Description

Technical Field

[0001] The utility model relates to the technical field of sap collection, in particular to a birch sap collection device. Background Art

[0002] Birch sap is the juice flowing from natural birch trees. It is a colorless or slightly yellow transparent liquid. According to tests, birch sap contains 17 trace elements such as potassium, calcium, phosphorus, iron, sodium, zinc, and more than 10 amino acids and fatty acids. In addition, it also contains a variety of vitamins. These ingredients are easily absorbed by the human body and have a positive effect on promoting the normal activities and metabolism of human life.

[0003] The sap is generally collected by a more traditional method. First, an electric drill is used to drill a hole in the tree trunk at an angle of 15-20°, with a depth of about 10-15 cm. A short tube is inserted into the hole, and the end of the short tube leaks out of the trunk. The short tube draws the sap out and drips it into a collection bag or a collection bucket. The disadvantage of using a short tube for drainage collection is that the inner diameter of the hole is generally slightly larger than the outer diameter of the short tube when drilling, and the sap is easy to flow out from the gap between the short tube and the inner wall of the hole, resulting in a waste of sap. In addition, due to the long collection time, external dust, mud, grass and other impurities will enter the hole along the gap between the short tube and the inner wall of the hole under the action of wind, causing contamination of the drained sap.

[0004] Therefore, it is necessary to provide a birch sap collecting device to solve the above-mentioned technical problems. Utility Model Content

The neck portion 7 at the liquid inlet of the collection bag 6 is screwed into the joint sleeve 4 through threaded cooperation, so that the interior of the collection tube 3 and the interior of the collection bag 6 are connected. When the birch sap is drained, the sap in the trunk will enter the collection tube 3 and flow out into the collection bag 6 for collection, so as to collect the birch sap.

[0023] Further Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the sealing assembly 1 includes a rubber tube 101 arranged at one end of the collection tube 3, the rubber tube 101 is fitted and fixed on the outer wall of the collection tube 3, a first inner cavity 102 is opened in the rubber tube 101, an infusion tube 103 connected to the first inner cavity 102 is fixed on the outer wall of the end of the rubber tube 101 close to the joint sleeve 4, a middle sleeve 104 located between the joint sleeve 4 and the rubber tube 101 is fixed on the outer wall of the joint sleeve 4, a second cavity 105 is arranged inside the middle sleeve 104, and the inner wall of the second cavity 105 is tightly fitted with The annular piston plate 106, the rotary push assembly 2 includes a connecting rod 201 fixed to the side of the annular piston plate 106, and the connecting rod 201 is provided with multiple and the multiple connecting rods 201 are distributed in an annular shape. The ends of the multiple connecting rods 201 away from the annular piston plate 106 are commonly fixed with an outer sleeve 202, and the outer sleeve 202 is threadedly connected to the outer wall of the collection tube 3; first, a hole is drilled in the tree trunk, the size of the hole is slightly larger than the outer diameter of the rubber tube 101, and at this time, there is a certain gap between the outer wall of the rubber tube 101 and the inner wall of the hole, so that the rubber tube 101 on the collection tube 3 can be easily inserted. One end is inserted into the hole, and the outer sleeve 202 is held by hand and rotated to make the outer sleeve 202 approach the rubber tube 101, and the outer sleeve 202 simultaneously drives the connecting rod 201 to rotate, thereby driving the annular piston plate 106 to rotate inside the middle sleeve 104 through the connecting rod 201, and the second cavity 105 is filled with a certain amount of liquid, which can be water or hydraulic oil, and then the annular piston plate 106 transports the liquid inside the middle sleeve 104 to the first inner cavity 102 through the infusion tube 103, so that The rubber tube 101 is expanded so that the side wall of the rubber tube 101 is tightly attached to the inner wall of the hole, thereby fully filling and sealing the gap between the collection tube 3 and the inner wall of the hole, thereby effectively avoiding the problem of sap waste caused by the sap in the tree trunk flowing out through the gap during drainage, and at the same time avoiding external dust, mud, grass and other impurities from entering the hole along the gap between the collection tube 3 and the inner wall of the hole under the action of wind, causing contamination of the drained juice. By rotating the outer sleeve 202 in the opposite direction, the expansion of the rubber tube 101 can be released, thereby conveniently taking the collection tube 3 out of the hole.

[0024] Further as Figure 2 As shown, it is worth explaining in detail that a rubber protrusion 5 is arranged on the outer wall of the rubber tube 101, and a plurality of rubber protrusions 5 are arranged and the plurality of rubber protrusions 5 are equidistantly distributed; in specific operation, when the rubber tube 101 expands, the plurality of rubber protrusions 5 are arranged to further fill the irregular gap between the outer wall of the rubber tube 101 and the inner wall of the hole, thereby improving the sealing and filling effect of the gap.

[0025] The scheme has the following working process: first, a hole is drilled in the tree trunk, the size of the hole is slightly larger than the outer diameter of the rubber tube 101, and at this time, there is a certain gap between the outer wall of the rubber tube 101 and the inner wall of the hole, so that the end of the collection tube 3 with the rubber tube 101 can be easily inserted into the hole, and the outer sleeve 202 is held by hand and rotated to make the outer sleeve 202 approach the direction of the rubber tube 101, and the outer sleeve 202 synchronously drives the connecting rod 201 to rotate, thereby driving the annular piston plate 101 through the connecting rod 201 6 is rotated inside the middle sleeve 104, and then the liquid inside the middle sleeve 104 is squeezed and transported to the first inner cavity 102 through the annular piston plate 106 through the infusion tube 103, so that the rubber tube 101 expands, and the side wall of the rubber tube 101 is tightly attached to the inner wall of the hole, so that the gap between the collection tube 3 and the inner wall of the hole is fully filled and blocked. When the rubber tube 101 expands, the irregular gap between the outer wall of the rubber tube 101 and the inner wall of the hole is further filled by the multiple rubber protrusions 5.

[0026] Further Figure 2 As shown, it is worth explaining in detail that a rubber sleeve 203 is fixed on the outer wall of the outer sleeve 202, and a plurality of annularly distributed convex ribs 204 are provided on the surface of the rubber sleeve 203; during specific operation, the friction force when holding the outer sleeve 202 is effectively improved by the provided rubber sleeve 203 and the convex ribs 204, thereby improving the effort-saving operation of rotating the outer sleeve 202.

[0027] Further Figure 4 As shown, it is worth explaining in detail that a flange 9 for stopping the annular piston plate 106 is provided at one end of the center sleeve 104 close to the joint sleeve 4; during specific operation, the annular piston plate 106 is stopped and limited by the provided flange 9, thereby avoiding excessive rotation of the outer sleeve 202, which would cause the annular piston plate 106 to fall out of the center sleeve 104.

[0028] In summary: insert one end of the collection tube 3 with the filling component 1 into the hole, push the liquid into the filling component 1 through the rotary push component 2, so that the filling component 1 expands, and the gap between the collection tube 3 and the inner wall of the hole is fully filled and sealed by the filling component 1, thereby effectively avoiding the problem of sap waste caused by the sap in the trunk flowing out through the gap during drainage, and at the same time avoiding external dust, mud, grass and other impurities from entering the hole along the gap between the collection tube 3 and the inner wall of the hole under the action of wind, causing contamination of the drained juice.
