Description

Technical Field

[0001] The utility model belongs to the technical field of agriculture, and in particular relates to a tobacco field ridge inter-ridge herbicide spraying protection device. Background Art

[0002] During the tobacco cluster period, it is necessary to spray herbicides between the tobacco ridges to prevent weeds from growing and competing with tobacco seedlings for nutrients. However, when spraying herbicides, it is necessary to shield the tobacco to prevent the herbicides from being sprayed on the tobacco plants, causing poisoning of the leaves or even the entire plant. In the prior art, tobacco farmers use truncated plastic tubes to cover the tobacco seedlings, and pull the plastic tube covers synchronously with the movement of the spraying position, so as to shield the herbicides sprayed on the tobacco seedlings. Although the manufacturing cost is low, it requires the cooperation of multiple people when spraying herbicides, that is, one person sprays the agent, and when spraying herbicides between the tobacco ridges, someone needs to pull the protective cover on both sides of the tobacco ridges, which increases the labor cost and the spraying efficiency is not high.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1As shown, it is a schematic structural diagram of a tobacco field inter-ridge herbicide spraying protection device of a preferred embodiment of the utility model. The tobacco field inter-ridge herbicide spraying protection device of this embodiment includes protective covers 100 arranged opposite to each other on two sides. The bottoms of the protective covers 100 on both sides are concave, and the concave parts of the bottoms of the protective covers 100 on both sides respectively cover the outside of the tobacco on the two sides of the tobacco ridges. Both sides between the protective covers 100 on both sides are detachably connected with shielding plates 300. The shielding plates 300 on both sides connect the protective covers 100 on both sides and can shield the herbicide sprayed between the protective covers 100 on both sides to prevent the herbicide from being blown onto tobacco elsewhere due to wind direction. Liquid storage tanks 200 are installed on the protective covers 100 on both sides. Herbicide is added to the liquid storage tanks 200 on both sides and sprayed between the protective covers 100 on both sides, thereby reducing manpower input, improving the efficiency of spraying herbicides, and providing more comprehensive protection for tobacco.

[0025] like Figure 2 As shown, it is a schematic diagram of the protective cover structure in this embodiment, the bottom sides of the protective covers 100 on both sides are embedded with track wheels 103 that are rotatably connected, the outer walls on both sides of the protective covers 100 are detachably connected with drive motors 104, and the output ends of the drive motors 104 on both sides are detachably connected to the track wheels 103 on both sides. In this embodiment, the drive motors 104 on both sides rotate to drive the track wheels 103 on both sides to rotate, so that the protective cover 100 can automatically move along the chimney, and through the different rotation directions of the drive motors 104 on both sides, the protective cover 100 can be turned around, making it more convenient to use.

[0026] like Figure 2 , Figure 3 as well as Figure 4 As shown, it is a protective cover, a liquid storage tank and a spray pipe in this embodiment. Figure 3 In the enlarged structural diagram at A in the middle, the upper ends of the protective covers 100 on both sides are provided with mounting grooves 101, and the liquid storage tanks 200 on both sides are embedded in the mounting grooves 101. The inner walls of the opposite surfaces of the protective covers 100 on both sides are provided with mounting holes 102. The interiors of the mounting holes 102 on both sides are embedded with delivery pumps 204. The liquid inlet ends of the delivery pumps 204 on both sides are respectively connected to the liquid storage tanks 200 on both sides, and the liquid outlet ends of the liquid storage tanks 200 on both sides are respectively connected to the connecting pipes 202. The connecting pipes 202 on both sides are connected to the liquid storage tanks 200 on both sides. A spray pipe 203 is detachably connected between the two sides, and a plurality of spray holes are arranged on the outer wall of the spray pipe 203 on both sides near the bottom. A liquid filling port 201 is arranged on the liquid storage tank 200 on both sides. In this embodiment, the herbicide inside the liquid storage tank 200 on both sides is extracted and transported to the inside of the connecting pipes 202 on both sides by the delivery pumps 204 on both sides, and then enters the inside of the spray pipe 203 and is sprayed downward from the spray hole at the bottom, so that the herbicide can be sprayed between the two sides of the chimney when the protective covers 100 on both sides move.

[0027] like Figure 4 As shown, in order to achieve a better spraying effect, in this embodiment, a solenoid valve 205 is installed between the liquid outlet end of the delivery pump 204 on both sides and the connecting pipe 202. When spraying, the solenoid valve 205 on one side is closed and the solenoid valve 205 on the other side is opened. First, the herbicide inside the liquid storage tank 200 on one side is sprayed. After the spraying of the herbicide inside the liquid storage tank 200 on one side is completed, the solenoid valve 205 on the other side is closed and the solenoid valve 205 on one side is opened to spray the solenoid valve 205 on the other side, so as to avoid the herbicides inside the liquid storage tanks 200 on both sides colliding in the spraying pipe 203, resulting in excessive spraying pressure, increased consumption of herbicides and waste.

[0028] like Figure 5 As shown, it is a schematic diagram of the shielding plate structure in this embodiment, the shielding plate 300 includes a first L-shaped plate 301 and a second L-shaped plate 302 arranged relatively to each other, and one side horizontal edge of the first L-shaped plate 301 and the second L-shaped plate 302 are detachably connected to the outer walls of the protective covers 100 on both sides, and the outer wall of the first L-shaped plate 301 or the second L-shaped plate 302 is fixedly connected with a sliding plate 303 that is slidably connected to the inside of the first L-shaped plate 301 or the second L-shaped plate 302. In this embodiment, the sliding of the sliding plate 303 can adjust the distance between the two protective covers 100 according to the distance between the chimneys on both sides of the operation, and the spray pipe 203 can also be replaced with spray pipes 203 of different lengths according to the distance between the chimneys on both sides, so that the application range is wider.
