Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tobacco planting, and particularly relates to a hole digging and seedling throwing equipment for tobacco-crop combined planting mode on a ridge. BACKGROUND

[0002] Tobacco is planted on a ridge, and in order to ensure that the root system of the tobacco plant has sufficient development and nutrient absorption space, the distance between the tobacco ridges is designed to be large, which causes the idle of the part of the farmland. Meanwhile, the field growth period of the tobacco plant is from March to October, and the remaining time of the tobacco field is also in the idle period, so the tobacco-crop combined planting mode is proposed on this basis, that is, after the tobacco is harvested, the tobacco field is plowed and exposed to the sun, and then the ridge is formed in advance, and crops such as winter wheat are planted between the ridges. At the transplanting period at the end of March of the next year, the tobacco ridge is punched and the seedling is transplanted, so that the farmland can be fully utilized and the grain yield can be effectively guaranteed. However, the following problems occur in actual application: 1) the tobacco ridge is formed early, and after being idle for several months, the ridge is prone to collapse and the height is reduced, which cannot meet the requirements of the tobacco seedling transplanting in the later period; 2) the tobacco seedling transplanting period is just the wheat emergence period, and the distance between the tobacco ridge side and the wheat is very small, so it is difficult to meet the moving operation space of the existing hole digging and automatic seedling throwing equipment, and therefore manual hole digging and manual seedling throwing are mostly used, which is not only low in efficiency but also time-consuming and labor-intensive. SUMMARY

[0003] In view of the deficiencies of the prior art, the purpose of the present application is to provide a hole digging and seedling throwing equipment for tobacco-crop combined planting mode on a ridge, which has a simple overall structure and can effectively design the distance between the grain and the seedling to meet the hole digging and seedling throwing synchronous operation in the tobacco-crop combined planting mode.

[0012] Preferably, the covering member comprises a fixed frame corresponding to the seedling cup and fixedly arranged on the bottom surface of the seedling tray, a bent rod rotatably arranged on the bottom of the fixed frame, and a baffle connected to the top of the bent rod and used for covering the bottom end of the seedling cup.

[0013] Preferably, the top surface of the baffle is wedge-shaped with a low point facing the rotating direction of the seedling tray.

[0014] Preferably, a reset spring is further arranged between the fixed frame and the bent rod, the reset spring is in a non-deformation state, and the baffle covers the bottom end of the seedling cup.

[0015] Preferably, the bottom surface of the baffle is further provided with a pushing block at one end away from the bent rod.

[0016] The opening member comprises a mounting frame fixedly arranged on the platform, a pushing rod arranged on the top of the mounting frame, and a free end of the pushing rod located on the movement path of the pushing block.

[0017] Preferably, the hole digging rod of the hole digging mechanism is arranged at the middle line of the platform width, and a spiral auger is fixedly connected to the bottom of the hole digging rod in a coaxial manner, and the bottom of the spiral auger is sharp.

[0018] Preferably, the hole digging mechanism further comprises a limiting rod slidingly matched with a pre-set through hole of the sliding block, and the bottom of the limiting rod is fixedly arranged on the platform.

[0019] Preferably, a protrusion is arranged on the wheel surface of the moving wheel, the wheel shafts of the two moving wheels are matched with the bearings pre-set on the bottom of the supporting plate, and the top of the supporting plate is fixedly arranged on the bottom surface of the platform.

[0020] Preferably, the driving gear and the hole digging gear are in a state of not simultaneously meshing with the toothed belt section at all times.

[0021] The seedling tray gear and the driving gear are always in a state of non-simultaneous meshing with the belt tooth belt section.

[0022] Preferably, one end of the platform towards the advancing direction is a widening part with increasing width, and the other end is a ridge protection part;

[0023] The ridge protection part is provided with a ridge protection plate extending downward on both sides, and the two ridge protection plates are arranged in an inclined manner with the bottom part away from each other.

[0024] The widening part is provided with a widening plate extending downward on both sides, and the two widening plates are arranged in an inclined manner with the bottom part close to each other, the bottom surface of the widening plate is arranged at an angle with the horizontal surface, and the end away from the advancing direction of the platform is connected to the bottom surface of the ridge protection plate and is higher than the bottom surface of the widening plate towards the end of the advancing direction of the platform.

[0025] The working process of the present application is as follows:

[0026] First, the two moving wheels are placed across the two sides of the tobacco ridge, then the driving motor is started, the driving motor drives the corresponding belt pulley to rotate, and then the belt rotates. The tooth belt section of the belt moves to the driving gear first and realizes meshing with the driving gear, so that the driving gear rotates. The driving gear drives the driving shaft and the driving bevel gear to rotate and realizes the rotation of the driven bevel gear and the axle, thereby realizing the one-way movement of the rolling wheel driving the entire platform. At the same time, during the movement of the whole machine, the front end of the widening plate is cut into the soil below, and during the movement, the self-inclined folding structure makes the soil continuously gathered and finally gathered and extruded by the subsequent ridge protection plate to form a shape, thereby increasing the height of the tobacco ridge to meet the needs of tobacco seedling growth.

