottonseed shells, and transport the cottonseed kernels into a container;

[0017] The motor drive system is used to drive the above components to work together.

[0018] In this cottonseed shelling machine, the conveying device, cutting device, lifting device, seed discharger and transmission screen cooperate with each other to form an efficient and automated cottonseed processing system, which can realize the automated cutting, screening and discharge of cottonseeds, greatly improving work efficiency.

[0019] Specifically, the cutting device includes multiple adjustable cutting blades, which are adjusted to the appropriate position by a lifting mechanism to ensure that the cutting blades can accurately cut the cotton seeds without damaging them. The cut cotton seeds are then screened through a transmission screen, which effectively removes the cottonseed hulls and transfers the cottonseed kernels to a container.

[0020] The mesh of the transmission screen can adjust the size of the mesh holes as needed, thereby improving the screening accuracy and ensuring a more thorough separation of cottonseed kernels and cottonseed hulls.

[0021] In addition, the motor drive system uses a variable frequency motor or servo motor, which can adjust the working speed according to the specifications and cutting requirements of different cotton seeds to ensure the optimization of cutting effect and processing efficiency.

[0022] The cottonseed shelling machine of the present invention has the following significant advantages over the prior art:

[0023] High efficiency: The integrated design of automated conveying, cutting, screening, etc. greatly improves the efficiency of cottonseed processing and can meet the needs of large-scale production.

[0024] Accuracy: The precise design of the cutting device and transmission screen can ensure uniform cutting and accurate screening of cotton seeds, reduce the mixing of cotton seed kernels and cotton seed shells, and improve processing quality.

[0025] High degree of automation: The present invention adopts a motor drive system, and all components work together, which reduces manual intervention, reduces labor costs, and improves operational stability.

[0026] Wide range of applications: The cutting machine can be adjusted according to different types and specifications of cotton seeds. It has strong adaptability and is suitable for cotton seed processing enterprises of different sizes.

[0027] The present invention can significantly improve cottonseed processing efficiency, reduce manual intervention, and improve the accuracy during cottonseed processing, and has broad application prospects. Description of the drawings:

[0036] 1. Overview of the overall structure

[0037] The cottonseed shelling machine of the present invention mainly comprises a conveying device, a cutting device, a lifting device, a seed discharger, a transmission screen and a cotton seed tray. Through an automated control system, all components can work in coordination to achieve efficient cottonseed cutting, screening and discharge processes.

[0038] 2.Transmission device ( Figure 2 )

[0039] The transmission device is mainly composed of a transmission motor (11), a transmission belt (12), a transmission shaft (13), a bracket (14) and a transmission guide rail (15). The transmission motor (11) provides power to the system and transmits the power to the cotton seed tray (6) through the transmission belt (12) and the transmission shaft (13). The cotton seed tray (6) is provided with a guide wheel (61), which cooperates with the transmission guide rail (15) to ensure that the cotton seed tray (6) moves smoothly and accurately during the transmission process.

[0040] During the implementation process, the transmission motor (11) drives the transmission belt (12) to rotate according to the set speed, thereby driving the cotton seed tray (6) to move along the transmission guide rail (15). When the cotton seed tray (6) is delivered to the predetermined position, the conveying device stops working and prepares for the next cutting process.

[0041] 3. Cutting device ( Figure 4 )

[0042] The cutting device cuts the cotton seeds with a plurality of cutting knives (31). The cutting knives (31) are mounted on a bracket (32) and supported by a cutting device base plate (33). The shape, size and sharpness of the cutting knives are designed according to the properties of different cotton seeds to ensure uniform cutting effect without damaging the cotton seed kernels.

[0043] In actual operation, the cotton seed tray (6) is transported to the cutting device by the conveyor device, and the lifting device (see below for details) automatically adjusts the position of the cotton seed tray according to the set height, so that the cotton seeds are at the appropriate cutting height. The cutting knife (31) ensures that each cotton seed is cut evenly by rotating or reciprocating.

[0044] 4. Lifting device ( Figure 5 )

[0045] The lifting device is used to adjust the height of the cotton seed tray (6) to ensure that the cotton seeds can be cut at a suitable position. The lifting device includes a top plate (41), a bracket (42) and a lifting motor (43).

[0046] During the implementation process, when the conveying device delivers the cotton seed tray (6) to the cutting device, the lifting motor (43) is started to drive the lifting device to move up and down. By adjusting the height of the cotton seed tray, it is ensured that the cutting knife (31) can cut at a precise position and avoid errors and damage to the cotton seeds during the cutting process.

[0047] 5. Seed dispenser ( Figure 1 5)

[0048] The seed dispensing device is used to evenly discharge the cotton seeds onto the cotton seed tray (6). The seed dispensing device adopts a funnel-shaped structure and can be adjusted automatically or manually to ensure that the cotton seeds are evenly distributed before entering the cutting device.

[0049] The design of the seed discharger takes into account the fluidity and size differences of cotton seeds, and can maintain a stable discharge rate during the processing of various types of cotton seeds, thereby ensuring the uniformity of the cutting operation.

[0050] 6. Transmission screen ( Figure 3 )

[0051] The cut cotton seeds are screened through a transmission screen (2). The transmission screen comprises a screen (21), a protective cover (22), a vibration shaft (23), a bracket (24), a vibration motor (25) and a support frame (26).

[0052] The function of the transmission screen is to remove the outer shell of the cottonseed and separate the cottonseed kernel from the cottonseed shell. The vibration motor (25) drives the vibration shaft (23), generating vibration, so that the cottonseed can pass through the screen (21) for effective screening. The screen aperture can be adjusted according to the size of the cottonseed, thereby improving the screening accuracy. The screened cottonseed kernel is transported to a container through the outlet of the transmission screen.
