Technical Field

[0001] The utility model relates to the technical field of sowing machinery, in particular to a Chinese herbal medicine root segment sowing device.

[0002] The utility model also relates to a seeder provided with the Chinese herbal medicine root segment sowing device. Background Art

[0003] Traditional Chinese herbal medicines that are propagated by root segments, such as Saposhnikovia divaricata and Salvia miltiorrhiza, are planted manually by flat sowing. This planting method requires manual digging of holes to shallowly bury the root segments, covering the soil and compacting it. This requires hiring a large number of workers for planting, which is costly. In addition, hiring a large number of workers will result in inconsistent spacing and depth of root segments, resulting in missing seedlings.

[0004] To develop Chinese herbal medicine cultivation, it is necessary to scale up the cultivation of Chinese herbal medicine. The large-scale cultivation of Chinese herbal medicine requires sowing machinery and management methods that are suitable for large-scale cultivation. For crops that are propagated by seeds, sowing machines can be used for sowing operations. Existing technologies have realized the automated sowing of seeds. However, for Chinese herbal crops that are propagated by root segments, because the volume of the root segments is much larger than that of the seeds, common sowing machines cannot be used, resulting in difficulty in mechanized sowing of such Chinese herbal crops and low sowing efficiency. Utility Model Content

[0005] In view of this, the utility model aims to provide a Chinese herbal medicine root segment sowing device to improve the sowing efficiency of root segment propagation Chinese herbal medicines.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A Chinese herbal medicine root segment sowing device comprises a furrow opener, a soil cover and a sowing wheel arranged on a mounting frame; the soil cover is connected to the rear end of the furrow opener in the travel direction, and the furrow opener is provided with a sowing channel for the root segments to pass through; the circumferential side wall of the sowing wheel is provided with a conveying blind hole, the diameter of the conveying blind hole gradually increases from the hole bottom to the hole mouth, and is used to contain a single root segment; when the sowing wheel rotates, the root segment can slide out of the conveying blind hole according to its own gravity and fall into the sowing channel.

[0008] Furthermore, the soil cover is pivotally connected to the furrow opener, and a retaining assembly is provided between the soil cover and the furrow opener, and the retaining assembly continuously provides downward pressure to the soil cover.

[0009] Further, the retaining component is configured as a torsion spring.

[0010] Furthermore, a guide inclined plate is provided on the furrow opener at the entrance of the sowing channel, and the guide inclined plate constitutes an outward expansion of the entrance of the sowing channel.

[0012] Furthermore, a transmission assembly is connected between the first soil leveling roller and the seeding wheel, and the transmission assembly constitutes the linkage rotation of the first soil leveling roller and the seeding wheel.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] The seeding wheel described in the utility model is provided with a conveying blind hole, which can accommodate slender rod-shaped root segments. After the furrow opener turns over the soil, as the seeding wheel rotates, the root segments can automatically fall into the seeding channel, and the soil coverer follows closely to cover the soil to complete the seeding, thereby improving the seeding efficiency. When the travel speed of the furrow opener is fixed and the rotation speed of the seeding wheel is fixed, the planting spacing of the Chinese herbal medicine root segment seeding device in the travel direction can be accurately controlled, and the furrowing depth of the furrow opener is relatively fixed, so that each root segment can have a better planting effect.

[0015] Secondly, the holding component continuously presses down the cover, which can keep the cover in contact with the soil. At the same time, the depth of the cover inserted into the soil is relatively fixed, which has a stable covering effect. The holding component is set as a torsion spring, and the torsion force provided by the torsion spring can achieve continuous downward pressure on the cover. A guide ramp is set on the furrow opener, so that even if the root segment does not face the sowing channel when it falls, it can smoothly enter the sowing channel under the guidance of the guide ramp.

