Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and specifically relates to a film installation mechanism for rice transplanting. Background Art

[0002] With the development of technology, there are various rice varieties, including an organic rice variety. Organic rice is generally planted in the western and northern regions. During the planting process of organic rice, herbicides cannot be used, and only manual weeding can be carried out. One person can only manage one or two mu of fields.

[0003] When farmers plant organic rice, a large amount of weeds will grow in the paddy fields. These weeds will affect the growth of rice. Therefore, before planting rice, a plastic film will be laid on the soil surface first. The plastic film is the ground covering film. Cover the soil with the plastic film and then irrigate with water to prevent the growth of weeds. Moreover, covering the plastic film can increase and maintain the temperature, promote the growth of rice, and increase the yield.

[0004] In rural areas of our country, farmers usually carry out farming in family units and it is difficult to bear the cost of high-priced agricultural machinery and equipment. In terms of the laying of plastic films, in the past, the two ends of the plastic film were held by both arms, bending the body and walking backwards on the ridge, which was extremely tiring. Since it is all manual work, the work efficiency is low and the labor intensity is high. Summary of the Invention

The outermost two plow blades are connected with a tensile force sensing unit. A blocking net is formed by the plow blade and the steel wire. According to whether the tensile force sensing unit is subjected to tensile force, it is judged whether there are stone particles on the soil surface. Then, through the cooperation of a connecting block and a roller, the rotating rod is driven to rotate to lift the blocking net, so as to throw the stone particles forward and make the stone particles away from the plastic film.

Detailed implementation manner

[0041] An embodiment of the present invention provides a plastic film installation mechanism for rice transplanting. In Embodiment 1, as Figures 1-3 shown, install the plastic film horizontal pipe below the rice transplanter, and the plastic film is wound around the plastic film horizontal pipe, including a cross beam rod 1. The left end of the top of the cross beam rod 1 is connected to a first connecting piece, and the right end of the cross beam rod 1 is connected with a positioning mechanism. The top of the cross beam rod 1 is symmetrically connected with second connecting pieces, and the second connecting pieces are used to connect with the bottom of the rice transplanter. The length of the cross beam rod 1 is greater than the width of the rice transplanter.

[0042] The first connecting piece can be a sleeve 11, and the second connecting piece can be an iron block 12. The sleeve 11 is pivotally connected to the left end of the cross beam rod 1, and the iron block 12 is welded to the top of the cross beam rod 1. The iron block 12 is welded to the bottom of the rice transplanter, so that the cross beam rod 1 is located between the front wheel and the rear wheel of the rice transplanter.

[0043] The positioning mechanism can be composed of a collar 13, a fixing ring 2, a first screw rod 21 and an air ring 23. The collar 13 is welded to the right end of the cross beam rod 1, and an annular groove is opened inside the collar 13. A plurality of support rods 22 are fixedly installed between the fixing ring 2 and the air ring 23, and the air ring 23 can be embedded in the groove of the collar 13.

[0044] During work, pass the plastic film horizontal pipe through the collar 13, insert the left end of the plastic film horizontal pipe into the sleeve 11, then put the fixing ring 2 on the outside of the right end of the plastic film horizontal pipe, thread the first screw rod 21 through the fixing ring 2 and the right end of the plastic film horizontal pipe. After the air ring 23 is aligned with the groove of the collar 13, inflate the inside of the air ring 23. After the air ring 23 bulges, the air ring 23 is buckled with the groove, so as to achieve the effect of fixing the plastic film horizontal pipe. The overall structure is simple, the installation and disassembly are more convenient, and the maintenance cost is further reduced.

[0045] Embodiment 2, as Figures 4-10 shown:

[0046] The second connector can be a connecting block 3, the upper end of which is welded to the bottom of the rice transplanter. A stone cleaning mechanism is also included, which includes a rotating rod 6, a plurality of plow blades 61, and a plurality of steel wires 62. The rotating rod 6 is arranged above the crossbeam 1, and the plow blades 61 are welded at equal distances along the length of the rotating rod 6. The plurality of steel wires 62 are arranged at equal distances, and the ends of the steel wires 62 pass through the plow blades 61.

[0047] The connecting block 3 is provided with a through slot 31 , the lower end of the connecting block 3 is welded to the crossbeam stem, a motor-driven roller 32 is pivotally connected to the bottom of the inner wall of the slot 31 , and the rotating rod 6 passes through the slot 31 and contacts the roller 32 .

