Description

Technical Field

[0001] This invention relates to an overweight automatic unhooking device for birch sap collection, belonging to the field of birch sap collection equipment. Background Technology

[0002] The current common method for collecting birch sap is to fix the collection container to the tree trunk with a rope, and then insert the collection tube into the container or place it on top of the container. Although this method can collect birch sap, it requires the collector to check the collection status regularly. If the time is missed, the excess birch sap in the container will overflow, resulting in waste. Furthermore, if an unsealed container such as a bucket is used for collection, although more sap can be collected at once, it is easy for the sap to become contaminated. Therefore, it is necessary to improve this method. Summary of the Invention

[0003] The purpose of this invention is to solve the aforementioned problems in the background art and to provide an overweight automatic unhooking device for birch sap collection.

[0004] The present invention achieves the above objectives by adopting the following technical solution: An overweight automatic unhooking device for birch sap collection includes a fixing device; a hanging ring is fixedly connected to the lower end of the fixing device, and multiple sap collection bags are provided on the hanging ring; a limiter is also fixedly connected to the lower end of the fixing device, and a collection tube inserted into the tree trunk is provided on the limiter; a rotatable device is also rotatably connected to the lower end of the limiter; multiple insertion tubes are provided at the lower end of the rotatable device, each insertion tube communicating with a corresponding sap collection bag. Compared with the prior art, the beneficial effects of the present invention are: the present invention not only provides multiple collection bags, but also automatically replaces them with adjacent collection bags after one bag is full to continue collecting, thus avoiding waste; and allows the collector to set an appropriate number of collection bags according to the thickness of the tree to fix the sap collection volume and avoid collecting too much sap from the same tree, which could affect tree growth.

Detailed Implementation

[0006] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0007] Specific implementation method one: as follows Figure 1-9 As shown in the figure, this embodiment describes an overweight automatic unhooking device for birch sap collection, including a fixator 2; a hanging ring 3 is fixedly connected to the lower end of the fixator 2, and multiple sap collection bags 4 are provided on the hanging ring 3; a limiter 5 is also fixedly connected to the lower end of the fixator 2, and a collection tube 6 inserted into the tree trunk 1 is provided on the limiter 5; a rotator 8 is rotatably connected to the lower end of the limiter 5; multiple insertion tubes 83 are provided at the lower end of the rotator 8, and each insertion tube 83 communicates with a corresponding sap collection bag 4. By setting multiple sap collection bags 4, the collector is prevented from forgetting to collect the sap, thus avoiding overflow after the collection is full.

[0008] The limiter 5 includes a fixing plate 56; a fixing rod 57 is fixedly connected to the upper end of the fixing plate 56, and the fixing rod 57 is connected to the lower end of the fixture 2; a shaft hole 55 is provided at the center of the bottom end of the fixing plate 56, and a through hole 54 is provided at an off-center position of the fixing plate 56; one end of the collection tube 6 is placed in the through hole 54. The collection tube 6 is fixed by the fixing plate 56, which effectively prevents the collection tube 6 from falling off due to external force and affecting collection.

[0009] The rotating device 8 includes a turntable 81; the upper end of the turntable 81 is provided with a shaft 86 connected to the shaft hole 55 via a bearing; the upper surface of the turntable 81 is provided with multiple arc-shaped grooves 84, and the lower surface of the turntable 81 is provided with multiple through holes 85 communicating with the corresponding arc-shaped grooves 84; each through hole 85 is provided with an insertion tube 83. By rotating the turntable 81, different arc-shaped grooves 84 are connected to the through holes 54, and each arc-shaped groove 84 is also connected to the corresponding collection bag 4. After the turntable 81 rotates, the juice can flow into different collection bags 4.

[0010] The collection bag 4 includes a bag body 43; the top of the bag body 43 has a hole 45 for inserting a tube 83, and connecting holes are provided on both sides of the top of the bag body 43. The connecting holes are connected to hooks I 41 at one end of the connecting strap 42, and hooks I 41 at the other end of the connecting strap 42 are connected to the hanging ring 3. The bag body 43 is connected to the hanging ring 3 by the connecting strap 42 to prevent the bag body 43 from falling off after being filled with juice, which would cause the juice to spill out.

[0011] The connecting strip 42 is an elastic strip.

