Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a forage turning and drying machine. Background Technology

[0002] In the process of large-scale development of animal husbandry, the drying and storage of forage is a key link in ensuring feed supply and reducing breeding costs. Fresh forage typically has a moisture content of 60%-80% after harvesting. If it is not dried in a timely and effective manner, it is prone to mold growth due to microbial proliferation, resulting in the loss of core nutrients such as protein and vitamins, and even the production of harmful substances that endanger the health of livestock. Therefore, it is necessary to use a forage turning machine to turn the forage.

[0003] In the prior art, such as Chinese Patent Publication No. CN206323817U, a horizontal rotary hay rake (RK) is disclosed, which includes a disc welded part and a spring; the top of the disc welded part is provided with a connecting main welded part, and a first support welded part and a second support welded part are movably connected to one end of the connecting main welded part by bolts; the first support welded part and the second support welded part are connected to the connecting main welded part by a circular bracket welded part, and the suspension pull tube welded part passes through the spring and extends into the spring top tube welded part. This horizontal rotary hay rake, by setting up a first support welded component, a second support welded component, a T-shaped frame connecting plate, upper working teeth, a disc welded component, and a spring jack tube welded component, and the spring jack tube welded component between the disc welded component and the connecting main body welded component, and the upper working teeth on the T-shaped frame connecting plate, ensures that the hay is piled up neatly, is easy to clean, simple to operate, and has high work efficiency, thus solving the problems of single working performance, low productivity, and high missed rake rate of existing hay rakes.

[0004] Although the above-mentioned technical solutions have the above-mentioned technical advantages, their disadvantages are as follows: the working teeth of the above-mentioned patent are designed with a fixed angle, which can only realize the horizontal gathering and planar movement of hay, and cannot complete the dynamic action of "low-position feeding - high-position lifting". It is difficult to turn the bottom layer of damp hay to the surface, and the original stacking state of the hay is not completely broken. The moisture evaporation efficiency is limited, especially in the scenario of turning and drying tall hay (such as alfalfa and sheep grass), which is prone to the problem of "dry outer layer and moldy inner layer", and cannot meet the needs of rapid drying. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a forage turning and drying machine, which solves the problem that the fixed turning angle of existing technologies makes it difficult to turn the bottom layer of damp forage to the surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hay turning and drying machine, comprising a frame, with wheels rotatably connected to the bottom of the frame and a traction hook fixedly connected to the outer side of the frame, and further comprising: a turning component, the top of which is rotatably connected to the bottom of the frame, a drive motor fixedly connected to the top of the frame, and a baffle component fixedly connected to the inner wall of the frame. Power is provided by the drive motor, and by combining the dynamic adjustment of the turning component and the limiting protection of the baffle component, efficient turning and drying of hay can be achieved.

[0007] The turning assembly includes a rotating frame, with a limiting disc rotatably connected to the outer wall of the rotating frame and a limiting cylinder fixedly connected to the inner wall of the rotating frame. A sliding rod is slidably connected to the inner wall of the limiting cylinder, with a tension spring fixedly connected to one end of the sliding rod and a movable rod rotatably connected to the other end. A turning frame is rotatably connected to the bottom end of the movable rod, and a limiting block is fixedly connected to the top of the sliding rod. When the turning frame rotates to the area near the arc-shaped baffle, the limiting block slides along the sliding groove trajectory of the limiting disc. At this time, the top of the movable rod moves synchronously with the sliding rod, thereby pulling the turning frame upward and lifting the pasture previously moved to the designated area, breaking the original stacked state of the pasture, increasing the contact area between the pasture and air and sunlight, and accelerating moisture evaporation.

[0008] Preferably, the top of the rotating frame is fixedly connected to the output end of the drive motor, and the top of the limiting plate is fixedly connected to the bottom of the frame. The output end of the drive motor transmits power to the rotating frame in the material turning assembly, driving the rotating frame to rotate around its own central axis, providing core power for the material turning action.

[0009] Preferably, the bottom of the limiting disc is slidably connected to the top of the limiting block via a sliding groove, and the end of the tension spring away from the sliding rod is fixedly connected to the inner wall of the limiting cylinder. The shape of the limiting disc is similar to that of a cam, and the convex side of its sliding groove trajectory faces the side where the arc-shaped baffle is installed.

[0010] Preferably, the bottom of the limiting cylinder is rotatably connected to the top of the flipping frame, and the limiting cylinder is arranged in a ring along the central axis of the rotating frame. During the rotation of the rotating frame, the limiting cylinder rotates synchronously with the rotating frame, thereby driving the flipping frame to make a circular motion.

