Description

Technical Field

[0001] The invention relates to the field of citrus planting, in particular to a seedling planting machine for citrus planting. Background Art

[0002] In recent years, with the rapid development of my country's economy and the continuous improvement of people's living standards, people's demand for fruits has become increasingly greater. Citrus is one of the fruits that people eat daily. In the process of planting citrus seedlings, seeds are generally dug in the fields in advance, and people need to manually place the seedlings in the planting pits, and then fill the planting pits with soil to cover the roots of the seedlings. In the process of planting seedlings, people need to bend over constantly, which can easily cause waist fatigue and consume more physical energy, which greatly reduces the speed and efficiency of transplanting.

[0003] According to the published patent 202320226982.0, a seedling placing machine for citrus planting includes a main frame, a soil loosening assembly, a seedling placing assembly, a seedling storage box and a walking assembly. Walking assemblies are arranged on both sides of the main frame, and the walking assembly includes walking wheels. A soil loosening assembly is arranged at the front end of the main frame, and the soil loosening assembly includes a fixed rod, a plow frame and a plow blade. The plow frame is arranged on the main frame, and the plow blade is connected to the plow frame under the fixed rod. The seedling placing assembly is arranged at the rear side of the soil loosening assembly, and the seedling placing assembly includes a lower pressure bottom plate, a telescopic component, a seedling placing plate and a shovel. A seedling storage box is arranged on the lower pressure bottom plate, and a telescopic component is arranged under the seedling placing plate. The utility model can realize soil loosening, drilling and automatic seedling placing, improves the accuracy and efficiency of planting seedlings, and reduces the labor intensity of seedling placing personnel.

[0004] However, in traditional citrus planting operations, the seedling assembly and the soil loosening assembly are independently set, which requires the operator to control these two parts separately, increasing the complexity of the operation, which is not simple and efficient enough. Moreover, since the two components are located at a certain distance from each other, there will be a time difference in actual operation, that is, after the soil is loosened, it takes a while for the seedlings to be implanted in the loosened soil. During this waiting period, the loosened soil pit is prone to collapse due to lack of support, and the soil re-covers the pit, making it difficult for the seedlings to reach the ideal planting depth, thereby affecting the planting quality and survival rate of citrus. At the same time, after the planting operation is completed, many mounds or hillocks formed by loose soil are often left on the surface of the planting pit. For the sake of beauty and convenience of subsequent management, growers often need to spend extra time to use tools to manually level these mounds, which increases labor intensity and operation time. For this reason, it is necessary to design a new technical solution to solve it. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, meet the actual needs, and provide a seedling planting machine for citrus planting to solve the problem that in the current traditional citrus planting operation, the seedling planting component and the soil loosening component are independently arranged, which causes the operator to control these two parts separately, increasing the complexity of the operation, and is not simple and efficient enough. Moreover, since the two components are located a certain distance apart, there will be a time difference in actual operation, that is, after the soil is loosened, it is necessary to wait for a period of time before the seedlings can be implanted in the loosened soil. During this waiting period, the loosened soil pit is prone to collapse due to lack of support, and the soil re-covers the pit, making it difficult for the seedlings to reach the ideal planting depth, thereby affecting the planting quality and survival rate of citrus. At the same time, after the planting operation is completed, many mounds or hillocks formed by the loose soil are often left on the surface of the planting pit. For the sake of beauty and convenience of subsequent management, the grower often needs to spend extra time to use tools to manually level these mounds, which increases the labor intensity and operation time.

[0009] Preferably, a plurality of plow blades are fixed to the outer wall of the arc-shaped shell, and an arc-shaped fixing plate is fixed to the inner wall of the arc-shaped shell. The two arc-shaped fixing plates form a ring, and a rotating tube is sleeved inside the ring. A first fixing bolt passes through the inside of the arc-shaped fixing plate, and the first fixing bolt is threadedly connected to the threaded hole on the surface of the rotating rod.

[0010] Preferably, a mounting plate is fixed to one side of the surface of the arc-shaped shell, a second fixing bolt passes through the interior of the mounting plate, and the second fixing bolt is threadedly connected to the screw hole in the mounting plate, so as to fix the multiple arc-shaped shells.

