Abstract

The invention relates to a novel rolling harrow belonging to the technical field of farm tools. The invention aims at providing a novel rolling harrow which can crush clods and keep the rolling harrow from jumping during harrowing and can level the land, and can walk on a tractor road with minor vibration and does not cause damage to the top of a support block. The technical points of the novel rolling harrow are as follows: a channel iron (4) is respectively welded on the top end of two neighboring rings of flaky harrow teeth (3) at the middle of the cylindrical surface of a roll (2), a tension sleeve (5) is welded between the two neighboring rings of the channel iron; a drag harrow (6) is arranged at the rear of a rectangular harrow frame. As the channel iron is welded on the top end of the two neighboring rings of flaky harrow teeth, the function of crushing earth and flexibility of the novel rolling harrow can be strengthened. As the tension sleeve is welded between the two neighboring rings of the channel iron, the rolling harrow can keep stable in the harrowing process, the channel iron is protected from being damaged when walking on the tractor road and vibration can be reduced, and the drag harrow arranged at the rear of the harrow frame can prevent the earth from splashing in tillage and level the rolled land at the same time.

Description

Novel cylinder harrow

Technical field

The present invention relates to a kind of farm implements, particularly a kind of novel cylinder harrow.

Background technology

Chinese patent 200620075737.0 discloses the cultivated formula roller harrow of a kind of seat; This roller harrow by rectangle rake frame be installed in side by side below the rectangle rake frame two cylindrical roll to roll form; Cylindrical roll to roll be uniformly distributed with the sheet rake teeth, roll round as a ball cylinder in the middle of same footpath upwards be uniformly distributed with bracer, this roller harrow is through setting up bracer rolling to roll; Roll the resistance that advances though reduced to roll, strengthened to roll and rolled anti-skidding function.But, there is bigger spacing between the adjacent bracer that round as a ball cylinder directly makes progress owing to be arranged on to roll, to roll beating of rolling in the process more violent so plough at rake, not only shakes greatlyyer when on wide paths for tractors in the countryside, walking, but also can cause damage to the top of bracer.Simultaneously, it is also relatively poor to roll the ground flat degree of harrowing through this roller harrow.

Summary of the invention

The purpose of this invention is to provide a kind of can ploughing in the process at rake can the grating soil block, and roller harrow is not beated again, can also level land simultaneously; The vibrations of on wide paths for tractors in the countryside, walking are less, can not cause the novel cylinder harrow of damage to the top of bracer.

Its technical scheme is: a kind of novel cylinder harrow; Comprise that rectangle rake frame and two cylindrical rolling that are installed in rectangle rake frame below side by side roll, cylindrical roll to roll be uniformly distributed with the sheet rake teeth, roll in the middle of the round as a ball cylinder adjacent two enclose the sheet rake teeths the top; Be welded with channel respectively; Be welded with cranse between one side of two adjacent ring recess iron, the rear of rectangle rake frame is provided with planker, and it is characterized in that: an affixed respectively follower head is provided with the connecting rod of hook on the support of the down either side of said rake frame; The both sides, front of planker connect a termination respectively and offer and collude winning in succession of groove, and the hook coupling of colluding on groove and the link end on this is won in succession articulates.

Channel is identical with the axial length of sheet rake teeth, and radial width is identical.

Planker is identical with rectangle rake frame width, and its front and left and right both sides are all to upper overturning.

Place, middle position, planker rear portion is provided with colludes button.

Its technique effect is: the top rolling two adjacent circle sheet rake teeths of round as a ball cylinder centre is welded with channel respectively; Both increased and rolled the intensity of rolling; Increased again and rolled the weight of rolling; Make to roll to roll at the initial stage of farming to have strengthened broken function and flexibility to earth, it rubs flat better effects if to stepping on of earth is broken; Later stage in farming has been played anti-senkung again.Between a side of two adjacent ring recess iron, be welded with cranse, be equivalent to roll to roll disposed road wheel, roller harrow is ploughed at rake not only played balance, effect stably in the process to two; And when on wide paths for tractors in the countryside, walking, channel is not directly contacted with ground with the sheet rake teeth, and both protected sheet rake teeth and channel injury-free, reduced vibrations again; The rear of rectangle rake frame is provided with whole the planker that equates with its width, and the splashing of earth when both effectively having prevented the arable land can be carried out smoothly to rolling ground after rolling again simultaneously, makes that the flatness on ground is better.

Fig. 2 is a channel planform sketch map;

Fig. 3 is the structural representation that removes behind the cushion strut.

Embodiment

As shown in Figure 1, novel cylinder harrow comprises that rectangle rake frame 1 and two cylindrical rolling that are installed in rectangle rake frame below side by side roll 2, cylindrical roll to roll be uniformly distributed with sheet rake teeth 3, the main beam rear end of rectangle rake frame is by the cushions support bar 8 of pole connection.Roll the top of two adjacent circle sheet rake teeths of round as a ball cylinder centre, be welded with channel 4 respectively, be welded with cranse 5 between the side of two adjacent ring recess iron.The rear of rectangle rake frame is provided with planker 6.That is: an affixed respectively follower head is provided with the connecting rod 12 of hook on the support 11 of rake frame down either side; The both sides, front of planker connect respectively a termination offer collude groove win 61 in succession; The hook coupling of colluding on groove and the link end on this is won in succession articulates, and is convenient to the loading and unloading to planker.

Channel 4 is identical with the axial length of sheet rake teeth 3, and radial width is identical.

Planker 6 is identical with the axial length of rectangle rake frame, and its front and left and right both sides are all to upper overturning.Such structure both can prevent splashing of muddy water in the process of farming, can carry out effectively smooth to rolling the ground that rolls across simultaneously again.

Place, middle position, planker rear portion is provided with colludes button 7.Collude button and constitute the planform that both sides are flat, swell the middle part by the round bar bending.This colludes button and both can cooperate with the hook 14 that is provided with on the rake frame girder, with the planker back upwards after the turnover, through rope it is hooked on and harrows on the frame, is convenient to the roller harrow ridge of ascending, and gets into or withdraw from the field smoothly, also is convenient to roller harrow and on the way walks.Simultaneously, this colludes the guide pile that button also can be used as cushions support bar 8.The bottom of cushions support bar is and colludes the tubulose of the protuberance coupling grafting of smashing a position, so that the plug of cushions support bar.The top of cushions support bar also is provided with adjustment hole 81; This adjustment hole cooperates with pole 13 on being plugged on rake frame girder; Can adjust the planker particularly back of planker and the distance on ground so that roller harrow roll roll soil block in, ground is carried out effectively smooth.

The anterior level of rectangle rake frame is installed and is connected A-frame, and the A-frame front end is provided with the connector that cooperates with the hand tractor frame.
