Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a film covering and punching device with adjustable punching size and a film covering and rice transplanting integrated machine. Background Art

[0002] Film covering and transplanting is an extremely critical link in the process of crop planting. The film covering and transplanting machine is an effective tool for executing this link and plays a vital role. When the film covering and transplanting machine is actually used for operation, its significant advantage is that it can efficiently and synchronously complete the two tasks of film covering and transplanting, which greatly improves the planting efficiency and brings convenience to agricultural production. When the film covering work is carried out, after the local film is successfully laid, the punching device is needed to perform the punching work, and then the seedlings are accurately inserted into the punched holes, thereby providing a suitable environment for the growth of the seedlings.

[0003] In the actual planting process, the drilling requirements and quality of the punching device are affected by many factors. For example, the hardness of the plot. When the mulching and transplanting machine works in a plot with softer soil, it sinks more than in a plot with harder soil. At the same time, the soil in the softer plot is more likely to move to the area not affected by gravity after being squeezed by the gravity of the mulching and transplanting machine, resulting in a smaller distance between the soil surface and the mulching film in the planting area and the transplanting machine and the mulching and punching knife, resulting in the size of the holes punched in the mulch film being too large, which not only affects the moisture retention effect of the mulch film, but also easily leads to weed growth in the later planting process. In addition, according to the planting needs, the number of single-hole transplanting and the type of crops planted also have different requirements for the size of the mulching holes. When the number of single-hole transplanting is more, the corresponding holes need to be larger, otherwise they need to be smaller; there are also differences in the growth characteristics and root system requirements of different types of crops, so the size of the holes required is also different.

[0004] However, the existing punching device cannot adjust the size of the holes when used by farmers, which results in the punching device punching too large or too small holes when changing plots for transplanting rice or for planting different crops, affecting the moisture retention effect of the mulch and crop growth. Therefore, it is urgent to design a punching device with adjustable hole size, which can be flexibly adjusted according to actual conditions to meet different soil hardness and different planting needs. Summary of the invention

[0005] In view of the problems that the punching device of the existing film mulching and transplanting machine cannot adjust the size of the holes and cannot adapt to the softness and hardness of soils and different crops, the present invention provides a film mulching and punching device with adjustable hole size and a film mulching and transplanting all-in-one machine. The film mulching and punching device can adjust the distance between the lower end of the punching knife and the ground film by adjusting the distance between the lower edge of the punching knife and the axis of the connecting shaft to adapt to the softness and hardness of different farmland soils; at the same time, the size of the holes of the punching device can be adjusted by adjusting the position of the punching knife to meet different planting needs.

[0006] The technical solution adopted by the present invention is:

[0007] A film covering and punching device with adjustable hole size comprises a plurality of punching knives, a longitudinal connecting plate, a connecting shaft and a driving mechanism. The distance between the lower edge of the punching knife and the axis of the connecting shaft can be adjusted on the longitudinal connecting plate, the longitudinal connecting plate is fixed on the connecting shaft, and the connecting shaft is rotatably installed on a film covering and transplanting machine; the driving mechanism is used to drive the connecting shaft to rotate left and right around its axis.

[0008] Furthermore, the number of punching knives and longitudinal connecting plates is the same, and each punching knife and longitudinal connecting plate has an adjustment slot and a corresponding mounting hole, and the punching knife and the longitudinal connecting plate are detachably connected by bolts passing through the adjustment slot and the mounting hole.

[0009] Furthermore, the number of longitudinal connecting plates is less than the number of punching knives, and several punching knives are fixed on the transverse connecting plates. The transverse connecting plates and the longitudinal connecting plates respectively have adjustment grooves and corresponding mounting holes. The transverse connecting plates and the longitudinal connecting plates are detachably connected by bolts passing through the adjustment grooves and the mounting holes.

[0010] Furthermore, the number of the adjustment slots and the mounting holes is no less than 2.

[0011] Furthermore, the number of punching knives and longitudinal connecting plates is the same, and the side of each punching knife and longitudinal connecting plate is respectively provided with a threaded connecting block and a mounting block at a corresponding position, the threaded rod passes through the connecting shaft, the threaded connecting block, and the mounting block in sequence, and the threaded rod is threadedly connected to the threaded connecting block, and the threaded rod is rotatably connected to the connecting shaft and the mounting block.

