Improved Design And Experimental Study Of 9DSX-35-type Spraying Machine

At present, the grassland ecological destruction is more serious in our country, the rat is the main factor of rodents in grassland ecological restoration has important significance.9 DSX-35 poison bait spray machine is suitable for grassland rodents special-purpose machinery, but there are row poison bait jams, poison bait phenomenon such as spray tube oscillation instability or deformation of frame, and the driver can’t timely found the problem. If this problem cannot be solve in time, will seriously affect the poison bait was used the quality and efficiency of the spray machine, it is necessary to poison bait spray machine to improve the optimization.To solve poison bait spray machine of row poison bait blocking phenomenon during operation, the first thing to understand poison bait spray machine principle of work, it is concluded that the fan speed is the main factors influencing the row poison bait is blocked. Through different speed test of the fan, it is concluded that when the fan exceed speed of 2200 r/min, discharge poison bait unobstructed, this paper designed a fan rotational speed and the working situation of the platoon poison bait interactional row poison bait, automatic control system. When the fan speed to 2200 r/min, electromagnetic clutch and system control, row poison bait operation, discharge poison bait; On the contrary, when the fan rotation speed below 2200 r/min, row poison bait stop, do not discharge poison bait. After a performance test bench test, row poison bait machine automatic control system can effectively solve the row poison bait, blocking phenomenon.Affect the poison bait spray machine spray uniformity are the main factors of spray cone of oscillation frequency, when working in different terrain, must be steady the oscillation frequency of spray cone. This paper designed the spray cone oscillation frequency control device, can adjust the speed of the drive motor, to control the oscillation frequency of the spray cone, effectively solve the poison bait uniformity of spray.At the same time, considering the change of grassland terrain, poison bait of the spray machine frame deformation of vulnerable to turbulence and appear in the process of operation, the finite element analysis in this paper, the frame model, it is concluded that the results of the analysis, the current frame rigidity meet the requirements, the deformation of frame is due to the intense turbulence of once in a while.
