Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an automated transplanting device for green onion planting, specifically a manually assisted automatic seedling-raising green onion transplanting machine, which can realize the integrated operations of seedling-raising, transmission, transplanting, trenching, soil covering and pipe laying. Background Art

[0002] Green onion is a common and widely used vegetable with a vast planting area and a huge consumer group around the world. Its main production areas, such as Zhangqiu, Shandong, Baodi, Tianjin, Yutian, Hebei, and Linquan, Anhui, have basically formed regional large-scale planting and management. As the world's main producer of green onions, my country's green onion industry carries economic value and social significance that cannot be ignored. However, relying on the traditional manual transplanting of green onion seedlings is inefficient and costly. Today, with the continuous acceleration of agricultural modernization, the research and development of professional machinery suitable for green onion seedling transplanting is imminent. Efficient transplanting machinery can not only greatly shorten the planting cycle and improve the survival rate of green onion seedlings, but also save manpower expenses for green onion farmers, freeing up more labor to engage in other agricultural production links. Therefore, it is urgent to study green onion seedling transplanting machinery.

[0003] Among the onion seedling transplanters currently being studied at home and abroad, the transplanters can be divided into clamp type, hanging basket type, flexible disc type, seedling guide tube type and conveyor belt type according to the form of the transplanter, and most of the transplanting machinery is already quite mature, but the seedling placement work in most transplanters is done manually, which is labor-intensive and costly.

[0004] The flexible disc-type onion seedling transplanter has high working efficiency, low cost and is more practical. However, in the flexible disc-type onion seedling transplanters currently available at home and abroad, the seedling placement work cannot be automated or semi-automated, and the onion seedlings are still placed manually. my country currently lacks a practical onion seedling transplanter with lower labor costs and higher working efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a manual-assisted automatic seedling-planting green onion transplanter and a use method thereof, so as to automate the seedling-planting process, thereby improving work efficiency and reducing labor costs.

[0006] The present invention is realized through the following technical scheme: a manually assisted automatic seedling transplanting machine for green onions, comprising a frame provided with a belt and a seedling planting device, including an onion seedling bucket arranged on the frame and located directly above the belt, a seedling roller located at the opening of the onion seedling bucket and driving the onion seedlings to move onto the belt, and a vibration mechanism driving the onion seedling bucket to vibrate. The frame is also provided with a transmission structure connected to the belt drive shaft and synchronously driving the seedling roller, the vibration mechanism, and the flexure disk to move. When in use, the present invention realizes automation of the seedling placing process. Compared with the original flexible disc type onion seedling transplanter, an onion seedling bucket and a seedling placing roller are newly added. The seedling placing roller rotates to drive the onion seedlings in the onion seedling bucket to fall into the belt. The onion seedlings are dispersed and slide into the seedling placing roller under the operation of the vibration mechanism. While improving work efficiency, the labor cost is reduced and the onion seedling loss rate is reduced. At the same time, through the setting of the transmission structure, the synchronous starting and operation of the seedling placing roller, the vibration mechanism and the flexible disc are realized.

[0007] Preferably, a plurality of teeth evenly arranged along the circumferential direction are fixedly connected to the circumferential surface of the seedling upper roller, and a seedling pulling groove for a single onion seedling to enter is formed between two adjacent teeth.

[0008] This preferred solution facilitates the implementation of pushing the onion seedlings onto the belt one by one through the provision of the pushing teeth, thereby avoiding the onion seedlings from being transported in clusters, that is, ensuring that too many onion seedlings are not squeezed in one seedling pushing groove at the same time during transportation, thereby reducing the onion seedling loss caused by the small space during the transmission of the onion seedlings to the transplanting device.

[0009] Preferably, a plurality of seedling partitioning boards arranged along the conveying direction are provided on the conveying surface of the belt, a seedling placing groove is formed between two adjacent seedling partitioning boards, the seedling placing groove is adapted to the size of the seedling removing groove, the belts are arranged in pairs, the seedling partitioning boards on the two relatively arranged belts are arranged at intervals, and a gap is formed between the vertical sections of the two belts and the seedling partitioning boards to limit the spacing space of the onion seedlings.

[0010] When this preferred solution is in use, the onion seedling loss rate during the seedling placement process is reduced by matching the size of the seedling placement groove and the seedling removal groove. At the same time, at the two vertical sections of the belts, the two belts and the corresponding seedling separation plates cooperate with each other to form a spacing space, thereby eliminating the need for the setting of a vertical conveyor belt. Both belts can transmit the onion seedlings, thereby speeding up the onion seedling transplanting efficiency.

