Simultaneously, new straight lines can be drawn as indicators for the next advance, ensuring the direct seeding machine maintains a straight line throughout the entire seeding process.

Description

Technical Field

[0001] This utility model relates to a direct seeding machine, belonging to the field of agricultural machinery technology, and particularly to a hand-push type rice direct seeding machine. Background Technology

[0002] The initial production process of rice involves sowing and raising seedlings in paddy fields. Due to the high labor intensity and workload of sowing and the tight agricultural schedule, mechanical seeders are needed for rice sowing. However, mechanical seeders are generally complex in structure and large in size, making them unsuitable for use in small paddy fields. To improve convenience, hand-push rice direct seeders are generally used for sowing in paddy fields.

[0003] For example, the rice direct seeding machine disclosed in Chinese patent CN203646024U is operated by a person pulling a lever to move forward in the paddy field and uses multiple seed buckets arranged side by side for sowing. However, this type of direct seeding machine still has the following problems:

[0004] Because rice seeds need to be planted at a suitable spacing to absorb the appropriate amount of water and nutrients for germination and growth, it is necessary to maintain a consistent row spacing when planting rice. However, this rice direct seeding machine is manually pulled forward. During the forward movement, due to the lack of guiding tools, the operator walks in a straight line by feeling, resulting in the actual walking route not being a straight line, which in turn causes changes in the row spacing of the rice. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects and problems of existing rice direct seeders that cannot maintain straight-line movement, and to provide a hand-push rice direct seeder that can maintain straight-line movement.

[0006] To achieve the above objectives, the technical solution of this utility model is: a hand-push rice direct seeding machine, including a base, a seeding bin, and a handle. The handle is connected to one side of the base. Multiple support rods are spaced apart along the width direction on the base. One end of each support rod is rotatably connected to a rotating rod. One end of the rotating rod is connected to a rotating wheel, and the other end of the rotating rod is connected to a seeding wheel. The seeding wheel has multiple seeding slots spaced apart along its circumference for accommodating seeds. The seeding bin is installed on the upper side of the support rods. The seeding bin is located above the seeding wheel, and its outlet is arranged relative to the seeding slots. An indicator rod is installed on the base. Positioning rods are hinged to the left and right sides of the base. Marking hooks are connected to the lower sides of both the positioning rod and the indicator rod.

[0007] The base includes a pull rod, a horizontally arranged support plate, and a connecting plate. The handle is connected to one side of the support plate, and the connecting plate is hinged to the other side of the support plate. A column is vertically connected to the connecting plate, and a sleeve is horizontally connected to the upper end of the column. The two ends of the pull rod are respectively movably connected to the sleeve and the handle.

[0008] The handle includes two symmetrically arranged grips and a connecting rod. The connecting rod is horizontally arranged and connected between the two grips. The two ends of the pull rod are connected to hooks, one of which is sleeved on the sleeve rod and the other of which is sleeved on the connecting rod.

[0009] The outer circumference of the connecting rod is symmetrically connected to two clamping plates, and another hook of the pull rod is located between the two clamping plates.

[0010] The other end of the support rod is rotatably connected to the upper side of the base via a support seat. The support seat includes two limiting plates and a rotating shaft. The two limiting plates are symmetrically arranged and vertically connected to the upper side of the connecting plate. The rotating shaft is horizontally arranged and connected to the two limiting plates at both ends. The other end of the support rod is sleeved on the rotating shaft.

[0011] A baffle is installed on the upper side of the support rod. The baffle includes a first clamping plate and a second clamping plate. Both the first clamping plate and the second clamping plate are arc-shaped. The first clamping plate is arranged relative to the outer circumferential surface of the seeding wheel, and the second clamping plate is arranged at an angle and relative to the end face of the seeding wheel.

[0012] One end of the positioning rod is connected to a universal joint, and the left and right sides of the positioning rod are connected to clamping plates. The universal joint is connected to the upper side of the support plate, and the two clamping plates are symmetrically arranged on the upper side of the support plate.

[0013] Two mounting plates are vertically connected to the support plate, and the indicator rod is inserted between the two mounting plates. The mounting plate has a pin hole, and a positioning pin is threaded into the pin hole. The positioning pin is threaded into the indicator rod.

[0014] A bracket is connected to the upper side of the support rod, and an installation box is connected to the upper side of the bracket. The installation box matches the shape of the seeding wheel, and a slot is opened on the upper side of the installation box, into which the seeding chamber is inserted.

[0015] A brush is connected to the inside of the mounting box, and the brush is arranged relative to the outer circumferential surface of the seeding wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, a hand-push rice direct seeding machine uses a marking hook on a positioning rod to pre-draw a straight line in the paddy field. During sowing, the marking hook on the indicator rod is aligned with this line, allowing the machine to move along the straight line and maintain a consistent path. Simultaneously, another marking hook on a positioning rod draws a straight line in the paddy field. After the machine turns, the marking hook on the other indicator rod is aligned with the next straight line drawn by the other positioning rod. Each time the machine moves forward, it aligns with the previously drawn lines, and simultaneously draws new straight lines as indicators for the next movement, ensuring the direct seeding machine maintains a straight path throughout the sowing process. Therefore, this utility model enables the machine to maintain straight-line movement.

