Problems solved by technology

[0003] The period of flower urging varies with species, and the planting area is large. At present, artificial flower urging is still a main way of urging flowers; when artificial flower urging, it is difficult to control the amount of flower urging agent, which will cause waste, increase costs, and urge flowers. The flower agent will cause great harm to the human body. Ethephon is commonly used as a flower urging agent. Direct contact with the flower urging agent will cause damage to the skin, eyes, and mucous membranes. Moreover, the population is aging and the agricultural labor force is decreasing. The cost of artificial flower urging Therefore, it is of great significance to develop advanced automatic pineapple flower-driving technology and research and develop automatic pineapple flower-driving device

Embodiment 1

[0048] The sprinkler system 4 includes a water tank 4-1, a connecting pipe 4-6, a sprinkler 4-7 and a lifting device 4-8; the lifting device 4-8 includes a frame plate 4-8-1, a casing 4-8-2 and is arranged on Push rod motor 4-8-3, sliding plate 4-8-4 between frame plate 4-8-1 and shell 4-8-2; frame plate 4-8-1 is vertically installed on one end of frame 1 ;

[0049] The push rod motor 4-8-3 is fixed on the top of the frame plate 4-8-1; the sliding plate 4-8-4 is set in parallel with the push rod motor 4-8-3, and is connected with the push rod motor 4-8-3 , and at least two pieces are provided; the push rod motor 4-8-3 is electrically connected with the PLC control system 5;

[0050] The spraying device 4-7 includes a sliding track 4-7-1; the sliding track 4-7-1 is arranged horizontally, and is fixedly connected with the bottom end of each sliding plate 4-8-4; the sliding track 4-7-1 is equipped with at least 4 Each nozzle 4-7-2, the nozzle 4-7-2 is connected with a connectin...

Embodiment 2

[0053] Embodiment 2: The device has two control modes: manual and automatic. The manual control mode is mainly used to adjust the state of the equipment and debug the operation. In the automatic mode, the pineapple flower forcing equipment will move independently at a constant speed according to the set speed.

Embodiment 3

[0054] Embodiment 3: The bottom of the frame is prescribed to be connected with several beams, and the several beams strengthen the strength of the frame.

Abstract

The invention discloses a self-propelled high-clearance pineapple flower forcing machine based on PLC control. The self-propelled high-clearance pineapple flower forcing machine comprises a rack, a power system, a transmission system, a spraying system, a PLC control system and a steering system, wherein the spraying system is driven by a push rod motor to lift up and down, the distance between a spray head and a spraying position is adjusted, and the spray head can be adjusted in the horizontal direction to adapt to the change of pineapple planting line spacing; the PLC sets an advancing direction and a speed of a vehicle body, a spraying interval time of the flower forcing liquid, a spraying time of each time, the height of a spray head in the vertical direction and the maximum walking distance of the vehicle body; after the system is started, the flower forcing solution spraying system sprays a flower forcing solution to pineapple seedlings according to preset time intervals along with the constant-speed advancing of the vehicle body; a direct current permanent magnet brushless motor drives a front high land wheel through a front axle assembly; and a hydraulic steering system drives the two front wheel supporting legs to rotate to achieve steering. The machine has the advantages of high mechanization degree, convenience in operation, low cost, time and labor saving, high spraying efficiency, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a PLC-based self-propelled high-gap pineapple flower forcing machine. Background technique [0002] In pineapple planting, there are some situations that are not conducive to standardized management and picking, such as long flowering period of pineapple and uneven fruit ripening. In order to standardize management and adjust the time to market of pineapples to create greater production value, when the pineapple grows to a certain stage, it is necessary to adjust the growth of the pineapple by spraying flower-inducing agents. It can promote the ripening of the fruit to ensure that the fruit of good quality will be produced and listed on time. [0003] The period of flower urging varies with species, and the planting area is large. At present, artificial flower urging is still a main way of urging flowers; when artificial flower urging, it is difficult to control t...