[0016] Furthermore, the first soil leveling roller can level the soil before the furrow opener works, so that the depth of the planting furrow turned out by the furrow opener is more stable. The first soil leveling roller will rotate when in contact with the soil, and drive the planting wheel to rotate through the transmission component. By adjusting the transmission ratio of the transmission component, the sowing wheel can rotate through a fixed angle when the Chinese herbal medicine root segment sowing device moves a unit length, thereby realizing the control of the root segment sowing plant spacing.

[0017] Another object of the utility model is to provide a seeder, comprising the above-mentioned Chinese herbal medicine root segment sowing device.

[0020] Furthermore, a second soil-leveling roller that can be raised and lowered is provided at the rear end of the main frame in the traveling direction.

[0021] The seeder described in the utility model can also improve the sowing efficiency by arranging the above-mentioned Chinese herbal medicine root segment sowing device, and can also achieve a better sowing effect.

[0022] Secondly, the rotary tillage device can loosen the soil before trenching, which is conducive to trenching; the ridge-forming device is set up and used in conjunction with the rotary tillage device to form ridges of the soil into trapezoidal ridges, so that drainage ditches can be formed between two adjacent ridges, thereby realizing the drainage function.

[0023] Furthermore, the belt embedding device can embed the drip irrigation belt immediately after the rotary tillage device loosens the soil, without the need for additional embedding of the drip irrigation belt, thereby increasing the functionality of the seeder. The second soil leveling roller can compact the soil surface after covering the soil, thereby improving the sowing effect of the seeder. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Embodiment 1

[0044] The present embodiment relates to a Chinese herbal medicine root segment sowing device 1, which is used to improve the structure of the existing seeder so that it can be adapted to the sowing of root segment propagation Chinese herbal medicines, thereby improving the sowing efficiency of such Chinese herbal medicines.

[0045] In terms of overall structure, the Chinese herbal root sowing device 1 includes a furrow opener 102, a soil cover 103 and a sowing wheel 104 arranged on a mounting frame 101. The soil cover 103 is connected to the rear end of the furrow opener 102 in the direction of travel, and a sowing channel 1021 for the root segment to pass through is provided on the furrow opener 102. The circumferential side wall of the sowing wheel 104 is provided with a conveying blind hole 1041, and the diameter of the conveying blind hole 1041 gradually increases from the bottom to the hole mouth, which is used to hold a single root segment. When the sowing wheel 104 rotates, the root segment can slide out of the conveying blind hole 1041 by its own gravity and fall into the sowing channel 1021.

[0046] As set above, the seeding wheel 104 of this embodiment is provided with a conveying blind hole 1041, which can accommodate slender rod-shaped root segments. After the furrow opener 102 turns over the soil, as the seeding wheel 104 rotates, the root segments can automatically fall into the sowing channel 1021, and the soil cover 103 follows to cover the soil, completing the sowing and improving the sowing efficiency. When the travel speed of the furrow opener 102 is fixed and the rotation speed of the seeding wheel 104 is fixed, the planting spacing of the Chinese herbal medicine root segment sowing device 1 in the travel direction can be accurately controlled, and the furrowing depth of the furrow opener 102 is relatively uniform, which can make each root segment have a better planting effect. The conveying blind hole 1041 is flared, which can facilitate the insertion of the root segment.

[0047] Based on the above overall introduction, specifically, the Chinese herbal medicine root segment sowing device 1 in this embodiment is as follows Figures 1 to 5As shown, the direction of travel of the Chinese herbal root sowing device 1 when working is the front, and the mounting frame 101 is a rectangular frame, including an upper frame 1011 and a lower frame 1012. A first lifting assembly 108 is connected between the upper frame 1011 and the lower frame 1012. In specific implementation, the upper frame 1011 is connected to the mechanical structure carrying the Chinese herbal root sowing device 1, so that the lower frame 1012 can be lifted relative to the upper frame 1011. The furrow opener 102 and the soil cover 103 are both arranged on the lower frame 1012. By changing the height of the lower frame 1012, the furrowing depth of the furrow opener 102 can be adjusted. A furrow opener 102, a soil cover 103 and a sowing wheel 104 form a group, which can sow a row of root segments along the direction of travel of the Chinese herbal root sowing device 1. Multiple groups are arranged on the lower frame 1012 to sow multiple rows of root segments at a time. In this embodiment, five groups are provided.

