Compared with the prior art, the invention has the following beneficial effects: can be applied with pesticide and fertilizer while weeding, the invention,

(1) by arranging the driving gear, when the mower works, the driving gear can rotate, meanwhile, the driving gear can drive a plurality of driven bevel teeth to rotate, the driven bevel teeth can drive the cutting mechanism below the driven bevel teeth to rotate, so that the effect of mowing by rotating the cutting mechanism is achieved, the driven bevel teeth are from large to small from top to bottom, the driven bevel teeth can enable the matching diameters of the driven bevel teeth and the driving gear to be different by adjusting the heights of the driven bevel teeth, and therefore the rotating speed of the cutting mechanism can be automatically adjusted according to different requirements of the use environment of the mower;

(2) by arranging the cutting blade bar and the compressed curing liquid, the compressed curing liquid can increase the strength of the cutting blade bar when being extruded, so that the cutting blade bar can be gradually solidified to increase the strength of the cutting blade bar, the cutting blade bar can be changed into a normal fluid state when the pressure is recovered to be normal, when the mower is started, the cutting mechanism can rotate, the cutting blade bar below the cutting mechanism can disperse around under the action of centrifugal force and cut the contacted plants in the rotating process of the cutting blade bar, when the cutting blade bar rotates, the balancing weight in the cutting blade bar can move towards the front end of the cutting blade bar under the action of the centrifugal force, the balancing weight can extrude all the compressed curing liquid into the cutting chamber, at the moment, the compressed curing liquid in the cutting chamber can increase the strength due to the pressure rise, so that a larger impact force can be generated when one side of the cutting chamber of the cutting blade bar is contacted with the plants, the cutting machine has the advantages that plants can be cut better, meanwhile, the centrifugal force of the balancing weight becomes larger when the rotating speed of the integral cutting mechanism is increased, so that the extrusion force of the balancing weight on compressed curing liquid is larger, the strength of the compressed curing liquid in the cutting chamber is higher, when the rotating speed of the cutting mechanism is increased, more plants needing to be cut are shown, otherwise, fewer plants are cut, so that the overall strength of the cutting blade bar can be automatically controlled by the balancing weight according to the rotating speed during working, when the cutting demand is more, the strength is increased, and when the cutting demand is less, the strength is reduced;

(3) by arranging the conical tooth piston, when the cutting blade rotates to cut plants, the plants can have a reaction force on the cutting blade, when the cutting blade contacts with more plants, the reaction force is larger, the plants are more, the required cutting force is larger, otherwise, the plants are less, the required cutting force is smaller, after the cutting blade bears the reaction force, the cutting blade can inwards extrude the compressed curing liquid in the cutting chamber, when the reaction force is larger than the set value of the pressure valve, the compressed curing liquid in the cutting chamber breaks through the pressure valve, flows into the rotating speed control pipeline and finally flows to the bottom of the hydraulic chamber, at the moment, the conical tooth piston is jacked up by the compressed curing liquid flowing into the bottom of the hydraulic chamber, so that the driven conical tooth moves upwards, and the driven conical tooth moves upwards due to the fact that the conical tooth is large and small, therefore, the contact diameter of the driven bevel gear and the driving gear is reduced, so that the number of selected rotation turns of the driven bevel gear with the small diameter is larger than that of the driven bevel gear with the large diameter under the same rotation speed of the driving gear, the rotation speed of the driven bevel gear is increased, the working rotation speed of the cutting mechanism is finally increased, the overall working efficiency of the mower is improved, otherwise, when the reaction force applied to the cutting blade bar is smaller, the rotation speed is enough to meet the current cutting requirement, and the overall working efficiency of the mower can be automatically judged and adjusted according to the reaction force applied to the cutting blade bar;

(4) the pesticide preparation box is arranged, so that the wound of the plant just trimmed is large, the pest is more easily attracted, the pest can be removed by spraying pesticides, the fertilizer can supplement enough nutrition to the plant just trimmed, the situation of malnutrition caused by reduction of nutrient absorption due to lack of branches and leaves of the plant after trimming can be prevented, and the mixed liquid medicine in the mixed liquid medicine can be spilled out from the pesticide spreading port under the action of centrifugal force when the cutting blade rotates to cut the plant due to the fact that the mixed liquid medicine is located inside the cutting blade, so that independent fertilizer application and pesticide application after the grass cutting is finished can be avoided, labor cost is reduced, and meanwhile the plant can be prevented from being bitten by pests during the period of waiting for fertilizer application and pesticide application after the grass cutting, and the nutrients can be supplemented in time;

(5) by arranging the rolling wheel, the fusion catheter in front of the rolling wheel is pressed by the rolling wheel, so that the mixed liquid medicine can not pass through, and finally the liquid medicine in the fusion liquid guide pipe can only be sprinkled from the medicine sprinkling port at the rear part of the rolling wheel, the balancing weight can move towards the front part of the cutting edge strip along with the rotation of the cutting edge strip, when the rotating speed of the cutting edge strip is lower, it means that the plant is cut less, and the distance of the clump weight moving forward is less, so the rolling wheel in the clump weight also moves less, the liquid medicine in the fusion catheter is less, on the contrary, when the rotating speed of the cutting blade strip is higher, it means that more plants are cut, the distance that the rolling wheel moves forward will be longer, and therefore the available length of the fusion catheter will be greater, more spilled liquid medicine is made, so that the spilled flow of the liquid medicine can be automatically controlled according to the rotating speed of the cutting edge strip;

(6) by arranging the pesticide control ball and the fertilizer control ball, when the driven bevel gear moves upwards, the cutting requirement of the mower is increased, more plants are cut before mowing, more pests in the plants before mowing are needed, more pesticides are needed at the moment, meanwhile, pests killed by the pesticides can be used as organic fertilizers for the plants after falling on the ground, when the driven bevel gear moves upwards, hydraulic oil above the hydraulic cavity is discharged and flows into the hydraulic pipeline, the hydraulic oil in the hydraulic pipeline flows to the hydraulic bag, when the hydraulic oil flows into the hydraulic bag, the hydraulic bag expands and pushes out the extrusion rod, the extrusion rod pushes out the extrusion fluid in the pesticide control ball into the fluid pipeline, and then the extrusion fluid flows into the fertilizer control ball along with the fluid pipeline, and the fertilizer control ball expands and grows accordingly, at the moment, the pesticide control ball in the pesticide pipeline is extruded, so that the passing area of the pesticide pipeline is increased, the flow of the pesticide flowing to the gear pump is increased, the passing area of the fertilizer pipe is decreased when the fertilizer control ball in the fertilizer pipeline is increased, the flow of the fertilizer flowing to the gear pump is decreased, the effect of more pesticide and less fertilizer can be realized, otherwise, if the driven bevel gear is lowered, the cutting requirement of the existing mower is low, plants are fewer, more nutrition needs to be provided for the plants, the pesticide requirement is decreased because the plants are not too many, the driven bevel gear is lowered, the hydraulic cavity sucks away the hydraulic oil in the hydraulic bag, the extrusion rod on the surface of the hydraulic bag is retracted, the extrusion rod pulls the pesticide control ball to expand, so that the pesticide control ball sucks out the extrusion fluid from the fertilizer control ball, and the pesticide flow is decreased, the fertilizer flow is increased, so that the fertilizer and pesticide mixing proportion can be automatically adjusted according to the up-and-down movement of the driven bevel gear, and the most appropriate mixed liquid medicine can be prepared according to different use conditions.
