Example 1

Referring to fig. 1 to 10, an embodiment of a farming rake frame according to the present invention is shown, and the specific structure is as follows.

As shown in fig. 1, the present embodiment provides an agricultural harrow rack, which comprises a combined harrow plate 1, an elastic structure and a harrow rack body 3, wherein the combined harrow plate 1 is connected with the elastic structure. The elastic structure is connected with the harrow frame main body 3 in a welding mode. The farming harrow rack is formed by installing the combined harrow plate 1, the elastic structure and the harrow rack main body 3, and the elastic structure ensures that the combined harrow plate 1 has certain elasticity in the vertical direction.

In conventional harrow plates, the harrow chain is often connected to the harrow plate through steel columns or steel plates. If a certain plowing blade in the harrow chain rolls over a harder stone, the plowing blade can roll over the stone under the traction of the plowing and harrowing machine. At the moment, the harrow rack is lifted, and the contact area of other harrow pieces and the land is reduced or suspended. The weight of the harrow frame is almost completely applied to the harrow plate contacted with stones, so that the harrow plate is easy to break or bend, and the maintenance cost is increased. If a certain land has a lot of stones, the harrowing blade is difficult to harrow on the land in consideration of the problem that the harrowing blade is easy to damage. When the blade 11 of the combined blade 1 of the present embodiment touches the stone, the blade 11 will be pressed over the stone under the traction of the harrow. The combined harrow plate 1 is lifted after the elastic structure is stressed, and the heights of the harrow plate main body 3 and other harrow plates 11 are almost kept unchanged. The pressure applied to the blade 11 contacting the stones is not increased so much, and the blade is not easy to be damaged or bent.

The elastic structure reduces the possibility of damage to the blade 11, which is equivalent to prolonging the service life of the blade 11. And for certain soil with more stones, the farming rake frame of the embodiment can be used for farming. When meeting with some stones which have larger volume and are difficult to turn, the elastic structure plays a role of buffering and damping, and the damage to the harrow plate 11 is reduced. When meeting with some stones with smaller volume, the harrow plate 11 can be directly turned up without affecting the normal harrow. Thus, more complex soils can be harrowed.

It is noted that the farming harrow rack has simple structure and is easy to process and produce. Therefore, the utility model is suitable for popularization and application, and meets the requirements of farmers for ploughing and harrowing.

Further, in the present embodiment, one combined blade 1 is provided with two elastic structures, and this design is only a preferred embodiment in the present embodiment, and should not be taken as a limitation to the present invention. In other cases, the number of the elastic structures can be changed or adjusted according to the use requirement. All changes and adjustments of the number or positions of the elastic structures within the spirit and principle of the present invention should be included in the protection scope of the present invention.

In some embodiments of the present invention, as shown in fig. 2, the combined blade 1 includes a blade 11, a connecting shaft 12 and a supporting member 13, the blade 11 is rotatably connected to the connecting shaft 12, one end of the supporting member 13 is connected to the connecting shaft 12, and the other end of the supporting member 13 is connected to the elastic structure. In the present embodiment, 5 rake blades 11 are fixedly connected to one connecting shaft 12. The combined harrow plate 1 is also provided with a support piece 13 for connecting the elastic structure with the connecting shaft 12, the lower end of the support piece 13 is rotatably connected with the connecting shaft 12, and the upper end of the support piece 13 is fixedly connected with the elastic structure.

It should be noted that, when the supporting member 13 plays a certain supporting role for the elastic structure, the rotation of the connecting shaft 12 is not affected. The number of the blades 11 and the supporting members 13 is only a preferred embodiment in this embodiment, and is not a limitation of the present invention, and other numbers may be selected for installation in other embodiments.

As shown in fig. 3, 4 and 5, the support 13 includes a bearing housing 131, a bearing 132 and an L-shaped support plate 133, the bearing 132 is disposed on the bearing housing 131, the connecting shaft 12 passes through the bearing housing 131 and the bearing 132, one end of the L-shaped support plate 133 is connected to the bearing housing 131, and the other end of the L-shaped support plate 133 is connected to the elastic structure. The support 13 is composed of three parts, a bearing seat 131, a bearing 132 and an L-shaped support plate 133. Wherein the bearing 132 is installed inside the bearing housing 131. The lower end of the L-shaped support plate 133 is fixedly connected with the bearing seat 131, as shown in fig. 5, and the fixed connection mode can be a bolt connection mode (or a welding connection mode according to actual conditions). The top end of the L-shaped supporting plate 133 is fixedly connected with the elastic structure.

To facilitate mounting of the bearing 132, a groove 1311 is provided in the bearing housing 131. The groove 1311 is correspondingly provided with a cover 1312, the bearing housing 131 is provided with a first through hole 1313, the cover 1312 is provided with a second through hole 1314, and the bearing housing 131 and the L-shaped support plate 133 are bolted. The groove 1311 is sized and shaped to fit the bearing 132, the inner race of the bearing 132 and the connecting shaft 12. To confine the bearing 132 within the recess 1311, a cover 1312 is welded to the end of the recess 1311. Meanwhile, in order to facilitate the matching with the connecting shaft 12, the bearing seat 131 is provided with a first through hole 1313, and the cover 1312 is provided with a second through hole 1314. The connecting shaft 12 passes through the first and second through holes 1313 and 1314 and is fixedly connected with the inner race of the bearing 132.

It should be noted that in fig. 4, the bearing 132 is shown as a ball roller bearing, which can be used in case of a lighter rake body 3. If the rake body 3 is heavy, the bearing 132 may be a ball roller bearing or a double-row cylindrical roller bearing with stronger radial bearing force, considering that the radial bearing force of the bearing 132 is larger. Further, instead of using the bearing 132, the connecting shaft 12 may directly rotate in the first through hole 1313 after passing through the bearing seat 131, and some lubricating measures (e.g., applying lubricating oil) may be taken after rotating.

In some embodiments of the present invention, as shown in fig. 6 and 7, the elastic structure includes a plate spring 2, a fixing plate 22 is disposed on the top of the plate spring 2, the fixing plate 22 is bolted to the L-shaped supporting plate 133, and the plate spring 2 includes a spring steel plate 21. As shown in fig. 6, the plate spring 2 is composed of 7 spring steel plates 21 (the number of spring steel plates 21 can be increased or decreased accordingly according to the actual situation). Considering that the plate spring 2 has a good effect of buffering and damping after being stressed, the spring steel plate 21 becomes shorter gradually from top to bottom. Similarly, bolts are adopted to penetrate through the multiple layers of spring steel plates 21 and then nuts are screwed on to realize fixed connection.

In order to facilitate the fixed connection of the plate spring 2 and the L-shaped support plate 133, a fixing plate 22 is provided at a middle position of the top of the plate spring 2. The plate spring 2 is extended from both sides of the fixing plate 22, and the screw of the screw 23 is passed through the fixing plate 22 and the L-shaped support plate 133 and then tightened using a nut to achieve a fixed connection.
