Description

Technical Field

[0001] This utility model belongs to the technical field of grass planter components, and in particular relates to the rake tooth mounting structure for grass planters. Background Technology

[0002] A hay fork is a type of machinery mainly used in agriculture for collecting, transporting, and stacking hay. The fork teeth are the key components of the hay fork, usually composed of multiple metal forks. The forks are generally quite thick and have a certain degree of curvature to better insert into and lift hay piles. In agricultural production, the use of hay fork plays an important role in some agricultural operations (such as planting hay and laying hay).

[0003] The rake teeth of a hay planter are usually installed and fixed with U-bolts. The installation firmness depends on the tightness of the U-bolt clamp. However, the U-bolt clamps the fence plate in a planar manner, which cannot effectively limit the lateral direction of the rake teeth. In addition, the spacing of some rake teeth is fixed, making it difficult to flexibly adjust the spacing according to different operational needs. Therefore, it is necessary to provide a rake tooth installation structure for hay planters, which adopts a rotating clamping fixing structure to enhance the lateral and longitudinal resistance strength, while the spacing is adjustable, so as to cope with the moving operation of different hay bales.

[0021] In the following description, embodiments of the rake tooth mounting structure for a grass planter according to the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a rake tooth mounting structure for a grass planter according to an embodiment of the present invention, comprising positioning sleeves 3 sleeved on both sides of the surface of a support arm 1; a fence 2 welded to the top of the support arm 1; a rotating sleeve 4 rotatably connected to the inner cavity of the positioning sleeve 3; limit sliders 9 welded to both sides of the top of the rotating sleeve 4; and limit grooves 10 adapted to the limit sliders 9 on both sides of the top of the positioning sleeve 3. Through the cooperation of the limit sliders 9 and the limit grooves 10, the rotating sleeve 4 is limited and guided, thereby ensuring that the rotating sleeve 4 is stably positioned within the inner cavity of the positioning sleeve 3 and improving the stability of the rotating sleeve 4 during rotation. A connecting plate 5 is fixedly connected to the rear side of the rotating sleeve 4, and rake teeth 7 are provided on the rear side of the connecting plate 5. Four second bolts 12 are inserted through the front end of the rake teeth 7, and the rake teeth 7 and the connecting plate 5 are fixedly connected by the second bolts 12. Adjustment components 8 are provided on both sides of the surface of the support arm 1, and the adjustment components 8 include limit blocks 81 welded to the top of the inner cavity of the rotating sleeve 4. Both sides of the surface of arm 1 are provided with rectangular grooves 82 that are adapted to the limiting block 81. Both sides of the surface of support arm 1 are provided with multiple limiting grooves 83 that are connected to the rectangular grooves 82. The rear side of the positioning sleeve 3 is provided with an arc-shaped hole 6. The connecting plate 5 is slidably connected to the inner cavity of the arc-shaped hole 6. The front side of the positioning sleeve 3 is provided with an arc-shaped groove 84. The top of the rotating sleeve 4 is welded with a tension spring 85. The bottom end of the tension spring 85 is welded to the inner wall of the arc-shaped groove 84. Through the matching of the arc-shaped groove 84 and the tension spring 85, When used together, it provides elastic pulling for the rotating sleeve 4 and the connecting plate 5, thereby assisting the user in flipping the rake teeth 7, so that the limiting block 81 can enter the inner cavity of the rectangular slide groove 82, and the position of the rotating sleeve 4 and the connecting plate 5 on the surface of the support arm 1 can be adjusted. The limiting block 81 is engaged in the inner cavity of the limiting groove 83. Two first bolts 11 are provided through both sides of the bottom of the positioning sleeve 3, and multiple threaded grooves that match the first bolts 11 are opened on both sides of the bottom of the support arm 1.

[0023] Working principle: When using this utility model, the user fixes the front end of the rake tooth 7 to the rear side of the connecting plate 5 using the second bolt 12. Then, the user holds the rake tooth 7 and rotates it upwards, causing the connecting plate 5 to rotate within the inner cavity of the arc-shaped hole 6. During the rotation of the connecting plate 5, the rotating sleeve 4 rotates within the inner cavity of the positioning sleeve 3, and simultaneously the limiting slider 9 rotates within the inner cavity of the limiting groove 10. After the connecting plate 5 rotates to the top of the inner cavity of the arc-shaped hole 6, the limiting block 81 exits the limiting groove 8. The inner cavity of 3 enters the inner cavity of the rectangular slide groove 82. Then, the user pushes the positioning sleeve 3 at the top of the support arm 1 so that the positioning sleeve 3 reaches the specified distance position. Then, the user slowly lowers the rake tooth 7 so that the rotating sleeve 4 rotates in the inner cavity of the positioning sleeve 3, thereby allowing the limiting block 81 to engage in the inner cavity of the current limiting slot 83. Then, the user screws the first bolt 11 into the bottom of the positioning sleeve 3 and makes the first bolt 11 threadedly connected to the surface of the support arm 1.

[0024] In summary, the rake tooth mounting structure used in this grass planter, through the coordinated use of the positioning sleeve 3, the rotating sleeve 4, and the connecting plate 5, allows the rake teeth 7 to be stably installed on the rear side of the support arm 1. At the same time, through the coordinated use of the rotating sleeve 4 and the spacing adjustment component 8, the distance between the two rake teeth 7 can be quickly and accurately adjusted, thus achieving the purpose of adjustable rake tooth spacing, precise spacing adjustment, and secure installation.