[0011] Preferably, the baffle assembly includes an assembly rod, an mounting frame is fixedly connected to the outer side of the assembly rod, and an arc-shaped baffle plate is fixedly connected to the bottom of the mounting frame. The arc-shaped baffle plate, which is fixed to the assembly rod by the mounting frame, is located on one side of the material-dispensing direction of the turning frame. This can effectively prevent the hay that is turned by the turning frame from being thrown away from the working area due to excessive centrifugal force, ensuring that the hay is concentrated in the designated area for drying and avoiding waste caused by the scattering of hay.

[0012] Preferably, a counterweight is fixedly connected to the side of the assembly rod away from the mounting frame, the outer wall of the assembly rod is fixedly connected to the inner wall of the frame, and the weight of the counterweight matches that of the arc-shaped baffle, which can balance the unilateral tension generated by the arc-shaped baffle on the frame and maintain the overall balance of the frame during operation.

[0013] The beneficial effects of this utility model are as follows:

[0014] (i) The hay turning and drying machine is equipped with a turning component. When the turning frame rotates to the area close to the arc-shaped baffle, the limiting block slides along the sliding groove of the limiting plate. The protruding part of the sliding groove generates an outward pushing force on the limiting block, forcing the limiting block to extend outward from the limiting cylinder. At this time, the top of the movable rod moves synchronously with the sliding rod, thereby pulling the turning frame, which is rotatably connected to the bottom of the movable rod, to deflect upward, lifting the hay that was previously moved to the designated area upward, breaking the original stacked state of the hay, increasing the contact area between the hay and the air and sunlight, and accelerating the evaporation of moisture.

[0015] (ii) The hay turning and drying machine is equipped with a baffle assembly. The arc-shaped baffle can prevent the hay that is turned by the turning frame from being thrown away from the working area due to excessive centrifugal force, ensuring that the hay is concentrated in the designated area for turning and drying, and avoiding waste caused by the scattering of hay. The weight of the counterweight is matched with that of the arc-shaped baffle, which can balance the unilateral pulling force generated by the arc-shaped baffle on the frame, maintain the overall balance of the frame during operation, and avoid problems such as uneven force on the traveling wheels and equipment deviation caused by excessive weight on one side.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a hay turning and drying machine, including a frame 1, with a walking wheel 2 rotatably connected to the bottom of the frame 1, and a traction hook 3 fixedly connected to the outer side of the frame 1. It also includes a turning assembly 6, with the top of the turning assembly 6 rotatably connected to the bottom of the frame 1, a drive motor 5 fixedly connected to the top of the frame 1, and a material blocking assembly 4 fixedly connected to the inner wall of the frame 1. At the same time, the drive motor 5 fixedly connected to the top of the frame 1 starts, and its output end transmits power to the rotating frame 61 in the turning assembly 6, driving the rotating frame 61 to rotate around its own central axis, providing the core power for the turning action.

[0023] The material-turning assembly 6 includes a rotating frame 61. A limiting disk 62 is rotatably connected to the outer wall of the rotating frame 61, and a limiting cylinder 63 is fixedly connected to the inner wall of the rotating frame 61. A sliding rod 64 is slidably connected to the inner wall of the limiting cylinder 63. A tension spring 66 is fixedly connected to one end of the sliding rod 64, and a movable rod 67 is rotatably connected to the other end of the sliding rod 64. A material-turning frame 68 is rotatably connected to the bottom end of the movable rod 67. A limiting block 65 is fixedly connected to the top of the sliding rod 64. The top of the rotating frame 61 is fixedly connected to the output end of the drive motor 5. The top of the limiting disk 62 is fixedly connected to the bottom of the frame 1, and the bottom of the limiting disk 62 slides against the top of the limiting block 65 via a sliding groove. The end of the tension spring 66 away from the sliding rod 64 is fixedly connected to the inner wall of the limiting cylinder 63. The bottom of the limiting cylinder 63 is rotatably connected to the top of the turning frame 68. The limiting cylinder 63 is arranged in a ring along the central axis of the rotating frame 61. During the rotation of the rotating frame 61, the limiting cylinder 63 rotates synchronously with the rotating frame 61, thereby driving the turning frame 68 to make a circular motion. At this time, the turning frame 68, which is in a low position, directly contacts the grass on the ground. Through its own rotation, it pushes the grass on the path toward the direction of the baffle assembly 4. The shape of the limiting disc 62 is similar to that of a cam, and the convex side of its slide track faces the side where the arc-shaped baffle plate 43 is installed. When the turning frame 68 rotates to the area close to the arc-shaped baffle plate 43, the limiting block 65 slides along the sliding groove trajectory of the limiting plate 62. The protruding part of the sliding groove exerts an outward pushing force on the limiting block 65, forcing the limiting block 65 to extend outward from the limiting cylinder 63. At this time, the top of the movable rod 67 moves synchronously with the sliding rod 64, thereby pulling the turning frame 68, which is rotatably connected to the bottom of the movable rod 67, to deflect upward, lifting the pasture that was previously moved to the designated area upward, breaking the original stacked state of the pasture, increasing the contact area between the pasture and the air and sunlight, and accelerating the evaporation of moisture.

