Description

Technical Field

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

[0002] Usually, when a community or park needs to plant lawns or vegetation, a small plowing machine is needed to turn the soil so that the soil is more fertile and the lawn or vegetation grows more luxuriantly. The plowing machine includes a machine body and a blade detachably mounted on the machine body. When plowing, the blade needs to enter the soil to turn the soil, and the machine body drives the blade to rotate and move.

[0003] The blade of the plowing machine includes a base plate and a plurality of soil turning blades mounted on the base plate. In the related art, in order to reduce maintenance costs, the soil turning blades are generally fixed to the base plate by bolts. Therefore, if one of the soil turning blades hits a stone and curls during plowing, it is only necessary to remove the corresponding soil turning blade for replacement. However, the soil turning blade is only fixed to the base plate by bolts, so that the contact area between the soil turning blade and the base plate is small, which makes the soil turning blade easy to shake during use after installation, resulting in poor stability. Utility Model Content

[0004] In order to improve the stability of a plowing machine blade during use, the present application provides a plowing machine blade.

[0005] The present application provides a plowing machine blade, which adopts the following technical solution:

[0006] A plow blade comprises a base plate, a tiller blade and a cover plate, wherein a mounting groove is provided on a side of the cover plate close to the base plate, one side of the tiller blade is inserted into the mounting groove, and the other side protrudes from the mounting groove, and a clamping bolt is provided on the cover plate for fixing the base plate, the tiller blade and the cover plate.

[0007] In order to enable the tilling blade to be preliminarily pre-positioned on the base plate, a limiting frame for inserting and limiting one side of the tilling blade is provided on one side of the base plate close to the cover plate.

[0008] In order to facilitate the limit frame to smoothly enter the installation groove when the cover plate and the base plate are buckled together, the limit frame is inserted into the installation groove, and a guiding inclined surface is provided on the limit frame for easy insertion into the installation groove.

[0009] In order to preliminarily limit the position of the tilling blade before the clamping bolt is installed, a positioning column is provided at the bottom of the installation groove, and a positioning groove for the limiting column to be inserted is opened on the tilling blade.

[0010] In order to enable the positioning post to be smoothly inserted into the positioning groove, the positioning post is provided with an arc surface which facilitates the positioning post to be inserted into the positioning groove.

[0011] In order to enable the clamping bolt to fix the base plate, the tilling blade and the cover plate, a hole for the clamping bolt to pass through is opened on the tilling blade, and a bolt hole connected to the passing hole for the clamping bolt to pass through is opened on the base plate, the side of the clamping bolt facing away from the cover plate protrudes from the bolt hole, and an anti-slip nut is installed on the side of the clamping bolt facing away from the cover plate.

[0012] In order to allow the clamping bolt to pass normally within the error range of the base plate or the soil-turning blade, the diameter of the bolt hole is larger than the diameter of the penetration hole.

[0013] In order to improve the soil turning effect, the side of the soil turning blade away from the base plate is bent toward the side away from the cover plate.

[0014] The soil turning blade is an arc-shaped blade.

[0015] In order to improve the efficiency of soil turning, a plurality of soil turning blades are provided, and the plurality of soil turning blades are circumferentially spaced apart on the base plate.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] The part where the tiller blade is connected to the base plate is wrapped by the base plate cover, so that the contact area between the fixed part and the base plate and the cover plate becomes larger, and then it is fixed together with the base plate and the cover plate by the clamping bolts, so that the stability during use after installation is stronger;

[0018] When the soil turning blade is assembled, it can be initially limited on the base plate through the limiting frame, and the penetration hole and the bolt hole can be more accurately connected, so as to facilitate the subsequent penetration and fixing of the tightening bolt;

[0019] Insert one side of the soil-turning blade into the mounting groove, and insert the positioning column into the positioning groove at the same time, so that the soil-turning blade can be limited in the mounting groove. Even if one of the clamping bolts is loose, the soil-turning blade is not easy to separate from the mounting groove, and the soil-turning blade can still work normally for soil turning with the cooperation of the limiting frame, the positioning column and the positioning groove.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses a plow blade. Figure 1 The plowing machine blade includes a base plate 1, a tilling blade 2 and a cover plate 3. The tilling blade 2 is located between the base plate 1 and the cover plate 3, and the base plate 1 and the cover plate 3 form a clamping state for the tilling blade 2. The cover plate 3 is provided with a clamping bolt 4 that fixes the base plate 1, the tilling blade 2 and the cover plate 3 together. The tilling blade 2 can have a larger contact area with the base plate 1 and the cover plate 3 through the clamping of the base plate 1 and the cover plate 3, so that the tilling blade 2 is more stable after installation, and thus the plowing machine blade is more stable during use.

[0027] In this embodiment, the tilling blade 2 is preferably an arc-shaped blade, and the tilling blade 2 is bent along the side of its own extension direction away from the base plate 1 in the direction away from the cover plate 3, so that the tilling blade 2 can better enter the soil and turn the soil below to the top. Among them, there are multiple tilling blades 2, and the multiple tilling blades 2 are arranged circumferentially on the base plate 1. In this embodiment, four tilling blades 2 are preferably provided, and the four tilling blades 2 have the same structure. The following is explained by taking one tilling blade 2 as an example.

