Description

Technical Field

[0001] The utility model relates to the field of tea production and processing equipment, in particular to a rotary tea spreading machine. Background Art

[0002] There are many types of tea, but the processing steps of different teas generally include fresh leaf picking, killing green, withering, rolling, fermentation and drying.

[0003] In the tea processing steps, it is often necessary to spread the tea leaves evenly on a bamboo plate. In the prior art, this spreading process is generally done manually, which has low work efficiency and is prone to uneven spreading (the automatic tea spreading machine with application number 202322344240.0 also mentions this technical problem in the background technology). The purpose of the utility model is to propose a new device to solve the above technical problems and improve the work efficiency in the tea processing process. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a machine base, a column, a hopper, a shovel plate and a dust box, a rotating motor is fixedly installed on the machine base, the rotating motor shaft is connected to the grab arm, the column is fixed on one side of the machine base, a rotary motor is fixedly installed on the column and the rotary motor shaft is connected to the rotary arm, the hopper is installed at one end of the rotary arm, a discharge port is formed at the bottom of the hopper, the shovel plate is obliquely installed on one side of the hopper adjacent to the discharge port, the dust box is connected to the other end of the rotary arm through an extension arm, a connecting pipe for connecting to an external dust suction device is formed on the top of the dust box, dust suction pipes are arranged at equal intervals on the bottom of the dust box, the dust suction pipes are connected to the dust box and the distance between the dust suction pipes can allow tea leaves to pass through.

[0006] In order to optimize the above technical solution, further measures are taken: the bottom end of the dust suction tube is in the shape of an inverted truncated cone, a through hole is formed in the center of the dust suction tube, and the truncated cone structure can form a surplus in the circumferential direction of the bottom end of the dust suction tube for separating tea leaves from tea debris.

[0007] As a further improvement of the above technical solution: a limiting rod is formed on the side of the bottom end of the vacuum tube, the limiting rod is distributed in a ring shape and surrounds the through hole, and tea leaves cannot pass through the spacing of the limiting rods. The purpose of setting the limiting rod is to block tea leaves and prevent tea leaves from clogging the through hole and preventing tea debris from passing through.

[0008] As a further improvement of the technical solution: the length of the grab arm is variable, so that the grab arm can be suitable for bamboo plaques of different sizes.

[0009] As an improvement on the above technical solution: the grab arm consists of a fixed end, a movable end and a spring. The fixed end is connected to the rotating shaft of the rotating motor. The movable end and the fixed end constitute a moving pair along the length direction of the grab arm. The two ends of the spring are respectively connected to the fixed end and the movable end. The spring drives the movable end to tighten the bamboo plaque to reduce the shaking of the bamboo plaque during the tea sprinkling process.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a rotary tea spreading machine, which realizes automatic feeding through the cooperation of a hopper and a rotating bamboo plate, and then uses a shovel plate to flatten the tea leaves, and uses vacuum tubes arranged at intervals to spread the tea leaves, so that the tea leaves are evenly dispersed on the bamboo plate. During the process, tea leaves crumbs will also be sucked into the vacuum tube, which helps to ensure the improvement of the quality of the tea leaves and reduce the subsequent cleaning work of the tea leaves crumbs.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-4 The utility model provides a rotary tea spreading machine, including a machine base 1, a column 2, a hopper 3, a shovel plate 4 and a dust box 5. A rotary motor 101 is fixedly installed on the machine base 1. The rotating shaft of the rotary motor 101 is connected to a grab arm 102. The grab arm 102 has a variable length. The grab arm 102 is composed of a fixed end 103, a movable end 104 and a spring 105. The fixed end 103 is connected to the rotating shaft of the rotary motor 101. The movable end 104 and the fixed end 103 form a moving pair along the length direction of the grab arm 102. The two ends of the spring 105 are respectively connected to the fixed end 103 and the movable end 104.

[0021] The column 2 is fixed on one side of the machine base 1 , a rotary motor 201 is fixedly mounted on the column 2 , and the rotary shaft of the rotary motor 201 is connected to the rotary arm 202 , so that the rotary arm 202 is driven to rotate by the rotary motor 201 .

[0022] The hopper 3 is installed at one end of the rotating arm 202 , and a discharge port 301 is formed at the bottom of the hopper 3 . An opening and closing device for controlling the flow of the discharge port 301 is provided at the discharge port 301 , and tea leaves can be scattered on the bamboo plate from the discharge port 301 .

[0023] The shovel plate 4 is obliquely installed at one side of the hopper 3 adjacent to the discharge port 301, and the shovel plate 4 is used to flatten the tea leaves to prevent a large amount of tea leaves from piling up.

[0024] The dust box 5 is connected to the other end of the rotating arm 202 through an extension arm 501, and a connecting pipe 502 for connecting to an external dust suction device is formed at the top of the dust box 5. Dust suction pipes 503 are arranged at equal intervals on the bottom surface of the dust box 5. The dust suction pipes 503 are connected to the dust box 5 and the distance between the dust suction pipes 503 is enough for tea leaves to pass through. The bottom end of the dust suction pipe 503 is in an inverted frustum shape, and a through hole 504 is formed in the center of the dust suction pipe 503. A limiting rod 505 is formed on the side surface of the bottom end of the dust suction pipe 503, and the limiting rods 505 are distributed in a ring shape to surround the through hole 504. The distance between the limiting rods 505 is such that tea leaves cannot pass through.

[0025] The control method of the present invention is to realize automatic control through an external controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0026] Working principle: the tea tray is placed on the gripping arm 102 and the spring 105 drives the movable end 104 to clamp the bamboo tray. The tea tray will rotate on the machine base 1 under the drive of the rotating motor 101. During the process, the tea leaves fall from the discharge port 301 and are evenly scattered on the rotating tea tray. At the same time, the shovel plate 4 can flatten the tea leaves during the rotation of the bamboo tray to avoid tea leaves from stacking.

[0027] Then the rotary motor 201 drives the rotary arm 202 to rotate, and the hopper 3 is driven by the rotary arm 202 to move away from the tea plaque, and the dust box 5 will move above the tea plaque. As the tea plaque rotates, the dust suction pipes 503 arranged at equal intervals can flatten the tea leaves flattened by the shovel plate 4. During the process, the tea leaves will be sucked away by the through holes 504 to ensure uniform quality of the tea leaves.

[0028] When the vacuum tube 503 is used to flatten the tea leaves, the limiting rod 505 can block the tea leaves, and cooperate with the frustum structure at the bottom end of the vacuum tube 503 to form a gap on the side of the bottom end of the vacuum tube 503 to block the tea leaves and separate the tea leaves from the tea residue, thereby preventing the tea leaves from clogging the through hole 504 and affecting the collection of tea debris by the vacuum tube 503.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
