Abstract
The present invention discloses a weeding and soil loosening machine. The machine comprises a mobile rack, a land wheel axle, an upper pull rod, a middle support, a transmission spocket, a rotary hoe assembly, a transmission chain, a lower pull rod and a drive spocket, wherein two ends of the transmission spocket is connected in a rotating manner with profiling shovels, the rotary hoe assembly comprises eight pin-teeth hoe disks, the difference between two connected pin-teeth hoe disks is 90 degrees, each pin-teeth hoe disk is provided with eight pin teeth which are arranged in a circumferential direction, outer tips of the pin teenth are bulb-shaped, the radius of the bulb is 4.5 mm, a front inclination angle between a pin tooth tip arc and a tangential direction is 35 degrees, and an included angle between the pin tooth tip arc and a radial direction center line is 65 degrees. The pin-teeth hoe disks do not carry soil blocks or rocks during working, phenomena that soil buries young plants and pin teeth twine straws and weed are avoided, and the weeding and soil loosening machine has the advantages of being high in weeding rate and low in seedling damage rate.
Description
Technical field
The present invention relates to agricultural mechanical field, particularly relate to a kind of weed and loose soil machine.
Background technology
Northern China dry farming area is in soybean in field whole production process Mechanization Technique, and extirpator is important field management facility, and it is reduce fertilizer and pesticide to the pollution to crops, produces better pollution-free food and has made important contribution.But, key operation parts rotary hoe assembly on existing soybean extirpator, due to its structural design and parameter determination Problems existing, often carry soil block, stone during the dish operation of pin tooth hoe secretly, soil buries crop young plant and tooth of hoeing up weeds is wound around the phenomenon such as stalk and weeds, effect of hoeing up weeds is caused to reduce, seedling-damaging ratio increases, and operating efficiency reduces.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, a kind of weed and loose soil machine is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of weed and loose soil machine, comprise movable machine frame, land axle, upper connecting rod, intermediate support, drive sprocket, rotary hoe assembly, driving chain, lower link and drive sprocket, described drive sprocket is installed on the square shaft of rotary hoe assembly, described drive sprocket is installed on land axle, the pin tooth hoe disc spins of rotary hoe assembly is driven by described driving chain, the two ends of described drive sprocket are rotatably connected to profiling shovel, described rotary hoe assembly comprises eight pin tooth hoe dishes, and the pin tooth of two the pin tooth hoe dishes that are connected differs 90 °; Described pin tooth hoe dish is provided with eight pin teeth, circumferentially uniform, the tip, outer end of described pin tooth is bulb shape, and Probe-radius is 4.5mm, the top rake of pin tooth tip portion arc and tangential direction is 35 °, and the angle between pin tooth tip portion arc and radial centre lines is 65 °.
Further, the front end of described movable machine frame is connected on Tractor Driving Axle housing, and rear end is hinged on hanger bracket, and like this, between seedling, weed and loose soil machine and tractor become to be fixedly hinged state, meets the stability requirement of the horizontal operation of rotary hoe assembly.
The invention has the beneficial effects as follows:
Do not carry soil block and stone secretly during pin tooth hoe dish operation in the present invention, avoid that soil buries crop young plant, pin tooth is wound around the phenomenon such as stalk and weeds, there is the advantage that the rate of hoeing up weeds is high, seedling-damaging ratio is low.
Accompanying drawing explanation
Fig. 1 is vertical view of the present invention.
Fig. 2 is end view of the present invention.
Fig. 3 is the structural representation of pin tooth hoe dish in the present invention.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figures 1 to 3, a kind of weed and loose soil machine, comprise movable machine frame 1, land axle 2, upper connecting rod 3, intermediate support 4, drive sprocket 6, rotary hoe assembly 7, driving chain 8, lower link 9 and drive sprocket 10, described drive sprocket 6 is installed on the square shaft of rotary hoe assembly 7, described drive sprocket 10 is installed on land axle 2, driven the pin tooth hoe disc spins of rotary hoe assembly 7 by described driving chain 8, the two ends of described drive sprocket 10 are rotatably connected to profiling shovel 5.Described rotary hoe assembly 7 comprises eight pin tooth hoe dishes, and the pin tooth of two the pin tooth hoe dishes that are connected differs 90 °; Described pin tooth hoe dish is provided with eight pin teeth, circumferentially uniform, the tip, outer end of described pin tooth is bulb shape, and Probe-radius is 4.5mm, the top rake of pin tooth tip portion arc and tangential direction is 35 °, and the angle between pin tooth tip portion arc and radial centre lines is 65 °.
Further, the front end of described movable machine frame 1 is connected on Tractor Driving Axle housing, and rear end is hinged on hanger bracket, and like this, between seedling, weed and loose soil machine and tractor become to be fixedly hinged state, meet the stability requirement of the horizontal operation of rotary hoe assembly 7.
The operation principle of the present embodiment is:
Pin tooth hoe dish is under the driving of land axle 2, and pin tooth thrusts soil with certain speed, has a Relative sliding at depth capacity place, when leaving soil and being unearthed, is upwards provoked by soil again with certain speed; Utilize this movement characteristic of pin tooth, make it while hack, stir soil, serve the effect of weed eradication, thinning and stirring.Do not carry soil block and stone secretly during the dish operation of pin tooth hoe, avoid soil and bury crop young plant, phenomenon such as the winding of pin tooth stalk and weeds etc., rate of hoeing up weeds is high, and seedling-damaging ratio is low, realizes soybean yield-increasing 8% ~ 10%.
