Description

TECHNICAL FIELD

[0002] In the vegetable planting industry, the efficiency and quality of the whole process operation from soil pretreatment to seed sowing directly determine the growth cycle, yield and quality of the vegetables. At present, the vegetable planting mode in China presents the characteristics of "mainly by scattered farmers and gradually popularized by large-scale planting".

[0003] For the current ploughing and seeding device, the disclosed integrated ploughing and seeding device for vegetable planting of patent No. CN109937634B rotates the screw rod as a whole around the balance sleeve, drives the rotating drum to rotate from both ends of the rotating drum, places the vegetable seeds in the interior of the rotating drum in advance, the rotating drum is communicated with the seeding hole, the vegetable seeds fall onto the ground through the seeding hole, the setting of the rotating drum avoids the blockage of the vegetable seeds in the interior of the seeding hole, increases the continuity of seeding, and different seeding drum racks provided with different seeding holes can be selected and installed according to different vegetable seed planting requirements. However, in the process of vegetable planting, the device is directly used to scatter the seeds on the surface of the ploughed soil. Since there are many varieties of vegetable seeds and the requirements for the seeding depth are different, if the seeds are directly scattered, the vegetable seeds cannot be effectively embedded in the soil, and the seeds remaining on the surface may be blown away by natural wind force, pecked by birds, and even damaged by the equipment during subsequent flattening and irrigation, resulting in a significant decrease in the seed germination rate.

The planter assembly at the front end is started to work first to dig a planting hole with a specified size in the soil, thereby reserving space for subsequent seeding. After the seeds are accurately dropped into the hole dug by the planter assembly at the front end, the planter assembly at the rear end is moved to the area, the shifting plate thereof pushes the loose soil around the hole back into the hole through a reverse or adaptive rotating track, thereby completing the automatic filling work of the hole after seeding and avoiding exposure of the seeds to external interference.

[0030] In the embodiment, first, the device is connected with the external traction device through the mounting block 3, after the connection is completed, the vegetable seeds are put into the seed storage box 9, and the movable cover plate is closed.

[0031] Then, the driving machine 34 is started to drive the rotating rod 35 to rotate, the plow wheel 36 fixedly arranged at intervals on the rotating rod 35 rotates in the arc-shaped baffle 33, (at the same time, according to the hardness of the soil and the requirement of the plowing depth, the extension length of the hydraulic rod 31 at the bottom end of the mounting block 3 is adjusted, the hydraulic rod 31 drives the arc-shaped baffle 33 and the plow wheel 36 to move up and down through the support rod 32, and the plowing depth of the plow wheel 36 is changed), the rotating plow wheel 36 cuts and loosens the soil, and the arc-shaped baffle 33 can prevent the soil from splashing during the plowing process, thereby realizing the plowing treatment of the soil in the operation area.

[0032] In the process of plowing, the electric push rod 4 on both sides of the machine base 1 drives the U-shaped frame 5 to slide downward along the fixed block 6, thereby driving the bottom horizontal plate 7 and the first and second push plates 76 and 710 to adjust to the required depth of the vegetable seeds. After the adjustment is completed, the electric telescopic rod 71 in the front horizontal plate 7 is started to push the multiple rack gears 72 to move forward. Since the electric telescopic rod 71 and the multiple rack gears 72 are arranged in an upper and lower and opposite manner, the moving directions of the two multiple rack gears 72 are opposite. In the process of moving the multiple rack gears 72, the first and second gears 74 and 78 are engaged. The first and second gears 74 and 78 rotate under force. In the process of rotating the first gear 74, the first rotating column 73 is rotated synchronously. In the process of rotating the second gear 78, the second rotating column 77 rotates in the first rotating column 73. In the process of rotating the first and second rotating columns 73 and 77, the first and second connecting rods 75 and 79 rotate along the central axis points of the rotating columns, thereby driving the bottom first and second push plates 76 and 710 to push the soil apart to form a pit. The seeds are put into the pit through the conveying assembly and the discharging assembly, and then the pit is filled and leveled by the pit digging assembly in the rear horizontal plate 7, so as to avoid the exposure of the seeds.