[0027] When the tooth belt section moves away from the driving gear, the driving gear stops moving with the whole machine. At this moment, the auger reaches the transplanting and hole digging position. As the tooth belt section continues to move to the hole digging gear and realizes meshing with the hole digging gear, the hole digging gear rotates, the hole digging gear drives the reciprocating screw to rotate and realizes the downward movement of the sliding block, thereby driving the hole digging motor and the auger to move downward to contact the ridge soil and then enter the soil. At the same time, the auger driven by the hole digging motor rotates to dig a tobacco hole in the ridge soil. As the reciprocating screw continues to rotate, the sliding block can be reset upward, thereby moving the auger out of the tobacco hole. When the tooth belt section moves away from the hole digging gear, the sliding block completes a vertical reciprocating movement, thereby realizing the hole digging and resetting operation of the auger. During the whole process, the sliding block is limited by the limiting rod and will not swing, ensuring the accuracy of the hole digging position.

[0028] When the tooth belt segment moves to the position where it is engaged with the seedling tray gear, the seedling tray gear drives the seedling tray and the seedling cup to rotate. When the seedling cup moves to the position close to the push rod, the blocking piece is limited by the push rod and cannot continue to rotate synchronously with the seedling cup. The fixed frame continues to rotate, which causes the blocking piece to displace relative to the seedling cup and the reset spring to deform. As the displacement of the blocking piece relative to the seedling tray changes, the blocking piece gradually disengages from the limit of the push rod in the displacement. When the seedling cup continuously rotates to the position above the seedling dropping pipe, the blocking piece loses the effective covering effect on the bottom of the seedling cup, and the tobacco seedlings in the seedling cup fall into the seedling dropping pipe and finally slide into the tobacco hole, completing the seedling planting in the current tobacco hole. As the seedling tray and the seedling cup continue to rotate until the tooth belt segment moves away from the seedling tray gear, the seedling tray no longer rotates, and the blocking piece moves out of the limit range of the push rod and resets under the action of the reset spring to effectively cover the bottom of the corresponding seedling cup. Due to the wedge surface on the top surface of the blocking piece, the tobacco seedlings can slide along the wedge surface as much as possible, which not only ensures the effective falling of the tobacco seedlings, but also prevents the tobacco seedlings from being dragged by the blocking piece and being squeezed by the inner wall of the seedling cup when the blocking piece moves.

[0029] When the tooth belt segment continues to move to the driving gear and is engaged with the driving gear, the whole machine is driven to move again, and the above operation is repeated until the seedling planting of all the seedling cups is completed. The tobacco seedlings are small in size, so the number of seedling cups can be designed to be larger to meet the requirement that one seedling tray can complete the seedling planting of one tobacco ridge. Of course, the tobacco farmer needs to supplement the seedling cups at the end of the tobacco ridge, and then the present application can be used for the hole digging and seedling planting of the next tobacco ridge.

[0030] It should be noted that the driving motor can be equipped with a speed reducer to meet the low-speed and high-power operation of the belt. At the same time, the transmission ratios of the gears and the tooth belt segment are different, which should meet the requirement that the angular velocity of the seedling tray gear is the smallest. The specific design parameters are designed according to the sizes of the seedling tray, the moving wheel, etc., which are not described here. Moreover, in order to save space, the tooth belt segment can simultaneously engage and drive the hole digging gear and the seedling tray gear, but it needs to meet the requirement that the tobacco seedlings are separated from the seedling cup when the tooth belt segment is separated from the hole digging gear.

[0031] Compared with the prior art, the present application has the following advantages: the overall structure of the present application is simple and can effectively design the distance between the tobacco seedlings, which meets the requirements of hole digging and seedling planting in the tobacco and grain integrated planting mode.

[0044] A pushing rod 510 is horizontally arranged below the seedling tray 52, the free end of the pushing rod 510 is located on the moving path of the pushing block 58 and intermittently contacts the baffle pushing block 58 corresponding to each seedling cup, and the other end of the pushing rod 510 is connected with a mounting frame 59 fixedly arranged on the platform 1;

[0045] A seedling falling pipe 6 is further penetratingly arranged on the platform 1 at one side of the mounting frame 59, the top of the seedling falling pipe 6 is arranged directly below the moving track of the seedling cup 53, the bottom of the seedling falling pipe 6 is inclined and arranged beside the bottom end of the spiral auger 47;

[0046] The toothed belt section 21 of the belt 2 is sequentially engaged with the driving gear 31, the hole digging gear 41 and the seedling tray gear 51, and the driving gear 31 and the hole digging gear 41 are not simultaneously engaged with the toothed belt section 21 at all times; the seedling tray gear 51 and the driving gear 31 are not simultaneously engaged with the toothed belt section 21 at all times.

