Description

Technical Field

[0001] This utility model applies to the field of soybean planting equipment and provides a depth limiting furrow opener for single-row sowing of soybeans in the field. Background Technology

[0002] As one of the world's most important food crops, soybeans have seen a continuous expansion in global planting area in recent years. With the increasing demand for plant protein and the gradual optimization of agricultural production methods, soybean cultivation has gradually become one of the major agricultural industries. Especially in China, soybean cultivation is not only an important component of food security but also plays a vital role in agricultural restructuring and rural revitalization strategies. Continuous innovation and development in soybean cultivation technology have made positive contributions to increasing yields, improving quality, and promoting agricultural modernization.

[0003] Currently, in soybean cultivation, furrow openers are widely used as important field equipment for soil furrowing and land preparation before sowing. The main function of a furrow opener is to provide suitable furrows for planting through mechanized operation, facilitating seed placement and promoting seed germination and growth. Traditional furrow openers are typically operated manually or mechanically, and their structures vary, including single-row and double-row furrow openers. With the increasing level of agricultural mechanization, modern furrow opener equipment not only achieves efficient furrowing but also possesses strong durability and flexibility, making it suitable for different planting patterns and soil conditions.

[0004] However, in current soybean cultivation, especially in single-row sowing operations, there is a problem with inconvenient depth adjustment. While traditional furrow openers can dig furrows for single-row soybean sowing, their depth setting is often difficult to control precisely. Some equipment requires manual setting of the sowing depth based on experience, which not only increases the complexity of manual intervention but also reduces operational efficiency and sowing uniformity. Therefore, how to achieve precise depth control, especially in single-row sowing operations, has become an urgent technical challenge to be solved. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of this utility model is to provide a depth limiting furrow opener for single-row sowing of soybeans in the field, in order to solve the problems mentioned in the background art. The device includes a mounting base that can be installed on agricultural machinery.

[0006] The mounting base is hingedly connected to a hinge arm and a first hydraulic rod, and the end of the first hydraulic rod away from the mounting base is hingedly connected to the end of the hinge arm away from the mounting base.

[0007] The hinge arm is mounted on a frame at one end away from the mounting base, and a mounting plate is hinged to the other end of the frame away from the hinge arm; one end of the hinge arm is mounted on a second hydraulic rod, and the other end of the second hydraulic rod is hinged to a mounting plate.

[0008] A first lever arm is mounted on the mounting plate, and a trencher is mounted on the bottom of the first lever arm;

[0009] The top of the mounting plate is hinged to the middle of the second lever arm, and one end of the mounting plate is hinged to the third hydraulic rod. The other end of the third hydraulic rod is hinged to one end of the second lever arm. The other end of the second lever arm is equipped with a rotatable roller, and the outer circumference of the roller is evenly distributed with several perforated teeth. The second lever arm can move away from or towards the trencher under the drive of the third hydraulic rod.

[0010] Furthermore, the furrow opener is a plow-shaped furrow opener.

[0011] Furthermore, the mounting base, the first hydraulic rod, and the hinged arm together constitute the trencher lifting mechanism. The trencher lifting mechanism is provided in two sets, and the frame is fixedly connected between the two sets of trencher lifting mechanisms.

[0012] Furthermore, the end of the frame away from the mounting base has a "Y"-shaped fork structure, and the ends of the "Y"-shaped fork structure are all hinged to the mounting plate through the first hinge seat.

[0013] Furthermore, the first lever arm and the second lever arm are each provided with multiple corresponding arms on the mounting plate.

[0014] Furthermore, there are four of each of the first and second lever arms.

[0015] Furthermore, the plurality of rollers are installed synchronously via a linkage shaft.

