Automatic pesticide spraying system

Abstract

The invention provides an automatic pesticide spraying system, comprising two supports arranged among field ridges during use; a fixing arm higher than plants is arranged on the top of the supports and extends to outer sides of the two supports to cover multiple field ridges; traveling wheel carriers are arranged at bottoms of the supports and provided with traveling drive mechanisms for driving the supports to walk along tracks; the supports are provided with steering drive mechanisms to drive the traveling wheel carriers to steer; pesticide spraying devices and water tanks are arranged on the supports or the fixing arm, the pesticide spraying devices are connected with the water tanks through pipelines, and a plurality of adjustable spray booms are hung on the fixing arm; a plurality ofnozzles aligning to the plants are arranged on the adjustable spray booms from top to bottom, and are connected with the pesticide spraying devices through pipelines. The automatic pesticide sprayingsystem can cover field ridges within a large range to realize pesticide spraying to the plants; the adjustable spray booms which are hanging can provide a guarantee to uniform distribution of pesticide sprayed to the plants; a truss type light structure is adopted so that dead weight of the system can be reduced.

Description

technical field [0001] The invention relates to the field of farm equipment, in particular to an efficient automatic spraying system. Background technique [0002] The existing farmland spraying usually uses manual or electric sprayers to spray pesticides, which has the problems of low efficiency, high labor intensity and poor safety protection. Also have the scheme that adopts mechanical equipment to spray pesticide in the prior art. For example, Chinese patent document CN107593677A is a rail-type intelligent pesticide spraying vehicle. It includes a sliding track, a support pole, a tractor, a pesticide dilution tank and two spraying devices. The support pole is erected on the field ridge. On the support rod, the tractor is slidably arranged on the first sliding track, the pesticide dilution tank is arranged on the bottom plate of the tractor, and the two spraying devices are symmetrically distributed on both sides of the tractor , which improves the spraying efficiency,...

Problems solved by technology

It includes a sliding track, a support pole, a tractor, a pesticide dilution tank and two spraying devices. The support pole is erected on the field ridge. On the support rod, the tractor is slidably arranged on the first sliding track, the pesticide dilution tank is arranged on the bottom plate of the tractor, and the two spraying devices are symmetrically distributed on both sides of the tractor , which improves the spraying efficiency, but in addition to the high cost of the tractor itself, the cost of constructing a support rod with sufficient load-bearing capacity is relatively high due to the heavy weight of the tractor

And the pesticides are sprayed from the top. For some plants with luxuriant branches and leaves, it is difficult to distribute the pesticides evenly on the plants.

Chinese patent document CN108835073A describes a pesticide spraying device for agricultural greenhouses, including an upper support plate, a liquid medicine tank is connected to the upper surface of the upper support plate by bolts, and a water pump is connected to the lower end of one side of the liquid medicine tank by bolts. The water inlet of the water pump is connected to the lower end of one side of the liquid medicine tank through a conduit. The lower surface of the support plate at the upper end is provided with a sliding track, which can drive the threaded rod to rotate through the motor, and can drive the sliding connection seat to move through the threaded rod. The movement drives the water spray pipe to move, and the plants in the greenhouse can be sprayed with pesticides through the water spray pipe, and the pesticide in the liquid medicine tank can be pumped into the water spray pipe through the water pump, and the pesticide can be sprayed through the atomizing nozzle on the water spray pipe. The speed of the pesticide spraying device in the plan is too slow, and there is also the problem that the sprayed pesticides are difficult to distribute evenly on the plants
