Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting equipment, in particular to a hole-digging and watering mechanism for transplanting. Background Art

[0002] During the transplanting period of tobacco field planting, multiple operations are required, including ridge making, fertilization, hole digging, watering, planting seedlings, and re-watering.

[0003] Patent (202122421290.5) discloses a hole-punching and watering mechanism for tobacco transplanting, including a hole-punching mechanism, a watering mechanism and a driving mechanism. By designing a hole-punching structure and a watering mechanism with specific structures and their specific positional relationship, the device can be used for tobacco seedling transplanting operations to achieve synchronous operations of hole-punching and watering. The device can be mounted on a small tractor or any equipment that can move along ridges. The frame moves along the ridges to achieve synchronous and continuous operations of equally spaced hole-punching and watering on the ridges of the tobacco field. Compared with traditional manual hole-punching and watering methods, the efficiency is greatly improved. Compared with existing tobacco seedling transplanters, the structure is simpler and more flexible, and the operation fault tolerance rate is high. Even if there is an error in the hole-punching spacing, accurate watering in the holes can be guaranteed.

[0004] The above patent has found through practice that when the device is inserted into the soil, soil easily enters the first drainage groove and the second drainage groove to cause blockage, so that water cannot effectively enter the hole, resulting in low watering efficiency.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a hole-digging and watering mechanism for transplanting, comprising a support plate, a cylinder is fixedly connected to the right side of the bottom of the support plate, a watering mechanism is arranged inside the cylinder, an annular stabilizing block is fixedly connected to the middle position of the inner wall of the cylinder, a truncated cone is fixedly connected to the bottom of the cylinder, a conical drill is arranged below the cylinder, a driving mechanism is arranged at the top of the support plate, the watering mechanism comprises a water pipe slidably connected to the inner wall of the annular stabilizing block, an annular block is fixedly connected to the bottom of the water pipe, the annular block is slidably connected to the inner wall of the cylinder and the inner wall of the truncated cone, a plurality of water outlets are opened on the circumferential surface of the annular block, the water outlets are connected to the water pipe, the bottom end of the annular block is fixedly connected to the top end of the conical drill, a water inlet pipe is arranged above the support plate, one end of the water inlet pipe passes through the top of the support plate and is connected to the water pipe, and the upper circumferential surface of the water pipe is connected to the driving mechanism.

[0007] Furthermore, the diameter of the cylinder is larger than the maximum diameter of the tapered drill, and the diameters of the upper and lower ends of the frustum are respectively the same as the diameter of the cylinder and the maximum diameter of the tapered drill.

[0008] Furthermore, a sliding groove is formed through the surface of one side of the driving mechanism of the cylinder.

[0009] Furthermore, a rubber ring is provided on the circumferential surface of the annular block at the upper side of the water outlet.

[0010] Furthermore, the driving mechanism includes a cylinder vertically arranged in the middle above the support plate, the bottom end of the cylinder is fixedly connected to a connecting plate, the output end of the cylinder passes through the connecting plate and is fixedly connected to the top of the support plate, the top of the support plate and the left side of the cylinder are vertically fixedly connected with a motor, the output end of the motor passes through the support plate and is fixedly connected to a ball screw, the surface of the ball screw is movably matched and connected to a movable plate, and the end of the movable plate away from the ball screw passes through a slide groove and is fixedly connected to the water pipe.

