Description

Technical Field

[0001] This utility model relates to the field of no-till planter technology, specifically a no-till planter for wheat intercropping with corn. Background Technology

[0002] No-till planters are core agricultural machinery equipment adapted to the needs of modern agriculture's "conservation tillage" practices. They can complete the entire process of ditching, seeding, fertilizing, covering, and compacting in one operation without tilling, effectively reducing soil disturbance and water loss, aligning with the trend of green agriculture. Currently, no-till planters are widely used in dryland farming of crops such as corn, soybeans, and wheat, especially in arid and semi-arid regions of northern my country and in large-scale planting bases, becoming an important equipment support for promoting cost reduction, quality improvement, and increased yield in agricultural production.

[0003] However, current no-till planters have significant technical defects in their existing furrowing blade structure when operating on fields covered with stubble from crops such as corn and wheat. The specific problems are as follows: First, when the ditching blade penetrates the surface straw layer, the straw easily becomes entangled near the blade body. Since the straw is mostly 10-30cm long and has a certain degree of toughness, it easily forms a tight "clump" that cannot fall off naturally. Second, the "clump" directly increases the resistance of the ditching blade into the soil, preventing it from penetrating to the preset depth, resulting in a ditch depth 2-5cm shallower than designed. Third, the entangled "clump" disrupts the normal cutting trajectory of the ditching blade, causing irregular protrusions or deviations in the shape of the ditch, which in turn causes subsequent seeding and fertilization to deviate, increases the risk of seed-fertilizer contact, and affects the uniformity of soil covering, ultimately leading to a 5%-8% decrease in crop germination rate. Currently, there is no effective structural design for ditching blades that solves the above problems. Existing anti-entanglement solutions are mostly simple additions of comb teeth, which can only handle short straw and are insufficient to inhibit the entanglement of long stubble from corn and wheat, making it difficult to meet the needs of efficient and precise ditching in no-till fields. Utility Model Content

[0004] The purpose of this invention is to provide a no-till planter for wheat-corn intercropping to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A wheat-corn intercropping no-till planter includes a blade arm and a furrowing blade. The bottom of the furrowing blade is fixedly connected to a mounting handle, which is fixedly installed at the bottom end of the blade arm. A cutting groove is formed at the top of the mounting handle, which runs horizontally through the mounting handle, and the groove opening is formed between the blade arm and the furrowing blade. The extension direction of the cutting groove is consistent with the length direction of the cutter arm, and a pressure block is slidably provided on the cutter arm; A cutting blade is fixedly provided on the inner bottom surface of the groove, with the cutting edge of the cutting blade facing the pressure block; The pressing block is driven by a drive device to repeatedly enter the cutting groove along the length of the cutter arm, so as to cooperate with the cutter to cut the straw stuck inside the cutting groove.

[0006] Preferably, the bottom of the pressure block is provided with a clearance groove, and when the pressure block moves to the lowest position, at least part of the cutter is located inside the clearance groove.

[0007] Preferably, the bottom of the cutter is fixedly connected to a mounting base, and the mounting base is fixedly mounted on the mounting handle.

[0008] Preferably, a guide rod is fixedly connected to the pressure block, the axial direction of the guide rod is parallel to the length direction of the cutter arm, at least two guide sleeves are slidably connected to the guide rod, the guide sleeves are installed on the cutter arm, and the driving device is used to drive the guide rod to reciprocate along its own axial direction.

[0009] Preferably, the driving device includes a cam mechanism and a compression spring, and a retaining ring is fixedly sleeved on the guide rod; The compression spring is sleeved on the guide rod, and its two ends abut against the retaining ring and one of the guide sleeves, respectively.

[0010] Preferably, the cam mechanism includes a drive shaft and a cam, the drive shaft being connected to the power shaft on the no-till planter, and the cam being fixedly connected to the drive shaft and used to push the guide rod to move.