[0016] This invention enables precise adjustment of the furrow opener's depth and angle, as well as the roller's positioning for sowing, ensuring standardized furrowing and sowing operations. Independent and linked operation of the hydraulic rods improves the accuracy and stability of furrowing depth, inclination angle, and sowing position, which is beneficial for the uniformity of soybean planting and seedling emergence rate. The use of two sets of furrow opener lifting mechanisms and a "Y"-shaped forked frame enhances the support strength of the mounting plate, reduces the risk of damage to the first hinge seat, and improves the device's service life and reliability. The arrangement of multiple first and second lever arms, combined with the synchronization mechanism of the linkage shaft, enables simultaneous operation of multiple rows, significantly improving field operation efficiency. Simultaneously, the roller's perforated tooth design ensures uniform spacing and consistent size of planting holes, promoting the rational distribution and growth of soybean plants, ultimately providing technical support for increased yield and income.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0024] See appendix Figure 1 and attached Figure 2The purpose of this utility model is to provide a depth-limiting furrow opener for single-row sowing of soybeans, including a mounting base 1 that can be fixedly connected to agricultural machinery. The mounting base 1 serves as the connection point between this device and agricultural machinery, and can be bolted to the agricultural machinery, allowing the entire device to operate under the drag of the agricultural machinery.

[0025] A hinged arm 2 and a first hydraulic rod 11 are hingedly connected to the mounting base 1. The end of the first hydraulic rod 11 away from the mounting base 1 is hinged to the end of the hinged arm 2 away from the mounting base 1. Thus, the mounting base 1, the first hydraulic rod 11, and the hinged arm 2 together form a triangular structure. The first hydraulic rod 11 can extend and retract under the power supply of an external device, thereby driving the hinged arm 2 to move on the mounting base 1.

[0026] The end of the articulated arm 2 furthest from the mounting base 1 is fixedly connected to the frame 3. The end of the frame 3 furthest from the articulated arm 2 is hinged to the mounting plate 4 via the first articulated seat 401. One end of the second hydraulic rod 31 is installed between the articulated arm 2 and the first articulated seat 401. The other end of the second hydraulic rod 31 is hinged to the mounting plate 4 via the second articulated seat 402. Thus, the second hydraulic rod 31, the mounting plate 4, and the frame 3 together form a triangular structure. The second hydraulic rod 31 can extend and retract under the power provided by an external device, thereby causing the mounting plate 4 to rotate relative to the frame 3.

[0027] A first lever arm 41 is fixedly connected to the mounting plate 4, and a furrow opener 6, which is a plow-shaped furrow opener, is fixedly connected to the bottom of the first lever arm 41. Driven by agricultural machinery, the furrow opener 6 can perform furrowing operations within a certain height below the ground.

[0028] A second lever arm 42 is hinged to the top of the mounting plate 4. A third hinge seat 403 is fixedly connected to the mounting plate 4. One end of a third hydraulic rod 421 is hinged to the third hinge seat 403. The other end of the third hydraulic rod 421 is hinged to one end of the second lever arm 42. A rotatable roller 5 is mounted on the other end of the second lever arm 42. Several perforated teeth 51 are evenly distributed on the outer circumference of the roller 5. Specifically, the second lever arm 42 can move away from or closer to the trencher 6 under the action of the third hydraulic rod 421.

[0029] Therefore, in actual use, this device can be detachably installed on external agricultural machinery via the mounting base 1. After the device is installed on the agricultural machinery, the first hydraulic rod 11, the second hydraulic rod 31, and the third hydraulic rod 421 can extend and retract under the power provided by the external equipment.

[0030] The first hydraulic rod 11 is mainly responsible for raising and lowering the articulated arm 2. The articulated arm 2 can drive the entire device to rise and fall. When not in use, the working part of the entire device can be lifted off the ground by extending the first hydraulic rod 11. The second hydraulic rod 31 mainly works with the first hydraulic rod 11 to adjust the depth and angle of the trencher 6. The third hydraulic rod 421 mainly adjusts the second lever arm 42 so that the roller 5 at the end of the second lever arm 42 contacts the ground. When the roller 5 is in action, the perforated teeth 51 on the roller 5 can insert into the ground. At the same time, the roller 5 rolls under the action of soil resistance, and several perforated teeth 51 leave planting positioning holes of the same size and interval on the ground in turn. When the roller 5 is in action, the inclination angle of the trencher 6 is not affected. In addition, when the second hydraulic rod 31 is in action, the third hydraulic rod 421 needs to raise the second lever arm 42 to limit the trencher 6 to a designated position before positioning the roller 5.

