[0002] In the field of cold-region rice cultivation, with the rapid development of smart agriculture, improving the automation and intelligence level of rice seedling cultivation has become the key to improving rice yield and quality. Although the traditional cold-region rice seedling cultivation device has realized the automatic sowing of seedling trays in the greenhouse, it is still highly dependent on manual operation in terms of movement and positioning of the device, which is obviously inconsistent with the development trend of smart agriculture.

[0003] The cold-region rice seedling raising device in the prior art needs to be manually pushed to move between rows during sowing operations, and relies on the operator's hand to keep the device stable to prevent deviation. At the same time, after each movement, the operator needs to visually determine whether the device is accurately aligned with the next row of seedling trays. This process is not only labor-intensive, but also has limited accuracy, and it is difficult to meet the requirements of modern smart agriculture for precise operations. The method of visually judging whether the seedling raising device has moved into place also increases the time for comparison and adjustment, thereby affecting the overall work efficiency.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1, reference Figure 1 to Figure 19, which is the first embodiment of the present invention, and this embodiment provides a device for raising rice seedlings in cold regions. The device for raising rice seedlings in cold regions includes a main body component 100, including a seeder 101, a rotating shaft 102 and a moving wheel 103. The rotating shaft 102 is rotatably connected to the seeder 101, and the moving wheel 103 is fixed to the surface of the rotating shaft 102.

[0040] A power mechanism is provided in the seeder 101, which can drive the rotating shaft 102 to rotate, so that the rotating shaft 102 drives the moving wheel 103 to rotate, and the two rotating shafts 102 are connected by a belt, so that the four moving wheels 103 can rotate at the same time, thereby driving the seeder 101 to move. The seeder 101 is a prior art. The movement and sowing of the seeder 101 are both remotely controlled. When the seeder 101 moves above the seedling tray, the seeder 101 can be remotely controlled to start sowing on the seedling tray. When the sowing is completed, the seeder 101 can be controlled to reset.

[0041] The support assembly 200 is arranged below the seed drill 101, and includes a support rail 201a arranged on the ground, a support wheel 201b rolling on the top of the support rail 201a, a support foot 201c arranged on the surface of the support wheel 201b, a support frame 201d fixed on the top of the support foot 201c, a rotating rod 201e rotatably connected inside the support foot 201c, the support wheel 201b is fixed to the surface of the rotating rod 201e, a fixed rod 201f is fixed on one side of the support frame 201d, a lifting sleeve 201g slides on the surface of the fixed rod 201f, a first spring 201h is arranged in the lifting sleeve 201g, and the other end of the first spring 201h is fixed to the inner wall of the fixed rod 201f, a flat plate 201i is fixed at the bottom of the lifting sleeve 201g, a scraper bar 201j is fixed at the bottom of the flat plate 201i, and the scraper bar 201j is located at the top of the support rail 201a.

[0042] The support frame 201d can move on the top of the support rail 201a through the support of the support foot 201c, the support wheel 201b and the rotating rod 201e. The support rail 201a is laid on the ground of the greenhouse, so that the support frame 201d can drive the seeder 101 to move. The fixed rod 201f is used to position the lifting sleeve 201g. The first spring 201h is in a compressed state. Through the reset elastic force of the first spring 201h, the lifting sleeve 201g can be pressed against the flat plate 201i, so that the flat plate 201i presses the scraper 201j, so that the scraper 201j can scrape off the soil that may be attached to the top of the support rail 201a, and prevent the soil on the top of the support rail 201a from adhering to the support wheel 201b. The support wheel 201b can be provided with a tooth groove, and the support rail 201a can be provided with teeth to prevent the support wheel 201b from slipping on the top of the support rail 201a.

[0043] Specifically, the support assembly 200 also includes a support member 202, which is arranged on the top of the support frame 201d, including a hinge block 202a fixed to the top of the support frame 201d, a hinge plate 202b is hinged in the hinge block 202a, a cross beam 202c is fixed on the top of the hinge plate 202b, a support beam 202d is fixed between the two cross beams 202c, a support seat 202e is fixed on the top of the support frame 201d, the support beam 202d is located on the top of the support seat 202e, a stop plate 202f is fixed on the top of the support beam 202d, and the seeder 101 is located on one side of the stop plate 202f.

[0044] The hinge block 202a is used to support the hinge plate 202b so that the beam 202c can swing, the support beam 202d is used to connect the two beams 202c, the moving wheel 103 rolls on the top of the beam 202c, and the support seat 202e is used to support the support beam 202d, so that the beam 202c can provide sufficient supporting force for the planter 101. When the planter 101 moves to the side of the stop plate 202f, the planter 101 can be remotely controlled to stop moving.

[0045] Optionally, two sensors are provided on the beam 202c. When the seeder 101 passes the first sensor, it can automatically start sowing. When the seeder 101 passes the second sensor, it automatically stops sowing, thereby improving the intelligence of the device. The above-mentioned method of controlling the start and stop of the sowing mechanism of the seeder 101 by sensors is a prior art, and those skilled in the art should be clearly aware of it and will not be elaborated here.

[0046] Specifically, the support member 202 also includes a sliding rod 202g that slides in another support beam 202d, a support plate 202h is fixed to the bottom of the sliding rod 202g, a support disk 202i is fixed to the other end of the sliding rod 202g, a second spring 202j is sleeved on the surface of the sliding rod 202g, a threaded column 202k is fixed to the top of the support plate 202h, and an adjusting nut 202l is connected to the surface of the threaded column 202k through threaded rotation.

[0047] There are two slide bars 202g, which are used to support the support plate 202h, so that when the support plate 202h falls on the ground, it can provide support for the support beam 202d. The support plate 202i is used to limit the second spring 202j. The second spring 202j is in a compressed state and is used to push the support plate 202i, so that the support plate 202i drives the support plate 202h to move upward through the slide bar 202g. By rotating the adjusting nut 202l, the distance between the support beam 202d and the support plate 202h can be adjusted.