[0018] 2. In this hand-push rice direct seeding machine, a connecting plate can be pulled by a lever, which in turn causes multiple seeding wheels to tilt upwards, stopping the seeding process. This avoids wasting seeds when turning. A clamping plate limits the lever's movement, preventing it from sliding left or right as the machine advances. Each support rod is individually connected to the connecting plate via a rotating mechanism. When encountering stones or clods of soil in the paddy field, the corresponding rotating wheel can easily pass over them, while the other wheels rotate normally, ensuring stable forward movement of the direct seeding machine. Therefore, this invention features a simple structure, high stability, and ease of use.

[0019] 3. In this utility model of a hand-push rice direct seeding machine, a baffle is installed. After the rice seeds fall into the sowing trough, they are limited by the baffle. After the sowing trough rotates to the bottom, the rice seeds are released from the restriction of the baffle and fall, thus allowing the seeds to fall stably for sowing. The baffle also ensures that the positioning rod is always in a horizontal state, thereby stabilizing the marking process. A brush is installed to brush the seeds falling on the surface of the sowing wheel into the sowing trough. Therefore, this utility model has high reliability and a wide range of applications.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] See Figure 1 A hand-push rice direct seeding machine includes a base 1, a seeding chamber 10, and a handle 9. The handle 9 is connected to one side of the base 1. Multiple support rods 2 are spaced apart along the width direction on the base 1. One end of each support rod 2 is rotatably connected to a rotating rod 3. One end of the rotating rod 3 is connected to a rotating wheel 4, and the other end of the rotating rod 3 is connected to a seeding wheel 5. The seeding wheel 5 has multiple seeding grooves 51 spaced apart along its circumference for holding seeds. The seeding chamber 10 is installed on the upper side of the support rods 2. The seeding chamber 10 is located above the seeding wheel 5, and its outlet is arranged relative to the seeding grooves 51. Two indicator rods 7 are symmetrically installed on the base 1. Positioning rods 8 are hinged to the left and right sides of the base 1. Marking hooks 110 are connected to the lower side of both the positioning rods 8 and the indicator rods 7.

[0032] In this embodiment, the marking hook 110 adopts a hook-shaped design. The distance from the marking hook 110 on the positioning rod 8 to the outermost support rod 2 is the same as the distance from the marking hook 110 on the indicator rod 7 to the outermost support rod 2. Thus, when turning after marking a straight line, since the marking hook 110 marks the line on the outside of the direct seeding machine, there is a certain distance between the outermost seeding bin 10 and the straight line. Since the distances of the two marking hooks 110 are the same, after aligning the marking hook 110 on the indicator rod 7 with the straight line, the row spacing between the second sowing and the first sowing is exactly the row spacing between each rice plant, thereby keeping the overall row spacing consistent.

[0033] See when sowing Figure 2 The arrow indicates the direction of movement of the direct seeding machine. Rotate the right positioning rod 8 onto the base 1 and install the right indicator rod 7. Align the indicator rod 7 with the previously drawn straight line. At the same time, rotate the left positioning rod 8 so that the line hook 110 contacts the paddy field. Then, pull the handle 9 to move forward. During the forward movement, observe the right indicator rod 7 to move in a straight line. The rotating wheel 4 starts to rotate at the same time. Since the rotating wheel 4 and the seeding wheel 5 are connected through the rotating rod 3, the seeding wheel 5 will rotate. The seeds in the seeding bin 10 fall into each seeding trough 51. When the seeding trough 51 rotates below the horizontal line, the seeds fall into the paddy field for sowing due to gravity.

[0034] See Figure 3 When sowing reaches the edge of the paddy field, the machine turns. Before turning, the marking hook 110 of the left positioning rod 8 marks a straight line in the paddy field. After turning, the left indicator rod 7 is installed, and the marking hook 110 of the indicator rod 7 is aligned with this straight line. Then, the left positioning rod 8 is rotated onto the base 1, and the right positioning rod 8 is rotated so that the marking hook 110 of the right positioning rod 8 contacts the paddy field. Then, the machine moves forward by pulling the handle 9. During the forward movement, the machine moves in a straight line by observing the left indicator rod 7. At the same time, the marking hook 110 of the right positioning rod 8 marks a straight line in the paddy field. This straight line can serve as the indicator line for the direct seeding machine after the next turn. By repeatedly marking straight lines and aligning with the marked straight line, the direct seeding machine can maintain a straight line throughout the entire sowing process.

