Description

Technical Field

[0001] The utility model relates to the field of environmental protection agriculture, in particular to a driving device for a telescopic anti-hail net. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The hail net is an artificial isolation barrier covering the agricultural shed, which keeps out rain, snow, hail, etc., thereby protecting the good growth of crops. When facing rain, snow, and hail, the staff needs to lay the hail net in advance and quickly. However, when agricultural sheds are in use, there are mostly a large number of sheds in the same range. The laying of a hail net requires several people to work together to make the hail net well laid, so a large number of staff are needed in a short time, which will affect other work. How to reduce the mobilization of staff, reduce the impact on other work, and at the same time complete the laying of the hail net well is a problem to be solved.

[0004] For the traditional hail net, the workers need to operate in two directions to cover and open the net. However, the pull rope will be placed there after one operation. Therefore, when the workers use it for the second time, they need to pass through the agricultural shed to operate the hail net. Therefore, how to reduce the process of workers passing through the agricultural shed and make the hail net easier to stretch is a problem to be solved. Utility Model Content

[0016] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0017] The utility model is a driving device for a telescopic anti-hail net, the main structure of which includes a frame 1, a rotating wheel 2, and a driving member 3. The frame 1 provides a supporting function for the installation of the entire device, and the setting of the frame 1 enables the device to be installed on a supporting column or a wall of an agricultural shed, and the upper and lower top surfaces of the frame 1 are hollow, as shown in the accompanying drawings of the specification. Figure 1-3 As shown, the rope chain 7 that contacts the track 6 on the rotating wheel 2 when in use can be connected to the anti-hail net. In order to better pull the anti-hail net, that is, the rotation of the rotating wheel 2 drives the movement of the rope chain 7, it is necessary to ensure the friction between the rotating wheel 2 and the rope chain 7, so that the rotating wheel 2 can drive the rope chain 7 to move while rotating. Therefore, when setting, the diameter of the rotating wheel 2 needs to be set larger to ensure the friction between the rope chain 7.

[0018] The rotating wheel 2 is provided with a plurality of tracks 6. In order to allow a rope chain 7 to pass through all the tracks 6 on the rotating wheel 2, two rotating wheels 2 are provided here, so that the rope chain 7 on the rotating wheel 2 is arranged in an "8" shape, so that one rope chain 7 passes through a plurality of tracks 6. Since one rope chain 7 passes through a plurality of tracks 6, when the rotating wheel 2 rotates, the friction between the rope chain 7 and the rotating wheel 2 increases, so that the rotation of the rotating wheel 2 can drive the movement of the anti-hail net. In order to allow the rotating wheel 2 to rotate normally, a connecting shaft 4 is provided between the rotating wheel 2 and the frame 1. In order to ensure the rotation of the connecting shaft 4, a bearing 5 is provided between the connecting shaft 4 and the frame 1, so that the connecting shaft 4 can rotate.

[0019] The driving member 3 can be divided into two types here. The driving member 3 is a driving motor 8. During the whole use process, the driving motor 8 drives the rotating wheel 2 to rotate, so that the rope chain 7 drives the anti-hail net to move. At this time, it is necessary to manually observe the movement of the anti-hail net on one side, so as to stop the rotation of the driving motor 8 at any time. The driving motor 8 here uses a motor that can rotate forward and reverse, so that the anti-hail net can achieve two movements of opening and closing. A support plate 9 is also provided below the driving motor 8, and the support plate 9 provides a support function for the driving motor 8. In order to achieve good support, the support plate 9 is integrally arranged with the frame 1, so that the driving motor 8 can drive the rotation of the connecting shaft 4. The driving motor 8 preferably uses a motor with a brake function, that is, the driving motor 8 rotates when it is powered on and stops rotating after the power is off. This kind of driving motor 8 can be purchased online, so it will not be described in detail.

[0020] The driving member 3 is a crank 10, and the driving member 3 at this time needs to be rotated manually to drive the opening and closing of the anti-hail net. Since the length of the agricultural scaffold is relatively long, if it is driven manually, the crank 10 needs to be rotated more times. Therefore, in order to reduce the number of rotations and reduce the influence of inertia during rotation. Therefore, a reducer 11 is provided between the crank 10 and the connecting shaft 4. The setting of the reducer 11 reduces the number of rotations of the crank 10 when it is rotated, and the reducer 11 also acts as a brake, that is, after the crank 10 stops turning, the anti-hail net can stop moving in time, which acts as a brake. And through different rotation directions, the crank 10 can complete the two movements of opening and closing the anti-hail net.

[0021] To sum up, the multiple rotating discs 2 are provided on the frame 1 and the multiple tracks 6 are provided on the rotating disc 2 to increase the friction when the rope chain 7 contacts the rotating disc 2, so that when the driving member 3 drives the rotating disc 2 to rotate, the rope chain 7 can rotate together, thereby reducing the occurrence of slipping and the like.

[0022] Detailed instructions for use:

[0023] The driving member 3 drives the rotating wheel 2 to rotate, and the rotating wheel 2 drives the rope chain 7 to move through the friction between the rotating wheel 2 and the rope chain 7, and the two ends of the rope chain 7 are connected to the two ends of the hail protection net, so as to realize the opening and closing states of the hail protection net. When the movement state of the hail protection net needs to be changed, it is necessary to make the driving member 3 rotate in the opposite direction.

[0024] In summary, the device reduces the manpower and other resources required for the staff to open and close the anti-hail net by setting a plurality of rotating wheels 2 and driving the rotating wheels 2 to rotate through the driving member 3. This allows one staff member to complete this operation. In addition, the device is fixed at one place of the agricultural shed and the position is fixed, which reduces the staff's shuttle through the shed to find the pull rope to pull the anti-hail net. In addition, the driving member 3 of the device includes a driving motor 8 and a crank 10, so that the device can adapt to different environments and other situations.
