Description

Technical Field

[0001] This utility model relates to the field of corn planter technology, and in particular to a corn planter with replaceable furrowing blades. Background Technology

[0002] The furrowing blade of a corn planter is an important component of the planter. It is responsible for creating furrows in the soil so that the planter can accurately place the seeds in the soil. The design and material of the furrowing blade directly affect the working efficiency and service life of the planter. The furrowing blade of a corn planter can have different designs, such as the double disc furrow opener. This design can provide a neat furrowing effect, stable operation, and can adapt to higher operating speeds.

[0003] An existing corn planter with replaceable furrowing blades is prone to wear and damage from hard objects such as stones in the soil, as these parts are in direct contact with the soil during operation. When workers need to adjust or replace the furrowing blades for different soil conditions, it is inconvenient for them to easily install and remove the furrowing blades from the equipment, affecting the normal use and maintenance efficiency of the planter. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a corn planter with replaceable furrowing blades.

[0005] This utility model is achieved by the following technical solution: a corn planter with replaceable furrowing blades, including a connecting frame, a supporting crossbar fixedly connected to the front of the connecting frame, and a fixed column fixedly connected to the top of the supporting crossbar;

[0006] The fixed column is threadedly connected to a limit clasp. A connecting support frame is inserted into the surface of the fixed column. A limit screw is threaded into the interior of the connecting support frame. A fixing plate is threaded into the surface of the limit screw. Side grooving cutters are fixedly connected to the left and right sides of the fixing plate. A support rod is fixedly connected to the top of the support crossbar. A fixing screw is threaded into the interior of the support rod. A limit plate is inserted into the interior of the support rod. A main grooving cutter is fixedly connected to the bottom of the limit plate. An installation rod is fixedly connected to the rear end of the main grooving cutter. A support crossbar is slidably connected to the surface of the installation rod. Installation grooves are provided on the left and right sides of the side grooving cutter. A support frame is engaged inside the installation grooves.

[0007] As a further improvement to the above solution, the bottom of the limiting ring contacts the surface of the connecting support frame, the bottom of the connecting support frame contacts the surface of the supporting crossbar, and the number of fixing plates is set to four, with the four fixing plates symmetrically distributed on the left and right sides with the supporting crossbar as the center.

[0008] Through the above technical solution, when the limiting ring rotates on the surface of the fixed column, it can limit the connecting support frame that is also installed on the surface of the fixed column, thus ensuring the stability of the connecting support frame and the side grooving cutter after installation.

[0009] As a further improvement to the above solution, the number of limiting screws is set to four, and the four limiting screws are symmetrically distributed on the left and right sides with the support crossbar as the center. The fixing screws extend through the support rod and into the interior of the limiting insert plate.

[0010] As a further improvement to the above solution, the number of side grooving cutters is set to two, and the two side grooving cutters are symmetrically distributed on the left and right sides with the support crossbar as the center. The support frame is slidably connected inside the side grooving cutters.

[0011] As a further improvement to the above solution, the connecting screw extends through the support crossbar into the interior of the mounting rod, and the front of the support crossbar contacts the surface of the main trenching cutter.

[0012] Through the above technical solution, the connecting screw can limit and fix the installation rod installed inside the support crossbar, ensuring the stability of the installation rod after the workers connect and fix it.

[0013] As a further improvement to the above solution, the mounting rod is internally threaded with a connecting screw, the limiting plate is internally threaded with a fixing screw, and the bottom of the connecting support frame is in contact with the surface of the fixing plate.

[0014] As a further improvement to the above solution, the rear end of the main trenching cutter is in contact with the surface of the side trenching cutter, and the bottom of the support rod is in contact with the surface of the main trenching cutter.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows the side grooving cutter to be removed from the support rod and limiting plate by rotating the fixing screw, and then from the support crossbar and mounting rod by rotating the connecting screw. Pulling the main grooving cutter, along with the limiting plate and mounting rod, allows it to slide out from the support rod and support crossbar respectively. Finally, rotating the limiting screw allows it to be removed from the connecting support frame and fixing plate, enabling the side grooving cutter to be removed from both sides of the support crossbar. This facilitates convenient installation and removal of the side grooving cutter and main grooving cutter, enhancing operational convenience for workers.

[0017] This invention, by setting an installation groove inside the side grooving cutter, ensures the support stability of the two side grooving cutters when they work together with the main grooving cutter on the front side, so that the side grooving cutters are not squeezed by external forces, thus preventing them from bending and deforming towards each other, and improving the service life of the side grooving cutters.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5 This embodiment of a corn planter with replaceable furrowing blades includes a connecting frame 1, a support crossbar 2 fixedly connected to the front of the connecting frame 1, and a fixed column 3 fixedly connected to the top of the support crossbar 2.