[0048] The two outermost plow blades 61 are fixedly installed with tension sensing units on their sides, and the ends of the steel wires 62 are fixedly installed with the working ends of the tension sensing units. The steel wires 62 are in a just-tensioned state. The plow blades 61 are in front of the only transverse tube of the mulch film, and the lower ends of the plow blades 61 just touch the soil surface and do not extend into the soil. The tension sensing unit is electrically connected to the control module of the rice transplanter.

[0049] Working principle: If there are gravel particles on the soil surface during the movement, the gravel particles touch the steel wire 62. After the steel wire 62 is hit by the gravel particles, the steel wire 62 pulls the tension sensing unit, and the tension sensing unit feeds back the information to the control module. When the measured force exceeds the preset value, the gravel particles on the surface are large. At this time, the roller 32 drives the rotating rod 6 to rotate, causing the rotating rod 6 to rotate 45°, so that the plow blade 61 tilts upward, thereby throwing the gravel particles forward. Then the roller 32 rotates in the opposite direction to reset the plow blade 61. This is repeated continuously to clean up the gravel particles on the soil surface and prevent the ground film from being scratched by the sharp parts of the gravel particles during the laying process.

[0050] The connecting part 1 can be composed of a base 5, a middle gear 51, a roller 52 and a positioning block 4. The side of the base 5 is pivoted to the rotating rod 6, the middle gear 51 is pivoted under the base 5, the end of the crossbeam 1 is welded to the axial end of the middle gear 51, and a tooth groove is opened on the surface of the roller 52. The middle gear 51 is meshed with the tooth groove of the roller 52. A belt 53 is connected between the middle gear 51 and the roller 52. The center of the roller 52 is fixedly installed with the positioning block 4, and the right end of the positioning block 4 is connected to the left end of the ground film horizontal tube.

[0051] The rod of the positioning block 4 is penetrated by a connecting rod 41, which is in an arc shape. The left end of the positioning block 4 is slidably matched with a slider 42, and the right end of the positioning block 4 is provided with a slide groove, in which the slider 42 is slidably matched. The left end of the mulch horizontal pipe is provided with an interface adapted to the slider 42.

[0052] The connecting rod 41 is cut with an opening by a single ring, as shown in the attached Figure 5As shown, when not in use, the opening faces the right end of the positioning block 4. When in use, align the left end of the mulch horizontal pipe with the positioning block 4, insert one end of the slider 42 into the interface, and then push the connecting rod 41 so that the connecting rod 41 can penetrate through the mulch horizontal pipe and the slider 42. This achieves the purpose of fixation.

[0053] A vertically-shaped sliding cavity 43 is provided in the positioning block 4. Ball bearings 44 are placed on the inner wall of the sliding cavity 43, and a pressure sensing unit 45 is fixedly installed at one end of the inner wall of the ball bearings 44. A single-chip microcomputer and a battery are also fixedly installed in the positioning block 4. Since this is a conventional technical means, no detailed description will be given. The pressure sensing unit 45 is electrically connected to the single-chip microcomputer and the battery. Each time the mulch horizontal pipe rotates one week, the ball bearings 44 strike the pressure sensing unit 45 once, thereby playing a role in counting and being able to inform the operator of the rice transplanter of the mulch usage in real time.

[0054] The positioning member can be composed of a sliding seat 8, a motor 81, a rotating seat 82, and a second screw rod 83. The top of the sliding seat 8 is fixedly installed with the motor 81 and the rotating seat 82. The rotating seat 82 is located directly below the motor 81. The transmission shaft of the motor 81 is welded to the right end of the cross beam rod 1. The right end of the positioning block 4 is pivotally connected to the sliding seat 8. The right end of the mulch horizontal pipe enters the rotating seat 82, and the second screw rod 83 threadedly penetrates through the mulch horizontal pipe and the rotating seat 82.

[0055] It also includes a slide rail 9, which is symmetrically arranged on both sides of the cross beam rod 1. The rollers 52 and the sliding seat 8 are both placed in the slide rail 9. This enables the rice transplanter to travel straight forward and avoids the travel path of the rice transplanter shifting during travel, resulting in the mulch not being able to move straight forward and affecting the mulch laying effect.

[0056] Docking grooves 91 are provided at the front and rear ends of the slide rail 9, and loop buckles 92 are welded to the side ends of the slide rail 9. Multiple slide rails 9 are spliced together through the docking grooves 91. The docking grooves 91 of two adjacent slide rails 9 are mutually attached, and a plug 93 is inserted.

[0057] It also includes a lapping bar 7, and one end of the lapping bar 7 is pivotally connected to the right end of the mulch horizontal pipe. The lapping bar 7 naturally hangs down and contacts the soil surface, so that the mulch can be just in good contact with the soil surface.