[0047] The working process of the application is as follows:

[0048] Firstly, the two moving wheels 36 are moved across the two sides of the tobacco ridge, and then the driving motor 23 is started to drive the corresponding belt pulley 22 to rotate, thereby realizing the rotation of the belt 2. The toothed belt section 21 of the belt is first moved to the driving gear 31 and is engaged with the driving gear 31, so that the driving gear 31 rotates. The driving gear 31 drives the driving shaft 32 and the driving bevel gear 33 to rotate and drive the driven bevel gear 34 and the wheel shaft 35 to rotate, thereby realizing the one-way movement of the rolling wheel 36 and the entire platform 1. At the same time, during the movement of the entire machine, the front end of the expander plate 13 is cut into the soil below the soil surface, and during the movement, the self-inclined folding structure is used to continuously gather the soil and finally be gathered and extruded into a shape by the subsequent ridge protection plate 14, thereby increasing the height of the tobacco ridge to meet the needs of the growth of tobacco seedlings.

[0049] When the toothed belt section 21 moves away from the driving gear 31, the driving gear 31 and the entire machine stop moving. At this moment, the auger 47 reaches the transplanting and hole digging position. As the toothed belt section 21 continues to move to the hole digging gear 41 and is engaged with the hole digging gear 41, the hole digging gear 41 rotates, the reciprocating screw rod 42 rotates, and the sliding block 43 moves downward, thereby driving the hole digging motor 45 and the auger 47 to move downward to contact the ridge soil and then enter the soil. At the same time, the auger 47 driven by the hole digging motor 45 rotates to dig a tobacco hole in the ridge soil. As the reciprocating screw rod 42 continues to rotate, the sliding block 43 can be reset upward, thereby moving the auger 47 out of the tobacco hole. When the toothed belt section 21 moves away from the hole digging gear 41, the sliding block 43 completes a vertical reciprocating movement, thereby realizing the hole digging and resetting operations of the auger 47. During the entire process, the sliding block 43 is limited by the limiting rod 44 and cannot swing, ensuring the accuracy of the hole digging position.

[0050] When the tooth belt segment 21 moves to the position of the seedling tray gear 51 and achieves meshing with the seedling tray gear 51, the seedling tray gear 51 drives the seedling tray 52 and the seedling cup 53 to rotate, when the seedling cup 53 moves to the position close to the push rod 510, the baffle 57 cannot continue to rotate synchronously with the seedling cup 53 due to the limiting of the push rod 510, and the fixed frame 54 continues to rotate, which causes the displacement of the baffle 57 relative to the seedling cup 53 and the deformation of the reset spring 56, and the displacement of the baffle 57 relative to the seedling tray also causes the baffle 57 to gradually separate from the limiting of the push rod 510 in the displacement, when the seedling cup 53 continuously rotates to the position above the seedling dropping tube 6, the baffle 57 loses the effective covering effect on the bottom of the seedling cup 53, so that the tobacco seedlings in the seedling cup 53 fall into the seedling dropping tube 6 and finally slide into the just punched tobacco hole, completing the seedling dropping of the current tobacco hole. With the continuous rotation of the seedling tray 52 and the seedling cup 53 until the tooth belt segment 21 moves away from the seedling tray gear 51, at this moment the seedling tray 52 no longer rotates, and the baffle 57 also moves out of the limiting range of the push rod 510 and resets under the action of the reset spring 56 to effectively cover the bottom of the corresponding seedling cup 53 again.

[0051] In the above process, due to the wedge surface setting of the top surface of the baffle 57, the tobacco seedlings can slide along the wedge surface as much as possible, which not only can ensure the effective falling of the tobacco seedlings, but also can prevent the phenomenon that the root system of the tobacco seedlings is dragged and damaged by the baffle and the inner wall of the seedling cup due to friction when the baffle 57 moves.

[0052] When the tooth belt segment 21 continues to move to the position of the driving gear 31 and achieves meshing with the driving gear 31, the whole machine is driven to move again, and the above operation is repeated until the seedling dropping of all the seedling cups 53 is completed. The tobacco seedlings are small in size, so the number of the seedling cups 53 can be designed to be larger to meet the requirement that one seedling tray 52 can complete the seedling dropping of one tobacco ridge. Of course, the tobacco farmers also need to supplement the seedlings in the empty seedling cups at the end of the tobacco ridge, so that the present application can be used for the hole punching and seedling dropping of the next tobacco ridge.

[0053] It should be noted that the driving motor 23 can be provided with a speed reducer to meet the low-speed and high-power operation of the belt 1. Meanwhile, the transmission ratios of the gears and the tooth belt segment are different, which should meet the requirement that the angular velocity of the seedling tray gear 51 is the smallest, and the specific design parameters are designed according to the sizes of the seedling tray 52, the moving wheel 36 and the like, which will not be repeated here. Moreover, in order to save space, the tooth belt segment 21 can simultaneously mesh with the hole punching gear 41 and the seedling tray gear 51 for transmission, but it needs to meet the requirement that the tobacco seedlings are separated from the seedling cup 53 when the tooth belt segment 21 is separated from the hole punching gear 41.
