Abstract
The invention relates to a trolley type enhanced-suction knapsack mower, belonging to the technical field of agricultural mowers. The trolley type enhanced-suction knapsack mower comprises a mower body, a motor, a cutter housing, and a blade connected with a motor output shaft, wherein the motor and the cutter housing are fixed on the mower body; the blade is accommodated inside the cutter housing; the interior of the cutter housing is provided with a clipped-grass conveying channel along the upper part of the blade to the outside of the cutter housing; two airflow accelerating pipelines which are oppositely arranged are fixed to the mower body; the inlets of the two airflow accelerating pipelines are connected with air pumps; the outlets of the two airflow accelerating pipelines are arranged at the clipped-grass conveying channel and accelerate airflow inside the clipped-grass conveying channel; the outlet of each air-flow accelerating pipeline is inclined to the outflow direction of the airflow inside the clipped-grass conveying channel; an angle of 120 DEG is formed between the outlets of the two airflow accelerating pipelines; and the outlet sections of the two air-flow accelerating pipelines are necking sections. The trolley type enhanced-suction knapsack mower provided by the invention has the advantages of low requirements for design and manufacturing of the blade.
Description
Technical field
The present invention relates to a kind of mower, belong to agriculture mower technical field.
Background technology
Existing mower carries out the course of work of mowing, the blade mainly utilizing its leading edge place in rotation direction of blade to be formed is mowed, and is formed with air-lift unit part at the rear of these blades for generation vortical flow with promote air-flow and carry out carrying out transport process to the broken leaf of mowing.
According to the applicant understood, when blade runs up, various whirlpool can be formed at blade rear portion, thus affect the working effect of mower.Mower blade should carry out mowing again for generation of vortical flow with promote air-flow to carry out transport process to the broken leaf of mowing, and mower blade wants simultaneously perfection realize above-mentioned two functions, and the Design and manufacture for mower blade requires higher.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, and the Design and manufacture proposing a kind of blade requires that lower cart type strengthens the negative mower of suction.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of cart type strengthens inhales negative mower, comprise fuselage, motor, cutter shell and the blade be connected with motor output shaft, described motor and cutter shell are all fixed on fuselage, described blade is contained in cutter shell, be shaped with in described cutter shell above blade to the grass bits Transfer pipe outside cutter shell, described fuselage is fixed with two the airflow speed increasing pipelines be oppositely arranged, article two, the import of airflow speed increasing pipeline is all connected with air pump, article two, the outlet of airflow speed increasing pipeline is all located at grass bits Transfer pipe place and grass is considered to be worth doing the air-flow acceleration in Transfer pipe, the outlet of every bar airflow speed increasing pipeline is tilted to the outflow direction of air-flow in grass bits Transfer pipe, article two, arrange in 120 ° of angles between the outlet of airflow speed increasing pipeline, article two, the outlet section of airflow speed increasing pipeline is all made as reducing section.
The beneficial effect that the present invention brings is: 1) the present invention is by being fixed with an airflow speed increasing pipeline with it, the import of this airflow speed increasing pipeline is connected with air pump, grass bits Transfer pipe place is located in the outlet of this airflow speed increasing pipeline and the air-flow of being considered to be worth doing by grass in Transfer pipe accelerates, like this, original blade can carry out more efficient mowing, simultaneously when mowing, original blade runs up and in the vortical flow of blade rear portion formation and can promote air-flow, at this moment, by airflow speed increasing pipeline, the air-flow in grass bits Transfer pipe is accelerated, the air-flow that the air-flow that airflow speed increasing pipeline is added and original blade produce superposes mutually, the air-flow produced for original blade makes full use of, Design and manufacture for blade is required lower, and it is also lower to the air flow demand of airflow speed increasing pipeline generation, 2) by fuselage being fixed with two the airflow speed increasing pipelines be oppositely arranged, the outlet of every bar airflow speed increasing pipeline is tilted to the outflow direction of air-flow in grass bits Transfer pipe, article two, arrange in 120 ° of angles between the outlet of airflow speed increasing pipeline, better can accelerate the air-flow in grass bits Transfer pipe, must require lower for the Design and manufacture of blade, 3) due to the outlet section of two airflow speed increasing pipelines is all made as reducing section, the air-flow of airflow speed increasing pipe outlet is accelerated, mutually can superpose by air-flow that is better and original blade generation, the Design and manufacture for blade is required lower.
The improvement of technique scheme is: described motive power of air pump input and motor power output pass through chain gear transmission.
The improvement of technique scheme is: described fuselage is provided with the convenient handle gripped.
The improvement of technique scheme is: described fuselage is provided with by LED light.
Accompanying drawing explanation
Strengthen the negative mower of suction below in conjunction with accompanying drawing to cart type of the present invention to be described further.
Fig. 1 is that the cart type of the embodiment of the present invention strengthens the negative mower structural representation of suction.
Fig. 2 is the structural representation of the airflow speed increasing pipeline exit of Fig. 1.
Embodiment
Embodiment
The cart type of the present embodiment strengthens inhales negative mower, as depicted in figs. 1 and 2, and the blade comprising fuselage 1, motor, cutter shell 2 and be connected with motor output shaft.Motor and cutter shell equal 2 are fixed on the fuselage 1, and blade is contained in cutter shell 2, are shaped with above blade to the grass bits Transfer pipe 5 outside cutter shell in cutter shell 2.
Import fuselage 1 being fixed with two airflow speed increasing pipelines, 3, two the airflow speed increasing pipelines 3 be oppositely arranged all is connected with air pump, and grass bits Transfer pipe place is all located in the outlet of two airflow speed increasing pipelines 3 and the air-flow of being considered to be worth doing by grass in Transfer pipe accelerates.
The outlet of every bar airflow speed increasing pipeline 3 is tilted to the outflow direction of air-flow in grass bits Transfer pipe 5, arranges between the outlet of two airflow speed increasing pipelines in 120 ° of angles.Article two, the outlet section of airflow speed increasing pipeline 3 is all made as reducing section.That is, the outlet section of airflow speed increasing pipeline 3 is reduced successively.
Motive power of air pump input and the motor power output of the present embodiment pass through chain gear transmission.Certainly, motive power of air pump input and motor power output also can pass through pulley drive.
The fuselage of the present embodiment is provided with the convenient handle 4 gripped.
The fuselage of the present embodiment is provided with by LED light.
