Abstract
The utility model relates to a vertical pulverizer for straw returning to field, belonging to an agricultural field working machine, and the vertical pulverizer for straw returning to field is matched with a tractor. The main shaft of a pulverizing system is designed into a vertical working structure perpendicular to ground. Movable cutters spirally arranged on the main shaft from right echelonment are staggered with fixed cutters in parallel in order to cut straws returning to field. The utility model avoids adverse effect brought by working blades momentarily contacting with ground. Mechanical efficiency is increased, cost is reduced, and the utility model with convenient maintenance can be operated by one person.
Description
The present invention is a kind of agriculture field machinery.
Machinery is cut the technology of returning crop stocks to the field, and has carried out for many years at home, and the drum shaft of this machinery and ground level arrange that blade is perpendicular to ground.When using in farm work with medium and small tractor, because ground is uneven, rugged, blade often screws among the earth, and blade bumps against with hard thing, causes mechanical oscillation excessive, and load increases the weight of.Very easily make blade abrasion or damage, it is frequent to change blade, and cost increases, and overall efficiency is not in full use; Simultaneously, because the restriction of this machine structural design resembles this crops that a line spacing is arranged of corn stalk, part blade idle running phenomenon will take place, increased mechanical idle work.
For solving the problem of the above existence, through repeatedly practising, constantly sum up, the present invention has drawn straw and has fallen automatically when cutting off.Can utilize the artificial control of pace, make the straw spiral enter this principle of cracker inner impact, that is to say the pulverizing main shaft is designed to perpendicular to ground, moving knife, the parallel ground of stationary knife, and make moving knife be right echelon spiral seniority among brothers and sisters to be fixed on the main shaft, parallel with stationary knife staggered, cut the also purpose in field of straw to reach.
Fig. 1 is the vertical cracker front view of returning crop stocks to the field.
Fig. 2 is the vertical cracker vertical view of returning crop stocks to the field.
Among the figure, 1～grain lifter, 2～left entry guards, 3～right entry guards, 4～framework, 5～backplate, 6～moving knife, 7～stationary knife, 8～main shaft, 9～conical tooth wheels, 10～bearing block, 11～turning cylinder, 12～belt pulley, 13～contact roller, 14～land wheel, 15～connecting rod, 16～strengthening frame, 17～tractor belt wheel.
The described vertical cracker of returning crop stocks to the field mainly is made up of power input system, crushing system, machine frame system, during work, be fixed on the tractor front portion by connecting rod (15), land wheel (14) is the heavy burden scroll wheel, tractor carries out farm work forward towards straw, to this machine belt pulley (12), the pressured bearing up pulley of the tightness of belt (13) is regulated by tractor belt wheel (17) input power.After the power input, drive power transmission shaft (11) by belt pulley (12) and make it to rotate, make the conical tooth wheels (9) that are installed on it make main shaft (8) do dead axle and rotate by engagement; Power transmission shaft (11) is fixing by two groups of bearing blocks (10), is the dextrorotation echelon on the main shaft (8) and is aligned in sequence with 10 moving knife (6), and the working face of moving knife (6) is a zigzag, is clamped on the knife rest by two iron plates.Every is the mutual angle between moving knife (6) 36 °, makes it to form the cutter hub that revolves of an integral body; Some groups of stationary knifes (7) are installed in the casing, parallel with moving knife (6) staggered, make straw pass through to insert standing grain device (1) left and right sides entry guards (2), (3), screw in the machine successively and pulverize, the also field of dishing out.
From drawings and Examples as can be seen, the vertical cracker of returning crop stocks to the field of the present invention, main shaft (8) and moving, stationary knife (6), (7) structural design meet inventive principle.Complete machine has that volume is little, in light weight, easy to maintenance, cutter life is long, cheap, efficient is high, and one man operation's advantage has importantly been avoided blade to screw in the unfavorable factor that earth brought and used wide.
The vertical cracker of returning crop stocks to the field that design principle according to the present invention designs is not limited to the above embodiment that says.
Claims (2)
1, a kind of vertical cracker of returning crop stocks to the field, mainly by the power input system, crushing system, machine frame system are formed, and it is characterized in that the main shaft 8 of crushing system is perpendicular to the ground, and moving knife 6 is parallel to the ground.
2,, it is characterized in that tower in the shape of a spiral being arranged on the main shaft 8 of moving knife 6 of crushing system according to the vertical cracker of returning crop stocks to the field of claim 1.Parallel staggered with stationary knife 7.
