Description

Technical Field

[0001] The utility model relates to the technical field of potato seedling-killing machines, in particular to a novel multifunctional potato seedling-killing machine. Background Art

[0002] During the breeding process, potato crops have the following growth characteristics: tubers are mainly formed underground and are nutrient storage and reproduction organs, that is, the fruit part that can be eaten by humans, while the above-ground part grows fast, with lush branches and leaves, and easily forms a dense plant layer, which affects ventilation and light transmission. Practice has proved that killing seedlings can not only reduce the resistance of excessive potato seedlings to the harvester, but also greatly improve the harvesting efficiency and save costs.

[0003] In order to facilitate the killing of potato seedlings, potato seedling killing machines have begun to appear in the existing technology. Most of these seedling killing machines are hand-held, have a small structure, and have poor seedling killing efficiency. Therefore, seedling killing machines with three-point suspension connections have begun to appear on the market and are used on tractors and other equipment. These seedling killing machines have high working efficiency and can greatly accelerate the efficiency of killing seedlings.

[0004] However, due to the high power of traction equipment such as tractors and the fast seedling killing speed, the plant layer may not be completely broken during the seedling killing process, affecting the subsequent seedling killing efficiency of the seedling killing knife; and a seedling pulling shaft is often required to pull the seedlings before killing, but seedlings that are too long are easily entangled inside the equipment, which not only affects work efficiency but may also cause damage to the equipment.

[0005] Therefore, the existing technology needs to be further improved and enhanced. Utility Model Content

[0006] The purpose of the utility model is to provide a novel multifunctional potato seedling killing machine, which has the characteristics of high seedling killing efficiency, good cutting effect, and reduced seedling entanglement problem.

[0007] To achieve this purpose, the present invention adopts the following technical solutions:

[0008] The present application provides a novel multifunctional potato seedling killing machine, comprising a transmission box and a frame. The seedling killing machine also comprises a seedling picking shaft, a first seedling killing shaft and a second seedling killing shaft arranged in the frame. The three are arranged in sequence. The transmission box is arranged on the side wall of the frame and is connected to the seedling picking shaft, the first seedling killing shaft and the second seedling killing shaft. The surface of the seedling picking shaft is provided with a seedling picking rod, and the first seedling killing knife is arranged at intervals between the seedling picking rods. The second seedling killing knife is fixedly arranged on the surface of the first seedling killing shaft, and the third seedling killing knife is rotatably arranged on the surface of the second seedling killing shaft.

[0009] Furthermore, the first rice seedling-killing knife includes a support rod and a horizontal blade. The horizontal blade is arranged on the top of the support rod and is staggered with the rice seedling-picking rod.

[0010] Furthermore, the third rice seedling-killing knife includes a fixed plate and rice seedling-killing teeth. The fixed plate is provided with a rotation groove, and the rotation groove is rotatably connected to one side of the rice seedling-killing teeth.

[0011] Furthermore, the rotation radius of the rice seedling-killing teeth is smaller than the gap between the first rice seedling-killing shaft and the second rice seedling-killing shaft.

[0012] Furthermore, connecting rods are provided on both sides of the first seedling-killing shaft, the second seedling-killing shaft and the seedling-lifting shaft, and both sides of the connecting rods are connected to the inner side walls of the frame.

[0013] Furthermore, a power box is provided at the rear end of the frame, the power box is provided with a three-point suspension installation position, a driving shaft is provided on one side of the power box, and a driven shaft is vertically provided on the side wall.

[0014] Furthermore, a linkage box is provided on the side opposite to the transmission box, and a first transmission chain is provided in the linkage box. The first transmission chain connects the driven shaft, the second rice-killing shaft and the first rice-killing shaft.