[0011] Furthermore, a stabilizing plate is longitudinally arranged below the support plate, the bottom end of the ball screw is rotatably connected to the stabilizing plate, guide rods are arranged on both sides of the ball screw, both ends of the guide rods are respectively fixedly connected to the support plate and the stabilizing plate, a stabilizing rod is fixedly connected to the top of the support plate and the front and rear sides of the cylinder, and the surface of the stabilizing rod is slidably connected to the inside of the connecting plate.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] 1. The utility model realizes the hole-making work on the ridge by arranging a cylinder, a truncated cone, a watering mechanism and a conical drill to move downward or upward synchronously. During the hole-making process, the watering mechanism is located inside the cylinder and is not in direct contact with the hole. When the cylinder, the truncated cone, the watering mechanism and the conical drill move to the lowest point, they remain motionless. The conical drill and the watering mechanism inside the cylinder move downward synchronously relative to the cylinder. At this time, the water outlet on the annular block in the watering mechanism moves to the outside of the truncated cone and the conical drill moves away from the cylinder, and then water is discharged from the water outlet. Because there is a certain distance between the conical drill and the truncated cone and the diameter of the annular block is smaller than the diameters of the cylinder and the conical drill, there is a certain space between the water outlet on the annular block and the inner wall of the hole, and the water at the water outlet has a certain water pressure to impact the soil. Therefore, the combination of the two can achieve the situation that the water outlet will not be blocked by the soil when discharging water.

[0014] 2. The utility model sets the diameter of the cylinder to be larger than the maximum diameter of the conical drill. When the cylinder, the frustum, the watering mechanism and the conical drill are synchronously moved out of the hole, water will continue to be discharged from the water outlet. Since the diameter of the cylinder is larger than the maximum diameter of the conical drill, the conical drill will not contact the surrounding soil when moving out of the hole, thereby achieving uniform watering of the entire inner wall of the hole. At the same time, the water poured on the inner wall of the hole can flow into the bottom of the hole from the gap between the conical drill and the surrounding soil and be stored without being carried out of the hole by the equipment, thereby improving the watering efficiency of the equipment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 and Figure 2A hole-digging and watering mechanism for transplanting is shown, and a cylinder 2 is fixedly connected to the right side of the bottom of the support plate 1, a watering mechanism 3 is arranged inside the cylinder 2, an annular stabilizing block 20 is fixedly connected to the middle position of the inner wall of the cylinder 2, a frustum 22 is fixedly connected to the bottom of the cylinder 2, a conical drill 4 is arranged below the cylinder 2, and a driving mechanism 5 is arranged at the top of the support plate 1. The diameter of the cylinder 2 is larger than the maximum diameter of the conical drill 4, and the diameters of the upper and lower ends of the frustum 22 are respectively the same as the diameter of the cylinder 2 and the maximum diameter of the conical drill 4, and a slide groove 21 is opened through the surface of the cylinder 2 on one side of the driving mechanism 5. The setting of the frustum 22 is to allow the connection between the cylinder 2 and the conical drill 4 to pass better when the conical drill 4 breaks the soil, and the design of the annular stabilizing block 20 is for the stability of the water pipe 30 when it slides inside the cylinder 2.

[0023] like Figure 2 and Figure 3 A hole-digging and watering mechanism for transplanting is shown, and the watering mechanism 3 includes a water pipe 30 slidably connected to the inner wall of the annular stabilizing block 20, and an annular block 31 is fixedly connected to the bottom of the water pipe 30. The annular block 31 is slidably connected to the inner wall of the cylinder 2 and the inner wall of the truncated cone 22. A plurality of water outlets 32 are provided on the circumferential surface of the annular block 31, and the water outlets 32 are connected to the water pipe 30. The bottom end of the annular block 31 is fixedly connected to the top of the conical drill 4. A water inlet pipe 34 is arranged above the support plate 1, and one end of the water inlet pipe 34 passes through the top of the support plate 1 and is connected to the water pipe 30. The upper circumferential surface of the water pipe 30 is connected to the driving mechanism 5, and a rubber ring 33 is arranged on the circumferential surface of the annular block 31 on the upper side of the water outlet 32. The design of the rubber ring 33 is to isolate the water from entering the cylinder 2 when the water outlet 32 ​​is discharged, which improves the service life of the equipment. The diameter of the water pipe 30 is smaller than the diameter of the annular block 31.

