Description

Technical Field

[0001] The present application relates to the technical field of drive rake accessories, and in particular to a protective device for a drive 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 is a device that utilizes the power of a tractor to cultivate the land and prepare the seed bed. It is able to achieve deep soil crushing, breaking the bottom layer of the plow without destroying the soil structure, crushing the soil evenly and with good results.

[0004] Authorization announcement number: CN217633502U, discloses a protective device for the oil seal of the bearing seat of a driving rake. By designing the rake tooth seat as a double-ring structure and installing it into the bearing seat, it can solve the problem that entanglements such as wires and electric wires in the farmland are difficult to enter the bearing seat, thereby effectively protecting the oil seal. In actual work, the connection between the rotating shaft and the rake teeth will leak out of the bearing seat, and it is difficult to protect it with the existing technology. If hard debris such as stones are encountered, when the rake teeth rotate, some of the stones hit by the rake teeth will hit the connection between the rotating shaft and the rake teeth, causing the rake teeth to fall off or be damaged. Therefore, a protective device is needed to protect the connection between the rotating shaft and the rake teeth. Utility Model Content

The connecting seat is tightly attached to the crossbeam of the driving rake, and the bolts are passed through the mounting holes. In this way, the protective shell can be fixedly installed on the crossbeam, which makes the installation simpler and more convenient. It prevents adjacent rake teeth from hitting stones onto the connection between the adjacent rake teeth and the rotating shaft, thereby protecting the connection between the rotating shaft and the rake teeth.

[0017] 2. The baffle plate on the side of the crossbeam of the present invention blocks the flying stones on the side, prevents the adjacent driving rake from causing stones to splash onto the driving rake next door during the working process, and protects the rake teeth of the driving rake.

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

[0023] Example 1

[0024] A protective device for driving a rake, such as Figure 1-3As shown, it includes: a protective shell 3, which is a cone that is wide at the top and narrow at the bottom. The wider end of the protective shell 3 is fixedly connected to the crossbeam 1 of the driving rake, and the diameter of the narrower end of the protective shell 3 is greater than the maximum width of the rake teeth 2. The rake teeth 2 cross the center of the protective shell 3, so that the protective shell 3 can protect the connection between the rake teeth 2 and the rotating shaft 9 to prevent impact by harder stones.

[0025] like Figure 3 As shown, a connecting seat 5 is provided at one end of the protective shell 3 close to the driving rake cross beam 1. The connecting seat 5 is annular, and the inner ring of the annular ring is fixedly connected to the wider end of the protective shell 3. A mounting hole 8 is provided on the connecting seat 5, and the protective shell 3 is fixed to the cross beam 1 of the driving rake by passing bolts through the mounting hole 8.

[0026] like Figure 2 As shown, the distance from the narrower end of the protective shell 3 to the driving rake cross beam 1 is greater than one third of the length of the rake teeth 2, which can better protect the connection between the rotating shaft 9 and the rake teeth 2.

[0027] like Figure 1 As shown, the diameter of the wider end of the protective shell 3 is smaller than the width of the beam 1, which is convenient for installation.

[0028] The angle between the protective shell 3 and the connecting seat 5 is 135 degrees.

[0029] like Figure 1 As shown, it also includes baffles 4, which are located at both ends of the driving rake beam 1. The baffles 4 are fixedly connected to the driving rake beam 1 through a connecting rod 7, so that the baffles 4 prevent stones on the side of the driving rake from splashing to the position where the rotating shaft 9 is connected to the rake teeth 2.

[0030] like Figure 1 As shown, the width of the baffle 4 is greater than the width of the beam 1, and the protection range is wider.

[0031] In the technical solution of the present application, by covering the protective shell 3 at the connection between the rotating shaft 9 and the rake teeth 2, the connection between the rotating shaft 9 and the rake teeth 2 can be protected. The rake teeth 2 are directly passed through the center of the protective shell 3 through the conical protective shell 3 that is wide at the top and narrow at the bottom. The connecting seat 5 is in close contact with the crossbeam 1 of the driving rake, and the bolts are passed through the mounting holes 8. In this way, the protective shell 3 can be fixedly installed on the crossbeam 1, and the installation is simpler and more convenient. The adjacent rake teeth 2 are prevented from hitting stones to the connection between the adjacent rake teeth 2 and the rotating shaft 9, and the connection between the rotating shaft 9 and the rake teeth 2 is protected. The bearing seat 6 located outside the crossbeam 1 can also be protected. The baffle 4 installed on the side of the crossbeam 1 can be used to prevent the adjacent driving rake from causing stones to splash onto the driving rake next door during operation, thereby protecting the rake teeth 2 of the driving rake.

[0032] 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.