[0048] The first lifting assembly 108 in this embodiment includes a fixed cylinder 1081, a telescopic column 1082, a screw 1083 and a crank 1084. The fixed cylinder 1081 is fixedly connected to the upper frame 1011 and has an open bottom. The telescopic column 1082 is slidably connected in the fixed cylinder 1081, and the bottom end passes through the fixed cylinder 1081 downward and is fixedly connected to the lower frame 1012. The screw 1083 is rotatably connected in the fixed cylinder 1081 and is threadedly connected to the telescopic column 1082. The top end of the screw 1083 passes through the fixed cylinder 1081 and is fixedly provided with a crank 1084. The first lifting assembly 108 is provided with a group at each of the four corners of the lower frame 1012. In specific implementation, the lifting and leveling of the lower frame 1012 can be achieved by rotating each crank 1084. It is understandable that the first lifting assembly 108 may also adopt telescopic structural elements such as cylinders, electric push rods or hydraulic cylinders, as long as they can achieve the lifting of the lower frame 1012 relative to the upper frame 1011.

[0049] The furrow opener 102 is used to plow out the planting furrow, referring to Figure 2 and Figure 3 The furrow opener 102 of this embodiment is cylindrical, and a sowing channel 1021 is formed inside the furrow opener 102. The front end of the furrow opener 102 is wedge-shaped, and when moving in the surface soil layer, the soil can be turned to both sides to form a planting furrow. The rear end of the furrow opener 102 is connected to the soil cover 103. When performing sowing operations, the furrow opener 102 first plows out the planting furrow, and the root segment falls into the planting furrow from the sowing channel 1021. Finally, the soil cover 103 covers the root segment with soil, and the basic action of the sowing operation can be completed.

[0050] In specific implementation, when the root segment falls from the sowing wheel 104, it may fall outside the range of the sowing channel 1021 due to vibration. In order to solve this problem, a guide inclined plate 1022 is provided at the entrance of the sowing channel 1021 on the furrow opener 102, and the guide inclined plate 1022 constitutes the outer expansion of the entrance of the sowing channel 1021. Specifically, there are four guide inclined plates 1022, which are spliced ​​together to form a hollow quadrangular pyramid-shaped entrance. Even if the root segment does not face the sowing channel 1021 when it falls, it can smoothly enter the sowing channel 1021 through the guidance of the guide inclined plate 1022.

[0051] Based on the need to control the soil thickness of the soil cover 103, the soil cover 103 is pivotally connected to the furrow opener 102, and a retaining assembly 105 is provided between the soil cover 103 and the furrow opener 102, and the retaining assembly 105 continuously provides downward pressure to the soil cover 103. The retaining assembly 105 continuously presses down the soil cover 103, so that the soil cover 103 can maintain contact with the soil, and the depth of the soil cover 103 inserted into the soil is relatively fixed, so that a stable soil covering effect is achieved.

[0052] Specifically, refer to Figure 4 The soil cover 103 is set to be C-shaped with an opening downward, and a pivot 1031 is fixed at the top, and the pivot 1031 is rotatably connected to the furrow opener 102. Backfilling parts 1032 are provided at two opposite ends of the bottom of the soil cover 103, and a backfilling channel with a gradually decreasing cross-section from front to back is formed between the two backfilling parts 1032 for soil to pass through. The soil on both sides of the planting furrow will be pushed into the middle planting furrow by the backfilling parts 1032 to complete the soil covering operation.

