Abstract

The utility model discloses a spiral type rolling rake which is an agricultural harrowing implement exclusively used by matched with a one-way share plough. The spiral type rolling rake is composed of components, such as a soil crashing device, a harrow frame, a depth adjuster, an articulated beam, etc. The tilling and the harrowing operations of a farmland can be finished once. The utility model has the advantages of light weight, simple structure, low cost, etc., and the utility model is an agricultural implement which is easy to generalize.

Description

Spiral type rolling rake

The utility model is a kind of farm machinery, and the supporting use of special-purpose and unidirectional mouldboard plow is carried out the farmland and ploughed the rake operation.

Existing furrowing and harrowing machine tool, as " tilling and raking plough ", " mouldboard plow adds round disk rake " though can both plough the rake operation simultaneously." but tilling and raking plough " complex structure, cost of manufacture are higher, can excessively destroy soil aggregate and cause unnecessary power consumption in ploughing the rake operation process." mouldboard plow adds round disk rake " can cause shortcomings such as tractor adhesive force deficiency, power can not make full use of in cultivated rake process.Above-mentioned shortcoming directly affects applying of these farm machinery.

The purpose of this utility model is to manufacture and design a kind of can finishing simultaneously to plough the new-type furrowing and harrowing machine tool of harrowing operation.It promptly has the machinery chopping soil block of raking the soil level, shakeouts the function of soil, and structure is comparatively simple, and can reduce power consumption.

Describe its each modular construction and function in detail below in conjunction with accompanying drawing. Clod-crusher (1) turns to " spring " shape by bar reinforcement and forms as shown in Figure 1. The cross section of bar reinforcement is triangle or ellipse. The high about 20mm of triangle. The base is about 7mm; Or the about 10mm of oval major semiaxis, clod-crusher (1) " spring " diameter 30cm, the about 6cm of " spring " pitch. " spring " whenever detours 480 ° from initial end and welds a skeleton (4) on hollow shaft (2).

The bar reinforcement two ends are fixed on the hollow shaft (2) as shown in Figure 2, and the axle sleeve (3) of hollow shaft (2) passes through bolt with rake frame (5).Be fixed with a web beam (6) on the rake frame (5), crossbeam (6) is gone up vertical fixing depth adjustment seat (7).

Depth adjustment seat (7) and horizontal adjustment seat (9) go up each and vertically are arranged with 4 adjustment holes (8), (10) as shown in Figure 3, articulate pin (11) on the beam (18) and pass the height that different a pair of adjustment holes (8), (10) can be regulated whole rake.As shown in Figure 4, difference rake that so just can adapted soil is dark.

Articulate as shown in Figure 5 on beam (18) inclined-plane, top and to be fixed with a power regulating spring steel disc (19) with screw and just in time to compress, damage with the working resistance that prevents to increase suddenly and harrow frame (5) and clod-crusher (1) with the one side that depth adjustment seat (7) (angle steel) punch.

Harrow frame (5) as shown in Figure 6 a level(l)ing mechanism is arranged, make by differential screw mechanism, thick button nut (12) is fixed on the rake frame (5), thin button nut (13) is vertically welded on the horizontal adjustment seat (9), because adjustment hole (8) ovalize, pin (11) has a free gap in adjustment hole (8).As shown in Figure 7 when rotating horizontal release handle (14) just can so that horizontal adjustment seat (9) with respect to depth adjustment seat (7) parallel sliding, thereby trace changes rake frame (5) and the relative tilt angle that articulates beam (18), also promptly regulates rake frame (5) and ground surface angle.

Crossbeam (6) is gone up each a vertical socket (15), (16) of being welded with horizontal adjustment seat (9) as shown in Figure 6, inserts a pin (17) and just can play the directed slip effect of reinforcing.

To articulate the crooked angle of beam (18) other end as shown in Figure 1, angular range is 65 °-95 °, to adapt to and being connected of different structure mouldboard plow.Sweep is fixedlyed connected with the mouldboard plow frame by U type card (20).Sweep top and articulate and be welded with rinforcement bar (21) between the beam (18).

The fabric width of spirally rolling rake should be greater than about working width 15cm as shown in Figure 2.For the multishare plough of working width broad, a spirally rolling rake can be set at each ploughshare rear portion.Rake frame (5) is a little more than mouldboard plow frame height.

The spirally rolling rake is compared following advantage with existing furrowing and harrowing machine tool: because being rigidly connected of it and mouldboard plow, weight by mouldboard plow can alleviate rake body own wt, obtain the required pressure at right angle of raking the soil level simultaneously, it rollably shreds soil block in operation process, avoid " tilling and raking plough " overcrushing soil aggregate and unnecessary power consumption, the tractor adhesive force deficiency of also having avoided " mouldboard plow adds round disk rake " dependence deadweight cutting and crushing soil to bring.The spirally rolling rake utilizes the broken soil block of reinforcing bar that " gathering around soil " phenomenon can not take place.Weeds, the plant roots and stems that can will clamp-on in the clod-crusher (1) when operation are disposed, and are transported to the face of land or ditch dug with a plow.

The spirally rolling rake is simpler from heavy and light, structure, can be easily and the supporting use of various mouldboard plows, and be a kind of farm machinery that are easy to promote.
