[0001] This utility model relates to the field of fruit sowing technology, specifically to an intermittent fruit seed sowing device. Background Technology

[0002] To ensure the sustainability and yield of the fruit industry, fruit seeds need to be planted in the soil to cultivate new seedlings. These seedlings, once they grow into new fruit trees, can continue to propagate and produce fruit, thus supporting the continued development of the fruit industry. Sowing is therefore an indispensable step in the fruit cultivation process.

[0003] A search revealed that Chinese patent application CN220986608U discloses a small seed planter. This addresses the problems of existing planters where, due to the small size of the seeds, the seed position cannot be adjusted according to the required sowing distance, resulting in dense sowing that is detrimental to seed growth. Furthermore, it requires manual covering with soil after sowing, indicating a low level of automation.

[0004] However, the following technical problems still exist when implementing the above technical solutions: the soil depth required for seeds of different fruits is different in actual planting. Therefore, in actual operation, sowing should be carried out according to the sowing depth required for different fruit seeds. However, the seeder in the above solution cannot achieve free adjustment of sowing depth.

[0005] Therefore, a utility model of an intermittent fruit seed sowing device is urgently needed to solve the problem of ensuring that seeds are sown at certain intervals and times during use, which is beneficial to fruit growth and yield control, while adapting to planting needs at different depths and increasing the versatility and flexibility of the device.

[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0034] Reference Figures 1-6 As shown, an intermittent fruit seed sowing device includes: a mounting plate 100, on which a sowing tube 103 for storing fruit seeds is fixedly mounted; an intermittent sowing mechanism 300 for intermittent sowing is provided in the sowing tube 103, which can be raised and lowered vertically; and a height-adjustable lifting mechanism 200 for digging planting troughs is also provided on the mounting plate 100 in front of the sowing tube 103. The lifting mechanism 200 includes: a grooving plate 207, on which a lifting rod 204 is fixedly mounted; and a driving component for driving the grooving plate 207 to rise and fall.

[0035] In use, fruit seeds are poured into the sowing tube 103. The height of the lifting mechanism 200 is adjusted according to planting needs, i.e., the vertical position of the grooving plate 207 is adjusted to determine the depth of the planting trough. The drive mechanism is activated, driving the lifting rod 204 in the lifting mechanism 200 to lower the grooving plate 207 to the soil surface, where the grooving plate 207 excavates a planting trough in the soil. Simultaneously, the intermittent sowing mechanism 300 moves vertically up and down within the sowing tube 103, releasing a certain number of seeds into the excavated planting trough with each movement. The design of the intermittent sowing mechanism 300 ensures that seeds are sown at specific intervals and times, achieving intermittent sowing. Through the coordinated work of the intermittent sowing mechanism 300 and the lifting mechanism 200, automated sowing and grooving are achieved, greatly improving sowing efficiency and reducing labor costs. The design of the intermittent sowing mechanism 300 ensures that seeds are sown at specific intervals and times, which is beneficial for fruit growth and yield control; the adjustable height of the lifting mechanism 200 allows the sowing device to adapt to planting depths, increasing the versatility and flexibility of the device.

[0036] Reference Figures 2-3 As shown, the driving component includes: a rotating shaft 201, a rotary motor 203, and a driving rod 206; wherein, the rotary motor 203 is fixedly mounted on the mounting plate 100, the output shaft of the rotary motor 203 is vertically upward and its top end is fixedly connected to the rotating shaft 201 through a coupling, the circumferential surface of the rotating shaft 201 is provided with an arc-shaped driving groove 202, and the circumferential surface of the lifting rod 204 is fixedly provided with a driving rod 206 that cooperates with the driving groove 202.

[0037] When the height of the lifting mechanism 200 needs to be adjusted, the rotary motor 203 is started, and the drive groove 202 cooperates with the drive rod 206: the output shaft of the rotary motor 203 drives the rotating shaft 201 to rotate, and the arc-shaped drive groove 202 opened on the circumferential surface of the rotating shaft 201 rotates accordingly. At this time, the drive rod 206, which is fixed to the circumferential surface of the lifting rod 204, slides in the drive groove 202. Since the drive groove 202 is arc-shaped, the sliding of the drive rod 206 is converted into the lifting motion of the lifting rod 204. As the drive rod 206 slides in the drive groove 202, the lifting rod 204 drives the grooving plate 207 to rise or fall, thereby adjusting the excavation depth of the planting trough and meeting the planting needs at different depths.

