Abstract

A crop plot experiment furrow opener is suitable for crop plot experiment furrowing and has low cost, light weight and practicality without needing power traction. The furrow opener includes a base, a ploughshare, a paddling device, a pull rod and a handle, wherein the base comprises a soleplate, a trigonocephalia and two vertical plates provided with vertical grooves; the soleplate is slightly in a bow shape and is connected with the trigonocephalia at the front end, and the outer wall of the trigonocephalia clings to the inner wall of the ploughshare; a short vertical plate is fixed at the rear end of the soleplate, and a long vertical plate is fixed at the front middle part of the soleplate; the ploughshare is sleeved outside the trigonocephalia, one end of an iron wire is tied up in an ostiole which is arranged over the ploughshare, and the other end is connected with the vertical groove of the long vertical plate; the pull rod is fixed on the vertical grooves of the two vertical plates by bolts, and the upper position and the lower position of the pull rod can be adjusted; the paddling device comprises a measuring scale and a paddling cone, wherein the measuring scale is fixed on the vertical groove of the long vertical plate by the bolt and is vertical to the long vertical plate; the paddling cone consists of two pieces of iron sheets, one of the iron sheets is of a V shape at the front end, and the other iron sheet is of a rectangle at the rear end, and the two iron sheets are blocked on the measuring scale by bolts.

Description

Crops small plot experiment plough

Technical field

The utility model relates to a kind of crops small plot experiment plough.

Background technology

Before the eighties in last century, the method that China's crops small plot experiment mostly adopts spud trench digging hand point seed or removes seed is sowed, and the spud trench digging requires great effort, deep mixed, and effect is low.After the eighties in last century, China part scientific research institutions are from the wheat small plot experiment sower of external import, but program request (selective nursery), drilling (test such as product ratio), and have multiple functions such as trench digging, seeding down, earthing, operating efficiency is higher.But still there is a following problem: the one, need the mating power towage, relatively heavier, cost is higher, and (being import) costs an arm and a leg; The 2nd, behind seeding operation, the sower tire can be depressed deep trace, makes the farmland very uneven, and when causing the nonirrigated farmland small plot experiment rainfall forming runoff in breeding time, rainwater then collects in tire and depresses in the deep trace, forms tangible soil moisture difference; In water ground small plot experiment then since tire depress deep vestige and bring pour water inhomogeneous.The 3rd, the maximum of small plot experiment sowing width has only six row (the sowing width only has 1.2m), strengthen the sub-district area, and unique method is the length of sub-district sowing of can only extending, and can form the difference of soil nutrient and moisture in the sub-district like this.

Summary of the invention

The utility model purpose is the deficiency that overcomes above-mentioned prior art, low, the light practicality of a kind of cost is provided, does not need the crops small plot experiment plough of power traction.

The utility model comprises base, ploughshare, the device that paddles, pull bar and handle; Base comprises base plate, trigonocephalia and has two risers of vertical slot, and it is arc that base plate slightly is, its preceding termination trigonocephalia, and the trigonocephalia outer wall is close to the inwall of ploughshare; Short riser is fixed on the rear end of base plate, and long riser is fixed on the front middle part of base plate; Ploughshare is sleeved on outside the trigonocephalia, and iron wire one end is fastened directly over ploughshare in the aperture, and the other end is connected with vertical slot on the long riser; Pull bar is by on the vertical slot that is bolted to two risers, and upper-lower position is adjustable; The device that paddles comprises scale and draws awl, and scale is by being bolted on the vertical slot on the long riser, and vertical with long riser; Draw awl and be made up of two iron plates, one of front end is the V font, and one of rear end is a rectangle, and two iron plates, can slide along scale on scale by bolt card.2 of the rear end of base plate and share beaks are on same horizontal line, and it is arc that the base plate mid portion slightly is, to reduce soil resistance.

The utility model is suitable for crops small plot experiment trench digging.On the basis that the small plot experiment length and width are determined, at first adjust the position of pull bar, to determine sowing depth at vertical slot.Adjusting drawing on the scale according to line-spacing then bores, haul down along ground, sub-district ridge at sideline, sub-district precontract 15cm place, get to ploughshare and go out about 10cm place, sideline, sub-district, will leave the kind cunette of desired depth like this, drawing the line that awl one side can form the required trench digging of next line position simultaneously.Go out sub-district two position Duan Jun of about 10cm at sideline, sub-district precontract 15cm and ploughshare and do not remove seed or some seed.

The utility model does not need supporting any power traction, but as long as a people is pulling on down just operation of walking backward.Product uses light flexibly, and operating cost is low, and the line-spacing of Different Crop, sowing depth can be adjusted.Through using in wheat program request (offspring's selective nursery), drilling (tests such as product ratio, fertilizer), soybean, millet, cotton, seeding corn and other crops, effect is all more satisfactory, compare with traditional artificial spud ditching operation, can significantly improve 4-6 times of effects, and trench digging degree of depth unanimity; Having overcome external import plant planter simultaneously needs mating power, pressure ground, the fixing weak point of sub-district sowing width, and simple in structure, and production cost is low.

Fig. 2 is the utility model base and the apparatus structure schematic diagram that paddles.

Among the figure: 1, handrail, 2, pull bar, 3,4, bolt, 5, short riser, 6, long riser, 7,8, vertical slot, 9, base plate, 10, iron wire, 11, aperture, 12, ploughshare, 13, scale, 14, draw and bore, 15, screw, 16, trigonocephalia.

Embodiment

The trigonocephalia 16 of base plate 9, short riser 5 and long riser 6, base plate 9 front ends all adopts ironcasting, but one-step casting is finished.

The degree of depth of trench digging is regulated by pull bar 2 position in the vertical slot 8 on short riser 5, perhaps regulates by adjusting pull bar 2 position in the vertical slot 7 on long riser 6.Pull bar 2 vertical slot 7 metas on long riser 6 deposit move then ditch shallow, on to move then trench digging dark.Pull bar 2 position in the vertical slot 8 on short riser 5 moves down that then trench digging is dark, on move then ditch shallow.

Small pieces trench digging on the ground is also very suitable behind the house before for small pieces farmland below 600-800 square metres and room for the utility model, and operational procedure is identical with aforesaid small plot experiment trench digging, determine sowing depth and line-spacing after, ditching along rand gets final product.