[0033] In the process of digging the pit, the drip irrigation assembly is driven to operate, thereby watering the seeds after sowing. With the continuous movement of the traction equipment, the flattening roller 13 compacts the soil after sowing. Embodiment Two

[0034] With reference to Figures 4-7 The embodiment further has the following further content: the drip irrigation assembly is used for drip irrigation of the seeds after sowing. The drip irrigation assembly comprises a lead screw 81, a sliding block 82, a support rod 83, a rectangular plate 84, a piston rod 85, a sealing pipe 86, a water outlet pipe 87, a drip head 88, a water inlet pipe 89, and a water storage tank 810. The lead screw 81 is rotationally connected to the inner wall of the sleeve rod 8. The lead screw 81 is fixedly connected to the second rotating column 77. The sliding block 82 is threadedly connected to the reciprocating lead screw 81. The support rod 83 is fixedly connected to the top surface of the sliding block 82 in a symmetrical manner. The support rod 83 is slidably connected to the sleeve rod 8. The rectangular plate 84 is fixedly connected to one end of the support rod 83 away from the sliding block 82. The piston rod 85 is fixedly connected to one end of the rectangular plate 84 away from the support rod 83. The sealing pipe 86 is sealingly sleeved on the piston rod 85. The water outlet pipe 87 is communicated to the top end of the sealing pipe 86. The drip head 88 is communicated to one end of the water outlet pipe 87 away from the sealing pipe 86. The water inlet pipe 89 is communicated to the sealing pipe 86. The water storage tank 810 is fixedly connected to the side wall of the seed storage tank 9. The water storage tank 810 is communicated with the water inlet pipe 89. Electromagnetic valves are arranged in the water inlet pipe 89 and the water outlet pipe 87. A plurality of sealing pipes 86 are connected through the water inlet pipe 89 and controlled by the electromagnetic valves to control the water into the sealing pipes 86 and the water outlet pipes 87.

[0035] In this embodiment, when the second rotating column 77 rotates, the screw rod 81 rotates synchronously. When the second rotating column 77 rotates forward, the screw rod 81 drives the sliding block 82 in the outer threaded sleeve to slide upward in the sleeve rod 8, thereby pushing the piston rod 85 to push the stored water in the sealed pipe 86 into the water outlet pipe 87, and then into the pit through the drip head 88. When the second rotating column 77 rotates reversely, the screw rod 81 drives the sliding block 82 to slide downward, thereby driving the piston rod 85 to move downward. When the piston rod 85 moves downward, negative pressure is generated, and the water in the water storage tank 810 is pumped into the sealed pipe 86 through the water inlet pipe 89 for storage.

[0036] When the rear side ditching assembly operates, the drip irrigation assembly also operates synchronously, thereby moisturizing the filled pit surface soil and ensuring that the seeds have sufficient water. Embodiment Three

[0037] With reference to Figures 8-9 Compared with Embodiment One and Embodiment Two, in this embodiment, the conveying assembly is used to convey the seeds in the seed storage tank 9 to the discharge cylinder 10. The conveying assembly comprises a servo motor 91, a rotating shaft 92, a protective cover 93, a first bevel gear 94, a rotating rod 95, a second bevel gear 96, and a spiral blade 97. The servo motor 91 is fixedly connected to the side wall of the seed storage tank 9. The rotating shaft 92 is fixedly connected to the output end of the servo motor 91. The rotating shaft 92 is rotatably connected to the inner wall of the seed storage tank 9. The protective cover 93 is rotatably sleeved on the rotating shaft 92. The first bevel gear 94 is fixedly connected to the rotating shaft 92. The rotating rod 95 is rotatably connected to the inner wall of the discharge cylinder 10. The rotating rod 95 is rotatably connected to the protective cover 93. The rotating rod 95 is arranged to rotate in the seed storage tank 9. The second bevel gear 96 is fixedly connected to the rotating rod 95. The first bevel gear 94 and the second bevel gear 96 are meshed with each other. The spiral blade 97 is fixedly connected to the rotating rod 95. The spiral blade 97 is arranged to rotate in the seed storage tank 9 and the discharge cylinder 10. The poking assembly is used to poke the seeds on the rotating disc 11. The poking assembly comprises a convex disc 101, a convex block 102, a poking rod 103, and a discharge hole 104. The convex disc 101 is fixedly connected to the inner wall of the discharge cylinder 10. The convex block 102 is fixedly connected to the rotating rod 95. The poking rod 103 is annularly and equidistantly arranged at the bottom end of the convex block 102. The discharge hole 104 is equidistantly formed in the convex disc 101.

[0038] In this embodiment, when the seeds are conveyed, the servo motor 91 is started, and the output end thereof drives the rotating shaft 92 fixedly connected thereto to rotate synchronously. The rotating shaft 92 is rotatably connected to the inner wall of the seed storage tank 9 through a bearing. Meanwhile, the protective cover 93 rotatably sleeved on the rotating shaft 92 can effectively isolate the seeds in the seed storage tank 9 from the rotating shaft 92 and the subsequent transmission components, thereby avoiding that the seeds are involved in the gap between the components and affecting the transmission accuracy.

