Description

Technical Field

[0001] The invention relates to the field of crop seedling planting, and in particular to a well-digging cellar water-injecting seedling-planting machine used in hilly and mountainous areas. Background Art

[0002] Well-pit transplanting refers to digging a well on the ridge during transplanting. The upper part of the well is cylindrical and the lower part is conical. The crop seedlings are then dropped vertically into the well. Since the cone angle of the substrate at the root of the crop seedlings is equal to the cone angle of the lower part of the well, the posture of the crop seedlings always remains vertically upward. Finally, an appropriate amount of water is flushed into the well to allow the substrate to merge with the surrounding soil. This is a new planting technology.

[0003] The current pit-type transplanting method is to carry a pit-making machine on one's back, use a small gasoline engine as the power source, and use a handheld hole-punching device to punch holes. Although this pit-making method meets the requirements of agronomic planting, it has a low degree of automation, high labor intensity, and low work efficiency, and cannot be widely promoted and applied.

[0004] Some hole-digging, water-injecting, seedling-planting and transplanting machines are disclosed in the prior art, but their transmission structures are relatively complicated, resulting in the problems that the hole-digging and forming transplanting machines are large in size, heavy, and not flexible in steering. In addition, when the existing hole-digging and forming transplanting machines are performing the hole-digging operation, the transplanting machines need to stop to dig the holes, which will affect the subsequent seedling planting work and result in low hole-digging efficiency of the transplanting machines. If the transplanting machine is moving forward all the time, the transplanting machine is likely to dig an elliptical hole, which will affect the subsequent seedling planting work. At the same time, the hole-digging head of the hole needs to be continuously moved back and forth rapidly, which will not only cause a large impact on the frame, but also generate relatively large noise.

[0046] For the convenience of description, if the words "up", "down", "left" and "right" appear in the present invention, they only indicate that they are consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0047] Terminology explanation section: The terms "install", "connect", "connect", "fixed" and the like in the present invention should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an internal connection between two elements, or an interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0048] As the background technology introduces, the shortcomings of the prior art, in order to solve the above technical problems, the present invention proposes a well-digging cellar watering and seedling transplanting machine for hilly and mountainous areas. It can realize one-time operation to complete the well-digging cellar, watering, seedling throwing and planting operations. The machine realizes the adjustment of walking speed and planting speed, and the adjustment of planting spacing by switching different gears in the form of gear meshing transmission and chain transmission combination, so as to meet the planting agronomic requirements of different crop seedlings. Through the combination of non-circular gear transmission and multi-rod mechanism, the drill bit moves vertically up and down during the walking process of the machine, and at the same time, under the action of the motor, the drill bit rotates to realize the well-digging function. The upper half of the well is cylindrical, and the lower half is conical, and the cone angle is equal to the cone angle of the shape of the matrix part of the root of the crop seedling. The duckbill planter can be adjusted forward and backward according to the size of the spacing. According to the deviation of the relative ridge, it is adjusted left and right. Under the traction of the multi-rod mechanism, the opening and closing of the duckbill is realized by the connecting rope. The slideway of the crop seedling can be retracted according to the actual situation. The well-pit planting device makes a well-pit on the ridge. During the production process, the water in the water tank is sprayed to the well-pit drill bit through the guide cover under the action of the water pump and the solenoid valve. The water flow moistens the inner wall of the well-pit, improves the adhesion inside the well-pit, avoids the collapse of the hole, and provides suitable temperature and humidity for the growth of crop seedlings. Under the action of the water flow, the matrix part of the root of the crop seedling is integrated with the soil around the well-pit, which is conducive to the survival of the crop seedlings and improves the survival rate.

[0049] After the seedlings enter the seedling throwing device, they fall into the seedling receiving port of the slideway in sequence as the seedling tray rotates, and reach the duckbill planter through the slideway. The planting mechanism sends the seedlings into the well cellar, which greatly improves the planting efficiency of the seedlings and reduces the labor intensity.