[0012] Furthermore, the number of longitudinal connecting plates is less than the number of punching knives, and several punching knives are fixed on the transverse connecting plates. The side surfaces of the transverse connecting plates and the corresponding side surfaces of the longitudinal connecting plates are respectively provided with threaded connecting blocks and mounting blocks. The threaded rod passes through the connecting shaft, the threaded connecting block and the mounting block in sequence, and the threaded rod is threadedly connected to the threaded connecting block, and the threaded rod is rotatably connected to the connecting shaft and the mounting block.

[0013] Furthermore, the bolt head on the threaded rod is located above the connecting shaft.

[0014] Furthermore, the driving mechanism includes a first connecting rod, a second connecting rod, and a power shaft, wherein one end of the first connecting rod is fixed to the connecting shaft, and the other end is hinged to the second connecting rod; one end of the second connecting rod away from the first connecting rod is hinged to the power shaft, and the hinge point between the second connecting rod and the power shaft is eccentrically arranged with respect to the rotation center of the power shaft, and the power shaft is driven by a power source to rotate around the central axis of the power shaft;

[0015] A shaft sleeve is arranged between the connecting shaft and the film covering and transplanting integrated machine, and the connecting shaft and the shaft sleeve can rotate relatively.

[0016] Furthermore, the number of the longitudinal connecting plates is 2-3 and they are arranged at equal intervals.

[0017] A film covering and rice transplanting integrated machine comprises the film covering and punching device with adjustable punching size.

[0018] The beneficial effects of the present invention are:

[0019] The punching device of the present invention can adjust the distance between the lower edge of the punching knife and the axis of the connecting shaft, and then adjust the distance between the lower end of the punching knife and the ground film, so as to adapt to the hardness of different farmland soils, avoid the hardness of farmland affecting the punching effect, and then avoid affecting the later crop planting effect. At the same time, the position of the punching knife can also be adjusted to meet different planting needs. When a larger hole needs to be punched, the punching knife is adjusted downward to increase the distance between the lower end of the punching knife and the axis of the connecting shaft, so that the swing radius of the lower end of the punching knife is increased, and then the size of the punched hole is increased.

[0020] In the present invention, the punching knife is a component that directly contacts the ground film. Directly adjusting the position of the punching knife can also more intuitively and clearly show the effect after adjustment, which makes it easy for users to make adjustments, such as adjusting the size of the punched hole.

[0021] The method for adjusting the position of the punching knife in the present invention is to adjust the position of the punching knife through a bolt or a threaded rod, which is simple to operate. In addition, when a number of punching knives are fixed to the lower end of the transverse connecting plate, the position of all the punching knives on the transverse connecting plate can be adjusted by adjusting the position of the transverse connecting plate at the same time, without the need to adjust the position of each punching knife separately, thereby simplifying the operation.

DETAILED DESCRIPTION

[0031] The present invention will be further described in detail below with reference to the specific implementation modes of the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0032] Embodiment 1

[0033] Figure 1-2 This is an embodiment of the film punching device with adjustable punching size described in the present invention, and the punching device includes a plurality of punching knives 1, longitudinal connecting plates 2, connecting shafts 5, and a driving mechanism. The punching knives 1 and longitudinal connecting plates 2 are of the same number and are arranged correspondingly, and each punching knives 1 and longitudinal connecting plates 2 respectively have an adjustment slot 32 and a corresponding mounting hole, that is, the adjustment slot 32 and the mounting hole on the corresponding punching knives 1 and longitudinal connecting plates 2 work in coordination, and the punching knives 1 and longitudinal connecting plates 2 are detachably connected by bolts 31 that penetrate the adjustment slot 32 and the mounting hole. The relative position of the punching knives 1 and the longitudinal connecting plates 2 can be adjusted by adjusting the position of the bolts 31 on the adjustment slot 32, that is, the punching knives 1 can be adjustably mounted on the longitudinal connecting plates 2. The number of the adjustment slots 32 and the mounting holes is not less than 2, and in this embodiment, the number is 2, so that there are multiple connection points after the punching knives 1 and the longitudinal connecting plates 2 are connected by bolts 31, which increases the stability of the two after the connection. The longitudinal connecting plate 2 is fixed on the connecting shaft 5, and the connecting shaft 5 is rotatably installed on the film covering and transplanting machine. In a specific embodiment, a shaft sleeve 6 is arranged between the connecting shaft 5 and the film covering and transplanting machine. The shaft sleeve 6 is fixedly or rotatably connected to the film covering and transplanting machine. The connecting shaft 5 and the shaft sleeve 6 can rotate relative to each other, so that the connecting shaft 5 can rotate relative to the film covering and transplanting machine, and then the punching knife 1 and the longitudinal connecting plate 2 can swing around the axis of the connecting shaft 5.