[0011] Preferably, a box body is installed on one side of the top of the device plate body, a dual-axis motor is installed on one side of the top of the box body, a rotating rod is connected to the bottom of the dual-axis motor, the bottom of the rotating rod extends into the box body, and a plurality of stirring blades are installed on the outside of one end of the rotating rod located in the box body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention combines a driving motor, a rotating tube and a rotating seedling lowering assembly. By using a driving motor to drive multiple plowshares on the outside of the arc-shaped shell to rotate, it can not only efficiently perform soil loosening operations on the ground, but also, because the seedlings are pre-stored in a circular shell composed of two arc-shaped shells, as the arc-shaped shell rotates, the seedlings can be directly thrown out from the seedling lowering openings set on the surface of the arc-shaped shell. These seedling lowering openings are arranged at intervals on the arc-shaped shell, so that the spacing of the seedlings falling can be controlled. By integrating the plowshare and the seedling lowering mechanism into one, it is possible to directly plant the seedlings while loosening the soil, which greatly simplifies the operation process and saves the operator. The cumbersome steps of separately operating different components solve the problem that in traditional citrus planting operations, the seedling planting component and the soil loosening component are independently set, which requires the operator to separately operate these two parts, increasing the complexity of the operation, which is not simple and efficient enough. Moreover, since the two components are located a certain distance apart, there will be a time difference in actual operation, that is, after the soil is loosened, it takes a while to wait for the seedlings to be planted in the loosened soil. During this waiting period, the loosened soil pits are prone to collapse due to lack of support, and the soil re-covers the pits, making it difficult for the seedlings to reach the ideal planting depth, thus affecting the planting quality and survival rate of citrus. Technical problems.

[0018] 2. The present invention utilizes the power output of the dual-axis motor through the combination of a box body, a dual-axis motor and gears, and drives multiple nozzles to perform rotary spraying through the gear transmission principle, thereby expanding the spraying coverage of water and fertilizer. At the same time, the dual-axis motor also synchronously drives multiple stirring blades located in the box body to rotate. These stirring blades effectively promote the uniform mixing of water and fertilizer, and integrate the mixing mechanism with the spraying mechanism. Moreover, a second water pump is arranged outside the box body. The second water pump can pump the mixed water and fertilizer directly into the rotating tube, and then evenly discharge it through the multiple threaded holes densely distributed on the surface of the rotating tube, so that fertilization operations can be carried out simultaneously during soil loosening and seedling planting, thereby greatly improving the overall planting efficiency.