One cam of the composite cam is in contact with the second rocker 3-2 through a bearing high pair, and the other cam is in contact with the third connecting rod 3-7 through a bearing high pair; the first output shaft clutch 2-1-9-3 drives the two cams to rotate, and the two cams respectively drive the second rocker and the third connecting rod 3-7 to swing; the third connecting rod 3-7 is connected to the duckbill planter 6 through a connecting rope 6-1 to control the opening and closing of the duckbill planter 6;

[0062] Furthermore, the other ends of the first support rod 3-8-1 and the second support rod 3-8-2 of the well pit forming drill bit support are respectively hinged to the forming drill bit support welding 3-8-6, and one end of the third support rod 3-8-3 is hinged to the third rocker, and the other end is hinged to the forming drill bit support welding 3-8-6, wherein the second support rod 3-8-2 and the third support rod 3-8-3 are fixedly connected by a cylindrical rod, and the cylindrical rod is welded to the connecting handle, and one end of the second connecting rod is hinged to the crank, and the other end is hinged to the connecting handle;

[0063] The specific working process and power transmission process of the above-mentioned well-drilling multi-rod mechanism are as follows:

[0064] When the machine is moving, the clutch 2-1-9-3 and the clutch gear 2-1-9-2 are closed, the sprocket-noncircular gear system 2-2 starts to work, the first output shaft 2-1-9-6 and the third sprocket 2-1-9-1 are key-connected and rotate coaxially, the third sprocket 2-1-9-1 and the fourth sprocket 2-2-1 are driven at the same speed through the chain, the fourth sprocket 2-2-1 and the eighth gear 2-2-2 rotate coaxially, the eighth gear 2-2-2 and the ninth gear 2-2-4 mesh and move, the ninth gear 2-2-4 and the first noncircular gear 2-2-5 rotate coaxially, the first noncircular gear 2-2-5 and the second noncircular gear 2-2-7 mesh and move, the second noncircular gear 2-2-7 and the third output shaft 2-2-8 rotate coaxially. The first rocker 3-1 swings around the first output shaft 2-1-9-6 and plays a supporting role. The second rocker 3-2 swings around a fixed point on the shell surface of the sprocket-noncircular gear system 2-2 and plays a supporting role. The third rocker 3-3 swings around another fixed point on the shell surface of the sprocket-noncircular gear system 2-2 and plays a supporting role. Under the joint action of the first rocker 3-1, the second rocker 3-2, and the third rocker 3-3, the well-drilling multi-rod mechanism 3 plays a supporting role, and each connection point is a movable connection.

[0065] The crank 3-4 rotates a full circle along with the third output shaft 2-2-8, and the crank 3-4 drives the forming drill bit 3-10 of the well-drilling multi-rod mechanism 3 to move up and down through the second connecting rod 3-6. The composite cam 7 rotates a full circle along with the first output shaft 2-1-9-6, and the two cams of the composite cam 7 correct the movement direction of the forming drill bit 3-10 of the well-drilling multi-rod mechanism 3 through the second rocker 3-2 and the third connecting rod 3-7 respectively. Under the action of the first non-circular gear 2-2-5 and the second non-circular gear 2-2-7, the movement direction of the forming drill bit 3-10 is opposite to the forward direction of the machine, and the speed is equal. During the movement of the machine, the forming drill bit 3-10 remains stationary relative to a certain point on the ground. At this time, the forming drill bit 3-10 moves up and down. At the same time, under the action of the micro motor 3-9, the forming drill bit 3-10 rotates, and the water flow control cam 4-1 rotates a full circle with the third output shaft 2-2-8. Through the action of the control rod 4-5, the water injection system 4 regularly implements the water injection operation, and the water flows along the forming drill bit 3-10 to soak the inner wall of the well cellar, completing the well cellar drilling function, and continuing to repeat the next action.

[0066] Furthermore, the molding drill bit 3-10 is connected to the micro motor 3-9, wherein the molding drill bit 3-10 is arranged below the molding drill bit support weld, and the micro motor 3-9 is arranged above the molding drill bit support weld.

[0067] Furthermore, the water injection system is mainly composed of a water tank, a water pump, a water flow control cam 4-1, a solenoid valve 4-2, a deflector 4-3, a bearing 4-4, a control rod 4-5, etc., wherein the water tank is not shown in the figure, the water flow control cam 4-1 is splined with the third output shaft, the water flow control cam 4-1 is in high contact with the bearing 4-4, the bearing 4-3 is connected to a control rod 4-5, the control rod 4-5 controls the solenoid valve 4-2, and then controls the water flow in the water tank through the solenoid valve 4-2; when the water flow control cam 4-1 rotates, the control rod moves with it to realize the switch control of the solenoid valve 4-2; the deflector is fixed below the welded support of the forming drill bit and maintains coaxiality with the forming drill bit, and the water inlet of the deflector is connected to the water tank through a pipeline.