[0034] The driving mechanism is used to drive the connecting shaft 5 to rotate left and right around its axis, thereby driving the punching knife 1 to swing left and right around the axis of the connecting shaft 5. Figure 1 The direction of the arrow above the middle connecting shaft 5 indicates the rotation direction of the connecting shaft 5; during the swinging process of the punching knife 1, when the punching knife 1 swings downward, the lower end of the punching knife 1 punches holes in the ground film. The driving mechanism includes a first connecting rod 7, a second connecting rod 8, and a power shaft 9. One end of the first connecting rod 7 is fixed to the connecting shaft 5, and the other end is hinged to the second connecting rod 8; the end of the second connecting rod 8 away from the first connecting rod 7 is hinged to the power shaft 9, and the hinge point 81 between the second connecting rod 8 and the power shaft 9 is eccentric to the rotation center of the power shaft 9. The power shaft 9 is driven by a power source to rotate around the center axis of the power shaft 9, and the power source can be a motor. Figure 1 As shown, since the hinge point 81 is eccentric to the rotation center of the power shaft 9, when the power source drives the power shaft 9 to rotate around its central axis, the hinge point 81 rotates around the central axis of the power shaft 9, and the second connecting rod 8 drives the first connecting rod 7 to rotate around the axis of the connecting shaft 5, thereby driving the punching knife 1 to swing left and right around the axis of the connecting shaft 5 to punch holes in the ground film. Before the film covering and transplanting machine works, the relative positions of the punching knife 1 and the longitudinal connecting plate 2 can be adjusted by bolts 31 according to the hardness of the soil and different planting requirements, thereby adjusting the distance between the lower end of the punching knife 1 and the axis of the connecting shaft 5. When the film covering and transplanting machine needs to work on softer farmland soil, considering that the film covering and transplanting machine will sink more on farmland with softer soil than on farmland with harder soil, the distance between the film covering and transplanting machine and the ground film on the farmland surface will become smaller. Therefore, the punching knife 1 is adjusted upward by bolt 31 to avoid that the distance between the punching knife 1 and the ground film is not too small, so that the punching effect meets the requirements. In addition, the size of the hole can be adjusted according to different planting needs. Specifically, when a larger hole needs to be punched, the punching knife 1 is adjusted downward to increase the distance between the lower end of the punching knife 1 and the axis of the connecting shaft 5, so that the swing radius of the lower end of the punching knife 1 is increased, thereby increasing the size of the punched hole; otherwise, the punching knife 1 is adjusted upward to reduce the size of the punched hole. And as a component that directly contacts the ground film, directly adjusting the position of the punching knife 1 can also more intuitively and clearly show the effect after adjustment, which makes it easy for users to adjust the size of the punched hole.

[0035] Embodiment 2

[0036] Figure 3-4The schematic diagram of the second structure of the film punching device with adjustable punching size of the present invention is shown in the figure. The difference between the second embodiment and the first embodiment is that the number of the longitudinal connecting plates 2 is less than the number of the punching knives 1, and the plurality of punching knives 1 are fixed on the transverse connecting plate 11. The transverse connecting plate 11 and the longitudinal connecting plate 2 respectively have adjustment slots 32 and corresponding mounting holes. The transverse connecting plate 11 and the longitudinal connecting plate 2 are detachably connected by bolts 31 penetrating the adjustment slots 32 and the mounting holes. The relative positions of the transverse connecting plate 11 and the longitudinal connecting plate 2 can be adjusted by adjusting the position of the bolts 31 on the adjustment slots 32, and the relative positions of all the punching knives 1 and the longitudinal connecting plate 2 on the transverse connecting plate 11 can be uniformly adjusted. The number of the longitudinal connecting plates 2 is 2-3, which are arranged at equal intervals. The longitudinal connecting plates 2 are located at both ends of the transverse connecting plate 11 or at both ends and in the middle of the transverse connecting plate 11. Compared with the first embodiment, the position of the punching knives 1 can be adjusted by adjusting the position of the transverse connecting plate 11 to reduce the number of adjustments, and there is no need to adjust the position of each punching knife 1 separately, which simplifies the operation. The number of the adjustment slots 32 and the mounting holes is not less than 2, and in this embodiment, the number is 2, so that after the horizontal connecting plate 11 and the longitudinal connecting plate 2 are connected by bolts 31, there are multiple connection points, which increases the stability of the two after the connection. The rest of the structure of the second embodiment is the same as that of the first embodiment. The second embodiment can also adjust the position of the punching knife 1 by adjusting the bolts 31, thereby adapting to different hard and soft soils and meeting different planting needs.

