Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sowing equipment technology, specifically relating to a field sowing robot. Background Technology
[0002] Agricultural mechanization is an inevitable trend in modern agricultural development. Among them, the mechanization and intelligentization of sowing operations are crucial for improving agricultural production efficiency and reducing labor intensity. At present, various types of sowing machinery are widely used in field sowing operations, from large towed or suspended seeders to small push seeders, and their application is quite common.
[0003] Traditional seeders are typically bulky and have a relatively fixed structure. Taking a common large grain seeder as an example, its working width can reach several meters, and its overall length is also considerable. After completing seeding operations in one field, moving it to another often presents numerous difficulties. Firstly, its excessive width makes it easily restricted, or even impossible, to traverse narrow rural roads, field ridges, or bridges. This necessitates spending considerable time and effort finding suitable routes, severely impacting operational efficiency. Secondly, the large size of the seeder occupies a significant amount of space during transport, requiring large transport vehicles. This not only increases transportation costs but also places high demands on the performance and size of the transport vehicles, further limiting its flexibility for relocation.
[0004] To address the challenges of relocation, some small- to medium-sized or push-type seeding devices have emerged on the market. While these devices are smaller in size, they typically come at the cost of reduced operational efficiency and functionality, making them unsuitable for the high-efficiency seeding needs of large-scale farmland. Therefore, there is an urgent need in this field for a field seeding device that combines high operational efficiency with excellent relocation and storage capabilities to solve these problems.

[0019] 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.
[0020] Example 1 Please see Figures 1-5 The field sowing robot mainly consists of two parts: an unmanned vehicle 1 and a support frame. The unmanned vehicle 1 serves as a mobile platform and power source, and its bottom is equipped with a tracked walking system 11 to adapt to uneven terrain and provide stable traction. A tail plate 13 and two connecting sleeves 14 are fixedly connected to the rear of the unmanned vehicle 1. The support frame is formed by hinged joints of a first mounting frame 2 and a second mounting frame 21, allowing the entire support frame to fold around the hinge point, thus significantly reducing its longitudinal space occupation when not in operation. Insert blocks 22 are hinged to both the first mounting frame 2 and the second mounting frame 21. The insert blocks 22 are adapted to the connecting sleeves 14, and both the insert blocks 22 and the connecting sleeves 14 have connecting holes 24. A limit frame 15 is provided below the tail plate 13, and the lower part of the limit frame 15 has two inserts that can be inserted into the connecting holes 24. A pull rod 16 is fixedly connected to the middle of the limiting frame 15. A spring 17 is installed between the tail plate 13 and the limiting frame 15. The top of the pull rod 16 slides through the tail plate 13, and the spring 17 provides force to ensure that the limiting frame 15 is kept in the locked position. Rollers 23 are provided at the bottom of both the first mounting frame 2 and the second mounting frame 21. A bearing plate 3 is detachably mounted on the bracket. Among them, the unmanned vehicle 1 is an autonomous mobile platform in the prior art, mainly including components such as the vehicle body, battery, control system, power unit and navigation module. Its structure and working principle are well known to those skilled in the art, so they will not be described in detail here.
[0021] Both the first mounting bracket 2 and the second mounting bracket 21 have strip-shaped holes 26 along their length on their surfaces. The bearing plate 3 is mounted on the first mounting bracket 2 and the second mounting bracket 21 through the strip-shaped holes 26, and a side plate 4 is fixedly connected to one side of it. A positioning assembly is provided on the side plate 4, which includes a screw 41 threadedly connected to the side plate 4. Connecting rods 42 are provided on both sides of the screw 41, penetrating the side plate 4. One end of the screw 41 is rotatably connected to a pressure plate 43, and the connecting rods 42 are fixedly connected to the pressure plate 43. The first mounting bracket 2 and the second mounting bracket 21 have side grooves 27 on one side respectively. The side grooves 27 are lined with rubber to increase friction. The pressure plate 43 is adapted to the side grooves 27, and the positioning assembly cooperates with the side grooves 27 to limit the position of the bearing plate 3.
[0022] A complete sowing mechanism is installed above each support plate 3. The sowing mechanism includes a feed hopper 31, a seed metering device 32, a feeding pipe 33, a furrow opener 34, and a covering plate 35. The feed hopper 31 is installed on the upper surface of the support plate 3, the seed metering device 32 is located at the bottom of the feed hopper 31, the feeding pipe 33 is located at the bottom of the seed metering device 32, and the furrow opener 34 and the covering plate 35 are located on both sides of the seed metering device 32. The furrow opener 34 is used to open seed furrows before sowing. After the feeding pipe 33 puts the seeds into the furrows, the covering plate 35 behind it immediately performs the soil covering operation.
[0023] In addition, to improve the range of the unmanned vehicle 1, a photovoltaic panel 12 can be installed on its top platform to replenish the on-board battery on sunny days.
[0024] During operation, firstly, according to the row spacing required for sowing, adjust the position of each bearing plate 3 on the first mounting frame 2 and the second mounting frame 21. Rotate the screw 41 to push the pressure plate 43 to fit with the side groove 27, completing the positioning of the bearing plate 3. After inserting the insert block 22 into the connecting sleeve 14, pull the pull rod 16, compressing the spring 17, so that the insert at the bottom of the limiting frame 15 aligns with the connecting hole 24 on the insert block 22 and the connecting sleeve 14. Then release the pull rod 16, and under the restoring force of the spring 17, the insert at the bottom of the limiting frame 15 inserts into the interior of the connecting hole 24, completing the connection between the bracket and the unmanned vehicle 1. The unmanned vehicle 1 moves through the tracked walking system 11. During the movement, the furrow opener 34 opens furrows, the seed metering device 32 continuously picks up seeds from the hopper 31 and accurately delivers the seeds through the feeding pipe 33, and finally the covering plate 35 performs the soil covering operation.
[0025] During relocation, pull the lever 16 to remove the insert at the bottom of the limiting frame 15 from the connecting hole 24, and then pull the insert 22 out of the connecting sleeve 14 to separate the bracket from the unmanned vehicle 1. Subsequently, rotate the screw 41 in the opposite direction to release the positioning of the bearing plate 3, allowing the bearing plate 3 and the sowing mechanism to be removed from the bracket. The first mounting frame 2 and the second mounting frame 21 can then be folded together around the hinge point, reducing the size of the equipment and greatly saving storage and transportation space, making its transfer more convenient.
[0026] Example 2 Please see Figure 2 , Figure 3 and Figure 5 This embodiment includes the above-described embodiment, and further includes: a limiting rod 18 fixedly connected to the top of one end of the limiting frame 15, and an insertion hole 19 provided on the tail plate 13 to cooperate with the limiting rod 18. The cooperation between the limiting rod 18 and the insertion hole 19 improves the stability of the limiting frame 15 during operation.
[0027] Both the first mounting bracket 2 and the second mounting bracket 21 have limiting holes 28, and a U-shaped bracket 25 is provided between them. When the bracket is unfolded, the two limiting holes 28 will be on the same horizontal plane. At this time, inserting both ends of the U-shaped bracket 25 into the aligned limiting holes 28 will prevent the bracket from tipping over. For further fixation, a magnetic plate 251 is embedded in the inner side of the crossbeam of the U-shaped bracket 25. Since both the first mounting bracket 2 and the second mounting bracket 21 are made of steel, the U-shaped bracket 25 will be firmly attracted by the magnetic plate 251 after insertion, preventing the U-shaped bracket 25 from falling off during use and improving the stability of the bracket during use.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
