Description

Technical Field

[0001] The invention relates to the technical field of agricultural tools, in particular to a furrowing planter. Background Art

[0002] During the trenching process of the existing trenching planter, the vibration generated by the equipment when it is working will cause the two sides of the trench wall to collapse after the trenching. This phenomenon will affect the trenching depth, resulting in the failure to plant the crops in the ideal soil layer. Therefore, a blocking component with a pressure plate structure is installed on the existing trenching planter to press the soil on both sides of the trench wall to prevent the trench wall from collapsing.

[0003] However, when the existing furrow planter uses the above-mentioned blocking component, if the soil in the planting environment is in a clay state, the blocking component of the pressure plate structure will press the soil on both sides of the furrow wall, and the vibration of the furrow planter will produce top-down pressure on the soil, thereby causing the clay on both sides of the furrow wall to be further compacted. The clay has strong viscosity, and the pores inside the compacted clay are reduced, which leads to a decrease in the air permeability of the soil in the planting environment, thereby causing the problem of soil compaction and reducing the survival rate of seeds.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example: See Figure 1 - Figure 4 As shown, the purpose of this embodiment is to provide a furrowing planter, including a frame 1, a handrail 2 is provided at one end of the frame 1, a moving wheel 3 is rotatably connected to the bottom of the frame 1, a furrowing mechanism 4 is provided at the bottom of the frame 1, a sowing mechanism 5 is provided inside the frame 1, a blocking assembly 11 is provided at the bottom of the frame 1, and a soil breaking mechanism 6 is provided at the bottom of the frame 1. The soil breaking mechanism 6 is arranged on the side of the sowing mechanism 5 away from the furrowing mechanism 4. The soil breaking mechanism 6 is used to break the clay on the side wall of the furrow opened by the furrowing mechanism 4 after the sowing mechanism 5 sows. The soil breaking mechanism 6 includes an angle adjustment assembly 61 and two mounting plates 62, and the two mounting plates 62 are both provided with soil breaking assemblies 63 inside. The angle adjustment assembly 61 is used to adjust the rotation angle of the two mounting plates 62, and the soil breaking assembly 63 is used to crush the clay on the side wall of the groove. When the angle adjustment assembly 61 is started, the two mounting plates 62 rotate to change the contact angle between the soil breaking assembly 63 and the side wall of the groove, thereby adjusting the degree of crushing of the clay on the side wall of the groove by the soil breaking assembly 63.

[0020] The frame 1 is used to install other parts of the device. The handrail 2 can be held by the user to facilitate the user to control the movement of the entire device. The moving wheels 3 are located on both sides of the upper side of the groove when the device is digging grooves. The digging mechanism 4 includes a digging wheel and a driving member. The driving member drives the digging wheel to rotate through a belt transmission assembly to achieve a digging effect. The sowing mechanism 5 includes a seed storage box, a sowing wheel and a sowing pipe. The sowing wheel is used to control a single seed to enter the sowing pipe. After the seed enters the sowing pipe, it falls into the groove opened by the digging mechanism 4. The blocking component 11 is used to smooth the clay on both sides of the groove wall after the digging mechanism 4 digs grooves to prevent the groove wall from collapsing. It is arranged between the digging wheel and the sowing pipe. After the sowing mechanism 5 sends the seeds into the groove, the angle adjustment component 61 drives the two mounting plates 62 to rotate toward the groove walls on both sides, so that the soil breaking component 63 contacts the groove wall. After the soil breaking component 63 breaks a part of the clay on the groove wall, under the weight of the frame 1, the broken groove wall structure is no longer stable, and the clay on both sides of the groove wall collapses to the middle of the groove and buries the seeds. The collapsed clay retains more gaps, which improves the air permeability of the soil at the sowing point, and also effectively avoids the problem of soil compaction.

[0021] In addition, reference Figure 3 - Figure 7The angle adjustment assembly 61 includes a cylinder 611 fixedly connected to the bottom surface of the frame 1 and two rotating shafts 614 rotatably connected to the bottom surface of the frame 1. The telescopic end of the cylinder 611 is fixedly connected to a moving plate 612. Both sides of the moving plate 612 are provided with tooth surfaces. The outsides of the two rotating shafts 614 are fixedly connected to gears 613. The two gears 613 are symmetrically meshed on both sides of the moving plate 612. The bottoms of the two rotating shafts 614 are fixedly connected to the tops of the two mounting plates 62 respectively.

[0022] A No. 1 mounting groove 621 is provided on one side of the mounting plate 62 , and a No. 2 mounting groove 622 is provided on one side of the mounting plate 62 . The No. 2 mounting groove 622 is arranged below the No. 1 mounting groove 621 . A through hole 623 is provided through the bottom surface of the inner wall of the No. 1 mounting groove 621 , and the through hole 623 is connected to the No. 2 mounting groove 622 .

