Description

Technical Field

[0001] This utility model belongs to the technical field of hay rakes, specifically relating to a hay rake with adjustable finger height from the ground. Background Technology

[0002] In modern forage harvesting operations, hay rakes are key pieces of equipment, and their operational quality directly affects the efficiency and quality of hay collection, as well as subsequent processing and utilization. Precise adjustment of the hay rake's handle height is one of the core elements ensuring effective operation.

[0003] A patent search revealed that Chinese patent application number CN202223361440.9 discloses a hay rake with adjustable finger height. This patent allows for easy adjustment of the finger height, reducing premature wear or deformation of the finger and affecting the quality of the harvested hay.

[0004] However, this hay rake cannot flexibly adapt to the hay-raking needs of different terrains. For example, when used on uneven ground, if all the fingers are adjusted to the same height, the fingers are prone to sinking into the depressions when encountering potholes, which can easily cause the fingers to deform under stress and make it difficult to adapt to the terrain for hay-raking. Utility Model Content

[0005] The purpose of this invention is to provide a hay rake with an adjustable finger rod height from the ground, which can use an elastic rod to rake hay on uneven ground, preventing deformation caused by hard contact between the lever and the ground depression, thereby improving its adaptive performance.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A hay rake with adjustable finger height from the ground includes a transmission box. A bushing is fixedly connected to the side wall of the transmission box, and a bracket is fixedly connected to the side wall of the bushing. Multiple crossbeams are fixedly connected to the bottom surface of the transmission box. Connecting parts are assembled on the side walls of the crossbeams, and connecting plates are assembled on the side walls of the connecting parts. Lifting components are provided on the side walls of the connecting plates. Straight plates are provided on the lower side of each crossbeam, and levers are fixedly connected to the bottom surface of each straight plate. Elastic rods are provided at the bottom ends of each lever.

[0008] Furthermore, the connector includes a mounting plate fitted onto the side wall of the crossbeam, the mounting plate being U-shaped.

[0009] Furthermore, the mounting plate has two bolts fitted to its side wall.

[0010] Furthermore, the lifting assembly includes a sleeve fixedly connected to the side wall of the connecting plate, a handwheel threadedly connected to the side wall of the sleeve, a lifting rod disposed inside the sleeve, the bottom end of the lifting rod being fixedly connected to the straight plate, and multiple screw holes being opened on the side wall of the lifting rod, with the handwheel being adapted to the screw holes.

[0011] Furthermore, the elastic rod includes a support plate fixedly connected to the bottom end of the lever. The support plate is U-shaped, and a movable rod is provided on the inner side of the support plate. A rotating shaft is fixedly connected to the side wall of the movable rod, and the other end of the rotating shaft is rotatably connected to the support plate. A torsion spring is assembled on the side wall of the rotating shaft.

[0012] Furthermore, both the lever and the movable lever are arc-shaped structures.

[0013] Furthermore, the radius of the movable lever is greater than that of the lever.

[0014] The technical effects achieved by this utility model are as follows:

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-3As shown, a hay rake with adjustable finger height from the ground includes a transmission box 1. The bottom of the transmission box 1 can be equipped with movable wheels (not shown in the figure), which are prior art. A bushing 2 is fixedly connected to the side wall of the transmission box 1, and a bracket 3 is fixedly connected to the side wall of the bushing 2. Multiple crossbeams 4 are fixedly connected to the bottom surface of the transmission box 1. Connecting parts are assembled on the side walls of the crossbeams 4, and connecting plates 6 are assembled on the side walls of the connecting parts. Lifting components are provided on the side walls of the connecting plates 6. Straight plates 9 are provided on the lower side of each crossbeam 4, and levers 10 are fixedly connected to the bottom surface of each straight plate 9. Each lever 10 has an elastic rod at its bottom end.

[0023] like Figure 2 As shown, the connector includes a U-shaped mounting plate 5 that fits onto the side wall of the crossbeam 4. Two bolts 17 are fitted onto the side wall of the mounting plate 5. In practical applications, multiple sets of levers 10 can be installed on a single crossbeam 4 according to hay-gathering requirements. Simply fitting the mounting plate 5 onto the crossbeam 4 and tightening the bolts 17 completes the locking process. The structure is simple, the operation is convenient, and the stability is high.

[0024] like Figure 2 As shown, the lifting assembly includes a sleeve 7 fixedly connected to the side wall of the connecting plate 6. A handwheel 11 is threadedly connected to the side wall of the sleeve 7. A lifting rod 8 is provided inside the sleeve 7. The bottom end of the lifting rod 8 is fixedly connected to the straight plate 9. Multiple screw holes 12 are opened on the side wall of the lifting rod 8. The handwheel 11 is adapted to the screw holes 12.

[0025] When adjusting the height of the lever 10, all levers 10 can be adjusted to a suitable height, or multiple sets of levers 10 can be adjusted to different heights, and can be used selectively according to the terrain. Secondly, the screw holes 12 are evenly spaced, and the spacing can be judged by the number of screw holes 12, so as to facilitate the height adjustment of multiple levers 10.

[0026] like Figure 3 As shown, the elastic rod includes a support plate 13 fixedly connected to the bottom end of the lever 10. The support plate 13 is U-shaped, and a movable rod 15 is provided on the inner side of the support plate 13. A rotating shaft 14 is fixedly connected to the side wall of the movable rod 15. The other end of the rotating shaft 14 is rotatably connected to the support plate 13. A torsion spring 16 is assembled on the side wall of the rotating shaft 14.

[0027] The movable rod 15 serves two purposes: firstly, it protects the lever 10 from hard friction with the ground, preventing deformation and other problems; secondly, the movable rod 15, in conjunction with the torsion spring 16, provides an elastic deflection effect, adapting to the flatness of the ground; and thirdly, after deflection, the movable rod 15 comes into contact with the ground, without affecting the gathering of hay, thus achieving the goal of efficient hay gathering.

[0028] like Figure 2 and Figure 3 As shown, both lever 10 and movable lever 15 are arc-shaped structures. The arc of movable lever 15 is greater than that of lever 10.

[0029] During the hay-gathering process, the hay is first collected on the movable rod 15, then piled up into the lever 10. Then, the centrifugal force during rotation is used to throw the hay to one side. The arc-shaped structure of the lever 10 and the movable rod 15 serves both as a guide and as a means to collect the hay.

[0030] The working principle of this utility model is as follows: When it is necessary to adjust the height of the lever 10, first rotate the handwheel 11 in the reverse direction to disengage it from the screw hole 12. Then, after adjusting the lifting rod 8 to a suitable height, rotate the handwheel 11 in the forward direction to insert it into the corresponding screw hole 12. Then, use the bracket 3 to install the hay rake on the traction device. During the movement, the traction device drives the crossbeam 4 to rotate. The movable rod 15 can gather hay or straw. When there is a lot of hay, the lever 10 is used to gather it. If there are potholes on the ground, the force of the torsion spring 16 is used to make the movable rod 15 deflect and move against the ground without affecting the gathering of hay. When the movable rod 15 enters the flat ground, the torsion spring 16 rebounds and drives the movable rod 15 to return to its original position, thereby increasing the self-adaptive performance when rakes hay.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
