Description

Technical Field

[0001] The utility model relates to the technical field of ridging machine accessories, in particular to a ridging knife group. Background Art

[0002] The ridging knife set is an accessory on the ridging machine used to loosen the soil. There are two commonly used ridging knives. One is a plurality of blades fixedly installed on the main shaft at intervals. The rotation of the main shaft of the ridging machine transmission box drives the plurality of blades to rotate and plow the soil. The other is a spiral integrated blade. The blade is fixedly installed on the main shaft. The rotation of the main shaft drives the blade to rotate to plow the soil. At the same time, the rotation of the spiral blade can also separate the plowed soil, so it is widely used.

[0003] Since the blades have large radial and axial forces at the same time when plowing, the ridging blades bear a large load. In order to meet the soil collection volume of ridging, the ridging machine needs to provide a large power for the ridging blades to turn the soil and move, which increases the energy consumption of the ridging machine. Utility Model Content

[0004] In order to reduce the energy consumption of a ridging machine, the utility model provides a ridging knife group.

[0005] The present application provides a ridging knife group, which adopts the following technical solution:

[0006] A ridging knife group comprises a mounting shaft, a ridging blade arranged on the mounting shaft and a plurality of ridging blades arranged on the mounting shaft, wherein the mounting shaft is used to be connected to a transmission box main shaft, the ridging blade is arranged at one end of the mounting shaft close to the transmission box main shaft, the ridging blade is located on a side of the ridging blade away from the transmission box main shaft, a plurality of the ridging blades are arranged on the mounting shaft at intervals and extend spirally along the length direction of the mounting shaft, and a blade width of each of the ridging blades is greater than a blade width of the ridging knife.

[0007] By adopting the above technical scheme, the main shaft of the transmission box drives the installation shaft to rotate, and the installation shaft drives the soiling blade and the ridging blade to rotate. The soiling blade crushes and excavates the soil close to the main shaft of the transmission box, and the ridging blade plows the soil on the side of the soiling blade away from the main shaft of the transmission box. The soil on the outside is transported inward by the action of the ridging blade, and the crushed and plowed soil is thrown back to form ridges under the action of the spirally extended ridging blade. The soil is crushed, excavated, plowed and transported through the cooperation of the soiling blade and the ridging blade, reducing the probability of soil blocking the transmission box and increasing the resistance of the ridging machine. At the same time, the spirally extended ridging blade generates a forward thrust for the machine, thereby improving the convenience of the ridging machine to travel, thereby achieving the goal of reducing the machine load while meeting the ridging soil collection amount, reducing the risk of sudden forward rush and injury to people due to the large power of the ridging machine when working, thereby reducing the energy consumption of the ridging machine.

[0008] Optionally, two ridging blades are provided, and the two ridging blades are arranged opposite to each other on the mounting shaft, and the blade width of the ridging blade gradually increases from one end close to the mounting shaft to the other end.

[0009] By adopting the above technical solution, the rotation of the mounting shaft drives the two ridging blades to rotate, and the soil crushing force is increased by increasing the width and number of the ridging blades, thereby reducing the energy consumption of the ridging machine.

[0010] Optionally, four ridging blades are provided, and the four ridging blades are arranged on the mounting shaft in sequence from the inside to the outside, and a spiral angle is formed between the ridging blade and the axis of the mounting shaft.

[0011] Optionally, the spiral angle is 20 degrees.

[0012] By adopting the above technical scheme, the installation shaft rotates to drive the four ridging blades to rotate. The spiral angle, that is, the angle of entry of the ridging blades into the soil, is reduced to 20 degrees. The soil on the outside is transported inwards and thrown back to form ridges under the action of the ridging blades, so as to achieve soil tillage and ridging. While meeting the ridging soil collection volume, the machine load is reduced, and the risk of sudden forward rush and injury to people due to the large power of the ridging machine when working is reduced, thereby reducing the energy consumption of the ridging machine.

[0013] Optionally, the outer edge of the ridging blade has a reinforcement portion, and the wear resistance coefficient of the reinforcement portion is greater than the wear resistance coefficient of the blade surface of the ridging blade.