[0011] Preferably, the vibration mechanism includes a crankshaft axially connected to a bracket and located at the lower end of the onion seedling bucket, a crank arranged on the crankshaft, and a connecting rod shaft diameter axially connected between two adjacent cranks, a vibration rod is fixedly connected to the connecting rod shaft diameter, the vibration rod is hinged on a support, the top surface of the support is connected to the lower end surface of the onion seedling bucket through a spring, and a guide cylinder for inserting the spring is provided on the support and the onion seedling bucket.

[0012] When the preferred solution is in use, the crankshaft rotates to drive the crank and the connecting rod shaft diameter to rotate. The connecting rod shaft diameter rotates to compress the spring back and forth through the vibrating rod, thereby realizing the vibration of the onion seedling bucket.

[0013] Preferably, the transmission structure comprises a first bevel gear coaxially arranged with the first pulley of the belt, a seventh cylindrical gear driving the flexure disk to work, and a gear set connecting the first bevel gear and the seventh cylindrical gear; The transmission structure also includes an eighth cylindrical gear coaxially arranged with the second pulley of the belt, a ninth cylindrical gear coaxially arranged with the upper seedling roller and meshing with the eighth cylindrical gear, and a vibrating cylindrical gear coaxially arranged with the crankshaft and meshing with the eighth cylindrical gear.

[0014] This preferred solution realizes the linkage between the belt and the flexure disk through the first bevel gear, the gear set, and the seventh cylindrical gear, realizes the linkage between the belt and the seedling upper roller through the eighth cylindrical gear and the ninth cylindrical gear, and realizes the linkage between the belt and the seedling upper roller through the eighth cylindrical gear and the ninth cylindrical gear, thereby realizing the linkage between the belt, the vibration mechanism, the seedling upper roller, and the flexure disk.

[0015] Preferably, the reducer on the frame drives the second bevel gear to rotate.

[0016] This preferred solution realizes the linkage of the belt, the vibration mechanism, the seedling loading roller and the flexure disk by the speed reducer, thereby reducing the subsequent maintenance cost of using an additional motor and the manufacturing cost of the overall machinery.

[0017] Preferably, the inner bottom surface of the onion seedling bucket is an inclined surface inclined toward the upward seedling roller, and one end of the inclined surface away from the onion seedling bucket is located above the other end.

[0018] This preferred solution provides a guiding effect on the onion seedlings by setting the inclined surface.

[0019] Preferably, the frame is also provided with a pipe-laying device located behind the seat, and the pipe-laying device includes a pipe-laying rotating wheel with a water pipe wrapped around it, and a pressure wheel in contact with the ground. After the water pipe bypasses the pressure wheel, it is laid into the ditch by the pressure wheel.

[0020] When the preferred solution is in use, water pipes can be laid at the same time when transplanting green onion seedlings, thereby facilitating the laying of water pipes.

[0021] Preferably, four belts are provided, and the arrangement of four belts can meet the requirement of simultaneous transplanting of two rows of onion seedlings.

[0022] A method for using a manual-assisted automatic seedling-raising green onion transplanter comprises the following steps: a. Put the prepared onion seedlings into the onion seedling bucket. Under the action of the vibration mechanism, the onion seedlings are dispersed and slide down the onion seedling bucket to the intersection of the onion seedling bucket opening and the upper seedling roller teeth. The upper seedling roller rotates, and the onion seedlings are caught between the teeth and brought to the belt. The onion seedlings between the teeth of the upper seedling roller will fall into the belt when the upper seedling roller rolls. b. The onion seedlings that fall into the belt are slowly transported to the gap between the symmetry lines of the two belts under the transmission of the belt, that is, to the vertical section of the belt, where the partitions on the two belts are cross-distributed to prevent multiple onion seedlings from falling at one time and reduce the loss rate of onion seedlings due to squeezing during the transmission process; c. The onion seedlings clamped by the rotating flexure disk are driven to a position with their roots facing downwards through the rotation of the flexure disk. The roots are aligned with the grooves opened in advance by the furrow opener. The pressing mechanism clamps the roots of the onion seedlings, removes them from the flexure disk, and moves them into the groove. The covering mechanism gathers the soil to cover the roots of the onion seedlings that have just been transferred to the soil, making the transplanting of the onion seedlings more stable. The beneficial effects of the present invention are: (1) The seedling placement process is automated. Compared with the original flexible disc-type onion seedling transplanter, an onion seedling bucket and a seedling placement roller are newly added. The seedling placement roller rotates through gear transmission, driving the onion seedlings in the onion seedling bucket to fall into the belt. A vibration mechanism that works through gear transmission is installed under the onion seedling bucket. The onion seedlings slide into the seedling placement roller in a dispersed manner under the vibration mechanism, thereby improving work efficiency and reducing the onion seedling loss rate.

