Description

Technical Field

[0001] This utility model relates to the technical field of tea tree cultivation equipment, and in particular to a height-adjustable tea tree netting release and take-up device. Background Technology

[0002] A tea tree shading netting device is a mechanical device that covers the surface of tea trees with shade nets or other mesh fabrics. It is usually equipped with a walking component for simultaneous use, that is, the shading netting device is fixed on a walking machine, such as a tracked power machine, and then the shading netting is covered and stored by the forward and reverse rotation of the winding drum.

[0003] Existing shading netting devices are usually fixed, which makes it difficult to adjust the height relative to the surface of the tea tree. This results in the winding drum not rotating smoothly during shading and storage, and may even cause the net to break when it gets stuck between the shading net and the tea tree and is pulled hard.

[0004] In addition, the winding drum requires a speed reducer, which not only increases the overall weight but also raises the overall operating cost of the device. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-4 .

[0030] A height-adjustable tea tree netting device includes a base 1 for mounting the netting device. The base 1 is fixedly connected to a walking component, which drives the tea tree netting device to move within the tea garden to perform netting.

[0031] The walking component can be a tracked chassis walking component, adapted to provide all-terrain coverage for tea trees in hilly areas.

[0032] The base 1 is provided with a swing arm 3, which is symmetrically arranged on both sides of the base 1. A rotating shaft 301 is provided in the middle of the swing arm 3. The rotating shaft 301 is rotatably mounted on the vertical plates on both sides of the base 1, and multiple bearings can be provided between the rotating shaft 301 and the vertical plates to improve the rotation effect.

[0033] The swing arm 3 includes a first arm body 302 located on the side of the rotating shaft 301 facing the walking direction of the walking component and a second arm body 303 located on the other side of the rotating shaft 301. A winding cylinder 2 is rotatably provided between the two first arm bodies 302. The winding cylinder 2 is used to wind up and unfold the shade net to cover and store the tea tree.

[0034] The winding drum 2 achieves height adjustment relative to the base 1 by driving the first swing arm 302 to swing around the rotating shaft 301 through the second swing arm 303. Preferably, the first swing arm 302 and the second swing arm 303 are integrally formed, and the arm length of the second swing arm 303 is greater than that of the first swing arm 302. Thus, when a swinging force is applied to the second swing arm 303, the application of the swinging force is reduced by the leverage force, and the swinging and lifting of the winding drum 2 is also realized. The length ratio of the second swing arm 303 to the first swing arm 302 is preferably 1.1:1-3:1.

[0035] A connecting shaft 305 is provided between the second arm bodies 303 on both sides. The connecting shaft 305 is located at the end of the second arm body 303 away from the first arm body 302. A connecting plate 306 is provided in the middle of the connecting shaft 305. A lifting unit 4 is provided between the connecting plate 306 and the base 1.

[0036] The lifting unit 4 includes a fixed base 401 and a push rod 402. The fixed base 401 is rotatably connected to the base 1 via a pin, and the push rod 402 is rotatably connected to the connecting plate 306 via a pin. By extending and shortening the push rod 402 relative to the fixed base 401, the height of the connecting shaft 305 relative to the base 1 can be increased and decreased. Furthermore, when the height of the connecting shaft 305 relative to the base 1 increases, the height of the winding drum 2 at the end of the first arm 302 relative to the base 1 is shortened by rotating the rotating shaft 301, and vice versa. That is, the winding drum 2 can be oscillating and lifting by driving the lifting unit 4.

[0037] like Figure 3 As shown, a stiffening plate 307 is provided between the two symmetrically arranged swing arms 3. The stiffening plate 307 is provided with a plurality of weight-reducing holes 308, so that the two swing arms 3 form a whole after being connected by the stiffening plate 307, forming a large swing component. The weight reduction through the weight-reducing holes 308 reduces the overall mass of the swing component.

[0038] The swing arm 3 is equipped with a motor 5 for driving the winding drum 2 to rotate. The motor 5 can be fixed on the stiffening plate 307. The motor 5 is equipped with a first transmission wheel 501. The winding drum 2 is equipped with a second transmission wheel 201 that is connected to the first transmission wheel 501. The first transmission wheel 501 and the second transmission wheel 201 can be connected by a belt or a synchronous belt. The diameter of the first transmission wheel 501 is larger than that of the second transmission wheel 201, thereby achieving a speed reduction effect through the diameter ratio of the transmission wheels. Furthermore, by setting the motor 5 on the swing arm 3, the overall space occupied by the net-covering and unloading device on the traveling component can be reduced.

[0039] A locking assembly is provided between the rotating shaft 301 and the base 1. The locking assembly includes a locking gear 101 fixed on the rotating shaft 301. Specifically, the rotating shaft 301 on either side of the swing arm 3 passes through the vertical plate of the base 1 and is fixedly connected to the locking gear 101. The base 1 is provided with a locking push rod 102 that cooperates with the locking gear 101. The locking push rod 102 is provided with a locking tooth 103. The locking push rod 102 drives the locking tooth 103 to lock or disengage from the tooth groove on the locking gear 101. Initially, the locking tooth 103 slides downward and disengages from the locking gear 101. At this time, the lifting unit 4 drives the swing arm 3 to swing, causing the locking gear 101 to rotate. After the adjustment is completed, the locking push rod 102 drives the locking tooth 103 to mesh with the locking gear 101, thereby locking the locking gear 101 in its relative position with the base 1, achieving relative fixation and improving safety.

[0040] In this embodiment, the lifting unit 4 and the locking push rod 102 are electric push rods, but push rods with other power sources can also be used instead, and no further limitation is made here.

[0041] The method of using the height-adjustable tea tree netting and unloading device described above is as follows: In use, the locking push rod 102 drives the locking tooth 103 to slide downward so that it disengages from the locking gear 101. Then, the lifting unit 4 realizes the swing arm 3 swinging around the rotating shaft 301 through the extension and retraction of the push rod 402, thereby realizing the height adjustment of the winding drum 2 relative to the base 1. After the adjustment is completed, the locking push rod 102 drives the locking tooth 103 to slide upward and engage with the locking gear 101, so that the locking gear 101 is fixed relative to the base 1, thereby fixing the swing arm 3. Furthermore, the winding drum 2 is fixed in the adjusted position.

[0042] In addition, when the winding drum 2 swings while the tea tree shading net is being covered or unwound by the tea tree shading netting device, the swaying motion allows the shading net to disengage from the tea tree surface when it is locked in place, thus preventing the shading net from being damaged by being pulled too hard.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
