Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery sowing, and more specifically, to a furrow opener for agricultural machinery sowing. Background Art

[0002] A furrow opener is a component of agricultural machinery, which is mainly used to open seed furrows or dig seed holes on prepared fields, introduce seeds into the furrows and holes, and then cover them with wet soil. The furrow opener is generally connected to agricultural machinery and equipment, and the agricultural machinery and equipment are used to drive the furrow opener to move, so as to achieve the purpose of furrowing the field.

[0003] After searching, a Chinese patent with authorization announcement number CN217850080U discloses a furrow opener for agricultural machinery sowing. During the movement of the furrowing shovel and the extended shovel, the needle of this structure splits the soil to improve the furrowing efficiency. The width of the entire furrow opener for agricultural machinery sowing is adjusted by rotating the extended shovel, which makes it easier to open furrows of different widths and improves the overall stability of the furrow opener for agricultural machinery sowing.

[0004] However, when this structure is actually used, when adjusting the inclination angle of the two extended shovels, the operator needs to adjust and fix the length of the two manual telescopic rods respectively. During the adjustment process, the widths or inclination angles of the two extended shovels are likely to be inconsistent, and the adjustment steps are cumbersome. When trenching, the trenching is likely to be deformed or irregular due to inconsistent widths or angles, affecting the trenching effect. In view of this, the utility model proposes a trench opener for agricultural machinery sowing. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a furrow opener for agricultural seeding to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a furrow opener for agricultural machinery sowing, comprising a furrowing shovel, the outer end of the furrowing shovel is integrally provided with a sharp end, both ends of the furrowing shovel are hinged with extended shovels, a fixing rod is welded to the rear end of the furrowing shovel, two receiving rods are fixedly installed at the rear end of the fixing rod, a plurality of mounting holes are provided on the surface of the fixing rod, and a plurality of inclined poking pins are welded on the surfaces of the furrowing shovel and the extended shovel.

[0007] It can be seen that in the above structure, the fixing rod can be installed on the agricultural seeding machinery through screws and mounting holes, and then the agricultural seeding machinery is used to drive the trenching shovel and the sharp end to move, so as to achieve the purpose of trenching.

[0008] In order to be able to synchronously adjust the inclination angle of the two extended shovels and improve the ditching effect, preferably, a synchronous adjustment structure is provided between the two extended shovels, and the synchronous adjustment structure includes a mounting frame, the mounting frame is located between the two extended shovels, and the mounting frame is fixedly connected to the two receiving rods, two racks are symmetrically distributed inside the mounting frame, and the two racks are slidably connected inside the mounting frame, a gear is meshed between the two racks, an adjustment block is provided on the surface of the mounting frame, the adjustment block is rotatably connected to the mounting frame, and the adjustment block is fixedly connected to the gear between the two racks, the two racks extend to the outside of the mounting frame, two support seats are fixedly installed on the back of the two extended shovels, a sliding rod is provided between the two support seats, a slider is provided on the outside of the sliding rod, the slider is slidably connected to the outside of the sliding rod, and one end of the rack is hinged to the slider.

[0009] In order to improve the stability of the rack when extending, preferably, both inner walls of the installation frame are provided with guide grooves, and guide blocks are slidably provided inside the guide grooves, and the guide blocks are fixedly installed on the corresponding outer walls of the rack.

[0010] In order to limit the adjustment block and improve the stability of use, preferably, a mounting seat is fixedly provided on the surface of the mounting frame, a threaded rod is installed on the internal thread of the mounting seat, and a plurality of limiting holes are distributed in a ring shape on the surface of the adjustment block, and the threaded rod is adapted to the limiting hole structure.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting a synchronous adjustment structure, the adjustment block is rotated to make the gear rotate between the two racks. The rotation of the gear drives the two racks to extend synchronously in opposite directions, so that the slider hinged to one end of the rack slides and guides outside the slide rod, and then the connection between the two extension shovels and the trenching shovel is hinged and rotated, so as to synchronously adjust the inclination angle between the two extension shovels, ensure that the inclination angles between the two extension shovels are consistent, and the adjustment is convenient, thereby improving the use efficiency;