[0024] When the limiting block 65 slides away from the protruding area of ​​the limiting plate 62, the limiting block 65 is restricted by the shape of the groove in the limiting plate 62 and the rebound force of the tension spring 66. The sliding rod 64 is reset and driven by the movable rod 67 to return the turning frame 68 to the initial low position, preparing for the next round of feeding and lifting actions. This cycle is repeated to achieve continuous turning and drying of the hay.

[0025] The material blocking assembly 4 includes an assembly rod 41, with a mounting frame 42 fixedly connected to the outer side of the assembly rod 41. An arc-shaped material blocking plate 43 is fixedly connected to the bottom of the mounting frame 42. A counterweight block 44 is fixedly connected to the side of the assembly rod 41 away from the mounting frame 42. The outer wall of the assembly rod 41 is fixedly connected to the inner wall of the frame 1. During the material feeding and lifting process of the material turning frame 68, since the arc-shaped material blocking plate 43, which is fixed to the assembly rod 41 by the mounting frame 42, is on one side of the material feeding direction of the material turning frame 68, it can effectively prevent the hay being turned by the material turning frame 68 from being thrown away from the working area due to excessive centrifugal force, ensuring that the hay is concentrated in the designated area for drying and avoiding waste caused by the scattering of hay. The weight of the counterweight block 44 matches that of the arc-shaped material blocking plate 43, which can balance the unilateral pulling force generated by the arc-shaped material blocking plate 43 on the frame 1, maintain the overall balance of the frame 1 during operation, and avoid problems such as uneven force on the traveling wheels 2 and equipment deviation caused by excessive weight on one side.

[0026] This hay turning and drying machine is powered by a drive motor 5. Combined with the dynamic adjustment of the turning component 6 and the limiting protection of the blocking component 4, it achieves efficient turning and drying of hay. The specific working principle is as follows:

[0027] An external traction device (such as a tractor) pulls the entire device via a towing hook 3, causing the traveling wheels 2, which are rotatably connected to the bottom of the frame 1, to roll and move the device along the pasture-laying area. At the same time, the drive motor 5, which is fixedly connected to the top of the frame 1, starts, and its output transmits power to the rotating frame 61 in the turning assembly 6, driving the rotating frame 61 to rotate around its own central axis, providing the core power for the turning action.

[0028] During the rotation of the rotating frame 61, the limiting cylinder 63 rotates synchronously with the rotating frame 61, thereby driving the turning frame 68 to perform a circular motion. At this time, the turning frame 68, which is in a low position, directly contacts the pasture on the ground. Through its own rotation, it pushes the pasture along the path toward the baffle assembly 4. The shape of the limiting disc 62 is similar to that of a cam, with the raised side of its slide groove facing the side where the arc-shaped baffle plate 43 is installed. When the turning frame 68 rotates to the area near the arc-shaped baffle plate 43, the limiting block 65 slides along the slide groove of the limiting disc 62. The raised part of the slide groove exerts an outward pushing force on the limiting block 65, forcing the limiting block 65 to extend outward from the limiting cylinder 63. At this time, the top of the movable rod 67 moves synchronously with the sliding rod 64, thereby pulling the turning frame 68, which is rotatably connected to the bottom of the movable rod 67, upward to deflect it. This lifts the pasture that was previously pushed to the designated area, breaking the original stacked state of the pasture, increasing the contact area between the pasture and the air and sunlight, and accelerating moisture evaporation.

[0029] During the material feeding and lifting process of the material turning frame 68, the arc-shaped baffle plate 43, which is fixed to the assembly rod 41 by the mounting frame 42, is located on one side of the material feeding direction of the material turning frame 68. This effectively prevents the hay being turned by the material turning frame 68 from being thrown away from the work area due to excessive centrifugal force, ensuring that the hay is concentrated in the designated area for drying and avoiding waste caused by the scattering of hay. The counterweight block 44 matches the weight of the arc-shaped baffle plate 43, which can balance the unilateral pulling force generated by the arc-shaped baffle plate 43 on the frame 1, maintain the overall balance of the frame 1 during operation, and avoid problems such as uneven force on the traveling wheels 2 and equipment deviation caused by excessive weight on one side.

[0030] When the limiting block 65 slides away from the protruding area of ​​the limiting plate 62, the limiting block 65 is restricted by the shape of the groove in the limiting plate 62 and the rebound force of the tension spring 66. The sliding rod 64 is reset and driven by the movable rod 67 to return the turning frame 68 to the initial low position, preparing for the next round of feeding and lifting actions. This cycle is repeated to achieve continuous turning and drying of the hay.