[0024] In the initial state, the truncated cone 22 at the bottom of the cylinder 2 is in contact with the conical drill 4. When the equipment is running, the driving mechanism 5 pushes the support plate 1 to realize the synchronous downward movement of the cylinder 2, the truncated cone 22, the watering mechanism 3 and the conical drill 4. The moving distance is determined according to the actual situation. The maximum moving distance is less than the distance between the bottom of the chute 21 and the conical drill 4. The conical drill 4 breaks the soil in the front. When the cylinder 2 reaches a certain distance, the driving mechanism 5 stops pushing the support plate 1, so that the cylinder 2 and the truncated cone 2 2 remains stationary, and then the driving mechanism 5 drives the watering mechanism 3 to realize the synchronous downward movement of the watering mechanism 3 and the conical drill 4 relative to the cylindrical body 2. At this time, the water outlet 32 ​​of the annular block 31 in the watering mechanism 3 moves to the outside of the truncated cone 22 and the conical drill 4 is away from the cylindrical body 2. The external water supply equipment inputs water into the water inlet pipe 34, and the water is discharged from the water outlet 32 ​​through the water inlet pipe 34 to realize watering of the bottom of the hole. Because there is a certain distance between the conical drill 4 and the truncated cone 22 and the diameter of the annular block 31 is smaller than The diameters of the cylinder 2 and the conical drill 4 are such that there is a certain space between the water outlet 32 ​​on the annular block 31 and the inner wall of the hole, and the water at the water outlet 32 ​​has a certain water pressure that can impact the soil. The combination of the two ensures that the water outlet 32 ​​will not be blocked when water is discharged. Then the driving mechanism 5 stops driving the watering mechanism 3 and pushes the support plate 1 at the same time, so that the cylinder 2, the truncated table 22, the watering mechanism 3 and the conical drill 4 move upward synchronously until they are moved out of the hole. During the upward movement, water continues to flow out of the water outlet 32. 32 is discharged. Since the diameter of the cylinder 2 is larger than that of the conical drill 4, the conical drill 4 will not contact the surrounding soil when it moves out of the hole, thereby realizing uniform watering of the entire inner wall of the hole. At the same time, the water poured on the inner wall of the hole can flow into the bottom of the hole from the gap between the conical drill 4 and the surrounding soil and be stored without being brought out of the hole by the equipment. After the conical drill 4 moves out of the hole, the driving mechanism 5 then drives the watering mechanism 3 to realize the synchronous upward movement of the watering mechanism 3 and the conical drill 4 relative to the cylinder 2 to restore to the initial state.

[0025] As attached Figure 4The driving mechanism 5 includes a cylinder 55 vertically arranged in the middle above the support plate 1, a connecting plate 56 is fixedly connected to the bottom end of the cylinder 55, an output end of the cylinder 55 passes through the connecting plate 56 and is fixedly connected to the top of the support plate 1, a motor 53 is vertically fixedly connected to the top of the support plate 1 on the left side of the cylinder 55, an output end of the motor 53 passes through the support plate 1 and is fixedly connected to a ball screw 52, ​​a movable plate 54 is movably matched and connected to the surface of the ball screw 52, ​​an end of the movable plate 54 away from the ball screw 52 passes through the slide groove 21 and is fixedly connected to the water pipe 30, and the bottom of the support plate 1 A stabilizing plate 50 is arranged longitudinally, and the bottom end of the ball screw 52 is rotatably connected to the stabilizing plate 50. Guide rods 51 are arranged on both sides of the ball screw 52. The two ends of the guide rods 51 are respectively fixedly connected to the support plate 1 and the stabilizing plate 50. The top of the support plate 1 is fixedly connected to a stabilizing rod 57 on the front and rear sides of the cylinder 55. The surface of the stabilizing rod 57 is slidably connected to the inside of the connecting plate 56. The connecting plate 56 and the cylinder 55 are fixedly connected to the frame of an external device (such as a small tractor or any equipment that can move along the ridge). The function of the stabilizing rod 57 is to ensure stability when the cylinder 55 pushes the support plate 1 to move back and forth up and down.

