Abstract

The utility model relates to a grasping conveyance chain, which belongs to the technical field of a chain. The utility model comprises an upper chain sheet (5), a lower chain sheet (7), and a chain shaft (6). The utility model is characterized in that the upper chain surface or the lower chain surface is fixed with a row of grasping teeth, the tooth space of every two adjacent grasping teeth (1, 3) is greater than or equal to the diameter D of a crop stalk which is grasped, and included angles beta of tooth roots of every two adjacent grasping teeth (1, 3) are less than or equal to 90 DEG. The utility model has the advantages of simple structure, ordered conveyance, convenience, reliability, high efficiency, and wide usage; furthermore, the utility model can realize the grasping conveyance of stalks, and the utility model is particularly suitable for the vegetal conveyance of stalk crops, such as, maize, sorghum, etc., and the operation of various agronomic crop harvesters and processors.

Description

A kind of clamping chain

Technical field

The utility model belongs to the driving chain technical field.

Background technology

Existing domestic corn straw harvesting machinery all is imitative wheat swather design, and it laterally is the fish scale shape to stalk is sidelong in machine one side, has brought inconvenience for like this carrying of stalk.Its chain is a spacing moving tooth conveying-type chain far away, and the clamping that can't finish stalk is carried even with the function of its neat lay in heaps.Also have kind of a conveying-type chain, its tooth depth is lower than the crops straw diameter, has spring leaf to hold up outward and send, and can not realize the clamping conveying function.

Summary of the invention

The purpose of this utility model provides a kind of clamping chain, it is simple in structure, can realize the clamping conveying of stalk, its conveying is orderly, convenient, reliable, efficient is high, purposes is wide, and the conveying that is particularly useful for plants such as corn, the thick stalk class of jowar crop reaches to be used on multiple kinds of crops reaping machine, processor.

Main technical schemes of the present utility model is: a kind of clamping chain, comprise chain sheet up and down, chain rivet, it is characterized in that above the chain or following chain is fixed with a row folding on unilateral and holds tooth, for realizing clamping, every adjacent two clamping tooth backlash are more than or equal to the diameter D that is held crops straw, tooth root angle β≤90 °, best β≤60 °, tooth root angle β is the angle between two bite tangent lines.

For ease of clamping, also be fixed with a row on another chain of above-mentioned chain is unilateral and push up up and down clamping tooth one to one with another toothrow, every two adjacent clamping tooth backlash are also more than or equal to the diameter D that is held crops straw, tooth root angle β≤90 °, preferably β≤60 °

In order simultaneously stalk to be fractureed in clamping and conveniently tiltedly to hold conveying, the retained part of two corresponding sides of the following clamping tooth that two limits of above-mentioned last clamping tooth are corresponding with its tooth top front and back on a length direction of chain are staggered to be good.

The chain sheet of the following clamping tooth that the chain sheet of above-mentioned last clamping tooth is corresponding with fixing its tooth top corresponds to good up and down one by one.When the chain sheet more in short-term, also can not be corresponding up and down, and be intersect fixing.

For making clamping more reliable, one side above-mentioned last clamping tooth is concave curved, one side the opposite of the following clamping tooth corresponding with it also is concave curved, the another side linear of last clamping tooth is one side the opposite of the following clamping tooth corresponding with it is linear.

For clamping tooth simple in structure, durable, the above-mentioned chain sheet corresponding with it is that integral type is preferable.Also can be split type.

For making clamping carry better effects if, adapt to the stalk clamping of thick straw section and carry, above-mentioned clamping chain can all be fixed with the corresponding up and down clamping tooth of a tooth top on the corresponding up and down chain sheet of a chain sheet.According to chain sheet length, but also on each chain sheet up and down correspondence all be fixed with a clamping tooth, also at interval on the chain sheet of one or several chain sheet up and down correspondence all be fixed with a clamping tooth.

For making clamping carry better effects if, above-mentioned clamping tooth ° is good with tooth root angle≤60.

The above-mentioned clamping tooth flank of tooth, parallel with the chain plate plane is good.The clamping flank of tooth also can be on-plane surface.

The utility model has the advantages that: it is simple in structure, can realize that the clamping of stalk is carried, and its conveying is orderly, convenient, reliable, efficient is high, purposes is wide; The conveying that is specially adapted to plants such as thick stalk class crop such as corn, jowar reaches to be used on multiple kinds of crops reaping machine, processor.

Be described further below in conjunction with embodiment, but not as to qualification of the present utility model.

Embodiment

Referring to Fig. 1, Fig. 2, Fig. 3,5 is the cochain sheet, 7 are following chain sheet, 6 is chain rivet, all be fixed with a row folding on the chain face about the chain and hold tooth, correspondence all is fixed with a clamping tooth up and down on the chain sheet of a chain sheet, and the last clamping tooth 1 of tooth top correspondence and two corresponding sides retaining parts of following clamping tooth 2 front and back on length direction of chain are the formula that staggers and arrange; One side of last clamping tooth 1 is concave curved (this limit is towards direction of advance), one side the opposite of the following clamping tooth 2 corresponding with it also is concave curved, the another side of last clamping tooth 1 is a linear, one side the opposite of the following clamping tooth 2 corresponding with it is linear; The flank of tooth such as clamping

tooth

1,2,3,4 are the plane, and are connected 5,7 plane parallel; Clamping tooth 1, the 2 chain sheets corresponding with it can be integral type; Clamping tooth backlash is all greater than the diameter D that is held the material stalk (stalk is as the criterion to hold down) up and down, as when being used for maize straw and pinching, generally getting D is 26～28mm.

Referring to Fig. 4, the corresponding equal Yangtze River Delta tooth of the tooth of clamping up and down (the tooth limit can be straight line or concave curved), last lower tooth corresponding sides are relative up and down, not staggered positions.

Above tooth root angle β≤90 °, best β≤60 °.Tooth root angle β is the angle between two bite tangent lines, shown in β among the figure 1, β 2, β 3; Clamping tooth backlash 〉=D, as shown in the figure.

In actual applications, more reliable for clamping is carried, also can be on toothrow, below or the outside grain lifting rod of establishing of tooth.
