Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural machinery, and particularly relates to a high-frequency vibration cutting type anti-blocking straw cleaning device with support. BACKGROUND

[0002] At present, the anti-blocking devices of the no-tillage seeding machine mainly include the stubble breaking type and the straw separating type. The stubble breaking type mostly adopts the driving type disc cutter to cut the straw to ensure the good passability of the seeding machine. For example, the patent No. ZL200520144400.6, the invention patent "driving anti-blocking wheat no-tillage seeding machine", the cutter shaft installed on the wheat seeding machine rotates under the driving of the power to break the corn straw and weeds hanging on the shovel handle of the furrow opener to prevent the furrow opener from being blocked. The straw separating type separates the straw and weeds in front of the furrow opener to the two sides by the sweeping, pushing and flowing ways to form a clean seeding belt. For example, the patent No. ZL200810051083.1, the invention patent "a profiled claw type floating stubble and weed cleaning mechanism", a pair of "eight" type finger-shaped straw pushing wheels installed in front of the furrow opener of the seeding machine can effectively sweep the straw, stubble and soil clods on the operation belt to achieve the anti-blocking effect. However, in the above two types of anti-blocking devices, the stubble breaking type mainly adopts the driving disc cutter, which is easy to cause the entangled straw blockage due to the more transmission devices and the small ground clearance. Although the straw separating type has a simple structure, it is difficult to effectively prevent the blockage when the straw coverage is large, and the resistance is large. Therefore, a new type of anti-blocking device is needed to combine the above two different anti-blocking principles to obtain a more ideal anti-blocking effect when the seeding machine is used in the no-tillage operation.

[0029] The present application will be further described in detail below with reference to the embodiments.

[0030] As shown in Figures 1-11 , a specific embodiment of a high-frequency vibration cutting type anti-blocking straw cleaning device provided by the present application is as follows:

[0031] The high-frequency vibration cutting type anti-blocking straw cleaning device comprises a rack 1, the upper end of the rack being a mounting plate 2, the front part of the rack 1 being a mounting fork 3, the mounting fork 3 being provided with a mounting shaft 4, the mounting shaft 4 being arranged along the horizontal direction left and right, and a horn type notched disc knife 5 being rotatably mounted on the mounting shaft 4.

[0032] As shown in Figure 3 , a plurality of horn cutters 9 are uniformly distributed on the outer edge of the horn type notched disc knife 5, and the outer edge of the horn cutter 9 has a blade structure; as shown in Figure 4 and Figure 5As shown, the upper part of the mounting fork 3 is fixed with a motor base 10, the motor base 10 is installed with a motor 11, the main shaft of the motor 11 is provided with an eccentric wheel 12, the mounting shaft 4 is provided with a high-frequency vibration knife 13, the high-frequency vibration knife 13 can rotate around the mounting shaft 4, a connecting rod 14 is arranged between the upper end of the high-frequency vibration knife 13 and the eccentric wheel 12, the two ends of the connecting rod 14 are respectively hinged to the upper end of the high-frequency vibration knife 13 and the eccentric position of the eccentric wheel 12, the lower part of the high-frequency vibration knife 13 is a cutting knife 15, the cutting knife 15 is in close contact with the outer surface of the horn type notched disc knife 5, and the cutting knife 15 cooperates with the horn cutter 9 to realize cutting operation.

[0033] Two groups of grass wheel assemblies are mounted on the rear side of the frame 1, and the two groups of grass wheel assemblies are symmetrically arranged left and right.

[0034] Preferably, as shown in the drawings, Figure 3 The outer edge of the horn cutter 9 is connected by a curve AB, a curve BC and a curve CD in sequence, wherein the curve AB and the curve BC are part curves of Archimedes spirals, and the curve CD is a circular arc curve. The special structure of the horn cutter 9 forms a certain angle with the blade curve of the high-frequency vibration knife 13, increases the kneading effect of the two, and makes the sliding cutting effect better during cutting, so that the working effect of the machine tool is better.

[0035] In order to make the high-frequency vibration knife 13 more flexible, as shown in the drawings, Figure 6 A plurality of circular holes 16 are formed in the eccentric wheel 12, the central angles of any two adjacent circular holes 16 are the same, the distances between all the circular holes 16 and the center of the eccentric wheel 12 gradually increase, the gradually increasing distance is constant, all the circular holes 16 are arranged in a certain curve, and the connecting rod 14 can be installed in one of the circular holes 16.

[0036] As shown in the drawings, Figures 7-10 Each group of grass wheel assemblies includes a spring tooth rod 17 and a concave grass wheel 18. The spring tooth rod 17 is located at the rear of the mounting fork 3, and the upper end of the spring tooth rod 17 is fixed to the upper part of the mounting fork 3. The lower end of the spring tooth rod 17 is fixed with a connecting shaft 19, and the connecting shaft 19 is inclined. Specifically, the inclination of the connecting shaft 19 is as follows: taking the direction perpendicular to the forward direction of the machine tool as the X axis, and taking the direction perpendicular to the plane where the spring tooth rod 17 is located as the Y axis, the angle between the connecting shaft 19 and the X axis is β, and the angle between the connecting shaft 19 and the Y axis is α.