[0038] Reference Figure 3 As shown, a spring 205 is sleeved on the lifting rod 204, with its two ends respectively abutting against the upper surface of the mounting plate 100 and the surface of the driving rod 206.

[0039] In the above scheme, when the lifting mechanism 200 rises, the spring 205 is stretched; when the lifting mechanism 200 descends, the spring 205 releases energy to assist the lifting mechanism 200 in descending smoothly. At the same time, the spring 205 can also act as a buffer when the lifting mechanism 200 is subjected to external impact, protecting the lifting mechanism 200 from damage.

[0040] Reference Figures 4-6 As shown, the intermittent sowing mechanism 300 includes: a lifting cylinder 301, a connecting rod 302, a limiting rod 305, and a limiting plate 306; wherein, the lifting cylinder 301 is provided inside the sowing tube 103, the upper and lower surfaces of the lifting cylinder 301 are both fixedly provided with the limiting plate 306, and the connecting rod 302 is fixedly connected to the upper surface. The circumferential surface of the lifting cylinder 301 is provided with a feeding groove 303 that penetrates the lower surface limiting plate 306. The mounting plate 100 is provided with a driving component 400 for driving the connecting rod 302 to rise and fall so that the fruit seeds fall out of the sowing tube 103 through the feeding groove 303 for sowing.

[0041] In the above scheme, when sowing is required, the drive assembly 400 is activated, driving the lifting cylinder 301 to rise and fall within the sowing tube 103 via the connecting rod 302. The rising and falling motion of the lifting cylinder 301 aligns or offsets the feeding trough 303 on its circumferential surface with the material storage area at the upper end of the sowing tube 103, thereby controlling the seed discharge. As the lifting cylinder 301 rises and falls, when the feeding trough 303 aligns with the outlet of the sowing tube 103, the fruit seeds fall out of the sowing tube 103 through the feeding trough 303, completing one sowing cycle. Then, the drive assembly 400 continues to drive the lifting cylinder 301 to rise and fall, offsetting the feeding trough 303 from the outlet of the sowing tube 103, preventing further seed discharge, and achieving intermittent sowing.

[0042] Reference Figures 5-6 As shown, the circumferential surface of the connecting rod 302 is provided with a plurality of limiting grooves 304 spaced apart, and the seeding tube 103 is fixedly provided with a number of limiting rods 305 that are the same as the limiting grooves 304 and correspond one-to-one.

[0043] In the above scheme, during the lifting and lowering process of the lifting cylinder 301, multiple limiting grooves 304 spaced apart on the circumferential surface of the connecting rod 302 cooperate with the limiting rods 305 fixedly installed on the seeding tube 103 in the same number and corresponding order. The limiting rods 305 can be inserted into the limiting grooves 304 to limit the lifting height and position of the lifting cylinder 301. When the limiting rods 305 are inserted into the limiting grooves 304, the lifting and lowering action of the lifting cylinder 301 becomes more stable, reducing the problem of inaccurate seeding caused by shaking or deviation. At the same time, the cooperation between the limiting rods 305 and the limiting grooves 304 can also play a guiding role, ensuring that the lifting cylinder 301 maintains the correct orientation during the lifting and lowering process.

[0044] Reference Figures 1-2As shown, the bottom surface of the mounting plate 100 is provided with multiple sets of drive wheels 101 at intervals, and the mounting plate 100 is fixedly provided with a drive motor 102 whose output shaft is fixedly connected to the drive shaft of the drive wheels 101.

[0045] When the seeding device needs to be moved, the drive motor 102 fixedly mounted on the mounting plate 100 is started. The output shaft of the drive motor 102 is fixedly connected to the drive shaft of the drive wheel 101. Therefore, the rotation of the drive motor 102 will drive the drive wheel 101 to rotate. Multiple sets of drive wheels 101 rotate at intervals on the bottom surface of the mounting plate 100 to provide forward power for the seeding device.

[0046] Reference Figure 2 and Figure 6 As shown, the drive assembly 400 includes: a rotating shaft 402, a cam 403, and a baffle 404; wherein, the top end of the connecting rod 302 is fixedly provided with a baffle 404, the mounting plate 100 is rotatably provided with a bracket for the rotating shaft 402, the top end of the rotating shaft 402 is fixedly provided with a cam 403 whose surface contacts the baffle 404, and the rotating shaft 402 is connected to the drive shaft of the drive wheel 101 through a transmission belt 401.

