Description

Technical Field

[0001] The utility model belongs to the field of screening loquat tea leaves and relates to a device for screening loquat tea leaves. Background Technique

[0002] Loquat tea grows in the Qionglai Mountains at an altitude of 800 - 1400 meters within Chongzhou City, Sichuan Province. Loquat tea is a precious and rare tea tree variety in the country and is one of the five local improved tea tree varieties in Sichuan Province. It gets its name because the leaf shape resembles that of a loquat leaf. The large-leaf loquat tea in Wenjingjiang Town, Chongzhou City is the most precious and is the only original place of loquat tea. Since loquat tea leaves grow on relatively tall trees, they need to be picked manually with tools. During the picking process, some bark debris, branch debris, leaf debris, sediment, and dust are easily mixed into the loquat tea leaves. Therefore, it is necessary to screen out these impurities to obtain pure loquat tea leaves in the end. Currently, these impurities are screened manually, but the efficiency is low and a large amount of labor is required to complete it together. Currently, the method of air separation is used to screen loquat tea leaves, but the leaves separated by air separation are easily damaged.

[0022] The features and performance of the present utility model will be further described in detail below in conjunction with the embodiments.

[0023] Embodiment 1

[0024] The device of the present utility model for screening loquat tea, as Figure 1 shown, includes a horizontally arranged support base 1. Above the support base 1, there is a horizontally arranged screening trough 2. There is a space for screening loquat tea between the inner walls of the screening trough 2 and the upper end is open. A number of screening through-holes 3 for impurities to pass through are evenly distributed on the bottom of the inner walls of the screening trough 2. The outer walls at both ends of the screening trough 2 are respectively connected to the upper end surface of the support base 1 through a vibration promoting structure. Vibration structures are respectively connected to the outer walls on both sides of the screening trough 2, and the two vibration structures are symmetrical about the central axis of the screening trough 2.

[0025] The specific implementation manner of this embodiment is as follows: The screening trough is connected to the support base through a vibration promoting structure. The vibration promoting mechanism is used to connect the screening trough and at the same time promote the screening trough to vibrate. The vibration structures connected to both sides of the screening trough are used to drive the entire screening trough to vibrate. Pour the loquat tea to be screened into the interior of the screening trough, and then start the vibration structure to work. The vibration structure drives the entire screening trough to vibrate. During the vibration process, the loquat tea vibrates along with it, and during the vibration process, the impurities also vibrate. The purpose of the vibration is to make the impurities pass through the screening through-holes and leave the screening trough, while the loquat tea remains inside the screening trough. Through screening, the loquat tea is separated from the impurities. When the vibration generated by the vibration structure is transmitted to the vibration promoting structure, the entire screening trough is promoted to vibrate through the vibration promoting structure, making the entire screening trough vibrate more violently, and thus facilitating the full screening of the loquat tea.

[0026] Through the screening method set in this application, the impurities are separated from the loquat tea leaves while avoiding damage to the loquat tea leaves. At the same time, after pouring the loquat tea leaves to be screened into the screening tank, screening can be carried out. After screening, the loquat tea leaves can be taken out and then poured with the loquat tea leaves to be screened again, thereby making the screening efficiency of the loquat tea leaves relatively high.

[0027] Embodiment II

[0028] The device for screening loquat tea leaves of the present utility model is as Figure 1 shown. The vibration promoting structure includes a horizontally arranged support plate 4. One end of the support plate 4 is connected to the outer wall of the screening tank 2. A round steel spring 5 is provided between the support plate 4 and the support base 1. One end of the round steel spring 5 is connected to the lower end surface of the support plate 4, and the other end of the round steel spring 5 is connected to the upper end surface of the support base 1.

[0029] The vibration structure includes a vertically arranged vibration motor 6. The vibration motor 6 is connected to the outer wall of the screening tank 2 through a fixing seat 7.

[0030] The bottom of the screening tank 2 is connected with an inclined discharge hopper 8. The shape of the discharge hopper 8 matches the shape of the bottom of the screening tank 2. The size of the discharge hopper 8 is larger than the size of the bottom of the screening tank 2. The feed end of the discharge hopper 8 covers all the screening through holes 3 on the bottom of the screening tank 2, and the discharge end of the discharge hopper 8 is located above the support base 1.

[0031] The specific implementation method of this embodiment is that the support plate is used to connect the outside of the screening tank, and then the support plate and the support base are connected through a round steel spring. Through the round steel spring and the support plate, the whole screening tank is suspended, which is convenient for discharging the screened impurities. Setting the round steel spring is convenient for promoting the vibration of the screening tank and supporting the whole screening tank at the same time.

[0032] The vibration motor is connected to the outer wall of the screening tank through a fixing seat. During the operation of the vibration motor, the vibration is directly transmitted to the screening tank, thereby making the loquat tea leaves inside the screening tank vibrate.

[0033] The impurities that break away from the screening tank through the screening through holes enter the inside of the discharge hopper, and the impurities are collected through the discharge hopper, avoiding the problem of impurities scattering everywhere.

[0034] Embodiment III

[0035] The device for screening loquat tea leaves of the present utility model is as Figure 1 shown. A flipping structure is connected to the bottom of the screening tank 2. The flipping end of the flipping structure is located between the inner walls of the screening tank 2 and drives the loquat tea leaves to flip.

[0036] The flipping structure includes a driving motor 9 arranged vertically upward. The driving motor 9 is located outside the screening tank body 2. The outer wall of the driving motor 9 is connected to the bottom of the outer wall of the screening tank body 2 through a plurality of support columns 10. A driving shaft 11 is connected inside the driving motor 9. The upper end of the driving shaft 11 passes through the screening tank body 2 and is located between the inner walls of the screening tank body 2. At least one flipping blade 12 is connected to the outer wall of the upper end of the driving shaft 11.

[0037] A sealing bearing 13 is provided at the connection between the driving shaft 11 and the screening tank body 2. The outer ring of the sealing bearing 13 is connected to the screening tank body 2, and the inner ring of the sealing bearing 13 is connected to the outer wall of the driving shaft 11.

[0038] The specific implementation manner of this embodiment is as follows: The driving motor is connected to the bottom of the outer wall of the screening tank body through the support column. The driving motor is used to drive the driving shaft to rotate. The driving shaft drives the flipping blade to rotate. During the rotation of the flipping blade, the loquat tea leaves between the inner walls of the screening tank body are flipped, which further promotes the screening of the loquat tea leaves.

[0039] Preferably, the driving motor is started to work within a unit time, which avoids the flipping blade rotating continuously, and thus avoids the flipping blade affecting the impurities passing through the screening through-holes and separating from the screening tank body.

[0040] The sealing bearing provided at the connection between the driving shaft and the screening tank body is used to enable the driving shaft to be rotatably connected to the screening tank body, and at the same time, it avoids impurities entering the bearing interior.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, and improvements made by those skilled in the art within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