[0053] As for the structural setting of the holding assembly 105, it can be designed according to the elastic principle or the magnetic principle, and it is only necessary to ensure that there is a continuous and sufficient downward pressure on the soil cover 103. For example, when the elastic principle is adopted, an elastic member can be set between the soil cover 103 and the furrow opener 102, and the elastic force of the elastic member can be used to maintain the downward pressure on the soil cover 103. For details, refer to Figure 3 The elastic member is configured as a torsion spring, which is sleeved on a pivot 1031 of the soil cover 103, with its two ends respectively abutting against the furrow opener 102 and the soil cover 103. The soil cover 103 can achieve continuous downward pressure on the soil cover 103 by relying on the torsional elastic force provided by the torsion spring.

[0054] In order to make the seeding wheel 104 adaptable to the root segment, refer to Figure 1 and Figure 5, the central axis of the conveying blind hole 1041 does not intersect with the central axis of the seeding wheel 104. In the radially outward direction of the seeding wheel 104, the central axis of the conveying blind hole 1041 is set to be reversely deflected in the rotation direction of the seeding wheel 104, so that the root section can be separated from the seeding wheel 104 at a lower position on the seeding wheel 104, and can fall into the seeding channel 1021 more accurately. Six conveying blind holes 1041 are evenly distributed along the circumference of the seeding wheel 104 of this embodiment. All seeding wheels 104 are coaxially connected to a rotating shaft, and the rotating shaft is rotatably connected to the upper frame 1011. The seeding wheel 104 is also drilled with a mounting hole 1042, and the mounting hole 1042 is connected to a conveying blind hole 1041. When the seeding wheel 104 is specifically installed, after the seeding wheel 104 is sleeved on the rotating shaft, the seeding wheel 104 can be fixed to the rotating shaft by bolts, so that the loading and unloading of the seeding wheel 104 is more convenient and quick.

[0055] As a further optimization of the Chinese herbal medicine root segment sowing device 1, refer to Figure 1 and Figure 2 The Chinese herbal medicine root sowing device 1 also includes a first soil-leveling roller 106 that can be lifted and lowered on the mounting frame 101. The first soil-leveling roller 106 is located in front of the travel direction of the furrow opener 102. A first lifting assembly 108 is provided between the first soil-leveling roller 106 and the upper frame 1011, so that the depth of the first soil-leveling roller 106 pressing down can be adjusted. In specific implementation, the Chinese herbal medicine root sowing device 1 moves, and the first soil-leveling roller 106 rolls against the ground after contacting the ground. During the rolling process, the soil can be leveled, so that the depth of each furrow opener 102 inserted into the soil during the furrowing operation is relatively uniform, and the subsequent root segment planting depth can also be relatively consistent.

[0056] Furthermore, in order to unify the spacing between the root segments after sowing, a transmission assembly 107 is connected between the first soil leveling roller 106 and the seeding wheel 104, and the transmission assembly 107 constitutes the linkage rotation of the first soil leveling roller 106 and the seeding wheel 104. In this embodiment, the transmission assembly 107 is configured as a combination of a sprocket chain, and is provided with a tensioning mechanism 110. When the first soil leveling roller 106 rotates, the seeding wheel 104 rotates synchronously in the same direction, that is, when the first soil leveling roller 106 rolls a certain distance along the surface, the angle of rotation of the seeding wheel 104 is also determined, and the spacing between the root segments planted in the same row can be adjusted by adjusting the transmission ratio of the transmission assembly 107, and the seeding wheel 104 does not need to be provided with an additional power device, which is more energy-saving and environmentally friendly. The tensioning device enables the sprocket and chain to maintain a stable meshing state after the lower frame 1012 and / or the first soil leveling roller 106 are raised or lowered.

[0057] According to the above description of the transmission component 107, it can be understood that the transmission component 107 can also be set to other transmission structures, such as a synchronous belt and synchronous pulley combination, a belt and pulley combination, etc., which, in combination with a tensioning device, can realize the linkage rotation function of the first soil roller 106 and the seeding wheel 104, but the stability of use is poorer than that of the sprocket chain combination.