[0047] During the sowing process, the drive motor 102 is started, and the drive wheel 101 rotates, driving the rotating shaft 402 to rotate via the transmission belt 401. A cam 403 is fixedly installed at the top of the rotating shaft 402. As the rotating shaft 402 rotates, the surface of the cam 403 contacts the baffle 404 at the top of the connecting rod 302 and pushes it up and down. The up and down movement of the baffle 404 drives the lifting cylinder 301 to rise and fall within the sowing tube 103 via the connecting rod 302, thereby achieving intermittent sowing. When the protruding part of the cam 403 contacts the baffle 404, the lifting cylinder 301 rises, and the discharge chute 303 is misaligned with the outlet of the sowing tube 103, preventing the seeds from falling out. When the concave part of the cam 403 contacts the baffle 404, the lifting cylinder 301 falls, and the discharge chute 303 is aligned with the outlet of the sowing tube 103. The seeds fall out through the discharge chute 303 for sowing. As the cam 403 continues to rotate, the lifting cylinder 301 continuously rises and falls, achieving intermittent sowing.

[0048] Reference Figures 1-2 As shown, a soil covering plate 105 is fixedly installed on the bottom surface of the mounting plate 100 behind the seeding pipe 103.

[0049] In the above scheme, as the sowing device or the sowing tube 103 moves, the soil covering plate 105 located behind the sowing tube 103 also moves. The soil covering plate 105 gently covers the seeds with the sown soil, ensuring that the seeds are properly buried.

[0050] Reference Figures 1-2As shown, a watering mechanism 500 is fixedly installed on the mounting plate 100 behind the soil covering plate 105; wherein, the watering mechanism 500 includes: a water storage tank 501 and a connecting pipe 502; the water storage tank 501 is fixedly installed on the upper surface of the mounting plate 100, and a nozzle 503 is fixedly connected to the side of the water storage tank 501 through the connecting pipe 502.

[0051] Before the sowing operation begins, an appropriate amount of water is added to the water storage tank 501 to prepare for the subsequent watering operation. After the sowing and covering operations are completed, the water in the water storage tank 501 is transported to the nozzle 503 through the connecting pipe 502. The nozzle 503 sprays the water evenly on the soil after sowing. As the sowing device moves, the watering operation covers the entire sowing area until the watering task is completed.

[0052] Reference Figures 1-2 As shown, a handle 104 is also fixedly provided on the mounting plate 100.

[0053] During the use of the seeding device, the operator can easily move or control the position and direction of the seeding device by holding the handle 104. By holding the handle 104, the operator can control the seeding device more stably and reduce the safety risks caused by improper operation.

[0054] In summary, the intermittent fruit seed sowing device provided by this utility model involves pouring fruit seeds into the sowing tube 103 to ensure sufficient seeds, starting the drive motor 102, and moving the entire sowing device to the predetermined sowing position via the drive wheel 101. According to the sowing depth requirements, the rotating shaft 201 is driven to rotate by the rotary motor 203. Then, through the cooperation of the drive groove 202 and the drive rod 206, the height of the grooving plate 207 is adjusted and lowered to the soil surface. As the device moves, it excavates planting troughs. The spring 205 plays a buffering and stabilizing role in the process, ensuring that the grooving plate 207 descends smoothly and excavates uniform planting troughs. After the planting troughs are excavated, the drive wheel 101 drives the rotating shaft 402 to rotate via the transmission belt 401, which in turn causes the cam 403 to rotate. The rotation of the cam 403 pushes the baffle 404 and the connecting rod 302 to rise, thereby driving the lifting cylinder 301 to rise. At this time, the fruit seeds in the lifting cylinder 301 fall out of the sowing tube 103 through the feeding trough 303 and into the planting trough. The cam 403 continues to rotate. When it separates from the baffle 404, the lifting cylinder 301 descends back to its original position due to gravity, ready for the next sowing. The cooperation of the limiting rod 305 and the limiting groove 304 ensures the stability of the lifting cylinder 301 during the lifting process. After sowing is completed, the sowing device continues to move. The soil covering plate 105 covers the soil on the planting trough and the seeds. When it moves above the watering mechanism 500, the water in the water storage tank 501 is sprayed onto the soil through the connecting pipe 502 and the nozzle 503 to provide the seeds with the necessary moisture.

However, the present invention is not limited to the specific details of the above embodiments.
