Description

Technical Field

[0001] This utility model relates to the technical field of tea grading machines, specifically a tea grading machine with a stem-removing device. Background Technology

[0002] During the tea production process, tea leaves need to be sorted, mainly based on their size. Larger tea leaves have a stronger flavor, but require a longer processing time and higher processing costs. Processing tea leaves separately can effectively reduce processing costs.

[0003] According to Chinese Patent Publication No. CN211865800U, a tea filter machine includes a body. The upper surface of the body is open and inclined, as is the bottom surface. The inclined surface of the upper surface slopes downwards in a backward-forward direction, while the inclined surface of the bottom slopes upwards in a backward-forward direction. The rear sidewall of the body is open. Limiting strips are installed on the left and right sides of the upper surface of the body. The front end face of the limiting strip is in the same plane as the front sidewall of the body, and the rear end face of the limiting strip is in the same plane as the rear sidewall of the body. Long, narrow grooves are formed on the opposite surfaces of the two limiting strips, and these grooves are parallel to the upper surface of the body. A filter plate is slidably connected between the two grooves of the two limiting strips. The filter plate has several arrayed filter holes, and spring mounting blocks are formed at the four corners of the upper surface of the filter plate.

[0004] However, while this device can filter out dust and impurities mixed on the surface of tea leaves, it cannot grade and sort them according to the size of the tea leaves. In the existing technology, the tea leaves usually need to be filtered multiple times, which takes a lot of time and reduces the efficiency of tea processing. Therefore, a tea grading machine with a stem-removing device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tea grading machine with a stem-picking device, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A tea grading machine with a stem-removing device includes a back plate, and a grading and filtering mechanism is provided on the front of the back plate.

[0008] The graded filtration mechanism includes two first support rods, a first slide rod, two second support rods, a second slide rod, two movable plates, a first filter plate, and a second filter plate;

[0009] The first support rod is fixedly connected to the front of the back plate. The left and right ends of the first sliding rod are respectively fixedly connected to two first support rods. The second support rod is located at the bottom of the first support rod, and the left and right ends of the second sliding rod are respectively fixedly connected to two second support rods. A transverse groove is formed through the left side of the movable plate, and a linear bearing is fixedly connected inside the groove. The first and second sliding rods slide through the movable plate via the linear bearing. The first and second filter plates are fixedly connected to the front of the two movable plates. The first filter plate is located on top of the second filter plate, and the first filter plate is inclined with a left-higher-right-lower orientation. The second filter plate is also inclined with a left-lower-right-higher orientation. The diameter of the filter holes on the first filter plate is larger than the diameter of the filter holes on the second filter plate. The left and right movement of the first and second filter plates is limited by the first and second sliding rods.

[0010] Preferably, a vibration mechanism is provided on the front of the back plate. The vibration mechanism includes two third support rods, which are fixedly connected to the front of the back plate. A third sliding rod is fixedly connected between the two third support rods. Striking balls are fixedly connected to the left and right ends of the third sliding rod, and the two striking balls are respectively fixedly connected to the two movable plates. The left and right movement of the third sliding rod is limited by the third support rods.

[0011] Preferably, a first movable rod is rotatably connected to the front of the back plate via a pivot, and the top end of the first movable rod is hinged to the middle of a third sliding rod via a second movable rod. The pivot provides support for the first movable rod.

[0012] Preferably, a motor is fixedly connected to the back of the back plate, and the front output end of the motor extends through to the front end of the back plate and is fixedly connected to a drive shaft via a coupling. A third movable rod is fixedly connected to the front end of the drive shaft. A sliding groove is formed through the front of the first movable rod, and a slider is slidably connected inside the sliding groove. The slider is fixedly connected to the other end of the third movable rod away from the drive shaft. The movement of the slider is limited by the sliding groove.

[0013] Preferably, a base is fixedly connected to the bottom of the back plate, and a first collection box, a second collection box, and a third collection box are fixedly connected to the top of the base. The first collection box is located at the lower right corner of the first filter plate, the second collection box is located at the lower left corner of the second filter plate, and the third collection box is located at the bottom of the second filter plate.

[0014] Preferably, a fan is mounted on the back plate via a mounting bracket, and the fan is positioned on the front of the first filter plate.

[0015] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0016] 1. By turning on the motor, the drive shaft rotates, causing the first and second filter plates to move left and right, and shaking and sifting the tea leaves. Larger tea leaves will roll off the first filter plate into the first collection box, while smaller tea leaves will fall through the filter holes on the first filter plate and onto the second filter plate. Subsequently, the smaller tea leaves will roll off the second filter plate into the second collection box, thus quickly completing the grading and sorting of tea leaves and improving the processing efficiency of tea.

[0017] 2. Broken tea stems will fall through the filter holes on the second filter plate and into the third collection box. During the shaking and sifting process of the tea leaves on the first and second filter plates, the electric fan is turned on. The electric fan generates wind forward to blow away the dust and broken leaves attached to the surface of the tea leaves. This can remove the impurities mixed inside the tea leaves while grading and sorting the tea leaves, thus improving the quality of the finished tea. Attached Figure Description

The first filter plate 26 and the second filter plate 27 are fixedly connected to the front of the two movable plates 25. The first filter plate 26 is located on top of the second filter plate 27. The first filter plate 26 is inclined with the left side higher than the right side. The second filter plate 27 is inclined with the left side lower than the right side. The diameter of the filter holes on the first filter plate 26 is larger than the diameter of the filter holes on the second filter plate 27.

[0030] The first slide bar 22 and the second slide bar 24 are used to limit the left and right movement of the first filter plate 26 and the second filter plate 27.

[0031] The front of the back plate 1 is provided with a vibration mechanism 3. The vibration mechanism 3 includes two third support rods 31. The third support rods 31 are fixedly connected to the front of the back plate 1. A third slide rod 32 is fixedly connected between the two third support rods 31.