[0028] A limiting ring 4 is threadedly connected to the surface of the fixed column 3. A connecting support frame 5 is inserted into the surface of the fixed column 3. A limiting screw 7 is threadedly connected inside the connecting support frame 5. A fixing plate 6 is threadedly connected to the surface of the limiting screw 7. Side grooving cutters 8 are fixedly connected to the left and right sides of the fixing plate 6. A support rod 9 is fixedly connected to the top of the support crossbar 2. A fixing screw 10 is threadedly connected inside the support rod 9. A limiting insert plate 16 is inserted inside the support rod 9. A main grooving cutter 11 is fixedly connected to the bottom of the limiting insert plate 16. An installation rod 13 is fixedly connected to the rear end of the main grooving cutter 11. A support crossbar 2 is slidably connected to the surface of the installation rod 13. Installation rods 2 are opened on the left and right sides of the side grooving cutter 8. The slide 14 is fitted with a support frame 15. By rotating the fixing screw 10, it can be removed from the support rod 9 and the limiting plate 16. Then, by rotating the connecting screw 12, it can be removed from the support crossbar 2 and the mounting rod 13. Pulling the main trenching cutter 11, in conjunction with the limiting plate 16 and the mounting rod 13, allows it to slide out from the support rod 9 and the support crossbar 2 respectively. By rotating the limiting screw 7, it can be removed from the connecting support frame 5 and the fixing plate 6, so that the side trenching cutter 8 can be removed from the left and right sides of the support crossbar 2. This makes it easy for workers to install and disassemble the side trenching cutter 8 and the main trenching cutter 11, bringing convenience to the workers.

[0029] The bottom of the limiting ring 4 contacts the surface of the connecting support frame 5, and the bottom of the connecting support frame 5 contacts the surface of the supporting crossbar 2. The number of fixing plates 6 is set to four, and the four fixing plates 6 are symmetrically distributed on the left and right with the supporting crossbar 2 as the center.

[0030] When the limiting ring 4 rotates on the surface of the fixed column 3, it can limit the connecting support frame 5, which is also installed on the surface of the fixed column 3, thus ensuring the stability of the connecting support frame 5 and the side grooving cutter 8 after installation.

[0031] The number of limiting screws 7 is set to four. The four limiting screws 7 are symmetrically distributed on the left and right sides with the support crossbar 2 as the center. The fixing screw 10 extends through the support rod 9 and into the interior of the limiting insert plate 16.

[0032] The number of side trenching cutters 8 is set to two, and the two side trenching cutters 8 are symmetrically distributed on the left and right sides with the support crossbar 2 as the center. The support frame 15 is slidably connected inside the side trenching cutter 8. By setting the mounting groove 14 inside the side trenching cutter 8, when the support frame 15 is installed inside the mounting groove 14 and the side trenching cutter 8, the support stability of the two side trenching cutters 8 is ensured when working with the main trenching cutter 11 on the front side. This avoids the side trenching cutter 8 being squeezed by external forces, causing the side trenching cutter 8 to bend and deform towards the end that is close to each other, thus improving the service life of the side trenching cutter 8.

[0033] The connecting screw 12 extends through the support crossbar 2 into the interior of the mounting rod 13, and the front of the support crossbar 2 contacts the surface of the main grooving cutter 11.

[0034] The connecting screw 12 can limit and fix the mounting rod 13 installed inside the support crossbar 2, ensuring the stability of the mounting rod 13 after the workers connect and fix it.

[0035] The mounting rod 13 is internally threaded with a connecting screw 12, the limiting plate 16 is internally threaded with a fixing screw 10, and the bottom of the connecting support frame 5 is in contact with the surface of the fixing plate 6.

[0036] The rear end of the main grooving cutter 11 is in contact with the surface of the side grooving cutter 8, and the bottom of the support rod 9 is in contact with the surface of the main grooving cutter 11.

[0037] The implementation principle of a corn planter with replaceable furrowing blades in this embodiment is as follows: After placing the equipment in a suitable position, the main furrowing blade 11 is removed from the support rod 9 and the limiting plate 16 by rotating the fixing screw 10. Then, it is removed from the support crossbar 2 and the mounting rod 13 by rotating the connecting screw 12. The main furrowing blade 11 is then slid out from the support rod 9 and the support crossbar 2 by pulling the limiting plate 16 and the mounting rod 13 respectively. Finally, it is removed from the connecting support frame 5 and the fixing plate 6 by rotating the limiting screw 7, so that the side furrowing blades 8 are removed from the left and right sides of the support crossbar 2. The two sides can be removed to facilitate the installation and disassembly of the side trenching cutter 8 and the main trenching cutter 11 by the staff, which brings convenience to the staff. By setting the installation groove 14 inside the side trenching cutter 8, when the support frame 15 is installed inside the installation groove 14 and the side trenching cutter 8, the support stability of the two side trenching cutters 8 when working with the main trenching cutter 11 on the front is guaranteed. This avoids the side trenching cutter 8 being squeezed by external forces, which would cause the side trenching cutter 8 to bend and deform towards the end that is close to each other, thus improving the service life of the side trenching cutter 8.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
