[patent documentation 1] (Japan) spy opens the 2001-238518 communique
In patent documentation 1, be formed with the recessed dark recess of whole pin that is used to make carrier chain at the peripheral part of driven rotary body, the trend that therefore exists the external diameter of driven rotary body to increase.But in the harvesting pre-treatment portion of combine, the space of stalks conveying apparatus is limited, when the external diameter of driven rotary body is big, is difficult to be configured.At this moment,, make whole pathization though can consider driven rotary body is replaced by the roller shape rotary body that does not possess recess at peripheral part,, the inlet that driven rotary body gets into carrier chain diminishes, and causes carrier chain to tilt with respect to driven rotary body easily.
The utility model content
Therefore, driven rotary body and the combine used of the purpose of the utility model stalks conveying apparatus that is to provide a kind of integral miniaturization and carrier chain to be difficult to tilt.
First feature structure of the driven rotary body that the stalks conveying apparatus of the utility model is used is; In stalks conveying apparatus; This driven rotary body and drive sprocket one roll set hang with carrier chain and receive the revolving force of said drive sprocket and rotate; Being formed with a plurality of pin and cross sections of taking in said carrier chain at the peripheral part of driven rotary body is circular-arc recess; Said recess forms, and under the state in said pin is accommodated in this recess, the center that is centered close to driven rotary body of said pin is the round outside of going up or being positioned at this outside circle, the peripheral part outside partly outside center and the said recess of process.
The pin of carrier chain is recessed to be formed in the recess of driven rotary body peripheral part, and driven rotary body receives the revolving force of carrier chain and rotates from carrier chain.At this; The recess of driven rotary body forms; Under the state in the pin of carrier chain is accommodated in the recess of driven rotary body; The center that is centered close to driven rotary body of the pin of carrier chain is the round outside of going up or being positioned at this outside circle, the peripheral part outside partly outside center and the process recess of driven rotary body, and therefore, the peripheral part with respect to driven rotary body over half of pin is given prominence to.That is, it is roughly the same with the diameter of the pitch circle of the center process of the pin of the carrier chain of the recess of recessed driven rotary body that the external diameter of driven rotary body becomes, or littler than the diameter of pitch circle, therefore wholely realizes miniaturization.
Because the recess of the recessed driven rotary body of the pin of carrier chain, therefore, and to compare as the situation of driven rotary body with the roller shape rotary body that does not possess recess at peripheral part, the entering quantitative change that driven rotary body gets into carrier chain is big.Like this, get into the entering quantitative change of carrier chain when big at driven rotary body, because the support region of driven rotary body supporting carrier chain increases, so carrier chain is difficult to tilt with respect to driven rotary body.
In addition; Though the pin of carrier chain at most only is recessed into about half to the recess of driven rotary body; But, with on pin outside the situation of the large diameter roller of embedding etc. compare, carrier chain is difficult for moderately coming off from driven rotary body; Situation cause producing at carrier chain excessive loads because of paddy stalk obstruction etc. is inferior, and carrier chain moderately comes off from driven rotary body easily.
Thus, the whole realization of driven rotary body miniaturization, it is easy that the configuration in stalks conveying apparatus becomes.And,, therefore, can stably carry out the conveying of paddy stalk because carrier chain is difficult to tilt with respect to driven rotary body.In addition, guarantee transmission reliably thereby not only can make carrier chain be difficult to moderately come off, and under abnormal conditions such as paddy stalk obstruction, carrier chain is moderately come off, thereby can avoid stalks conveying apparatus to produce fault.
Second feature structure of the driven rotary body that the stalks conveying apparatus of the utility model is used is that the curvature of the bottom of the upstream side part of the driven rotary body direction of rotation of said recess and the said recess of ratio of curvature of downstream part is big.
Because the curvature of the ratio of curvature concave bottom of the upstream side of the driven rotary body direction of rotation of recess part and downstream part is big; Therefore; Bearing the pin of carrier chain of the rotation of drive sprocket takes in to recess from this downstream part of recess swimmingly; Subsequently, this upstream side part from recess breaks away from outside the recess swimmingly.In addition; If the curvature of the ratio of curvature concave bottom of this upstream side part of recess and this downstream part is big; The pin that then is accommodated in the carrier chain in the recess of driven rotary body does not contact with this downstream part with this upstream side part of recess, even perhaps contact, contact area is also little; Therefore, pin diminishes with the contact area of recess.
Because the pin of carrier chain is taken in smoothly repeatedly, broken away from respect to the recess of driven rotary body, therefore can stably carry the paddy stalk.In addition, because the pin of carrier chain diminishes with the contact area of recess, therefore, be suppressed the durability raising by the wear damage of the caused driven rotary body of pin.
The 3rd feature structure of the driven rotary body that the stalks conveying apparatus of the utility model is used is; Said driven rotary body rotation is bearing on the bolster that is fixed in support unit freely, and loads and unloads freely with said support unit and to be fixed on the scaffold.
The 4th feature structure of the driven rotary body that the stalks conveying apparatus of the utility model is used is; Said driven rotary body rotation is bearing on the bolster that is fixed in support unit freely; And load and unload with said support unit and to be fixed on freely on the scaffold; At the leading section of said support unit, being formed with when oblique below tilts and overlooks is leg-of-mutton anti-shedding part.