[0011] Preferably, the cam mechanism further includes a protective housing, which is mounted on the no-till planter.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the design of a cutting groove, a cutter, and a pressing block, allows the driving device to repeatedly drive the pressing block into the cutting groove during the trenching operation. This pushes the straw wrapped around the blade arm into the cutting groove and cuts it with the help of the cutter. The cut straw then falls off the blade arm, thus solving a series of technical problems caused by straw wrapping around the blade arm. This ensures that the trenching depth reaches the predetermined value and that the trenches do not have irregular protrusions or deviations, thereby guaranteeing the seed germination rate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: This is a no-till wheat-corn intercropping planter. The planter includes a seed box, a seed metering device, a drive shaft, and a gearbox. The seed box stores seeds, the seed metering device dispenses seeds to predetermined positions at a suitable speed, and the drive shaft and gearbox transmit power. Additionally, the planter includes a cutter arm 1 and a furrowing cutter 2. A mounting handle 3 is fixedly connected to the bottom of the furrowing cutter 2 and is fixedly mounted on the bottom end of the cutter arm 1. The furrowing cutter 2 and the mounting handle 3 can be fixed together by welding, or the mounting handle 3 and the cutter arm 1 can be fixed together using bolts or other fasteners. These are all existing technologies and will not be elaborated upon further.

[0017] Unlike existing technologies, the top of the mounting handle 3 is provided with a cutting groove 4, which runs horizontally through the mounting handle 3, and the opening of the cutting groove 4 is formed between the blade arm 1 and the furrowing blade 2. In this embodiment, the direction of movement of the no-till seeder under the traction of the traction device can be defined as the front-back direction. Therefore, the cutting groove 4 runs through the mounting handle 3 from the left-right direction.

[0018] The extension direction of the groove 4 is consistent with the length direction of the cutter arm 1. As can be seen from the figure, the cutter arm 1 has a certain degree of inclination, therefore the groove 4 also has a certain degree of inclination. Figure 4 As shown, the bottom of the pressing block 6 is provided with a relief groove 601. When the pressing block 6 moves to the lowest position, at least part of the cutter 5 is located inside the relief groove 601. The relief groove 601 is provided to ensure the cutting rate of the straw by the cutter 5 and to protect the cutting edge of the cutter 5.

[0019] A pressure block 6 is slidably mounted on the blade arm 1; a cutter 5 is fixedly mounted on the inner bottom surface of the cutting groove 4, with the cutting edge of the cutter 5 facing the pressure block 6. In this embodiment, a mounting base 7 is fixedly connected to the bottom of the cutter 5, and the mounting base 7 is fixedly mounted on the mounting handle 3 by bolts or other fasteners, which facilitates the installation and removal of the cutter 5; the pressure block 6 is driven by a driving device to repeatedly enter the cutting groove 4 along the length direction of the blade arm 1, so as to cooperate with the cutter 5 to cut the straw stuck inside the cutting groove 4.

[0020] In the above solution, through the setting of the cutting groove 4, the cutter 5, and the pressing block 6, during the trenching operation of the trenching knife 2, the driving device will drive the pressing block 6 to repeatedly enter the cutting groove 4, so that the straw wrapped around the knife arm 1 is pushed into the cutting groove 4 by the pressing block 6 and cut in conjunction with the cutter 5. The cut straw will then fall off the knife arm 1, thereby solving a series of technical problems caused by straw wrapping around the knife arm 1, ensuring that the trenching depth reaches the predetermined value, and that the trenches opened will not have irregular protrusions or deviations, thus ensuring the seed germination rate.

[0021] A guide rod 8 is fixedly connected to the pressure block 6. The axial direction of the guide rod 8 is parallel to the length direction of the cutter arm 1. At least two guide sleeves 9 are slidably connected to the guide rod 8. The guide sleeves 9 are installed on the cutter arm 1 by fasteners such as bolts. The driving device is used to drive the guide rod 8 to reciprocate along its own axial direction.

[0022] The drive mechanism includes a cam mechanism and a compression spring 13. A retaining ring 12 is fixedly sleeved on the guide rod 8. The compression spring 13 is sleeved on the guide rod 8, and its two ends abut against the retaining ring 12 and one of the guide sleeves 9, respectively. When the guide rod 8 and the pressure block 6 move toward the groove 4, the compression spring 13 is compressed to generate a rebound force. This rebound force is used to push the pressure block 6 away from the groove 4, thereby achieving the purpose of the pressure block 6 repeatedly entering the groove 4.

[0023] The cam mechanism includes a drive shaft 10 and a cam 11. The drive shaft 10 is connected to the power shaft on the no-till seeder. For example, the drive shaft 10 and the power shaft on the no-till seeder can be connected by a gear set. Gear sets are a commonly used power transmission technology in this field, so they will not be described in detail. The cam 11 is fixedly connected to the drive shaft 10 and is used to push the guide rod 8 to move. Furthermore, the cam mechanism also includes a protective housing 14, which is installed on the no-till seeder. Both the drive shaft 10 and the cam 11 are located inside the protective housing 14.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
