Technical Field
[0001] The utility model relates to the field of sap extraction devices, in particular to a handheld automatic sap extraction device. Background Art
[0002] In recent years, people have gradually paid more attention to the development and utilization of birch sap. Birch sap contains essential and easily absorbed carbohydrates, amino acids, organic acids and various inorganic salts. Natural birch sap is currently recognized as nutrient-rich physiologically active water in the world. The traditional birch sap collection process includes drilling, inserting tubes and collecting. The collector first selects a suitable birch tree, and uses a hand drill to diagonally drill a 4 to 6 cm deep hole upward toward the tree core at a height of 40 to 60 cm at the root of the birch tree. Then, a clean latex tube is inserted into the drill hole, and the other end of the latex tube is inserted into the collection bag, and the collection bag is tied to the tree to collect birch sap.
[0003] In order to facilitate the collection of birch sap, a handheld sap extraction device has been developed. The principle is that a motor drives a threaded rod to rotate, thereby driving a needle to move, and then the needle is inserted into the tree body to complete the extraction, which saves the collection steps and can be operated by hand, making it easy to use. However, the extraction device currently used still has the following technical problems in actual use: it is not convenient to observe the insertion depth of the needle after the needle is inserted into the tree, and it depends entirely on the experience of the operator, which may cause the needle to be inserted too deep or too shallow. If the needle is inserted too deep, it will damage the tree, and if it is inserted too shallow, the sap cannot be quickly extracted, which is inconvenient to use and has poor practicality.

DETAILED DESCRIPTION
[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:
[0022] like Figures 1 to 6 The handheld automatic juice extraction device shown in the figure comprises a contact plate 2 and an extraction needle 8, the contact plate 2 is connected to a mounting frame 1, the mounting frame 1 is rotatably connected to a first threaded rod 7 and a second threaded rod 14, the mounting frame 1 is connected to a servo motor 12, the output shaft of the servo motor 12 is connected to the first threaded rod 7, the extraction needle 8 is connected to a fixing plate 11, the fixing plate 11 is threadedly connected to the first threaded rod 7, the mounting frame 1 is connected to an auxiliary sliding rod 10, the fixing plate 11 is slidably connected to the auxiliary sliding rod 10, and the second threaded rod 14 is rotatably connected to the auxiliary sliding rod 10. The threaded rod 14 is threadedly connected with a positioning plate 15, and the positioning plate 15 is slidably connected to the auxiliary sliding rod 10. The mounting frame 1 is connected with a scale line 16, and the positioning plate 15 and the scale line 16 cooperate to read the value. The extraction needle 8 is provided with a liquid inlet hole 9, and a movable groove 18 is provided at the bottom of the mounting frame 1. The extraction needle 8 is connected with a suction tube 19, and the suction tube 19 can move along the movable groove 18. The suction tube 19 can be externally connected to a suction machine or a collecting bottle. The contact plate 2 and the mounting frame 1 are respectively provided with through holes 17, and the extraction needle 8 can pass through the through holes 17.
[0023] The contact plate 2 is connected to an adjusting device, which includes an adjusting plate 3. The adjusting plate 3 is rotatably connected to an adjusting threaded rod 5, which is threadedly connected to the contact plate 2. The adjusting plate 3 is connected to a sliding rod 6, which is slidably connected to the contact plate 2. The adjusting device is provided with two groups, which are respectively located on the upper and lower sides of the contact plate 2.
[0024] The mounting frame 1 is connected with a gripping handle 13 , the inner wall of the liquid inlet hole 9 is connected with a filter screen plate 20 , and the adjusting plate 3 is connected with a protective rubber pad 4 .
[0025] The first threaded rod 7 is driven to rotate by the servo motor 12, and the auxiliary slide bar 10 limits the rotation of the fixed plate 11. Therefore, as the first threaded rod 7 rotates, the fixed plate 11 moves leftward or rightward along the first threaded rod 7, thereby driving the extraction needle 8 to move.