[0023] The earth-breaking assembly 63 includes a motor 631 arranged inside the No. 1 mounting groove 621 and a rotating cylinder 632 rotatably connected inside the No. 2 mounting groove 622. The motor 631 includes an output shaft 6311, which passes through the interior of the through hole 623. The motor 631 is transmission-connected to the rotating cylinder 632 via the output shaft 6311 arranged thereon.

[0024] A plurality of evenly distributed breaking knives 633 are fixedly connected to the outside of the rotating cylinder 632 . One side of the breaking knives 633 is triangular. Two symmetrically distributed breaking rods 634 are fixedly connected to the outside of the breaking knives 633 .

[0025] refer to Fig.10 After the cylinder 611 is started, its telescopic end controls the movement of the moving plate 612, thereby controlling the gear 613 and the rotating shaft 614 to drive the mounting plate 62 to rotate, and then controlling the contact angle between the rotating cylinder 632 and the two sides of the trench wall. The greater the rotation angle of the mounting plate 62, the deeper the soil-breaking knife 633 and the soil-breaking rod 634 enter the trench wall, and the greater the degree of crushing of the clay on both sides of the trench wall. The user can adjust the degree of crushing of the trench wall soil by the soil-breaking component 63 according to the soil conditions of the planting site. If the soil viscosity of the planting site is low, the rotation angle of the mounting plate 62 can be reduced, thereby reducing the depth of the soil-breaking knife 633 and the soil-breaking rod 634 entering the trench wall. Otherwise, the rotation angle of the mounting plate 62 can be increased. When the clay on both sides of the ditch wall is broken, the motor 631 drives the rotating cylinder 632 to rotate through the output shaft 6311, and the triangular surface of the soil-breaking knife 633 enters the clay first. The triangular surface can facilitate the soil-breaking knife 633 to enter the soil, and the soil-breaking rod 634 can further improve the degree of crushing of the clay. During the movement of the frame 1, the rotating cylinder 632 rotates continuously, thereby breaking the clay on both sides of the ditch wall after sowing.

[0026] For further reference, Figure 5 - Figure 8 A protection component 7 is provided on the outside of the motor 631. The protection component 7 is used to protect the motor 631 when the earth-breaking component 63 is working. The protection component 7 includes a fixed frame 71 fixedly connected to the top surface of the inner wall of the No. 1 mounting groove 621. A connecting seat 72 is slidably connected to the top surface of the inner wall of the fixing frame 71. The connecting seat 72 is fixedly connected to the motor 631. A plurality of evenly distributed damping rods 73 are rotatably connected between the connecting seat 72 and the fixing frame 71. The plurality of damping rods 73 are all obliquely arranged inside the fixing frame 71.

[0027] The protection component 7 further includes a bearing member 74 fixedly connected to the outside of the output shaft 6311 . A cushion 75 is fixedly connected to the outside of the bearing member 74 . The cushion 75 is fixedly connected to the inside of the through hole 623 .

[0028] Since the clay on the side wall of the groove may contain gravel after opening, the breaker blade 633 or the breaker rod 634 will be subjected to the reaction of the gravel when it contacts the gravel. This reaction force will be transmitted to the output shaft 6311 through the rotating cylinder 632. After long-term operation, the output shaft 6311 may be broken due to the large reaction force. Therefore, a protection component 7 is provided to protect the output shaft 6311. When the earth-breaking knife 633 or the earth-breaking rod 634 contacts the gravel, the rotating cylinder 632 is subjected to a reaction force from the gravel, and the reaction force is transmitted to the output shaft 6311 and the motor 631 through the rotating cylinder 632. After the motor 631 is subjected to the reaction force, it moves inside the fixed frame 71 through the connecting seat 72. Since the direction of the reaction force is opposite to the rotation direction of the rotating cylinder 632, the motor 631 will rotate axially. At this time, under the action of the obliquely arranged damping rod 73, the reaction force can be effectively buffered. The damping rod 73 is vertically arranged. The obliquely arranged damping rod 73 can allow the motor 631 to rotate axially within a certain angle while buffering the reaction force, thereby more effectively buffering the reaction force. If the damping rod 73 is vertically fixed, the damping rod 73 no longer allows the motor 631 to rotate axially, and the damping rod 73 causes the motor 631 to shift laterally, thereby causing the output shaft 6311 to move laterally inside the through hole 623, which can easily cause the output shaft 6311 to be laterally broken by the through hole 623. In order to avoid lateral rigid collision between the output shaft 6311 and the through hole 623, a soft pad 75 is arranged inside the through hole 623 to buffer and protect the movement of the output shaft 6311. At the same time, in order to enable the output shaft 6311 to rotate smoothly and avoid excessive friction of the soft pad 75 by the output shaft 6311, a bearing member 74 is arranged between the soft pad 75 and the output shaft 6311. The output shaft 6311 can rotate inside the bearing member 74, and the outside of the bearing member 74 can be fixed to the inside of the through hole 623 through the soft pad 75.

[0029] Further, refer to Figure 4 and Fig. 9 A cleaning assembly 8 is provided inside the second mounting groove 622 , and the cleaning assembly 8 is used to clean the clay attached to the outside of the earth-breaking knife 633 and the earth-breaking rod 634 .