[0013] 2. By installing the fixing rod on the agricultural seeding machinery, the outer end of the trenching shovel is integrally provided with a sharp end, the trenching shovel and the sharp end are inserted into the soil, and the agricultural seeding machinery drives the trenching shovel and the sharp end to move, so as to achieve the purpose of trenching. Since the outer sides of the extension shovel and the trenching shovel are fixed with poking pins, with the rapid movement of the extension shovel and the trenching shovel, the poking pins split the soil, thereby improving the trenching efficiency;

[0014] 3. When the two racks extend to both sides inside the mounting frame, the guide block slides and guides inside the guide groove, thereby improving the stability of the rack when extending. By rotating the threaded rod, one end of the threaded rod extends to the limiting hole opened by the adjusting block, and the adjusting block is limited and fixed, thereby avoiding the adjusting block from rotating during use, thereby improving the stability of the entire furrow opener operation.

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.

[0024] As attached Figure 1-6The furrow opener for agricultural machinery sowing shown in the figure comprises a furrowing shovel 1, the outer end of which is integrally provided with a sharp end 2, both ends of which are hinged with extension shovels 3, a fixing rod 4 is welded to the rear end of the furrowing shovel 1, two receiving rods 5 are fixedly installed on the rear end of the fixing rod 4, a plurality of mounting holes 13 are provided on the surface of the fixing rod 4, and a plurality of inclined poking pins 14 are welded on the surfaces of the furrowing shovel 1 and the extension shovel 3.

[0025] Specifically, in this structure, the screw passes through the mounting hole 13 on the fixing rod 4 and the agricultural sowing machinery, and the fixing rod 4 is installed on the agricultural sowing machinery. The outer end of the trenching shovel 1 is integrally provided with a sharp end 2. The trenching shovel 1 and the sharp end 2 are inserted into the soil. The agricultural sowing machinery drives the trenching shovel 1 and the sharp end 2 to move to achieve the purpose of trenching. Since the outer sides of the extended shovel 3 and the trenching shovel 1 are fixed with a poking pin 14, as the extended shovel 3 and the trenching shovel 1 move rapidly, the poking pin 14 cuts the soil to improve the trenching efficiency.

[0026] In a specific embodiment, as shown in the attached Figure 2 , 3 As shown in , 4, 6, and 7, a synchronous adjustment structure is provided between the two extension shovels 3, and the synchronous adjustment structure includes a mounting frame 6, the mounting frame 6 is between the two extension shovels 3, and the mounting frame 6 is fixedly connected to the two receiving rods 5, two racks 7 are symmetrically distributed inside the mounting frame 6, and the two racks 7 are slidably connected inside the mounting frame 6, a gear 8 is meshed between the two racks 7, an adjustment block 9 is provided on the surface of the mounting frame 6, the adjustment block 9 is rotatably connected to the mounting frame 6, and the adjustment block 9 is fixedly connected to the gear 8 between the two racks 7, and the two racks 7 extend to the outside of the mounting frame 6;

[0027] Two support seats 10 are fixedly installed on the back of the two extended shovels 3, a slide bar 11 is arranged between the two support seats 10, a slider 12 is arranged outside the slide bar 11, the slider 12 is slidably connected to the outside of the slide bar 11, and one end of the rack 7 is hinged to the slider 12.

[0028] Specifically, in this structure, in order to achieve synchronous adjustment of the inclination angle between the two extended shovels 3, so that the inclination angle between the two extended shovels 3 is consistent, so as to quickly adjust the groove width of the agricultural machinery sowing furrow opener, specifically;

[0029] The operator can rotate the adjustment block 9 so that the adjustment block 9 drives the gear 8 to rotate between the two racks 7. Since the two racks 7 are arranged opposite to each other and both racks 7 are meshed with the gear 8, the rotation of the gear 8 drives the two racks 7 to extend synchronously in opposite directions. Since one end of the rack 7 is hinged to the slider 12, and the slider 12 slides on the outside of the slide rod 11, after the rack 7 is extended, the slider 12 hinged to one end of the rack 7 slides and guides on the outside of the slide rod 11, and the connection between the two extension shovels 3 and the trenching shovel 1 is hinged and rotated, so that the inclination angle between the two extension shovels 3 is synchronously adjusted to ensure that the inclination angle between the two extension shovels 3 is consistent and easy to adjust.