[0028] Reference Figure 1 and Figure 2 The tilling blade 2 includes a handle portion 21 and a blade portion 22. The handle portion 21 is located at one end of the blade portion 22, and the handle portion 21 and the blade portion 22 are integrally formed. The handle portion 21 is provided with a through hole 23 that penetrates through the handle portion 21. The clamping bolt 4 is passed through the through hole 23 to fix the tilling blade 2, the base plate 1 and the cover plate 3. The blade portion 22 is used to enter the soil for tilling. The bend is located at the blade portion 22. Such a design enables the handle portion 21 to better fit and fix with the base plate 1.

[0029] The substrate 1 is integrally formed with a limiting frame 11 on one side close to the cover plate 3. The limiting frame 11 is a U-shaped frame. The side of the handle 21 away from the blade 22 is inserted into the limiting frame 11, and the blade 22 protrudes from the limiting frame 11 and the substrate 1 is exposed outside the substrate 1. The inner peripheral wall of the limiting frame 11 abuts against the outer peripheral wall of the handle 21, thereby preliminarily limiting the soil turning blade 2. Since there are four soil turning blades 2, there are also four limiting frames 11, and the four limiting frames 11 correspond to the four soil turning blades 2 one by one.

[0030] Reference Figure 2 and Figure 3 , the through hole 23 is located inside the limiting frame 11, and a bolt hole 12 is also provided on one side of the substrate 1 where the limiting frame 11 is provided, and the bolt hole 12 is communicated with the through hole 23, and the threaded end of the clamping bolt 4 will pass through the bolt hole 12 after passing through the through hole 23. The diameter of the bolt hole 12 is slightly larger than the through hole 23, so that there is a certain adjustment margin after the clamping bolt 4 is inserted into the bolt hole 12, and the clamping bolt 4 can pass through the bolt hole 12 smoothly after ensuring that the handle 21 is accurately located in the limiting frame 11.

[0031] Combination Figure 2 Reference Figure 3 and Figure 4 The cover plate 3 is provided with a mounting groove 31 on one side close to the base plate 1, and the limiting frame 11 and the portion of the handle 21 located in the limiting frame 11 can be inserted into the mounting groove 31. Since the blade 22 needs to protrude from the base plate 1, the side of the mounting groove 31 close to the side of the cover plate 3 is open. Since four tilling blades 2 are provided, four mounting grooves 31 are also provided, and the four mounting grooves 31 correspond to the four tilling blades 2 one by one.

[0032] In order to facilitate the smooth insertion of the limiting frame 11 into the installation groove 31 , the outer edge of the limiting frame 11 close to the cover plate 3 is configured as a guiding slope 13 .

[0033] The bottom of the installation groove 31 is integrally formed with a positioning column 32, and a positioning groove 24 for inserting the positioning column 32 is provided on the side of the handle portion 21 close to the cover plate 3. After the cover plate 3 is engaged with the base plate 1, the positioning column 32 will be inserted into the positioning groove 24, and the tiller blade 2 will be limited and will not be easily separated from the installation groove 31. Among them, the outer edge of the positioning column 32 close to the positioning groove 24 is provided with an arc surface 33, and the outer diameter of the end of the positioning column 32 close to the positioning groove 24 is smaller than the groove diameter of the positioning groove 24 under the action of the arc surface 33, so that the positioning column 32 can be inserted into the positioning groove 24 more smoothly.

[0034] Reference Figure 2 and Figure 4The cover plate 3 is provided with a through hole 34 on the side away from the base plate 1, and the threaded end of the clamping bolt 4 will pass through the through hole 34, the through hole 23 and the bolt hole 12 in sequence and be exposed outside the base plate 1. The end of the clamping bolt 4 away from the cover plate 3 is threadedly installed with an anti-slip nut 41, and the driving end of the clamping bolt 4 will cooperate with the anti-slip nut 41 to clamp and fix the base plate 1, the handle 21 and the cover plate 3.

[0035] The implementation principle of a plowing machine blade in an embodiment of the present application is as follows: the handle portion 21 of the soil-turning blade 2 is inserted into the limiting frame 11 and then into the mounting groove 31, so that the base plate 1 and the cover plate 3 form a wrapping state for the handle portion 21, so that the contact area between the fixed portion and the base plate 1 and the cover plate 3 becomes larger, and then it can be more stable after being fixed by the tightening bolt 4.

[0036] In addition, after the handle portion 21 is inserted into the mounting groove 31, the positioning column 32 will also be inserted into the positioning groove 24, thereby limiting the soil-turning blade 2 in the mounting groove 31. Even if one of the clamping bolts 4 is loosened, the soil-turning blade 2 is not easy to disengage from the mounting groove 31, and the soil-turning blade 2 can still perform normal soil-turning work with the cooperation of the limiting frame 11, the positioning column 32 and the positioning groove 24.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
