Problems solved by technology

[0004] Chinese patent CN104908486 announced an electromagnetic paper clip binding machine on September 16, 2015. It uses electromagnetic attraction force as the power to push paper clips, and the operation time interval is difficult to adjust. Low
Since the paper clip is only lifted by the bump, it is not easy to precisely control the opening distance of the paper clip and the degree of tightness of the fixed object
At the same time, the point-and-line paper pressing device is easy to directly crush irregular and soft objects to be fixed, such as crop leaves.

Embodiment 1

[0040] see figure 1 , the agricultural water-sensitive paper clip fixing device of the present invention is mainly composed of an upper cover 1, a bolt 2, an upper platen 3, a lower platen pair 4, a base plate 5, a lower shell 6, a switch panel 7, a base 8, a tenon 9, a ball head pin 10, needle pushing mechanism and needle feeding mechanism; the upper pressing plate 3 is set on the lower pressing plate pair 4; The upper end of shell 6.

[0041] see figure 2 , the lower shell 6 is composed of a support platform and a hollow column connected to the lower end of the support platform, and has a T-shaped structure as a whole. The center position of the upper end plane of the support platform is provided with a needle feeding through hole 21 communicating with the hollow column, and a pair of bolt mounting holes on both sides. The left and right sides of the lower end of the hollow column are symmetrically provided with draw-in slots 22 , and the middle position of the lower end...

Embodiment 2

[0058] Compared with Embodiment 1, by calculating the length and moving speed of the push pin rack 51 and setting corresponding delays for the corresponding buttons on the switch panel 7, a more automated use process can be realized. Specifically, after triggering the "Start" button on the switch panel 7, the gear 52 will forwardly rotate and push the paperclip according to the set first delay time, until the inner and outer rings of the paperclip are stretched to clamp the water-sensitive paper and are fixed. Object, and then continue to push until the bump 31 no longer supports the inner ring of the paper clip, the paper clip then returns to its original shape, and the first delay time ends; automatically enters the second delay time set, the gear 52 reverses, and the push pin rack 51 Return to the initial position, the second delay time ends; trigger the first delay time again, the gear 52 rotates forward...

[0059] The above-mentioned process is carried out repeatedly, un...

Abstract

The invention discloses an agricultural water sensitive paper clip fixing device and a fixing method, and belongs to the technical field of agricultural plant protecting machinery. The fixing device comprises an upper cover, a bolt, an upper pressing plate, a lower pressing plate pair, a substrate, a lower shell, a switch panel, a base, a clamping tenon and a bulb pin; and the upper pressing plate, the lower pressing plate pair and the substrate are mounted on a T-shaped lower shell through bolt connection and closed in the upper cover. When the fixing device is used, such fixed matters as crop leaves and water sensitive papers are overlapped to put in a gap between the upper pressing plate and the lower pressing plate pair; the switch panel is pressed; and clips in a lower pressing platesecondary channel are automatically pushed out by a push needle rack to expand inner and outer rings of the clips so as to clamp the fixed matters and the water sensitive papers. The fixing device isfast and convenient to use, is low in production, use and maintenance cost, and can be widely applied to multiple application fields of agricultural production and scientific experiments.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection machinery, in particular to a mechanical device for fixing agricultural water-sensitive paper with paper clips. Background technique [0002] Agricultural water-sensitive paper is often used to measure the droplet deposition distribution test under different spraying methods to detect the effect of pesticide spraying and evaluate the performance parameters of spraying equipment. It has been widely used because of its ease of use. During the test, it is necessary to determine the number of water-sensitive papers to be placed according to the specific conditions of the crop plants. For example, for tall and dense plants, it is usually necessary to arrange the water-sensitive paper in the upper, middle and lower layers along the height direction of a single crop. , but short and sparse plants will only be arranged in two layers. However, because multiple water-sensitive paper t...