[0030] In a specific embodiment, as shown in the attached Figure 6 , 7 As shown, the two inner walls of the installation frame 6 are both provided with guide grooves 15 , and guide blocks 16 are slidably arranged inside the guide grooves 15 , and the guide blocks 16 are fixedly installed on the outer walls of the corresponding racks 7 .

[0031] Specifically, in this structure, when the two racks 7 extend toward both sides inside the mounting frame 6 , the guide blocks 16 are slidably guided inside the guide grooves 15 , thereby improving the stability of the racks 7 when extending.

[0032] In a specific embodiment, as shown in the attached Figure 4 , 5 As shown, a mounting seat 17 is fixedly provided on the surface of the mounting frame 6, a threaded rod 18 is installed on the internal thread of the mounting seat 17, and a plurality of limiting holes 19 are distributed in an annular shape on the surface of the adjustment block 9, and the threaded rod 18 is structurally compatible with the limiting holes 19.

[0033] Specifically, in this structure, in order to achieve the stability of the entire trench opener during operation, when the adjustment block 9 drives the gear 8 to rotate and the two racks 7 are extended synchronously, the operator rotates the threaded rod 18 so that one end of the threaded rod 18 extends to the inside of the limiting hole 19 opened by the adjustment block 9, thereby limiting and fixing the adjustment block 9, thereby avoiding the adjustment block 9 from rotating during use, thereby improving the stability of the entire trench opener operation.

[0034] From the above, it can be seen that the working principle of the utility model is as follows:

[0035] The utility model provides a furrow opener for agricultural sowing. When furrowing, a screw is passed through a mounting hole 13 on a fixing rod 4 and an agricultural sowing machine, and the fixing rod 4 is installed on the agricultural sowing machine. A sharp end 2 is integrally provided at the outer end of a furrowing shovel 1. The furrowing shovel 1 and the sharp end 2 are inserted into the soil. The agricultural sowing machine drives the furrowing shovel 1 and the sharp end 2 to move, so as to achieve the purpose of furrowing. Since the outer sides of the extended shovel 3 and the furrowing shovel 1 are fixed with a poking pin 14, as the extended shovel 3 and the furrowing shovel 1 move quickly, the poking pin 14 splits the soil, thereby improving the furrowing efficiency.

[0036] When the tilt angle between the two extension shovels 3 needs to be adjusted synchronously to control the trenching width, the operator only needs to rotate the adjustment block 9 to make the gear 8 rotate between the two racks 7. The rotation of the gear 8 drives the two racks 7 to extend synchronously in opposite directions, so that the slider 12 hinged to one end of the rack 7 slides and guides on the outside of the slide rod 11, thereby making the connection between the two extension shovels 3 and the trenching shovel 1 hinged and rotated, thereby adjusting the tilt angle between the two extension shovels 3 synchronously, ensuring that the tilt angle between the two extension shovels 3 is consistent, and the adjustment is convenient, thereby improving the use efficiency;

[0037] After the inclination angles of the two extended shovels 3 are adjusted synchronously, the threaded rod 18 is rotated so that one end of the threaded rod 18 extends to the inside of the limiting hole 19 opened in the adjusting block 9, and the adjusting block 9 is limited and fixed. Since the adjusting block 9 is rotationally restricted, the gear 8 inside the mounting frame 6 will not rotate, and therefore, the rack 7 will not be shifted, thereby preventing the two extended shovels 3 from moving, thereby improving the stability of the entire trencher operation during use.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