[0023] (2) By setting up the transmission structure, the onion seedling transplanter relies on the tractor output shaft to output power, and at the same time drives the belt, vibration mechanism, seedling roller, and deflection plate to move, thereby reducing the manufacturing and subsequent maintenance costs.

[0024] (3) The addition of a pipe-laying device makes it possible to simultaneously complete trenching, soil covering, transplanting, and pipe-laying tasks, thereby improving work efficiency and reducing labor costs.

[0025] (4) The transmission structure of the onion seedling transplanter adopts a gear group gear transmission method, which has a more stable transmission ratio and higher transmission efficiency, reduces the size of the transplanting machinery, and improves work flexibility and work efficiency.

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0028] Refer to the attached Figure 1-3 The present invention is as follows Figure 1 As shown, a manually assisted automatic seedling transplanter for green onions and a method of using the same are provided in the present invention.

The seedling planting device is a prior art.

[0029] The transmission device 2 includes a belt, which is transmitted in a right-angled triangle. The frame is provided with a first pulley, a second pulley and a third rotating shaft of the transmission belt. The two belts form a pair, and the pair of belts is symmetrically arranged. In the pair of belts, the vertical sections of the belts are arranged oppositely.

[0030] The conveying surface of the belt is provided with a plurality of seedling separators arranged along the conveying direction, a seedling placement groove is formed between two adjacent seedling separators, and the plurality of seedling separators form saw teeth on the belt, and the width of the seedling placement groove between the saw teeth of the belt is adapted to the diameter of the onion seedlings. The seedling separators on the two belts arranged opposite to each other are arranged at intervals, and a gap is formed between the vertical sections of the two belts and the seedling separators to limit the spacing space of the onion seedlings.

[0031] The seedling loading device includes an onion seedling bucket located at the upper end of the belt, a seedling loading roller located at the opening of the onion seedling bucket and driving the onion seedlings to move onto the belt, a plurality of shifting teeth evenly arranged along the circumferential direction are fixedly connected to the circumferential surface of the onion seedling loading roller, and a seedling loading groove is formed between two adjacent shifting teeth for a single onion seedling to enter, and an onion seedling box 7 is also provided on the frame below the onion seedling bucket.

[0032] There is a flexure at the lower side of the transmission device. The power output by the tractor output shaft in the three-point suspension device is transmitted through the transmission structure. A sponge is installed in the flexure to protect the onion seedlings.

[0033] There are wheels at 30° to the vertical direction on both sides below the flexure to form a suppression mechanism. A soil covering mechanism is provided behind the suppression mechanism to ensure the stability of the transplanted onion seedlings. A furrow opener is installed in front of the flexure to coincide with the transplanting direction of the onion seedlings.

[0034] like Figure 2-3 As shown, the first pulley is located below the second pulley and the third pulley, and a vertical section of the belt is between the first pulley and the second pulley. The first bevel gear 410 coaxial with the first pulley 201 is meshed with the second bevel gear 411, and the second bevel gear 411 and the first cylindrical gear 401 are both arranged on a driven shaft, which is driven by the power output from the tractor output shaft transmitted by the reducer 502 in the three-point suspension device.

[0035] The first cylindrical gear 401, the second cylindrical gear 402, the third cylindrical gear 403, the fourth cylindrical gear 404, the fifth cylindrical gear 405, the sixth cylindrical gear 406 and the seventh cylindrical gear 407 are meshed in sequence. The seventh cylindrical gear 407 is connected to the flexure disk and drives the flexure disk to rotate. The second cylindrical gear 402, the third cylindrical gear 403, the fourth cylindrical gear 404, the fifth cylindrical gear 405 and the sixth cylindrical gear 406 form a gear set.