[0017] The technical solution provided by the utility model may have the following beneficial effects:

[0018] The utility model provides a novel multifunctional potato seedling killing machine, which is provided with three shafts, including two seedling killing shafts. Compared with the equipment in the prior art which generally has only one seedling killing shaft, the two seedling killing shafts of the present application can cooperate with each other to improve the cutting ability of potato seedlings, and by arranging a first seedling killing knife and a seedling picking rod on the surface of the seedling picking shaft, the potato seedlings can be preliminarily cut while the seedlings are being picked.

[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish between the described features, without distinction of order or importance.

[0029] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] The following combination Figures 1 to 4 , describing a new multifunctional potato seedling killing machine provided by an embodiment of the present invention, including a transmission box 10 and a frame 20. The seedling killing machine also includes a seedling picking shaft 21, a first seedling killing shaft 22 and a second seedling killing shaft 23 arranged in the frame 20. The three are arranged in sequence. The transmission box 10 is arranged on the side wall of the frame 20 and is connected to the seedling picking shaft 21, the first seedling killing shaft 22 and the second seedling killing shaft 23. A seedling picking rod 212 is provided on the surface of the seedling picking shaft 21, and a first seedling killing knife 211 is provided between the seedling picking rods 212. The second seedling killing knife 221 is fixedly provided on the surface of the first seedling killing shaft 22, and the third seedling killing knife 231 is rotatably provided on the surface of the second seedling killing shaft 23.

[0032] Among them, such as Figure 1 As shown, the outer shell of the frame 20, the structure of the transmission box 10, and the setting positions of the two can be similar to the structures of the existing technology CN110226402A potato seedling killing machine, CN109566053A knife-type potato seedling killing machine, etc., and the common setting method and appearance shape of the existing technology can reduce the production cost and improve the processing efficiency.

[0033] In addition, for the rice seedling picking rod 212, as Figure 2 As shown, it can adopt a structure similar to a curved hook to pick up the potato vines raised on the ground, so as to facilitate the subsequent first vine-killing shaft 22 and the second vine-killing shaft 23 to kill the vines.

[0034] Among them, such as Figure 2 As shown, the first rice seedling-killing knife 211 includes a support rod 213 and a horizontal blade 214. The horizontal blade 214 is arranged at the top of the support rod 213 and is staggered with the rice seedling-lifting rod 212. That is to say, the support rod 213 and the horizontal blade 214 are combined into a T-shaped cutting knife structure, which can not only increase the cutting area through the horizontal blade 214, but also cut more plants per unit time and improve work efficiency; and the support rod 213 can give the horizontal blade 214 a certain height, so that it can adapt to the shape of plants, such as upright, oblique, curved, etc., thereby improving the scope of application.

[0035] Of course, the horizontal length of the horizontal blade 214 should not be greater than the distance between the rice seedling lifting rods 212. On the one hand, it ensures the initial cutting effect of the rice seedlings lifted by the rice seedling lifting rods 212, and on the other hand, it reduces the collision between the two and ensures safe and reliable use.

[0036] As for the number of settings, multiple first rice seedling-killing knives 211 can be set on the surface of the rice seedling-picking shaft 21, or a longer first rice seedling-killing knife 211 can be set in the middle area. Both settings can play a good role in picking rice seedlings and assisting in killing rice seedlings.

[0037] Furthermore, if Figure 2 As shown, the third rice seedling-killing knife 231 includes a fixed plate 232 and a rice seedling-killing tooth 233 . The fixed plate 232 is provided with a rotation groove, which is rotatably connected to one side of the rice seedling-killing tooth 233 .

[0038] For the structure of the rotating groove and the killing teeth 233, both can adopt the structure similar to the fling knife in the prior art, such as Figure 2 As shown, a hinge position is provided in the rotating groove of the fixed plate 232, and the killing teeth 233 can be hingedly set at the hinge position. When the second killing shaft 23 rotates, the killing teeth 233 can swing along the rotation direction to perform rapid cutting, which can reduce direct contact with the plants, reduce the wear of the tool, extend the service life of the tool and thus improve the cutting effect. Moreover, when swinging again, the position of the killing teeth 233 changes continuously, which can play a certain role in adjusting the cutting depth and angle, so as to further improve the cutting accuracy and ensure the killing effect.