[0026] Similarly, when the second threaded rod 14 is rotated, the auxiliary sliding rod 10 limits the rotation of the positioning plate 15. Therefore, as the second threaded rod 14 rotates, the positioning plate 15 moves left or right along the second threaded rod 14, and the positioning plate 15 is located on the left side of the fixing plate 11. When the positioning plate 15 is fixed, the fixing plate 11 moves leftward and drives the extraction needle 8 to move leftward and insert into the tree. When the fixing plate 11 contacts the positioning plate 15, the fixing plate 11 cannot continue to move leftward, thereby completing the control of the insertion depth of the extraction needle 8.
[0027] By turning the adjusting threaded rod 5, since the adjusting threaded rod 5 is rotationally connected to the adjusting plate 3, and the adjusting threaded rod 5 is connected to the threaded rod of the abutment plate 2, and the sliding rod 6 is slidingly connected to the abutment plate 2, the adjusting plate 3 can move left or right relative to the abutment plate 2 as the adjusting threaded rod 5 rotates.
[0028] The specific implementation process is as follows:
[0029] When in use, the adjusting threaded rod 5 is screwed to adjust the position of the corresponding adjusting plate 3, so that the adjusting plate 3 contacts the tree, and the two adjusting plates 3 contact the upper and lower sides of the tree sampling point respectively. By adjusting the distance between the two adjusting plates 3 and the contacting plate 2, an angle is formed between the mounting frame 1 and the tree after the adjusting plates 3 contact the tree, thereby adjusting the insertion angle of the extraction needle 8. The angle adjustment can be completed by adjusting several times. In this way, the setting can adapt to trees with different upper and lower end diameters and curved growth; before adjusting the adjusting plate 3, the second threaded rod 14 can be screwed to adjust The positioning plate 15 is positioned and adjusted to a suitable position in conjunction with the scale line 16. After the angle of the adjusting plate 3 is adjusted, the adjusting plate 3 is pressed against the tree. Then the servo motor 12 is started. The servo motor 12 drives the first threaded rod 7 to rotate and then drives the extraction needle 8 to move left. The extraction needle 8 passes through the through hole 17 and is inserted into the tree. When the fixing plate 11 contacts the positioning plate 15, the extraction needle 8 cannot be inserted any further. Then the servo motor 12 is turned off, and the juice can enter the extraction tube through the liquid inlet hole 9 and then be discharged from the suction tube 19 into the collection container.
[0030] The technical solution drives the first threaded rod 7 to rotate and drives the extraction needle 8 to move to complete sampling through the servo motor 12. At the same time, the insertion depth of the extraction needle 8 is controlled through the cooperation of the positioning plate 15 and the fixing plate 11, so that the insertion depth of the extraction needle 8 can be controlled. The position of the positioning plate 15 can be quickly adjusted through the second threaded rod 14, and the position of the positioning plate 15 can be quickly and accurately adjusted through the scale line 16, so as to accurately adjust the insertion depth of the extraction needle 8, so as to avoid the situation that the extraction needle 8 is inserted too deep or too shallow, improve the efficiency and quality of liquid collection, protect the safety of trees, have a simple structure, are easy to operate, and are greatly practical. The adjustment device can adjust the position of the adjustment plate 3 by twisting the adjustment threaded rod 5. The different positions of the two groups of adjustment plates 3 can make the needle inserted into the tree body at different angles. The insertion angle can be adjusted by placing the two groups of adjustment plates 3, which makes the adjustment more convenient. The two groups of adjustment plates 3 respectively contact the trees on the upper and lower sides of the sampling position, which can adapt to trees with different bending degrees, improve the adjustment accuracy, and facilitate the subsequent pressing of the contact plate 2 for use; the gripping handle 13 is convenient for the operator to hold and use; the filter screen plate 20 prevents wood chips from entering the extraction needle 8, and the protective rubber pad 4 can protect the tree to avoid scratching the bark when the extraction needle 8 is inserted.
