Description
Technical field
The utility model relates to a kind of structure of novel threshing toothed bar, and particularly a kind of structure of the threshing toothed bar be arranged on harvester threshing drum, belongs to technical field of agricultural machinery.
Background technology
Crops are remaining stalk in the ground after harvesting, normally stalk is incinerated, and then when ploughing, is blended in by stalk in soil, as fertilizer.But in the season of harvesting, a lot of peasant household's crop straw burnings, full of smoke, shroud the earth, severe contamination is caused to air.
For solving the problem of crop straw burning, some grain headers adopt the method for crushed stalk, namely at the external stalk crasher of threshing cylinder.Threshing cylinder is provided with many threshing toothed bars, when sheller unit works, cereal and stalk put under in threshing cylinder by the threshing tooth on threshing toothed bar, and cereal falls into vibratory sieve in the stirring of threshing cylinder, and stalk enters in stalk crasher and pulverizes under the stirring of threshing cylinder.But existing stalk crasher is due to the restriction by position and space, volume can not be very large, and the diameter of cracker inner rotatable portion is also relatively little, and the crushing effect of stalk is not just also fine.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of novel threshing toothed bar that can improve crushed stalk effect, improve threshing performance, can alleviate threshing cylinder load simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel threshing toothed bar, comprises ratch and is arranged on the threshing tooth on ratch, it is characterized in that,
The head of described ratch, afterbody are equipped with threshing blade, the quantity of the threshing blade that ratch head is arranged is less than the quantity of the aft mounted threshing blade of ratch, described threshing tooth is arranged between the threshing blade of ratch head and afterbody, and threshing tooth, threshing blade are arranged on ratch equably;
Described threshing tooth is V-shaped, is made up of threshing tooth top and threshing tooth root, and the two ends of threshing tooth root are connected with the one end at ratch and threshing tooth top respectively, and the angle of threshing tooth top and threshing tooth root is obtuse angle.
The threshing blade that described ratch head is arranged is 1-3 root, and the aft mounted threshing blade of ratch is 2-5 root.
The obtuse angle angle of described threshing tooth top, threshing tooth root is 100 °-170 °.
The two sides of described threshing tooth are equipped with friction line.
Described threshing blade is connected with ratch by blade mount pad.
Described threshing tooth and ratch are for being threaded or being welded to connect.
In the utility model, the head of ratch, afterbody are connected with the head of threshing cylinder, afterbody respectively, and ratch head is provided with 1-3 root threshing blade, and ratch afterbody is provided with 2-5 root threshing blade.And threshing tooth is V-shaped, connect into obtuse angle (namely threshing tooth top bends in one end of threshing tooth root, and the direction of threshing tooth top bending is contrary with the direction of motion of threshing cylinder) by threshing tooth top and threshing tooth root.During sheller unit work, cereal and stalk are drawn in threshing cylinder by threshing tooth, threshing blade, and under the stirring of threshing cylinder, cereal enters in vibratory sieve, and stalk enters in cracker from threshing cylinder afterbody and pulverizes.Because stalk is long, the threshing blade being arranged on ratch head first by long straw cutting, and then can carry out threshing, this reduces the load of threshing cylinder.The bending of threshing tooth top is in one end of threshing tooth root, and obtuse angle structure can allow chaotic stalk (as grass group, disorderly grass) slip over threshing tooth top more easily, reduces resistance, further mitigates the load of threshing cylinder.The friction line of threshing tooth two sides adds frictional force during threshing, is convenient to threshing, improves threshing performance.Because ratch afterbody is provided with threshing blade, therefore stalk is through threshing cylinder afterbody, threshing blade can carry out cutting and grinding again to stalk, stalk after carrying out cutting and grinding is sent in stalk crasher and again pulverizes by threshing cylinder, the setting of threshing blade alleviates the live load of stalk crasher, improves the crushing effect of stalk crasher.
Long-term and the stalk of threshing tooth, threshing blade, cereal percussion, belong to consumable accessory, in the utility model, threshing tooth and ratch are screw thread or are welded to connect, after threshing tooth wearing and tearing, without the need to threshing toothed bar entirety being disassembled from threshing cylinder, only threshing tooth need be changed, without the need to changing ratch, saving material so on the one hand, having improve operating efficiency on the other hand.Threshing blade is connected with ratch by blade mount pad, makes to connect more firm, only needs periodic replacement threshing blade simultaneously.
The utility model is simple and reasonable, and manufacture easily, cost is low, and result of use is good, long service life, improves the crushing effect of cracker, improves threshing performance, can alleviate threshing cylinder load simultaneously, improve operating efficiency, have the wide market space.
