Description

Technical Field

[0001] The present application relates to the technical field of driven rake accessories, and in particular to a rake blade structure of a driven rake. Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] A driven harrow refers to a device that uses the power transmitted by a tractor to cultivate the land and prepare the seed bed. The harrow blade is inserted into the field, and the power mechanism drives the harrow blade to rotate, breaking up the soil clods in the field, thus completing the process of cultivating the land.

[0004] Patent Publication (Announcement) No.: CN217406961 U discloses a rake blade structure mechanism of a driven rake and a driven rake. First, the rake blade is inserted into the rake blade installation groove, and the rake blade can only be inserted or disengaged from its slot through the rake blade installation groove, and then the splicing shaft is movably inserted into the rake blade fixing seat and the rake blade to limit the rake blade from being disengaged from the rake blade installation groove. Finally, the splicing shaft is kept inserted into the rake blade fixing seat and the rake blade through a locking assembly, and the assembly of the rake blade can be completed. However, the splicing shaft and the locking assembly are both inserted from below the rake teeth, that is, the end of the rake teeth close to the ground. In actual work, the soil easily covers the leaked part of the splicing shaft, which makes it inconvenient to disassemble the rake blade in actual work. After damage occurs, the soil needs to be cleaned before disassembly and assembly. Therefore, a driven rake blade that is easy to disassemble and assemble is needed. Utility Model Content

[0005] In order to solve the above problems, the present application proposes a rake blade structure for driving a rake.

[0006] The purpose of the present application is to provide a rake blade structure for driving a rake, wherein the rake blade is fixed to the connecting plate by passing a connecting rod on the rake blade through a connecting plate and tightening a nut on the connecting rod.

[0022] The present application is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] A rake blade structure for driving a rake, such as Figure 1-3 As shown, it includes: a connecting plate 1 and a rake blade 2, one end of the connecting plate 1 is fixedly connected to the rotating shaft 5 of the driving rake 7, the connecting plate 1 is rectangular, the rotating shaft 5 is located at the center of the connecting plate 1, and a rake blade 2 is installed on each of the four sides of the connecting plate 1. The rotating shaft 5 of the driving rake 7 drives the connecting plate 1 to rotate, and the rake blade 2 on the connecting plate 1 rotates under the drive of the connecting plate 1, and the rake blade 2 performs tillage during the rotation process.

[0025] like Figure 1 As shown, the four sides of the rotating shaft 5 are respectively provided with mounting holes, the rake blade 2 is rectangular, and one end of the rake blade 2 is provided with a sharp protrusion to facilitate tilling the field. Figure 2 As shown, a connecting rod 3 is provided at one end of the rake blade 2 away from the sharp protrusion, and an external thread 6 is provided on the connecting rod 3. The connecting rod 3 passes through the mounting hole of the connecting plate 1 and is fixed by a nut 4. The nut 4 is at the end of the connecting plate 1 away from the rake blade 2. During the rotation and tillage process of the rake blade 2, due to the obstruction of the connecting plate 1, the soil will not reach the nut 4 on the connecting plate 1. In this way, when disassembling the rake blade 2, the nut 4 can be directly unscrewed, the rake teeth can be pulled out of the mounting hole, and new rake teeth can be replaced. This straight-up and straight-down installation method is simple and convenient.

[0026] like Figure 1 As shown, one connecting plate 1 corresponds to four rake blades 2, and the four rake blades 2 are respectively installed on the four sides of the connecting plate 1, and each rake blade 2 is parallel to the adjacent sides, thus forming a rake blade 2 structure.

[0027] A gasket is further provided between the nut 4 and the connecting plate 1, and it is more convenient to fix the nut 4 through the gasket.

[0028] like Figure 2 As shown, two connecting rods 3 are provided on the rake blade 2, and the two connecting rods 3 are axially symmetrical with the center line of the rake blade 2, which is convenient for installation.

[0029] The connecting plate 1 is square, and two mounting holes are arranged on each side of the square connecting plate 1 .

[0030] like Figure 1 As shown, the rake blade 2 and the connecting plate 1 are perpendicular to each other, the rotating shaft 5 and the connecting plate 1 are perpendicular to each other, and the rake blade 2 and the rotating shaft 5 are parallel to each other.

[0031] The length of the rake blade 2 is greater than the maximum side length of the connecting plate 1 , so that the connecting plate 1 can be kept farther from the ground during tillage by the isolation of the longer rake blade 2 , and no soil will splash onto the connecting plate 1 .

[0032] In the technical solution of the present application, the rake blades 2 are fixed by the connecting plate 1, and four rake blades 2 are fixed on the four sides of the connecting plate 1, and each rake blade 2 is parallel to the adjacent sides, thus forming a group of rake blades 2 structure for driving the rake 7, such as Figure 3 As shown, each driving rake 7 has multiple groups of rake blades 2 structures, which are connected to the center of the connecting plate 1 through the rotating shaft 5. When the rotating shaft 5 drives the connecting plate 1 to rotate, the rake blades 2 on the connecting plate 1 rotate as the connecting plate 1 rotates, so that the soil in the field can be broken up to achieve tillage. In this process, the connecting rod 3 of the rake blade 2 passes through the connecting plate 1 and is fixed by the nut 4. The nut 2 is located on the side of the connecting plate 1 away from the land and is not easy to be attached to the soil. This straight up and down installation method is simple and fast. The connecting plate 1 can also block the soil splashed by the rake blade 2 during the tillage process to prevent the soil from covering the nut 4 and making it inconvenient to disassemble. After the rake blade 2 is damaged, it can also be disassembled through the nut 4. The installation is quick and there is no need to clean the nut 4, which improves the efficiency of disassembling and replacing new rake blades 2.

[0033] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or variations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