[0058] After the mulch is laid, the edge will be affected by the wind, resulting in the mulch edge warping. In severe cases, the mulch will be blown up or blown crooked. Therefore, Embodiment 3 is set up to solve this problem, as Figures 11-13 shown:

[0059] It also includes two soil compaction and covering mechanisms 10 which are located on both sides of the plastic film. The soil compaction and covering mechanism 10 includes a base plate 101, a toothed ring 102, a pinion gear 103 driven by a motor, an extension part 104 and a J-shaped plate 105. The end of the horizontal pipe of the plastic film penetrates through the base plate 101. A bracket is welded to the bottom of the rice transplanter, and the bracket is threadedly fixed to the base plate 101 through bolts and nuts.

[0060] The toothed ring 102 is pivotally connected to the base plate 101, and the toothed ring 102 and the base plate 101 are arranged concentrically. A motor is fixedly embedded on the side of the base plate 101, and the transmission shaft of the motor is welded to the pinion gear 103. The pinion gear 103 meshes with the toothed ring 102, and the front side of the toothed ring 102 is connected to the extension part 104, and the toothed ring 102 and the extension part 104 are integrally formed.

[0061] The extension part 104 extends forward to the edge of the plastic film and is fixedly installed with the J-shaped plate 105.

[0062] A bent part 1051 is connected to the lower end of the J-shaped plate 105, and the J-shaped plate 105 and the bent part 1051 are integrally formed. A leakage hole 1052 is formed at the bottom of the J-shaped plate 105, and the J-shaped plate 105 is aligned with the edge of the plastic film. The J-shaped plate 105 is also longitudinally provided with a plurality of screw holes, and the screw holes are used to finely adjust the fixed position of the J-shaped plate 105, so as to change the depth of the J-shaped plate 105 pressed into the soil.

[0063] Before work, the extension part is flush with the ground and in a horizontal state, and the J-shaped plate 105 does not contact the plastic film. Working principle: Timely control the pinion gear 103 to rotate forward, so that the toothed ring 102 deflects downward by 60°. The J-shaped plate 105 descends to press the ground edge into the soil. During the pressing process, since the bent part 1051 is inclined, the soil at the edge of the plastic film is squeezed and loosened and slides into the J-shaped plate 105. Then the pinion gear 103 rotates reversely, so that the J-shaped plate 105 resets. During the lifting process, the soil inside the J-shaped plate 105 falls out from the leakage hole 1052, thus covering the edge of the plastic film.

[0064] Even if no soil slides into the J-shaped plate 105, but since the ground edge has been pressed into the soil and a groove is formed on the soil surface, as long as soil is manually scattered into the groove later, the edge of the plastic film can still be buried.

[0065] To sum up, the plastic film installation mechanism for rice transplanting is composed of a cross beam rod 1, a sleeve 11, an iron block 12 and a ferrule 13, and is installed at the bottom of the rice transplanter. An annular groove is formed inside the ferrule 13. Through the cooperation of the fixing ring 2 and the first screw 21, the air ring 23 is connected to the right end of the horizontal pipe of the plastic film, and the air ring 23 is embedded into the groove of the ferrule 13, so as to achieve the fixing effect. The overall structure is simple, and the installation and disassembly are more convenient, further reducing the maintenance cost. It replaces the traditional manual laying, improves the work efficiency and reduces the labor intensity of farmers.

[0066] Moreover, a stone cleaning mechanism is also provided. The stone cleaning mechanism includes a rotating rod 6, a plow blade 61 and a steel wire 62. Tensile induction units are connected to the two outermost plow blades 61. A blocking net is formed by the plow blades 6 and the steel wire 62. Whether there are stone particles on the soil surface is judged according to whether the tensile induction units are subjected to tensile force. Then, through the cooperation of the connecting block 3 and the roller 32, the rotating rod 6 is driven to rotate to drive the blocking net to tilt up, so as to throw the stone particles forward and make the stone particles away from the plastic film. This can avoid the plastic film being scratched by the stone particles. Thus, the protective effect is achieved.

[0067] Moreover, a compaction and soil covering mechanism 10 is also provided. The compaction and soil covering mechanism 10 is composed of a base plate 101, a toothed ring 102, a small gear 103 driven by a motor, an extension part 104 and a J-shaped plate 105. The J-shaped plate 105 is used to press the edge of the plastic film into the soil. In this process, the soil at the edge of the plastic film is prone to loosen, collapse and slide into the J-shaped plate 105. Then the J-shaped plate 105 is lifted, and the sliding soil falls out from the leakage holes 1052, so as to achieve the purpose of covering the edge of the plastic film with soil. This can avoid the plastic film being blown crooked or blown up after being laid. Ensure the compaction rate of the plastic film edge.