[0068] Furthermore, the seedling planting device 5 is mainly composed of a seedling tray assembly 5-1, a seedling receiving port 5-2, a slide 5-3, a transmission mechanism 5-4, a connecting shaft 5-5, a transmission gear 5-6, and a seedling cup 5-7, wherein the connecting shaft 5-5 is connected to the second output shaft 2-1-9-7 of the gear transmission box; the second output shaft 2-1-9-7 drives the connecting shaft 5-5, the connecting shaft 5-5 is connected to the transmission mechanism 5-4, the transmission mechanism 5-4 drives the seedling tray assembly 5-1 to rotate through the transmission gear 5-6, a circle of seedling cups 5-7 is arranged on the seedling tray assembly 5-1, the upper part of the slide 5-3 is the seedling receiving port 5-2, the slide 5-3 is formed by two slide grooves connected by bolts, and the seedling tray assembly 5-1 is connected to the duckbill planter 6 through the slide 5-3.

[0069] Furthermore, the duckbill planter 6 is connected to the frame by bolts, and is connected to the seedling tray assembly through the slide 5-3 and the seedling receiving port. The duckbill planter 6 includes two symmetrically arranged petals, one of which is connected to the third connecting rod 3-7 by a connecting rope, thereby controlling the opening and closing of the duckbill.

[0070] The above-mentioned parallel-adjustable walking chassis is equipped with a gearbox with a non-circular gear structure, a multi-rod mechanism for digging a well, and a seedling throwing device. As the main key components of the transplanter, the three can realize the adjustment of transplanting speed and plant spacing, well pit making, and the transportation and seedling throwing of crop seedlings, which can improve the working efficiency and replace the traditional operation method of relying on manual carrying of machines and hand-held hole-digging devices, so as to improve the mechanization level and planting scale of tobacco planting. By pushing and pulling the adjustment handle 2-1-8-4, the seventh gear 2-1-8-3 can be switched and meshed with the third gear 2-1-7-2, the fourth gear 2-1-7-3, and the fifth gear 2-1-7-4 respectively, to achieve the adjustment of different plant spacings. At the same time, the planting speed can be adjusted by controlling the size of the machine throttle.

[0071] Through the interaction of the sprocket-noncircular gear system, the well-drilling multi-rod mechanism, and the compound cam, the speed of the well-drilling drill bit during the process of entering and exiting the earth is equal to the speed of the traveling chassis, and the direction is opposite. During the well-drilling process, the well-drilling drill bit maintains a zero speed state in the horizontal direction and forms a well with a uniform diameter in the vertical direction. Then repeat the same action to enter the production of the next well.

[0072] The guide cover is installed on the well cellar forming drill bit, and the water flows out from the guide cover along the well cellar forming drill bit, and the water evenly and quickly wets the inner side of the well cellar to reach the soil moisture of the well cellar forming, ensuring that the well cellar does not collapse. At the same time, the formed well cellar provides suitable temperature and moisture for crop seedlings, improving the survival rate and survival quality of crop seedlings.

[0073] During the pit making process, the duckbill planter is in an open state under the action of the composite cam, and the crop seedlings fall into the pit. By adjusting the position of the duckbill planter relative to the pit forming drill bit and stretching or shortening the length of the seedling drop slide, the requirements of different plant spacing can be met.

[0074] For the crop seedling transplanting mode on the film, on the prepared film-covered tobacco ridge, the wheels on both sides of the transplanter are placed in the ridge furrows, and the well-cellar forming drill is located on the center line of the tobacco ridge. On the one hand, the power of the engine is transmitted to the ground wheel through the chain drive, prompting the machine to move forward, and on the other hand, it drives the well-cellar multi-rod mechanism, seedling throwing device and other components to work through the gear transmission box.

[0075] Under the action of the sprocket-noncircular gear system, the well-cellar forming drill bit realizes intermittent vertical up and down movement into the soil during the forward movement of the transplanter. Under the action of the water injection system, the water flows along the guide cover along the drill bit and the soil, shaping the inner wall of the well cellar. The crop seedlings are manually placed in the seedling cup. As the seedling tray rotates, the crop seedlings fall into the slide regularly, and then slide into the duckbill planter. The duckbill follows the rhythm of the hole-forming drill bit entering the soil, realizing regular seedling drop, and the crop seedlings fall completely into the well cellar that has been made. Under the action of the gear transmission box shifting and speed regulation system, the forward speed and the planting spacing can be switched by operating the adjustment handle.

[0076] During the operation, the monitoring panel installed on the handrail displays in real time the water volume in the water tank, the water output of the deflector, the seedling leakage rate and whether the self-propelled chassis is moving along the ridge in a straight line, as fed back by the intelligent monitoring device. The water output of the deflector and the movement of the self-propelled chassis can be automatically adjusted and can also be adjusted manually.

[0077] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