[0019] 3. The present invention combines a telescopic cylinder, a concave plate and a pressure roller. During the process of loosening the soil and planting, the soil piles or hillocks formed on the ground after planting will be directly squeezed and leveled by the pressure roller. In this process, the vibration generated by the vibration motor built into the concave plate will be transmitted to the surface of the pressure roller, which can not only effectively flatten the soil, but also slightly vibrate and loosen the soil, thereby enhancing the air permeability of the soil. In addition, the telescopic cylinder can flexibly adjust the upper and lower positions of the pressure roller to control the pressure applied by the pressure roller to the soil, so that the appropriate downward force can be selected according to different soil types and conditions, thereby improving the adaptability and flexibility of the equipment. Not only that, the vibration generated by the vibration motor will also be transmitted to the plow cutter, so that the plow cutter will produce a vibration effect during the loosening operation, further enhancing the looseness of the soil, optimizing the overall effect of the loosening operation, and solving the problem that after the planting operation is completed, the surface of the planting pit often leaves many soil piles or hillocks formed by loose soil. For the sake of beauty and convenience of subsequent management, planters often need to spend extra time to use tools to manually level these soil piles, which increases labor intensity and operation time.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: A citrus seedling placing machine, see Figures 1 to 4, including a device plate body 1, with walking wheels 101 installed at the front and rear ends of the device plate body 1, a push handle 102 installed on one side of the device plate body 1, and a first arc-shaped support plate 2 and a second arc-shaped support plate 201 are respectively fixed at the front and rear ends of the other side of the device plate body 1, a driving motor 202 is arranged at the front end of the first arc-shaped support plate 2, and a rotating tube 203 is connected to the rear end of the driving motor 202, and the rear end of the rotating tube 203 passes through the first arc-shaped support plate 2 and is rotatably connected to a first rotating joint 308, the first rotating joint 308 passes through the second arc-shaped support plate 201 body, and the penetration position of the first rotating joint 308 and the second arc-shaped support plate 201 body is fixed, a plurality of threaded holes 204 are opened on the surface of the rotating tube 203, and a rotating seedling lowering component is installed on the outside of the rotating tube 203, The device first uses a plurality of arc-shaped shells 205, and the plurality of arc-shaped shells 205 can be paired with each other, and each pair forms a complete circular shell. The arc-shaped fixing plates 207 of the two paired arc-shaped shells 205 are engaged with the surface of the rotating tube 203, and then the arc-shaped shells 205 are firmly fixed on the rotating tube 203 by means of a first fixing bolt 211 through a threaded connection. The outer surfaces of the two arc-shaped shells 205 are both installed with mounting plates 209, and these mounting plates 209 are reinforced with the second fixing bolts 208 running through them to prevent loosening or deformation during operation. After the installation is completed, the operator pushes the device plate 1 and uses the walking device installed at the bottom of the device. The wheel 101 can move the equipment to the designated work site. After arriving at the work site, the drive motor 202 is turned on. After the drive motor 202 is started, the rotating tube 203 is driven to start rotating. The rotating action of the rotating tube 203 will be directly transmitted to the arc-shaped shell 205 fixed thereon. As the rotating tube 203 rotates, the plow blade 210 installed on the surface of the arc-shaped shell 205 starts to contact and cut the soil, thereby achieving soil loosening. At the same time, since the seedlings are pre-stored in a circular shell composed of two arc-shaped shells 205, as the arc-shaped shell 205 continues to rotate, the seedlings are thrown out under the action of centrifugal force and fall into the loosened soil through the lower seedling opening 206 set on the surface of the arc-shaped shell 205. The lower seedling opening 206 is in the arc The spacing arrangement on the shell 205 can control the planting spacing of the seedlings to ensure that each seedling has sufficient growth space, which solves the problem that in traditional citrus planting operations, the seedling lowering component and the soil loosening component are independently arranged, resulting in the operator needing to control these two parts separately, increasing the complexity of the operation, which is not simple and efficient enough. Moreover, since the two components are located a certain distance apart, there will be a time difference in actual operation, that is, after the soil is loosened, it takes a while to wait before the seedlings can be implanted in the loosened soil. During this waiting period, the loosened soil pits are prone to collapse due to lack of support, and the soil re-covers the pits, making it difficult for the seedlings to reach the ideal planting depth, thereby affecting the planting quality and survival rate of citrus.

[0027] For details, see Figure 1 and Figure 2 The rotating seedling lowering assembly includes an arc-shaped shell 205, a seedling lowering opening 206, a coulter 210, an arc-shaped fixing plate 207, a mounting plate 209, a first fixing bolt 211 and a second fixing bolt 208.

[0028] For more details, see Figure 2 The arc-shaped shell 205 is semicircular, and the side of the arc-shaped shell 205 is open, and two semicircular arc-shaped shells 205 form a circular shell.

[0029] For further information, see Figure 2 A plurality of plow blades 210 are fixed to the outer wall of the arc-shaped shell 205, and an arc-shaped fixing plate 207 is fixed to the inner wall of the arc-shaped shell 205. The two arc-shaped fixing plates 207 form a ring, and a rotating tube 203 is sleeved inside the ring. A first fixing bolt 211 passes through the inside of the arc-shaped fixing plate 207, and the first fixing bolt 211 is threadedly connected to the threaded hole 204 on the surface of the rotating rod 312.

[0030] Further, see Figure 2 A mounting plate 209 is fixed to one side of the surface of the arc-shaped shell 205 , and a second fixing bolt 208 penetrates the interior of the mounting plate 209 . The second fixing bolt 208 is threadedly connected to the screw hole in the mounting plate 209 , thereby fixing the multiple arc-shaped shells 205 .

[0031] It is worth noting that see Figure 1 and Figure 3 A box body 3 is installed on one side of the top of the device plate body 1, a dual-axis motor 301 is installed on one side of the top of the box body 3, a rotating rod 312 is connected to the bottom of the dual-axis motor 301, the bottom of the rotating rod 312 extends into the box body 3, and a plurality of stirring blades 313 are installed on the outside of one end of the rotating rod 312 located in the box body 3.

