Description
Technical Field
The invention relates to the technical field of corn emasculation equipment, in particular to an unmanned corn emasculation vehicle.
Background
The removal of male flowers of the corn is beneficial to reducing the selfing rate of female parents of the corn plants, improving the quality of the corn seeds, and simultaneously changing the conveying direction of nutrient absorption and production of the corn plants, so that more nutrient substances are conveyed to the corn grains, and the corn is promoted to be mature in advance. In the actual production operation process, due to the difference of the corn growth vigor, the conventional large-scale corn emasculation equipment is difficult to completely cut off male flowers at one time, a small amount of scattered male flowers still remain, the growth and the quality of corn grains are adversely affected, and particularly in a corn seed production field, the male flowers must be cut off in time. For small and dispersed plants to be emasculated, the cost would be increased if conventional large corn emasculation equipment were still used. At present, the male flowers are mainly cut off manually for a small number of scattered plants to be emasculated.
CN209732224U discloses a corn castration machine, its castration system adopts flexible cutting knife to cut the stamen of corn plant, can adjust the cutting height of cutting knife through hydraulic means, utilizes the chain to transmit the power on the tractor wheel to the transmission shaft, drives the cutting knife rotation through bevel gear meshing transmission. It has problems in that: because all the cutting knife power comes from the transmission shaft, the cutting knives can only rotate or stop together, so when a small amount of scattered plants to be castrated face, the utilization rate of the cutting knives is low; the working heights of the plurality of male cutting systems are adjusted by a hydraulic device, so that male flowers of corns cannot be cut off simultaneously when castration is carried out under the condition that the heights of all rows of plants are different.