[0014] By adopting the above technical solution, the edge of the ridging blade preferentially contacts the soil and plows the soil, thereby improving the wear resistance of the reinforced portion, thereby increasing the tillage effect of the soil and extending the service life of the ridging blade.

[0015] Optionally, the mounting shaft is provided with a mounting seat corresponding to the ridging blade one by one, the mounting seat has a mounting opening for inserting the ridging blade, the mounting seat is provided with a locking screw for locking the ridging blade, and the locking screw is threadedly connected with a locking nut.

[0016] By adopting the above technical solution, during installation, the mounting end of the ridging blade is inserted into the mounting opening, the locking screw is passed through the mounting seat and the ridging blade, the locking nut is rotated for positioning, and the reverse operation can be performed to disassemble, thereby improving the convenience of installation, positioning, disassembly and replacement of the ridging blade.

[0017] Optionally, a connecting seat corresponding to the ridging blade one by one is provided on the mounting shaft, and a plurality of the connecting seats are spirally arranged on the mounting shaft at intervals, the spiral angle of the connecting seat is consistent with the spiral angle, and the end of the ridging blade close to the mounting shaft is fitted with the connecting seat, and a connecting bolt is provided on the connecting seat, and the connecting bolt passes through the connecting seat and the ridging blade in turn, and a connecting nut for positioning the ridging blade is threadedly connected to the connecting bolt.

[0018] By adopting the above technical solution, the spiral angle of the connecting seat is consistent with the spiral angle. During installation, it is only necessary to make the ridging blade fit the connecting seat, pass the connecting bolt through the connecting seat and the ridging blade, and rotate the connecting nut to position the ridging blade. It can be disassembled by reverse operation, thereby improving the convenience of installation, positioning, disassembly and replacement of the ridging blade.

[0019] Optionally, two installation shafts are provided, and the two installation shafts are on the same horizontal line and are respectively located on both sides of the main shaft of the transmission box.

[0020] By adopting the above technical scheme, the main shaft of the transmission box drives the two installation shafts to rotate, and the installation shafts drive the corresponding soil-raising blades and ridging blades to rotate. The soil-raising blades crush and excavate the soil located at the main shaft of the transmission box, and the ridging blades plow the soil on the side of the soil-raising blades away from the main shaft of the transmission box. The soil on the outside is transported inward by the action of the ridging blades, and the crushed and plowed soil is thrown backward along the center line of the main shaft of the transmission box to form ridges under the action of the spirally extended ridging blades, thereby reducing the probability of soil blocking the transmission box and increasing the resistance of the ridging machine. At the same time, the spirally extended ridging blades generate a forward thrust for the machine, thereby improving the convenience of the ridging machine's movement, thereby reducing the energy consumption of the ridging machine.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The ridging blade crushes and digs the soil close to the main shaft of the transmission box, and the ridging blade plows the soil on the side of the ridging blade away from the main shaft of the transmission box. The soil on the outside is transported inward by the ridging blade, and the crushed and plowed soil is thrown backward to form ridges under the action of the spirally extended ridging blade. The soil is crushed, excavated, plowed and transported by the cooperation of the ridging blade and the ridging blade, reducing the probability of soil blocking the transmission box and increasing the resistance of the ridger. At the same time, the spirally extended ridging blade generates a forward thrust for the machine, which improves the convenience of the ridger to travel, thereby achieving the goal of reducing the machine load while meeting the ridging soil collection amount, reducing the risk of sudden forward rush and injury to people due to the large power of the ridger when working, thereby reducing the energy consumption of the ridger.

[0023] 2. The rotation of the mounting shaft drives the four ridging blades to rotate. The spiral angle is the angle of entry of the ridging blades into the soil. The angle of entry of the ridging blades into the soil is reduced to 20 degrees. The soil on the outside is transported inwards and thrown back to form ridges under the action of the ridging blades, so as to achieve soil tillage and ridging. While meeting the ridging soil collection volume, the machine load is reduced, and the risk of sudden forward rush and injury to people due to the large power of the ridging machine when working is reduced, thereby reducing the energy consumption of the ridging machine.