[0032] It is worth noting that see Figure 1 and Figure 3, a first gear 302 is connected to the top of the double-axis motor 301, a second gear 303 is meshed on one side of the first gear 302, a first connecting pipe 304 runs through the inside of the second gear 303, and the penetration position of the first connecting pipe 304 and the second gear 303 is fixed, a plurality of nozzles 305 are connected to the top of the outside of the first connecting pipe 304, and a second rotary joint 314 is connected to the bottom of the first connecting pipe 304 for rotation. When the double-axis motor 301 is started, the bottom output shaft drives the rotating rod 312 to rotate, thereby driving the stirring blades 313 to rotate in the box 3, fully mixing the water and fertilizer to ensure the fertilization effect. At the same time, the top output shaft of the double-axis motor 301 drives the first gear 302 to rotate, drives the second gear 303 and the second rotary joint 314, and then rotates the first connecting pipe 304, and then starts the first water pump 301. The pump 310 draws the mixed water and fertilizer in the box 3 into the first connecting pipe 304 through the third connecting pipe 311 and the second connecting pipe 309. Since the top of the first connecting pipe 304 is sealed, after the water and fertilizer accumulate in the pipe, they are sprayed out in a rotating manner through the nozzle 305, forming a wide-angle spray, increasing the spraying range, and achieving uniform fertilization. While the soil loosening and seedling planting operations are being carried out, the second water pump 306 is started to pump the mixed water and fertilizer into the rotating tube 203. The rotating tube 203 rotates with the soil loosening and the rotation of the planting mechanism, and the threaded holes 204 on its surface evenly discharge water and fertilizer, realizing synchronous fertilization operations, which not only improves the fertilization efficiency, but also ensures that the water and fertilizer can evenly cover the soil and seedlings, thereby promoting crop growth. It should be noted that the surface of the box 3 is provided with an inlet pipe and an outlet pipe (not shown in the figure).

[0033] It is worth mentioning that see Figure 3 The bottom of the second rotary joint 314 is connected to the second connecting pipe 309, the bottom of the second connecting pipe 309 extends into the box body 3 and is connected to the first water pump 310 installed at the top of the inside of the box body 3, and the bottom of the first water pump 310 is connected to the third connecting pipe 311.

[0034] It is worth noting that, see Figure 1 The rear end of the bottom side of the box body 3 is connected to one end of the second water pump 306 , the other end of the second water pump 306 is connected to a hose 307 , and the end of the hose 307 away from the second water pump 306 is connected to a first rotary joint 308 .

[0035] It is worth emphasizing that see Figure 1 and Figure 4A telescopic cylinder 4 is installed on the other side of the top of the device plate body 1. The piston at the bottom of the telescopic cylinder 4 passes through the device plate body 1 and is fixed with a concave plate body 401. Bearings 404 are installed on both sides of the bottom of the concave plate body 401, and a connecting rod 405 is rotatably connected between the two bearings 404. A pressure roller 406 penetrates the outside of the connecting rod 405, and the penetration position of the pressure roller 406 and the connecting rod 405 is fixed. Cavities 402 are opened on both sides of the inside of the concave plate body 401, and a vibration motor 403 is installed inside the cavity 402. After planting is completed, a mound or hillock will be formed on the ground. At this time, the telescopic cylinder 4 adjusts the pressure roller 406 to an appropriate position to ensure that the pressure roller 406 is in contact with the soil. Then the pressure roller 406 starts to roll to squeeze and flatten the soil pile or hillock. The vibration generated by the vibration motor 403 in the concave plate 401 is transmitted to the surface of the pressure roller 406, which not only effectively flattens the soil, but also slightly vibrates and loosens the soil, thereby enhancing the air permeability of the soil. The telescopic cylinder 4 can flexibly adjust the upper and lower positions of the pressure roller 406, thereby controlling the pressure applied to the soil by the pressure roller 406. According to different soil types and conditions, the operator can change the downward pressure by adjusting the telescopic cylinder 4 to ensure that the soil is In order to achieve proper compaction and leveling while avoiding excessive compaction that may lead to damage to the soil structure, the vibration generated by the vibration motor 403 not only acts on the pressure roller 406, but is also transmitted to the plowshare 210. During the loosening operation, the plowshare 210 can cut and loosen the soil more efficiently due to the vibration effect, further improving the overall effect of the loosening operation and solving the problem that after the planting operation is completed, many mounds or hillocks formed by loose soil are often left on the surface of the planting pit. For the sake of aesthetics and subsequent management, growers often need to spend extra time using tools to manually level these mounds, which increases the labor intensity and operation time.

