Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a device for dehydrating and drying mulberry leaves after rinsing. Background Technology

[0002] Mulberry leaves used in silkworm breeding farms are primarily for silkworm egg production, thus requiring high quality. Harvested from the mulberry tree, the leaves often contain insects, eggs, and other debris, necessitating washing and spin-drying before use. Therefore, a mulberry leaf washing, dehydration, and spin-drying device for silkworm breeding farms is needed. However, after washing, the leaves tend to stick together when wet, making direct spin-drying difficult and resulting in low efficiency. Furthermore, the array of drainage channels on the surface of the spin-drying cylinder hinders the accumulation of hot airflow, leading to significant heat waste.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

The receiving cylinder contains a propeller blade. The spinning drum is driven to rotate by a motor. Both the spinning drum and the receiving cylinder are arranged at an angle and axially overlap, and are closely connected by a connecting seat. An air inlet groove is provided on the receiving cylinder. A hollow sealing sleeve is fitted around the outer periphery of the receiving cylinder, its internal space covering the outer wall of the spinning drum. A connecting groove is provided on one side of the sealing sleeve to introduce external hot airflow.

[0015] (III) Beneficial Effects

[0016] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The mulberry leaf washing and dehydration device of this utility model has a receiving cylinder on the coaxial front side of the spinning drum, which allows the excess hot air in the spinning drum to flow into the receiving cylinder for preheating. During the process of the propeller blades rotating relatively slowly to conduct the mulberry leaves to the spinning drum, the wet and sticky mulberry leaves are separated as much as possible and preheated. At the same time, a sealing sleeve is provided on the outside of the spinning drum, and a spiral groove is opened on the outer wall, so that a stable vortex field is formed inside the cylinder, thereby more effectively drawing in external hot air.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-3 The image shows a mulberry leaf rinsing and dehydration device, comprising a base, on which a spin-drying cylinder and a receiving cylinder are inclinedly arranged via a second support and a first support, respectively. Rotating bushings are provided on both sides of the receiving cylinder, and guide wheels are provided on both sides of the first support, allowing the receiving cylinder to be rotatably connected to the first support. The spin-drying cylinder is fixed to the second support. A connecting seat is fixed to the end of the receiving cylinder, extending to be adjacent to (closely adjacent to, with a slight gap) the spin-drying cylinder, allowing the two to connect and communicate.

[0024] The tilt angles of the swiping drum and the receiving drum should not be too large; they should be just enough to smoothly transfer the mulberry leaves from the receiving drum to the swiping drum.

[0025] A hollow sealing sleeve is fitted around the outer periphery of the accommodating cylinder. Its internal space covers the outer wall of the slinger and can be supported on the base by a connecting rod. A small circumferential gap is left between the two ends of the sealing sleeve and the slinger. A connecting groove is opened on one side below it to connect to the air pipe for introducing hot air from the outside.

[0026] As attached Figure 4 As shown, the outer surface of the container cylinder has spiral grooves that lead into the interior, and the entire spiral groove is within the coverage area of ​​the sealing sleeve. The spiral grooves guide the airflow into the cylinder along the spiral direction, enabling the airflow to rotate and increasing the air intake area on the cylinder surface, allowing the airflow to enter the cylinder more evenly. This rotational motion helps to form a stable vortex field inside the cylinder, thereby more effectively drawing in external hot air.

[0027] A motor is mounted on the base, and the output end of the motor is connected to a large gear via a coupling. A small gear seat that meshes with the large gear is fitted onto the corresponding position of the receiving cylinder, enabling the receiving cylinder to rotate. Next, a large gear seat is fitted onto the spinning drum, with a coupling extending to the bottom of the spinning drum and connecting to a small gear, which meshes with the large gear.

[0028] It should be noted that the spinning drum does not rotate. The large gear is fixedly connected to the propeller blade in the middle of the spinning drum via a support rod on the inner periphery of the spinning drum (specifically connected to the end of the rotor of the propeller blade). Through the transmission design between the gears, the propeller blade is driven by the large gear seat at a significantly slower speed (that is, through the difference in size between the gears and the improvement of the transmission method, the rotation process of the propeller blade is slower. Of course, the rotation speed can also be the same, but it is best to be able to transmit at a slower speed). This slows down the progress of the mulberry leaves being driven inward, so as to fully realize the preheating and stirring of the mulberry leaves.

[0029] Since the mulberry leaves are pre-loaded into the spinning drum, a groove needs to be opened at the bottom of the drum to allow the dripping mulberry leaves to flow out in advance.

[0030] Secondly, the motor is installed at an angle and parallel to both the throwing drum and the receiving drum, which enables the transmission of driving force.

[0031] The inside of the swirl drum is equipped with a propeller blade for stirring and transporting mulberry leaves. The propeller blade has an axially through array of air holes, which allows the hot airflow entering from the container to be transferred to the container, thus preheating the mulberry leaves inside.

[0032] Furthermore, a baffle is provided circumferentially inside the container. The baffle extends inward, which helps the mulberry leaves to be distributed relatively evenly along the inner wall of the container, and prevents the mulberry leaves from accumulating at the bottom of the container during rotation.

[0033] The container has a flip-top on the bottom, which can be opened to remove the dried mulberry leaves.

[0034] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
