Abstract

A novel rolling harrow belongs to the technical field of agricultural implements and aims to provide a novel rolling harrow which can not only crush clods but also level the land during the harrowing process. The technical key point is that the rolling harrow is provided with a harrow frame (2), and a roller (9) which is mounted in parallel below the harrow frame and provided with flaky rectangular harrow teeth; and a drag harrow (7) is connected backwards on a bracket (11) below both sides of the harrow frame. Since the drag harrow is connected below the rear part of the harrow frame, the clods are shattered under the action of the drag harrow after the roller at the front of the drag harrow crushes the clods, so as to facilitate direct cultivation of crops.

Description

Novel cylinder harrow

Technical field

The utility model relates to a kind of farm implements, particularly a kind of improved novel cylinder harrow.

Background technology

Chinese patent 98217423 discloses a kind of paddy field roller harrow, and this roller harrow is rolled to roll with rake teeth and formed by the rake frame, rolls and rolls to cylindrical, and rake teeth is the sheet rectangle, and rake teeth is distributed on and rolls on the round as a ball cylinder; Two roll and roll respectively the bottom of being located at the rake frame by axle, bearing or axle sleeve side by side.This rake has been owing to adopted the sheet rectangle rake teeth of band groove, so the intensity of rake teeth, rigidity are higher, is fit to the operation in hard field piece such as wheatland, rape field, green manure field and deep water mud field, rolls in the operation not roll saggingly, and it is strong to rub broken power.But it is relatively poor to roll the ground flat degree of harrowing through the sheet rectangle rake teeth of roller harrow, is unfavorable for crop planting.

Summary of the invention

The purpose of this utility model provides a kind of ploughing at rake can either grating soil block, the novel cylinder harrow that can level land again in the process.

Its technical scheme is: a kind of novel cylinder harrow, and comprise the rake frame and be installed in the rolling of strap shape rectangle rake teeth of harrowing the frame below side by side and roll, it is characterized in that: connect a planker on the support of the down either side of described rake frame backward.

Its technique effect is: owing to connect a planker in the back lower place of rake frame, so after rolling of its front rolled the soil block grating, under the effect of planker, again the soil block of grating is rubbed broken smooth, thereby help the direct plantations of crops.

Fig. 2 is the planform schematic diagram of planker.

Embodiment

As shown in Figure 1, novel cylinder harrow comprises the rake frame and is installed in the rolling of strap shape rectangle rake teeth 10 of harrowing the frame below side by side and rolls 9.Connect a planker 7 backward on the support 11 of the down either side of rake frame 2.That is: on an affixed respectively follower head on the support of down either side of rake frame, be provided with the connecting rod 4 of hook, the both sides, front of planker connect respectively a termination offer collude groove win 8 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 of planker.

The front of planker and left and right both sides both can prevent splashing of muddy water all to the upper overturning (see figure 2) in the process of farming, can carry out effectively smooth to rolling the ground that rolls across simultaneously again.

Planker 7 is identical with the axial length of rake frame.

The middle position, back of planker is provided with hook 12, this hook can be connected by the hook 1 that is provided with on rope and the rake frame girder, with planker upwards turnover be hooked on the rake frame ridge enters or withdraws from the field smoothly so that roller harrow is ascended, and also is convenient to roller harrow and on the way walks.

The hook that the planker back is provided with also can be used as the guide pile of cushion strut 5.The lower end of cushion strut is and the tubulose of hook coupling socket that the bottom of cushion strut also is provided with the three piece supporting legs 6 parallel with its lower end.The lower end of cushion strut is plugged on the outer rim of hook, and three supporting legs on it can play the effect of supporting and keeping cushion strut balance.

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.

Claims

1, a kind of novel cylinder harrow comprises the rake frame and is installed in the rolling of strap shape rectangle rake teeth of harrowing the frame below side by side and rolls, and it is characterized in that: connect a planker (7) on the support of the down either side of described rake frame (2) backward.

2, a kind of novel cylinder harrow according to claim 1 is characterized in that: the front of described planker (7) and left and right both sides are all to upper overturning.

3, a kind of novel cylinder harrow according to claim 1 and 2 is characterized in that: described planker (7) is identical with the length of rake frame.

4, a kind of novel cylinder harrow according to claim 1 is characterized in that: the middle position, back of described planker (7) is provided with hook (12).