[0039] Specifically, the rice seedling-killing teeth 233 can adopt a Y-shaped structure, one end of which is connected to the rotating groove, and the other end extends obliquely to both sides to form a Y-shaped structure. This structure can also increase the cutting area and increase the rice seedling-killing efficiency.

[0040] Of course, the second seedling-killing knife 221 set on the surface of the second seedling-killing shaft 23 can also adopt a Y-shaped structure, or it can be directly set with multiple vertical blades to cut the potato seedlings. The rotation radius of the seedling-killing teeth 233 is smaller than the gap between the first seedling-killing shaft 22 and the second seedling-killing shaft 23, which can further cut and crush the remaining plants while reducing the influence between the two to ensure the seedling-killing effect.

[0041] As a preferred embodiment of the present application, Figure 2 As shown, the first rice seedling-killing shaft 22, the second rice seedling-killing shaft 23 and the rice seedling-lifting shaft 21 are provided with connecting rods on both sides, and the two sides of the connecting rods are connected to the inner side walls of the frame 20, so that the first rice seedling-killing shaft 22, the second rice seedling-killing shaft 23 and the rice seedling-lifting shaft 21 are positioned between the two inner side walls of the frame 20.

[0042] Furthermore, if Figure 3 As shown, a power box 11 is provided at the rear end of the frame 20, and the power box 11 is provided with a three-point suspension mounting position 32. A driving shaft is provided on one side of the power box 11, and a driven shaft is provided vertically on the side wall. The three-point suspension mounting position 32 can be provided in the top area of the power box 11 to cooperate with the driving shaft, so that the frame 20 can be connected to a four-wheel tractor or other four-wheel transport equipment, providing power to the entire rice seedling killing machine while driving the first rice seedling killing shaft 22, the second rice seedling killing shaft 23 and the rice seedling lifting shaft 21 to move.

[0043] Furthermore, if Figure 1 and Figure 3 As shown, a linkage box 12 is provided on the opposite side of the transmission box 10, and a first transmission chain 13 is provided in the linkage box 12. The first transmission chain 13 connects the driven shaft, the second rice seedling killing shaft 23 and the first rice seedling killing shaft 22. A second transmission chain 14 is provided in the transmission box 10, and the second transmission chain 14 connects the second rice seedling killing shaft 23, the first rice seedling killing shaft 22 and the rice seedling picking shaft 21.

[0044] It can be understood that the first transmission chain 13 and the second transmission chain 14 can adopt a chain structure or a transmission belt structure. In order to ensure the transmission of power, the second seedling-killing shaft 23, the first seedling-killing shaft 22 and the seedling-picking shaft 21 and other power shafts need to be provided with matching pulleys or sprockets. For the power connection of the first transmission chain 13 and the second transmission chain 14, it can adopt a connection method similar to that in the prior art, such as the CN215379923U hand-held seedling-killing machine, the CN109566053A knife-throwing potato seedling-killing machine or the CN110226402A seedling-killing machine. Similar transmission structures, therefore, this application will no longer elaborate on the transmission method and the connection method. As long as the setting method can transmit the power of the driven wheel to the second seedling-killing shaft 23, the first seedling-killing shaft 22 and the seedling-picking shaft 21, this application can use it.

[0045] As a preferred embodiment of the present application, Figure 3 and Figure 4 As shown, the frame 20 includes a frame body 20 and a cover body 30. The top wall of the frame body 20 is hingedly provided with an opening and closing cover, and the bottom of the frame body 20 is provided with a moving wheel 31; wherein, a shock absorber can be provided at the driven wheel.

[0046] Other structures and operations of the new multifunctional potato seedling-killing machine according to the embodiment of the present invention are known to ordinary technicians in this field and will not be described in detail here.

[0047] Throughout this specification, references to terms such as "embodiment" and "example" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example.