[0030] The cleaning assembly 8 includes an air pump 81 fixedly connected to the top of the frame 1 and two mounting frames 82 respectively fixedly connected to the inside of the two No. 2 mounting grooves 622. The air pump 81 includes two air outlet ends. Both air outlet ends of the air pump 81 are provided with air pipes 84. A plurality of evenly distributed jet heads 83 are fixedly connected to the inside of the mounting frame 82, and the air pipes 84 are connected to the jet heads 83.

[0031] The mounting frame 82 is obliquely disposed inside the second mounting groove 622 , the air outlet direction of the air jet head 83 faces the triangular surface of the earth-breaking blade 633 , and the axis of the air outlet direction of the air jet head 83 is tangent to the outside of the rotating cylinder 632 .

[0032] After the soil-breaking component 63 has been working for a period of time, a lot of clay may be attached to the rotating cylinder 632, the soil-breaking knife 633 and the soil-breaking rod 634. The clay will fill the gaps between the three, causing the outer surface of the rotating cylinder 632 to tend to be flat, which will reduce the crushing effect of the soil-breaking component 63 on the clay on the ditch wall. The cleaning component 8 is used to clean the clay attached to the soil-breaking knife 633 and the soil-breaking rod 634, wherein the air pump 81 inputs external gas into the jet head 83 through the air pipe 84. Under the pressurized action of the jet head 83, the jet head 83 sprays airflow on the surface of the soil-breaking knife 633 and the soil-breaking rod 634, thereby crushing and blowing away the attached clay to achieve a cleaning effect. The jet cleaning method can effectively reduce the wear on the surface of the soil-breaking knife 633 and the soil-breaking rod 634 during the cleaning process, and increase the service life of both. refer to Fig.11 The nozzle 83 is set obliquely by the mounting frame 82. Fig.11 Taking the perspective of as an example, after the triangular surface of the earth-breaking knife 633 is separated from the ditch wall, the jet head 83 blows gas to the triangular surface of the earth-breaking knife 633. Since the rotating cylinder 632 rotates clockwise, the relative speed between the earth-breaking knife 633 and the earth-breaking rod 634 and the airflow will be greater than when the jet head 83 is set vertically, thereby improving the cleaning effect. In addition, the jet direction of the jet head 83 is tangent to the outer wall of the rotating cylinder 632, which can ensure effective cleaning of the outer surface of the rotating cylinder 632 while avoiding blowing the airflow directly to the surface of the rotating cylinder 632, thereby reducing the friction between the rotating cylinder 632 and the clay during the cleaning process and increasing the service life of the rotating cylinder 632.

[0033] In summary, the working principle of the device is as follows: first, the user pushes the frame 1 to the designated sowing position through the handrail 2 and the moving wheel 3, and then turns on the driving member inside the furrowing mechanism 4. After the furrowing wheel rotates, the soil is furrowed. Then, the user turns on the sowing wheel to send the seeds into the furrow. The user can push the handrail 2 to move the frame 1 to perform continuous furrowing operations. During this process, the user can turn on the cylinder 611 according to the stickiness of the soil. The cylinder 611 pushes the moving plate 612 to move, and cooperates with the gear 613 to rotate the mounting plate 62. The user turns off the air cylinder 611 to keep the movable plate 612 fixed, and turns on the motor 631 to rotate the rotating cylinder 632. During the rotation of the rotating cylinder 632, the soil-breaking knife 633 and the soil-breaking rod 634 will continuously enter the clay on both sides of the ditch wall, thereby breaking the clay on both sides of the ditch wall. Under the gravity of the frame 1 and the moving wheel 3, the broken ditch wall collapses to bury the sown seeds. There are still gaps between the collapsed clay, which ensures the air permeability of the soil and effectively avoids the problem of soil compaction. In the process of breaking soil by the soil-breaking blade 633 and the soil-breaking rod 634, if the two come into contact with gravel, the motor 631 and the output shaft 6311 will be subjected to the reaction force of the gravel. At this time, the motor 631 moves inside the fixed frame 71 through the connecting seat 72. Since the direction of the reaction force is opposite to the rotation direction of the rotating cylinder 632, the motor 631 will rotate axially. At this time, under the action of the obliquely arranged damping rod 73, the reaction force can be effectively buffered, and the soft pad 75 can protect the output shaft 6311 to prevent it from colliding with the inner wall of the through hole 623 and breaking. After the soil-breaking component 63 has been working for a period of time, a lot of clay may be attached to the rotating cylinder 632, the soil-breaking knife 633 and the soil-breaking rod 634. At this time, the user can turn on the air pump 81, and the air pump 81 inputs the external gas into the nozzle 83 through the air pipe 84. Under the pressurized action of the nozzle 83, the nozzle 83 sprays the air flow onto the surface of the soil-breaking knife 633 and the soil-breaking rod 634, thereby breaking up and blowing away the attached clay, thereby achieving a cleaning effect.