[0026] When the equipment is running, the cylinder 55 drives the support plate 1 to realize the synchronous up and down reciprocating motion of the motor 53, the cylinder 2, the watering mechanism 3 and the conical drill 4. When it moves downward to a certain distance, the cylinder 55 stops working and the motor 53 starts. The motor 53 drives the movable plate 54 to reciprocate up and down through the ball screw 52. The movable plate 54 drives the watering mechanism 3 to move, thereby realizing the synchronous up and down reciprocating motion of the watering mechanism 3 and the conical drill 4 relative to the cylinder 2. After that, the motor 53 stops working and the cylinder 55 drives the support plate 1 to realize the upward movement of the motor 53, the cylinder 2, the watering mechanism 3 and the conical drill 4 to move out of the cave. After moving out of the cave, the cylinder 55 stops working and the motor 53 works to restore the watering mechanism 3 and the conical drill 4 to their initial state.

[0027] The working principle of the utility model is as follows: in the initial state, the truncated platform 22 at the bottom of the cylinder 2 is in contact with the conical drill 4. When the equipment is running, the cylinder 55 in the driving mechanism 5 pushes the support plate 1 to realize the synchronous downward movement of the cylinder 2, the truncated platform 22, the watering mechanism 3 and the conical drill 4. The moving distance is determined according to the actual situation. The maximum moving distance is less than the distance between the chute 21 and the conical drill 4. The conical drill 4 breaks the soil in the front. When the cylinder 2 reaches a certain distance, the driving mechanism 5 stops pushing the support plate 1 to keep the cylinder 2 and the truncated platform 22 in the same position. The watering mechanism 3 is held stationary, and then the motor 53 in the driving mechanism 5 pushes the watering mechanism 3 to move downward through the connecting plate 56, so that the watering mechanism 3 and the conical drill 4 move downward synchronously relative to the cylindrical body 2. At this time, the water outlet 32 ​​of the annular block 31 in the watering mechanism 3 moves to the outside of the truncated cone 22 and the conical drill 4 is away from the cylindrical body 2. The external water delivery equipment inputs water into the water inlet pipe 34, and the water is discharged from the water outlet 32 ​​through the water inlet pipe 34, so as to realize watering the bottom of the hole. Because there is a certain distance between the conical drill 4 and the truncated cone 22 and the diameter of the annular block 31 is smaller than that of the cylindrical body 2 and the maximum diameter of the conical drill 4, so there is a certain space between the water outlet 32 ​​on the annular block 31 and the inner wall of the hole, and the water at the water outlet 32 ​​has a certain water pressure to impact the soil, and the combination of the two can achieve that the water outlet 32 ​​will not be blocked when the water is discharged, and then the motor 53 stops working, and the cylinder 55 in the driving mechanism 5 pushes the support plate 1 to achieve the synchronous upward movement of the cylinder 2, the frustum 22, the watering mechanism 3 and the conical drill 4 to move out of the hole. In the process of moving upward, water is continuously discharged from the water outlet 32. Because the diameter of the cylinder 2 is large, The diameter of the conical drill 4 is such that the conical drill 4 will not come into contact with the surrounding soil when it is moved out of the hole, thereby achieving uniform watering of the entire inner wall of the hole. At the same time, the water poured on the inner wall of the hole can flow into the bottom of the hole from the gap between the conical drill 4 and the surrounding soil and be stored without being carried out of the hole by the equipment. When the conical drill 4 is moved out of the hole, the motor 53 in the driving mechanism 5 then drives the watering mechanism 3, so that the watering mechanism 3 and the conical drill 4 move upward synchronously relative to the cylinder 2 to restore to the initial state, thereby achieving watering of the hole during the hole-making process.

Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