[0039] When the rotating shaft 92 rotates, the first bevel gear 94 fixed outside it meshes with the first bevel gear 94. Since the bevel gear transmission can realize the vertical direction of motion, the horizontal rotation of the rotating shaft 92 is converted into the vertical rotation of the rotating rod 95. The external spiral blade 97 also rotates. The rotating spiral blade 97 will generate an axial thrust on the seeds in the seed storage box 9, and gradually push the seeds along the spiral trajectory of the spiral blade 97 to the connection between the seed storage box 9 and the feeding cylinder 10. After entering the feeding cylinder 10, the spiral blade 97 continues to rotate, and smoothly conveys the seeds to the cam 101.

[0040] When the rotating rod 95 rotates, the externally fixed protrusion 102 rotates accordingly, and drives the multiple bottom levers 103 to rotate, pushing the seeds on the convex plate 101 into the feeding pipe 112 through the feeding hole 104, thereby avoiding a large number of vegetable seeds being pushed onto the convex plate 101, which would cause blockage of the feeding hole 104. Example 4:

[0041] like Figures 9-11 As shown, in this embodiment, the seeding assembly is used to intermittently release seeds into the soil. The seeding assembly includes an inclined wheel 111, a feeding pipe 112, a through groove 113, a hollow rod 114, a moving rod 115, a spring 116, a wedge block 117, a first baffle 118, a second baffle 119, and a through hole 120. The inclined wheel 111 is fixedly connected to the rotating rod 95. The feeding pipe 112 is located at the bottom of the convex plate 101 and communicates with the feeding hole 104. The through groove 113 is staggered downwards on the feeding pipe 112. The hollow rod 114 is fixedly connected to the lower... The side wall of the material cylinder 10 is connected to the inner wall of the hollow rod 114 via a sliding rod 115. One end of the spring 116 is fixedly connected to the inner wall of the hollow rod 114, and the other end of the spring 116 is fixedly connected to the bottom end of the sliding rod 115. A wedge block 117 is fixedly connected to the end of the sliding rod 115 away from the hollow rod 114. A first baffle 118 is fixedly connected to the sliding rod 115, and a second baffle 119 is fixedly connected to the sliding rod 115. The first baffle 118 and the second baffle 119 are slidably connected to the through groove 113. Through holes 120 are equally spaced on the rotating disk 11.

[0042] In this embodiment, when the rotating rod 95 of the conveying component rotates, it will synchronously drive the inclined wheel 111 fixedly sleeved on its outside and the rotating disk 11 rotatably connected to the inner wall of the feeding cylinder 10 to rotate synchronously.

[0043] When the inclined wheel 111 rotates with the rotating rod 95, the convex part of the inclined wheel 111 will periodically contact the wedge block 117 at the end of the moving rod 115: in the contact stage, the convex end of the inclined wheel 111 exerts a lateral extrusion force on the wedge block 117, pushing the wedge block 117 to move towards the hollow rod 114, thereby driving the moving rod 115 to slide backward along the inner wall of the hollow rod 114, at this time the spring 116 in the hollow rod 114 is compressed, storing elastic potential energy, when the moving rod 115 slides backward, the first baffle 118 fixed on the surface of the moving rod 115 synchronously moves backward out of the through slot 113 of the feeding pipe 112, while the second baffle 119 moves forward and enters the through slot 113, at this time the first baffle 118 unblocks the feeding pipe 112, and the seeds can fall from the feeding pipe 112 onto the second baffle 119 and cannot continue to fall, thereby completing the temporary storage of the seeds. With the continuous rotation of the inclined wheel 111, the convex part of the inclined wheel 111 is separated from the wedge block 117, the elastic potential energy stored in the spring 116 is released, pushing the moving rod 115 to slide forward along the inner wall of the hollow rod 114 to reset, and the wedge block 117 also returns to the initial position. During the resetting process of the moving rod 115, the first baffle 118 is moved forward into the through slot 113, and vice versa, the second baffle 119 is moved backward out of the through slot 113, at this time the second baffle 119 unblocks the feeding pipe 112, and the first baffle 118 re-blocks the feeding pipe 112 to prevent new seeds from entering, while the seeds temporarily stored on the second baffle 119 fall into the through hole 120 of the rotating disc 11 below. The rotating disc 11 continues to rotate with the rotating rod 95, driving the through hole 120 carrying the seeds to rotate synchronously along the inner wall of the feeding cylinder 10, when the through hole 120 rotates to coincide with the feeding circular hole 12 at the bottom of the feeding cylinder 10, the seeds in the through hole 120 fall under the action of gravity and fall into the pre-dug soil pit, effectively avoiding the problem of over-falling and missing sowing caused by the one-time over-falling of the seeds.