[0037] Embodiment 3

[0038] Figure 5-6 This is a schematic diagram of the third structure of the film punching device with adjustable punching size described in the present invention. The difference between the third embodiment and the first embodiment is that: the number of punching knives 1 and longitudinal connecting plates 2 is the same, and the side of each punching knives 1 and longitudinal connecting plate 2 is respectively provided with a threaded connection block 12 and a mounting block 21 at a corresponding position, that is, the threaded connection block 12 and the mounting block 21 are arranged correspondingly. The threaded rod 4 passes through the connecting shaft 5, the threaded connection block 12, and the mounting block 21 in sequence, and the threaded rod 4 is threadedly connected to the threaded connection block 12, and the threaded rod 4 is rotatably connected to the connecting shaft 5 and the mounting block 21. The position of the threaded connection block 12 can be adjusted by rotating the threaded rod 4, and then the punching knives 1 can be adjusted, that is, the punching knives 1 can be adjusted to the longitudinal connecting plate 2. And the bolt head 41 on the threaded rod 4 is located above the connecting shaft 5, so that it is convenient to use a tool to tighten the bolt head 41 and then rotate the threaded rod 4, such as using a wrench to tighten the bolt head 41.

[0039] Similarly, the longitudinal connecting plate 2 is fixed on the connecting shaft 5, and the connecting shaft 5 is rotatably mounted on the film covering and transplanting machine. Specifically, a shaft sleeve 6 is provided between the connecting shaft 5 and the film covering and transplanting machine, and the shaft sleeve 6 is fixedly or rotatably connected to the film covering and transplanting machine. The connecting shaft 5 and the shaft sleeve 6 can rotate relative to each other, so that the connecting shaft 5 can rotate relative to the film covering and transplanting machine, and then the punching knife 1 and the longitudinal connecting plate 2 can swing around the axis of the connecting shaft 5. In addition, the driving mechanism in the third embodiment is the same as that in the first embodiment, and is used to drive the connecting shaft 5 to rotate left and right around its axis.

[0040] When the position of the punching knife 1 needs to be adjusted, the bolt head 41 is turned to rotate the threaded rod 4, so that the threaded connection block 12 moves up and down along the threaded rod 4, thereby adjusting the position of the punching knife 1 to adapt to the hardness of different farmland soils, or adjusting the size of the holes to meet different planting needs.

[0041] Embodiment 4

[0042] Figure 7-8 This is a schematic diagram of the fourth structure of the film punching device with adjustable punching size described in the present invention. The difference between the fourth embodiment and the third embodiment is that the number of longitudinal connecting plates 2 is less than the number of punching knives 1. The number of longitudinal connecting plates 2 is 2-3, which are arranged at equal intervals. The longitudinal connecting plates 2 are located at both ends of the transverse connecting plate 11 or at both ends and the middle of the transverse connecting plate 11. Several punching knives 1 are fixed on the transverse connecting plate 11. The side of the transverse connecting plate 11 and the side corresponding to the longitudinal connecting plate 2 are respectively provided with a threaded connection block 12 and a mounting block 21. The threaded rod 4 passes through the connecting shaft 5, the threaded connection block 12, and the mounting block 21 in sequence. The threaded rod 4 is threadedly connected with the threaded connection block 12, and the threaded rod 4 is rotatably connected with the connecting shaft 5 and the mounting block 21. The bolt head 41 on the threaded rod 4 is located above the connecting shaft 5, so as to facilitate the use of a tool to tighten the bolt head 41 and then rotate the threaded rod 4, such as using a wrench to tighten the bolt head 41. In this embodiment, the position of the transverse connecting plate 11 can be adjusted by rotating the threaded rod 4, thereby uniformly adjusting the positions of all the punching knives 1 on the transverse connecting plate 11. Compared with the third embodiment, it is not necessary to adjust the position of each punching knife 1 separately, which simplifies the operation. The remaining structure of the fourth embodiment is the same as that of the third embodiment. The fourth embodiment can also adjust the position of the punching knife 1 by adjusting the threaded rod 4, thereby adapting to different hard and soft soils and meeting different planting needs.