[0036] like Figure 4 As shown, the seedling device is arranged corresponding to the belt, that is, a seedling roller 101 and an onion seedling bucket 102 are installed above each belt 204, the tooth shape of the seedling roller 101 is an oblique triangle, the cylindrical gear 409 on the synchronous shaft of the seedling roller 101 is meshed with the cylindrical gear 408 on the synchronous shaft of the second pulley 203, and the opening of the onion seedling bucket 102 is adapted to the teeth of the seedling roller 101, so as to reduce the onion seedling loss rate during the seedling raising process; a three-point suspension device 5 is installed in front of the first pulley 201, and after the tractor output shaft outputs power, it is decelerated in the reducer 502 and outputs power to the transmission structure 4, and the transmission structure 4 transmits power to the first pulley 201 through gear transmission, and the second pulley 203 close to the seedling raising device 1 rotates, and the pulley 203 is driven by the cylindrical gear 408 on the synchronous shaft, so that the seedling roller 101 rotates to complete the seedling raising work.

[0037] like Figure 5As shown, a vibration mechanism 103 is provided at the lower end of the scallion bucket 102, and the vibration mechanism includes a crankshaft axially connected to a bracket and located at the lower end of the scallion bucket, a crank arranged on the crankshaft, and a connecting rod shaft diameter axially connected between two adjacent cranks, the connecting rod shaft diameter is eccentrically arranged, a vibration rod is fixedly connected to the connecting rod shaft diameter, and the vibration rod is hinged on a support, the top surface of the support is connected to the lower end surface of the scallion bucket through a spring, and a guide cylinder for inserting the spring is provided on the support and the scallion bucket.

[0038] The vibrating cylindrical gear 412 set on the same rotating shaft as the crankshaft is meshed with the eighth cylindrical gear 408. The eighth cylindrical gear 408 drives the same crankshaft to rotate through the vibrating cylindrical gear 412. The rotation of the crankshaft drives the crank and the connecting rod shaft to rotate. The rotation of the connecting rod shaft compresses the spring back and forth through the vibrating rod. The onion seedling bucket 102 is rectangular in shape. The onion seedling bucket limits the freedom of the spring, thereby realizing the vibration of the onion seedling bucket. The spring controls the vibration range to ensure that the seedling loading process slides smoothly and dispersedly into the seedling loading roller, thereby reducing labor costs and reducing the onion seedling loss rate.

[0039] like Figure 6 In the transplanting device shown, the furrow opener 304 performs furrowing work, and the center line of its furrowing direction coincides with the center line of the flexure disc 301. A suppression mechanism 302 and a soil covering mechanism 303 are installed behind the flexure disc 301. The suppression mechanism 302 and the soil covering mechanism 303 are both symmetrical structures, and the symmetry axis is parallel to the center line of the flexure disc 301.

[0040] like Figure 7 The pipe-laying device shown in the figure has a pipe-laying wheel 601 installed behind the seat 8 of the frame. When the tractor drags the transplanter forward, the pipe-laying wheel 601 rotates, driving the water pipe to rotate out of the wheel. The wound water pipe bypasses the pipe-laying wheel, adjusts its direction through the pipe-laying wheel 602, and is laid in the groove opened in advance by the front furrow opener 304, completing the pipe-laying work. When the present invention is used, a. Put the prepared onion seedlings into the onion seedling bucket. Under the action of the vibration mechanism, the onion seedlings are dispersed and slide down the onion seedling bucket to the intersection of the onion seedling bucket opening and the upper seedling roller teeth. The upper seedling roller rotates, and the onion seedlings are caught between the teeth and brought to the belt. The onion seedlings between the teeth of the upper seedling roller will fall into the belt when the upper seedling roller rolls. b. The onion seedlings that fall into the belt are slowly transported to the gap between the symmetry lines of the two belts under the transmission of the belt, that is, to the vertical section of the belt, where the partitions on the two belts are cross-distributed to prevent multiple onion seedlings from falling at one time and reduce the loss rate of onion seedlings due to squeezing during the transmission process; c. The onion seedlings clamped by the rotating flexure disk are driven to a position with their roots facing downwards through the rotation of the flexure disk. The roots are aligned with the grooves opened in advance by the furrow opener. The pressing mechanism clamps the roots of the onion seedlings, removes them from the flexure disk, and moves them into the groove. The covering mechanism gathers the soil to cover the roots of the onion seedlings that have just been transferred to the soil, making the transplanting of the onion seedlings more stable.