[0035] Example 2:

[0036] The basic content is the same as in Example 1, except that:

[0037] See Figure 4The base 1 includes a pull rod 11, a horizontally arranged support plate 12, and a connecting plate 13. The handle 9 is connected to one side of the support plate 12, and the connecting plate 13 is hinged to the other side of the support plate 12 via a hinge 14. A column 15 is vertically connected to the connecting plate 13, and a sleeve rod 16 is horizontally connected to the upper end of the column 15. The two ends of the pull rod 11 are respectively movably connected to the sleeve rod 16 and the handle 9.

[0038] The handle 9 includes two symmetrically arranged grip rods 91 and a connecting rod 92. The connecting rod 92 is horizontally arranged and connected between the two grip rods 91. The two ends of the pull rod 11 are connected to hooks 17, one hook 17 is sleeved on the sleeve rod 16, and the other hook 17 is sleeved on the connecting rod 92.

[0039] The outer periphery of the connecting rod 92 is symmetrically connected to two clamping plates 93, and the other hook 17 of the pull rod 11 is located between the two clamping plates 93.

[0040] In this embodiment, during sowing, the direct seeding machine is moved by pulling the handle 91. When it is necessary to stop sowing, the hook 17 of the pull rod 11 can be connected to the sleeve rod 16. Pulling the pull rod 11 causes the connecting plate 13 to rotate on the support plate 12. After the other hook 17 of the pull rod 11 is sleeved on the connecting rod 92, the pull rod 11 is fixed. At this time, the connecting plate 13 is lifted, and the sowing chamber 10 is in an inclined state and the seeds cannot fall.

[0041] Example 3:

[0042] The basic content is the same as Example 2, except that:

[0043] See Figure 5 and Figure 6 The other end of the support rod 2 is rotatably connected to the upper side of the base 1 via a support seat 18. The support seat 18 includes two limiting plates 181 and a rotating shaft 182. The two limiting plates 181 are symmetrically arranged and vertically connected to the upper side of the connecting plate 13. The rotating shaft 182 is horizontally arranged and its two ends are connected to the two limiting plates 181. The other end of the support rod 2 is sleeved on the rotating shaft 182.

[0044] A bracket 21 is connected to the upper side of the support rod 2, and an installation box 22 is connected to the upper side of the bracket 21. The installation box 22 matches the shape of the seeding wheel 5. A slot 23 is provided on the upper side of the installation box 22, and the seeding chamber 10 is inserted into the slot 23. A brush 24 is connected to the inner side of the installation box 22, and the brush 24 is arranged relative to the outer circumferential surface of the seeding wheel 5.

[0045] In this embodiment, the distance between the two limiting plates 181 is exactly the same as the width of the support rod 2, which can prevent the support rod 2 from sliding left and right on the rotating shaft 182. One side of the bracket 21 is installed on the support rod 2, and the other side is sleeved on the rotating rod 3. The upper end face of the sowing wheel 5 can be sealed with a bin cover. When sowing, the bin cover can be opened and seeds can be poured in. The seeds fall from the sowing bin 10 onto the sowing wheel 5. Since the sowing wheel 5 is rotating, the mounting box 22 is relatively stationary. Thus, the seeds can be brushed into the sowing trough 51 by the brush 24.

[0046] Example 4:

[0047] The basic content is the same as in Example 1, except that:

[0048] See Figure 7 A baffle 6 is installed on the upper side of the support rod 2. The baffle 6 includes a first clamping plate 61 and a second clamping plate 62. Both the first clamping plate 61 and the second clamping plate 62 are arc-shaped. The first clamping plate 61 is arranged relative to the outer peripheral surface of the seeding wheel 5, and the second clamping plate 62 is arranged at an angle and relative to the end face of the seeding wheel 5.

[0049] In this embodiment, when the seeding wheel 5 rotates, the seeding trough 51 located on the horizontal line of the seeding wheel 5 is limited by the first clamping plate 61, and the seeds will not fall out of the seeding trough 51. When the seeding trough 51 rotates below the horizontal line, the seeding trough 51 is released from the limitation of the first clamping plate 61 and slides down the second clamping plate 62 into the paddy field for sowing.

[0050] Example 5:

[0051] The basic content is the same as Example 2, except that:

[0052] See Figure 8 One end of the positioning rod 8 is connected to a universal joint 81, and the left and right sides of the positioning rod 8 are connected to clamping plates 82. The universal joint 81 is connected to the upper side of the support plate 12, and the two clamping plates 82 are symmetrically arranged on the upper side of the support plate 12.

[0053] Two mounting plates 19 are vertically connected to the support plate 12. The indicator rod 7 is inserted between the two mounting plates 19. A pin hole 191 is provided on the mounting plate 19. A positioning pin 192 is threaded into the pin hole 191 and threaded into the indicator rod 7.

[0054] In this embodiment, the positioning rod 8 can rotate 180 degrees through the universal joint 81 and the clamping plate 82. The mounting plate 19 can be connected to the support plate 12 by bolts. After connection, the indicator rod 7 is inserted between the two mounting plates 19, and the indicator rod 7 is fixed to the mounting plate 19 by screwing in the positioning pin 192.
