Abstract

The utility model discloses a seeding drill with an improved structure. The utility model mainly comprises a drill body 2, a land wheel 1 which is arranged at the front end of the drill body, a seed and fertilizer barn 3 which is arranged at the upper part of the drill body, a drill foot 4, a pressing wheel 5, and a handle 10. The utility model is characterized in that a chainwheel 6 which is assembled at one side of the drill body and is coaxial with the land wheel 1 is matched with a chainwheel 9 which is arranged on an intermediate shaft 8 which is arranged at the lower side of the seed and fertilizer barn 3 through a chain 7 to drive the intermediate shaft 8. A gear 11 which is arranged on the intermediate shaft is engaged with a gear 12 which is arranged on a seed and fertilizer wheel shaft 13 to drive the seed and fertilizer wheel shaft 13, and a seed and fertilizer wheel 14 is driven to rotate. The utility model has the advantages that the utility model can efficiently protect the drive of the chain to prevent the chain from tangling by a foreign matter such as a wheat straw not to seed when a cornfield is interplanted. The planting distance for seeding can be changed by that a gear with different teeth is changed.

Description

A kind of seeding plough that improves structure

The utility model relates to agricultural machinery, particularly a kind of seeding plough that improves structure.

Seeding plough in the prior art had varied, and the applicant once applied for the Chinese patent of multi-functional seeding plough, the patent No. 96227471.2 in 96 years.Through the enforcement in 2 years, the disadvantages affect that aforementioned patent exists use, mainly be that driving chain is tangled by foreign material such as wheat straws easily and influences normal seeding operation.Therefore having proposed improved plan, also is the purpose of this utility model.

The purpose of this utility model provides a kind of seeding plough that improves structure, to overcome the problem that original seeding plough exists.

The purpose of this utility model realizes according to structure described below, this improves the seeding plough of structure, mainly comprise an animal-drawn seed plough body 2, the land wheel 1 of an animal-drawn seed plough body front end, the seed manure storehouse 3 on an animal-drawn seed plough body top, an animal-drawn seed plough pin 4, press wheel 5, handle 10, it is characterized in that cooperating transmission jackshaft 8 by the sprocket wheel 9 on the jackshaft 8 of chain 7 below seed manure storehouse 3 with land wheel 1 coaxial sprocket wheel 6 near the assembling of an animal-drawn seed plough body one side, gear 11 on the jackshaft 8, the gear 12 engaged transmission seed manure wheel shafts 13 on gear 11 and the seed manure wheel shaft 13 drive seed manure wheel 14 and rotate.

The utility model has the advantages that chain can be protected effectively, and, increased jackshaft and one group of travelling gear, by adjusting the gear ratio of gear pair, can realize the different rotating speeds of seeding wheel, further increase the sowing spacing in the rows and the scope of application of seeding plough.Be fixed on the gripper shoe of relevant position on an animal-drawn seed plough body 2 support zone being provided with of land axle and jackshaft and seed manure wheel shaft, in order to regulate the degree of tightness of chain.Chain and sprocket wheel are arranged near an animal-drawn seed plough body one side, and a guard shield that is fixed on an animal-drawn seed plough body 2 can be set easily, when preventing in wheatland interplanting corn, are tangled by bundle things such as wheat straws and influence use.

The following drawings explanation, accompanying drawing 1 is a front view of the present utility model, accompanying drawing 2 is vertical views of accompanying drawing 1.The code designation of each sequence number in the accompanying drawings is: 1, land wheel, 2, an animal-drawn seed plough body, 3, the seed manure storehouse, 4, an animal-drawn seed plough pin, 5, press wheel, 6, sprocket wheel, 7, chain, 8, jackshaft, 9, sprocket wheel, 10, handle, 11,12, gear, 13, the seed manure wheel shaft, 14, the seed manure wheel, 15,16, gripper shoe.

Describe structure of the present utility model in detail below in conjunction with the embodiment in the accompanying drawing.With reference to the seeding plough of the improvement structure of the embodiment among attached Fig. 1 and 2, mainly comprise an animal-drawn seed plough body 2 of frame-type, an animal-drawn seed plough body front end is a land wheel 1.An animal-drawn seed plough body top is seed manure storehouse 3, and there is a dividing plate centre in seed manure storehouse 3, and seed and fertilizer are separated.After slightly leaning on below the seed manure storehouse an animal-drawn seed plough pin 4 and subsequent press wheel 5.The rear portion of an animal-drawn seed plough body is a handle 10.Coaxial near sprocket wheel 6 of an animal-drawn seed plough body one side assembling with land wheel 1, this sprocket wheel 6 cooperates transmission jackshaft 8 by the sprocket wheel 9 on the jackshaft 8 of chain 7 below seed manure storehouse 3.Opposite side on the jackshaft 8 is a gear 11, and the gear 12 engaged transmission seed manure wheel shafts 13 on gear 11 and the seed manure wheel shaft 13 drive the seed manure wheel 14 that is fixed on the seed manure wheel shaft and rotate.The tightness of chain when adjusting transmission is fixed on the gripper shoe 15 and 16 of relevant position on an animal-drawn seed plough body 2 support zone being provided with of land axle and jackshaft and seed manure wheel shaft, in order to regulate the degree of tightness of chain.As shown in FIG., gripper shoe 15 supports land axle 1, and gripper shoe 16 is slightly long, supports jackshaft and seed manure wheel shaft simultaneously.This an animal-drawn seed plough can be used as interplant drill and uses, and puts into seed and chemical fertilizer in the seed manure storehouse respectively, can sow, and spacing in the rows can be as the method for adjustment of the multifunctional sowing an animal-drawn seed plough of the patent No. 96227471.2, also can realize the variation of spacing in the rows by gear changing 12 and 11 more.Also can sow separately or broadcast to fertilize separately with this an animal-drawn seed plough.Can adapt to various crop seed sowing, program request and impose operations such as chemical fertilizer.For convenience of description, the protective cover of do not draw among the figure sprocket wheel and chain.