[0012] A rotating ring 51 is connected to the outer circumference of the fixed disk 56 by a bearing; the rotating ring 51 is provided with a plurality of slide rails I 52 and slide rails II 53 that axially penetrate the rotating ring 51; the slide rails I 52 are connected to the corresponding slide rails II 53.

[0013] The outer diameter of the rotating ring 51 is larger than the diameter of the turntable 81. This prevents the slide rod 72 from contacting the limiting plate 82 and affecting the rotation of the limiting plate 82.

[0014] The outer circular surface of the turntable 81 is provided with multiple obliquely arranged limiting plates 82.

[0015] It also includes a transmission device 7; the transmission device 7 includes a transmission block 71; the transmission block 71 is fixedly connected to the top side of the slide rod 72, the slide rod 72 is slidably engaged with the slide groove I 52, the transmission block 71 is slidably engaged with the slide groove II 53, and the transmission block 71 can pass through the gap between two adjacent limiting plates 82; the lower end of the slide rod 72 is fixedly connected to an elastic rubber belt 73, and the lower end of the elastic rubber belt 73 is fixedly connected to a hook II 74; the top of the bag body 43 is provided with a hole 44 for connecting to the hook II 74.

[0016] When birch sap is collected in the bag 43, the bag 43 moves downward as the weight increases.

[0017] The working principle of this invention is as follows: When using this device, after drilling a hole in the tree, install the collection tube 6, install the fixing device 2 above the tree hole, so that the fixing plate 56 is located below the tree hole, and insert the lower end of the collection tube 6 into the perforation 54, ensuring that the perforation 54 is connected to any arc groove 84; then insert the insertion tube 83 into the corresponding bag body 43, and connect the hooks I 41 at both ends of the connecting strap 42 to the bag body 43 and the hanging ring 3 respectively to complete the installation; depending on the thickness of the tree, without affecting the normal growth of the tree, the thicker the tree, the more sap can be collected, and more collection bags 4 can be set. When the collector collects, once all the initially set collection bags 4 are full, collection stops to avoid affecting the normal growth of the tree. At the same time, the collection volume is fixed by the collection bags 4 during the initial collection, avoiding the situation where only one collection container is set each time, which would cause the collector to forget the volume of the collected solution after multiple collections, resulting in over-collection and affecting the growth of the tree.

[0018] During the collection process, the sap flowing from the tree trunk falls into the perforation 54 through the collection pipe 6, and then flows into the arc-shaped groove 84 connected to it under the action of gravity. It then flows through the through hole 85 and the insertion tube 83 into the corresponding bag body 43. As the volume and weight of the sap in the bag body 43 increase, the bag body 43 gradually moves downwards, stretching the connecting strap 42. During this downward movement, the elastic rubber band 73 stretches. When stretched to its maximum, the elastic rubber band 73 drives the sliding rod 72 to move downwards along with it until the transmission block 71 moves downwards between two adjacent limiting plates 82. As the transmission block 71 moves downwards... The movement is achieved by pushing the turntable 81 to rotate through the inclined limiting plate 82, while the slide bar 71 is still located in the slide rail I 52. The slide bar 71 and the transmission block 72 do not rotate with the turntable 81 under the gravity of the juice in the bag body 43 and the elastic force of the connecting belt 42. After the transmission block 72 is completely disengaged from the gap between the two adjacent limiting plates 82, the turntable 81 rotates to another arc groove 84 and moves to the lower end of the perforation 54, so that the juice flows into another collection bag 4 through the perforation 54. After the transmission block 72 is disengaged from the limiting plate 82, the bag body 43 that is full of juice is also disengaged from the corresponding insertion tube 83. Subsequently, the bag 43 is moved to the bottom of the perforation 54. As the weight increases, the elastic rubber band 73 between the hook II 74 and the slide bar 72 is also stretched. Since the bag 43 cannot move left or right, the slide bar 72 is moved to the top of the hook II 74 by the elastic rubber band 73 (that is, under the action of the weight of the bag 43, the elastic rubber band 73 is moved from the inclined state to the vertical state). The above method is then repeated to collect the juice. This invention can extend the time that the collector spends checking the collection bag 4 or prevent the collector from forgetting to allow the juice in the collection bag 4 to overflow when it is full.

[0019] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
