Abstract
The utility model discloses a rotary cultivator chain drive casing combination, comprising a support arm, a cover cap and a cushion. The upper end of the support arm is connected to the support arm housing of the rotary cultivator, and the lower end is provided with a coulter shaft. The joint face between the cover cap and the support arm is provided with the cushion. The cover cap is fixed on the support arm with screws. The cover cap is made from thin plates. The peripheral height of the cover cap is 35-80mm. The peripheral height of the casting chain drive casing is replaced by that of the cover cap. When the chain is broken, only the cover cap will be damaged and the support arm will be maintained perfect. The rotary cultivator chain drive casing combination is advantageous in that maintenance cost is reduced; the structure is simple; the cost is low.
Description
Technical field
The utility model relates to a kind of agricultural machinery parts, and particularly a kind of and hand drags supporting rotovator chain drive box body combinations.
Background technology
Present and hand drags supporting rotovator model a lot, and this type rotovator mainly is to drive the coulter shaft rotation with chain drive, and it is simple in structure; Cost is low, because the farmland operation condition is relatively poor, the oil sealing of coulter shaft is fragile;, be not only can the lubricating oil in the chain drive case be spilt after the oil sealing of coulter shaft damages particularly, the more important thing is that slime water can get in the chain drive case at paddy-field-working; Cause chain wear to be exceedingly fast, it is elongated that chain is extended, and the chain phenomenon occurs climbing; The chain that fractures easily will damage the chain drive casing in case chain fractures, and is difficult to repair after foundry goods chain drive casing damages; Must change, maintenance cost is high, and some producers change the chain drive case into gear; With the defective of solution chain frangible, but gear-driven defective one is the cost height, the 2nd, after slime water gets into transmission case; Gear and bearing are worked in lapping liquid in fact, and the gear-bearing in several hours in the transmission case will all be scrapped, and maintenance cost is higher equally; Many users change gear into the chain drive case again, and this defective is because the service condition of farm work causes, thus at present and hand drag supporting rotovator chain drive casing on version, will improve.
Summary of the invention
The purpose of the utility model provides a kind of rotovator chain drive box body combinations.
The scheme of the utility model is: a kind of rotovator chain drive box body combinations, and by support arm, cover cap; Cushion is formed, and pad one cushion is fixed on cover cap on the support arm with screw on the composition surface of cover cap and support arm; Cover cap is processed with thin plate, and the periphery of cover cap highly is 35mm-80mm.
The utility model has the advantages that: can only cause the damage of cover cap when fractureing when chain is impaired, support arm can remain intact, and maintenance cost is low, and is simple in structure, and cost is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the combination sketch map of the utility model rotovator chain drive casing first embodiment
Fig. 2 is the combination sketch map of the utility model rotovator chain drive casing second embodiment
1. support arms, 2. cushions, 3. cover caps among the figure
Embodiment
Like Fig. 1, a kind of rotovator chain drive box body combinations shown in Figure 2, to form by support arm 1, cover cap 3 and cushion 2, the upper end of support arm 1 is propped up arm housing with rotovator and is connected; Coulter shaft is installed in the lower end, at composition surface pad one cushion 2 of cover cap 3 with support arm 1, with screw cover cap 3 is fixed on the support arm 1; Cover cap 3 usefulness thin plates are made, and the periphery of cover cap 3 is 35mm-80mm highly, is advisable with 60mm; Highly substitute the periphery height of foundry goods chain drive casing with the periphery of cover cap 3, can only cause the damage of cover cap 3 when fractureing when chain is impaired, support arm 1 can remain intact; Lowered maintenance cost, cover cap 3 can be made into one, also can cover cap 3 combinations be processed.
