Abstract

The utility model discloses a spiral rotary blade assembly which comprises a transmission shaft, a plurality of knife rests and a plurality of rotary blades, wherein the knife rests are evenly arranged in the axial direction of the transmission shaft, and the rotary blades are arranged on the knife rests. The knife rests are in a strip shape, the middle of each knife rest is fixedly connected with the transmission shaft, two ends of each knife rest are respectively connected with a rotary blade, and the axial direction of each knife rest is arranged along the circumference of the transmission shaft in a spiral and equal angular difference mode. The spiral rotary blade assembly has the advantages of being capable of effectively reducing impact force on the rotary blade assembly by a soil body, reducing shaking amplitude of agricultural machinery when plough is conducted, prolonging the service life of the device, lowering requirements for a power device when the rotary blade assembly ploughs and operates, and improving efficiency of the plough.

Description

Spirality is ploughed the cutter assembly

Technical field

The utility model relates to a kind of agricultural tillage equipment, relates in particular to a kind of spirality and ploughs the cutter assembly.

Background technology

Agricultural machinery is equipment commonly used in the agricultural production, the advantage that it possesses, and volume is little, cost is low, function is many; When agricultural machinery be used for is ploughed, only need cultivated cutter assembly with correspondence be installed on the agricultural machinery and get final product;

There is the big problem of vibration in existing agricultural machinery when ploughing, the main cause that causes vibration is owing to plough the cutter assembly when ploughing, and ploughs cutter and suddenlys change when contact with the soil body from vacant state, and the impulsive force that the reaction force of the soil body causes cultivated cutter causes; Cultivated cutter on the existing cultivated cutter assembly is proper alignment, during the arable land, many handles are ploughed cutter and are contacted with the soil body simultaneously, the soil body is bigger to the impulsive force of ploughing the cutter assembly, and agricultural machinery is significantly shaken when causing the arable land, and this shake not only causes the controlled variation of agricultural machinery, also can cause certain influence to the life-span of equipment, and many handles are ploughed cutter and are inserted simultaneously in the soil body, and suffered resistance is also very big, and is also higher relatively to the requirement of power set.

The utility model content

At the problem in the background technology, the utility model proposes a kind of spirality and plough the cutter assembly, comprise power transmission shaft, a plurality of knife rests along transmission shafts to even setting, and the many handles that are arranged on the knife rest are ploughed cutter, its improvement is: described knife rest is bar shaped, fixedly connected with power transmission shaft in the knife rest middle part, the knife rest two ends respectively connect a cultivated cutter; Each knife rest axially circumferentially press the setting of spiral form, equal angles difference along power transmission shaft.

Principle of the present utility model is: the knife rest by the spirality setting makes the spread pattern of ploughing cutter also by helical pattern, when power transmission shaft drives blade holder turns, many handles are ploughed cutter and are contacted with the soil body successively, synchronization, only having a cultivated cutter to sport with the soil body from vacant state contacts, can reduce the soil body greatly to ploughing the impact that the cutter assembly causes, reduce the jitter amplitude of agricultural machinery when ploughing, thereby improve handling, life-span of prolonging equipment of agricultural machinery, simultaneously, also can reduce the requirement to power set, reduce production costs.

Knife rest and cultivated cutter both can adopt monolithic construction also can adopt split-type structural, when adopting monolithic construction, can reduce the cost of manufacture of knife rest and cultivated cutter, when adopting split-type structural, can be convenient to plough replacing and maintenance after cutter weares and teares, at knife rest and the cultivated cutter of split-type structural, the utility model has also proposed following preferred connected mode: the knife rest end is provided with bolt hole, plough the cutter tail end and be provided with connecting hole, be bolted to connection between bolt hole and the connecting hole.

In order to improve knife rest and cultivated cutter connection stability, the utility model has also been done following improvement: the both sides that tool axis makes progress respectively are provided with a baffle plate, the knife rest at baffle position place forms the groove shape structure that cross section takes the shape of the letter U, and ploughs the cutter tail end and is nested in the groove shape structure.Baffle plate can carry out block to the circumferential play of ploughing the cutter tail end, improves knife rest and cultivated cutter connection stability.

At power transmission shaft, the utility model has also proposed following preferred version: described power transmission shaft is shaped as hexagonal prism shape, and the knife rest middle part is provided with corresponding hexagonal hole, and knife rest and power transmission shaft welding are fixing.

At the quantity of knife rest, the utility model has also proposed the following preferred plan of establishment: described knife rest quantity is 6,6 knife rests axially circumferentially by spiral form, every interval 30 degree a knife rest is set along power transmission shaft.

Useful technique effect of the present utility model is: can effectively reduce the soil body to ploughing the impulsive force that the cutter assembly causes, reduce the jitter amplitude of agricultural machinery when ploughing, prolong equipment life, to the requirement of power set, improve the efficient of ploughing when reducing the arable land operation.

Embodiment

A kind of spirality is ploughed the cutter assembly, the a plurality of knife rests 2 that comprise power transmission shaft 1, axially evenly arrange along power transmission shaft 1, and the many handles that are arranged on the knife rest 2 plough cutter 3, its improvement is: described knife rest 2 is bar shaped, fixedly connected with power transmission shaft 1 in knife rest 2 middle parts, knife rest 2 two ends respectively connect a cultivated cutter 3; Each knife rest 2 axially circumferentially press spiral form, the setting of equal angles difference along power transmission shaft 1.

Further, knife rest 2 ends are provided with bolt hole, plough cutter 3 tail ends and are provided with connecting hole, are bolted to connection between bolt hole and the connecting hole.

Further, knife rest 2 both sides on axially respectively are provided with a baffle plate 4, and the knife rest 2 of baffle plate 4 positions forms the groove shape structure that cross sections take the shape of the letter U, and ploughs cutter 3 tail ends and is nested in the groove shape structure.

Further, described power transmission shaft 1 is shaped as hexagonal prism shape, and knife rest 2 middle parts are provided with corresponding hexagonal hole, and knife rest 2 is fixing with power transmission shaft 1 welding.

Further, described knife rest 2 quantity are 6,6 knife rests 2 axially circumferentially by spiral form, every interval 30 degree a knife rest 2 is set along power transmission shaft 1.