[0031] Preferably, the mounting base 1, the first hydraulic rod 11, and the hinged arm 2 together constitute the trencher lifting mechanism. The trencher lifting mechanism is provided in two sets, and the frame 3 is fixedly connected between the two sets of trencher lifting mechanisms, thereby making the device itself more robust.

[0032] Preferably, the end of the frame 3 furthest from the mounting base 1 has a "Y"-shaped forked structure, and the ends of the "Y"-shaped forked structures are all hinged to the mounting plate 4 via first hinge seats 401. When the device is in use, the mounting plate 4 is subjected to resistance from the ground, which pulls on the first hinge seats 401, potentially causing them to be damaged due to excessive force. Two first hinge seats 401 can provide better support for the mounting plate 4, increasing the service life of the device.

[0033] Preferably, multiple first lever arms 41 and second lever arms 42 are provided on the mounting plate 4, and they correspond one-to-one. This enables simultaneous depth-limiting furrowing for multiple sowing operations in the soybean field.

[0034] Preferably, there are four of each of the first lever arm 41 and the second lever arm 42.

[0035] Preferably, the plurality of rollers 5 are installed synchronously via a linkage 50, thereby preventing one of the rollers 5 from getting stuck.

[0036] In summary, in actual use, the device is first fixedly installed on the agricultural machinery using the mounting base 1. During the movement of the agricultural machinery, the lifting and lowering of the articulated arm 2 is adjusted by controlling the extension and retraction of the first hydraulic rod 11, thereby raising or lowering the entire device to facilitate lifting it off the ground when not in operation. Subsequently, the extension and retraction of the second hydraulic rod 31 drives the mounting plate 4 to rotate relative to the frame 3 to precisely adjust the soil penetration depth and inclination angle of the trencher 6, ensuring trenching quality. At the same time, the third hydraulic rod 421 actuates, controlling the second lever arm 42 to make the roller 5 contact the ground. The roller 5 rolls under the resistance of the soil, and the perforated teeth 51 on it alternately insert into the ground to form planting positioning holes with uniform spacing and consistent size.

[0037] During this process, the second hydraulic rod 31 and the third hydraulic rod 421 work in coordination: when adjusting the furrow opener 6, the third hydraulic rod 421 first lifts the second lever arm 42 to avoid interfering with the positioning of the furrow opener 6; after the furrow opener 6 is limited to the designated position by the second hydraulic rod 31, the roller 5 is lowered by the third hydraulic rod 421 for spot sowing positioning. In addition, since there are four of each of the first lever arm 41 and the second lever arm 42, which are installed synchronously through the linkage ring 50, spot sowing and furrowing can be performed on multiple rows of soybeans in the field at the same time, improving operational efficiency and consistency.

[0038] Thus, this device achieves precise adjustment of the depth and angle of the furrow opener 6 and the positioning of the roller 5 for sowing, ensuring the standardization of furrowing and sowing operations. The independent and linked operation of the hydraulic rods improves the accuracy and stability of furrowing depth, inclination angle, and sowing position, which is beneficial to the uniformity of soybean planting and the emergence rate. The use of two sets of furrow opener lifting mechanisms and a "Y"-shaped forked frame 3 enhances the support strength of the mounting plate 4, reduces the risk of stress damage to the first hinge seat 401, and improves the service life and reliability of the device. The arrangement of multiple first lever arms 41 and second lever arms 42, combined with the synchronization mechanism of the linkage 50, enables multi-row synchronous operation, significantly improving field operation efficiency. Simultaneously, the design of the perforated teeth 51 of the roller 5 ensures uniform spacing and consistent size of the planting holes, promoting the rational distribution and growth of soybean plants, ultimately providing technical support for increased yield and income.

[0039] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