[0058] In specific implementation, the surface of the first soil leveling roller 106 of this embodiment may adhere to soil after contacting the soil, affecting the subsequent soil leveling operation. Therefore, the first soil leveling roller is equipped with a scraper plate 109. The scraper plate 109 is fixed with two connecting arms 1091, and the two connecting arms 1091 are hinged to the upper frame 1011, so that the scraper plate 109 can be placed on the roller surface of the first soil leveling roller 106 under the action of gravity. When the first soil leveling roller 106 rotates, the scraper plate 109 cleans the roller surface of the first soil leveling roller 106. In this embodiment, the scraper plate 109 is made of angle steel.

The rotary tillage device 3 is arranged on the main frame 2, and is located in front of the Chinese herbal root segment sowing device 1. The ridge forming device 4 includes two forming plates 401 respectively arranged on both sides of the main frame 2, and the top ends of the two forming plates 401 are close to each other, and are used to shape the soil into ridges.

[0062] The rotary tillage device 3 of this embodiment is a common rotary tiller, which can loosen the soil before the furrow opener 102 opens the furrow, reduce the furrowing resistance, and facilitate furrowing. The rotary tillage device 3 is bolted to the front end of the main frame 2 and can be connected to the power machinery that drives the seed drill of this embodiment to move.

[0063] For the specific structure of the molding plate 401, refer to Figure 7In this embodiment, the forming plate 401 is welded to the main frame 2, and the front end is bent to form a soil guide portion 4011. A space wide in front and narrow in the back is formed between the soil guide portions 4011 of the two forming plates 401. The soil loosened by the rotary tillage device 3 will be pushed and formed between the two forming plates 401 after passing through the soil guide portion 4011, forming a trapezoidal ridge. The ridge forming device 4 is provided to cooperate with the rotary tillage device 3, and a drainage ditch can be formed between two adjacent trapezoidal ridges obtained by ridge opening. When heavy rain occurs during the growth of Chinese herbal medicines, drainage can be carried out in time to prevent waterlogging, thereby reducing the diseases and seedling death caused by waterlogging of Chinese herbal medicines.

[0064] In order to improve the functionality of the seeding machine, a belt embedding device 5 is provided between the rotary tillage device 3 and the Chinese herbal root segment seeding device 1, and the belt embedding device 5 is used to embed a drip irrigation belt in the soil. The drip irrigation belt can fully penetrate the soil with less water, making the planting of Chinese herbal medicine more water-saving and environmentally friendly.

[0065] Specifically, refer to Figure 8 and Fig. 9 The buried tape device 5 includes a bracket 501, a reel 502, a buried tape tube 503 and a reel hand wheel 504.

The reel 502 is rotatably arranged on the rotating support 5011 for the drip irrigation tape to be wound. The reel 502 is sleeved with a reel hand wheel 504, and a bolt is threadedly connected on the reel hand wheel 504. Tightening the bolt against the reel 502 can fix the reel hand wheel 504 to the reel 502. Each reel 502 is correspondingly provided with two reel hand wheels 504, and the reel 502 between the two reel hand wheels 504 is the part for the drip irrigation tape to be rolled and stored. The buried tape tube 503 is vertically arranged on the main frame 2, and the bottom end is bent backwards, which is used to guide the drip irrigation tape to be buried in the soil. The top opening of the buried belt pipe 503 is flared to facilitate the introduction of the drip irrigation belt. The front side of the lower part of the buried belt pipe 503 is provided with a wedge-shaped soil-breaking portion 5031, which is used to separate the soil to both sides to reduce the resistance of the buried belt pipe 503 traveling in the soil.

[0066] In specific implementation, the end of the drip irrigation belt is passed through the buried belt tube 503 and buried in the soil. When the planter is moving, the unwinding hand wheel 504 is synchronously rotated to continuously bury the drip irrigation belt in the soil, thereby achieving efficient burial. It should be noted that the buried belt tube 503 and the furrow opener 102 are staggered in the moving direction of the planter to prevent the furrow opener 102 from damaging the previously buried drip irrigation belt. In this embodiment, the buried belt device 5 is provided with three groups.