[0036] When using a citrus planting seedling machine, the device first uses a plurality of arc-shaped shells 205. The plurality of arc-shaped shells 205 can be paired with each other. Every two pairs form a complete circular shell. The arc-shaped fixing plates 207 of the two paired arc-shaped shells 205 are engaged with the surface of the rotating tube 203. Then, the arc-shaped shells 205 are firmly fixed to the rotating tube 203 by means of a first fixing bolt 211 through a threaded connection. Mounting plates 209 are installed on the outer surfaces of the two arc-shaped shells 205. These mounting plates 209 are reinforced with the assembly of the two arc-shaped shells 205 by means of a second fixing bolt 208 running through them to prevent loosening or deformation during operation. After the installation is completed, The operator can move the device to the designated work site by pushing the device plate 1 and using the walking wheels 101 installed at the bottom of the device. After arriving at the work site, the driving motor 202 is turned on. After the driving motor 202 is started, the rotating tube 203 is driven to start rotating. The rotating action of the rotating tube 203 will be directly transmitted to the arc-shaped shell 205 fixed thereon. As the rotating tube 203 rotates, the plow blade 210 installed on the surface of the arc-shaped shell 205 starts to contact and cut the soil, thereby achieving soil loosening. At the same time, since the seedlings are pre-stored in the circular shell composed of two arc-shaped shells 205, as the arc-shaped shell 205 continues to rotate, the seedlings are thrown out under the action of centrifugal force, and the seedlings are thrown out by the arc-shaped shell 205. The lower seedling opening 206 on the surface of the arc-shaped shell 205 falls into the loosened soil. The interval arrangement of the lower seedling opening 206 on the arc-shaped shell 205 can control the planting spacing of the seedlings to ensure that each seedling can obtain sufficient growth space. When fertilization is needed, the dual-axis motor 301 is started, and its bottom output shaft drives the rotating rod 312 to rotate, thereby driving the stirring blade 313 to rotate in the box 3, so as to fully mix the water and fertilizer to ensure the fertilization effect. At the same time, the top output shaft of the dual-axis motor 301 drives the first gear 302 to rotate, drives the second gear 303 and the second rotating joint 314, and then rotates the first connecting pipe 304, and then starts the first water pump 310, through the third connecting pipe 311 and the second The connecting pipe 309 draws the mixed water and fertilizer in the box 3 into the first connecting pipe 304. Since the top of the first connecting pipe 304 is sealed, after the water and fertilizer accumulate in the pipe, they are sprayed out in a rotating manner through the nozzle 305, forming a wide-angle spray, increasing the spraying range, and achieving uniform fertilization. While loosening the soil and planting seedlings, the second water pump 306 is started to pump the mixed water and fertilizer into the rotating pipe 203. The rotating pipe 203 rotates with the loosening of the soil and the rotation of the planting mechanism, and the threaded holes 204 on its surface evenly discharge water and fertilizer, realizing synchronous fertilization operations, which not only improves the fertilization efficiency, but also ensures that the water and fertilizer can evenly cover the soil and seedlings, promoting crop growth. After planting, a mound or hillock will form on the ground.At this time, the telescopic cylinder 4 adjusts the pressure roller 406 to an appropriate position to ensure that the pressure roller 406 is in contact with the soil. Then the pressure roller 406 starts to roll to squeeze and flatten the soil pile or hillock. The vibration generated by the vibration motor 403 in the concave plate 401 is transmitted to the surface of the pressure roller 406, which not only effectively flattens the soil, but also slightly vibrates and loosens the soil, thereby enhancing the air permeability of the soil. The telescopic cylinder 4 can flexibly adjust the upper and lower positions of the pressure roller 406, thereby controlling the pressure applied to the soil by the pressure roller 406. According to the soil type and conditions, the operator can change the downward force by adjusting the telescopic cylinder 4 to ensure that the soil is properly compacted and flattened, while avoiding excessive compaction that may cause damage to the soil structure. The vibration generated by the vibration motor 403 not only acts on the pressure roller 406, but is also transmitted to the plowshare 210. During the loosening operation, the plowshare 210 cuts and loosens the soil more efficiently due to the vibration effect, further improving the overall effect of the loosening operation.