[0048] When the seeder 101 is located at the beam 202c above the top of the support frame 201d, the support beam 202d can fall on the top of the support seat 202e under the action of its own gravity. At this time, the support plate 202h is far away from the ground, so when the support frame 201d drives the seeder 101 to move, no friction will be generated between the support plate 202h and the ground.

[0049] When the seeder 101 moves from the beam 202c above the top of the support frame 201d toward the support plate 202h, the beam 202c can be pressed down by the gravity of the seeder 101 itself, so that the support plate 202h falls to the ground, thereby supporting the beam 202c above the support plate 202h.

[0050] Specifically, the support assembly 200 also includes a transmission member 203, which is arranged on the support frame 201d, including a first bevel gear 203a fixed to the surface of the rotating rod 201e, a fixed plate 203b is fixed to one side of the support frame 201d, a rotating column 203c is rotatably connected inside the fixed plate 203b, a second bevel gear 203d is fixed to the surface of the rotating column 203c, the second bevel gear 203d is meshed with the first bevel gear 203a, and a rotating gear 203e is fixed to the surface of the rotating column 203c.

[0051] When the support wheel 201b starts to move on the top of the support rail 201a, it can drive the rotating rod 201e to rotate, so that the rotating rod 201e drives the first bevel gear 203a to rotate, and the first bevel gear 203a drives the second bevel gear 203d to rotate, so that the second bevel gear 203d drives the rotating gear 203e to rotate.

[0052] Specifically, the transmission member 203 also includes a support shell 203f fixed to the bottom of the support frame 201d, and a first rotating shaft 203g is rotatably connected in the support shell 203f, and a first gear 203h and a second gear 203i are fixed on the surface of the first rotating shaft 203g. A second rotating shaft 203j is also rotatably connected in the support shell 203f, and a third gear 203k is fixed on the surface of the second rotating shaft 203j.

[0053] The first gear 203h is meshed with the rotating gear 203e, and the second gear 203i is meshed with the third gear 203k. The radius of the second gear 203i is much smaller than that of the first gear 203h, so that the transmission of the first gear 203h and the second gear 203i forms a deceleration effect, thereby driving the third gear 203k to rotate.

[0054] Example 2, reference Figure 1 to Figure 19 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0055] Specifically, the support assembly 200 also includes an adjusting member 204, which is arranged on the support frame 201d, including a first positioning seat 204a fixed on the top of the support frame 201d, an adjusting shaft 204b is rotatably connected inside the first positioning seat 204a, a pulley 204c is fixed on the surface of the adjusting shaft 204b, two pulleys 204c are arranged on the surface of the second rotating shaft 203j, a positioning plate 204d is fixed on the surface of the second rotating shaft 203j, a third spring 204e is fixed on one side of the positioning plate 204d, the other end of the third spring 204e is fixed to one side of the pulley 204c, and a transmission belt 204f is arranged on the pulley 204c on the surface of the adjusting shaft 204b and the second rotating shaft 203j.

[0056] The first positioning seat 204a is used to support the adjustment shaft 204b. The surface of the adjustment shaft 204b has two pulleys 204c arranged opposite to each other. The pulley 204c close to the first positioning seat 204a slides on the surface of the adjustment shaft 204b and does not rotate relative to the adjustment shaft 204b. The other pulley 204c is fixed to the surface of the adjustment shaft 204b. The two pulleys 204c on the surface of the second rotating shaft 203j are arranged opposite to each other, and the pulley 204c close to the third gear 203k is fixed to the second rotating shaft 203j. The third spring 204e is in a compressed state and is used to push the positioning plate 204d, so that the two pulleys 204c on the second shaft 203j are close to each other. Through the connection of the transmission belt 204f, the second shaft 203j can drive the adjusting shaft 204b to rotate through the pulley 204c and the transmission belt 204f.

[0057] By pushing the pulley 204c sliding on the surface of the adjusting shaft 204b, the two pulleys 204c on the surface of the adjusting shaft 204b can squeeze the transmission belt 204f, so that the transmission belt 204f moves toward the edge of the pulley 204c. Since the length of the transmission belt 204f is fixed, when the transmission belt 204f moves toward the edge of the two pulleys 204c on the surface of the adjusting shaft 204b, the transmission belt 204f can squeeze the two pulleys 204c on the surface of the second rotating shaft 203j, so that the two pulleys 204c move away from each other, thereby reducing the transmission radius of the transmission belt 204f at the second rotating shaft 203j and increasing the transmission radius of the transmission belt 204f at the adjusting shaft 204b, thereby changing the transmission ratio of the adjusting shaft 204b and the second rotating shaft 203j.

[0058] Specifically, the adjusting member 204 also includes a second positioning seat 204g fixed on one side of the supporting frame 201d, an adjusting column 204h is slidably arranged inside the second positioning seat 204g, the surface of the adjusting column 204h is rotatably connected to the adjusting wheel 204i through a thread, an extrusion bolt 204j is threadedly connected to the inner thread of the second positioning seat 204g, a push rod 204k is slidably arranged inside the first positioning seat 204a, a connecting disk 204l is fixed to the end of the push rod 204k, the connecting disk 204l is fixed to the end of the adjusting column 204h, a connecting sleeve 204m is fixed to the other end of the push rod 204k, and the surface of the connecting sleeve 204m is rotatably connected to the extrusion sleeve 204n through a bearing.

[0059] The second positioning seat 204g is used to support the adjusting column 204h, and the second positioning seat 204g can limit the adjusting wheel 204i, and the adjusting wheel 204i is squeezed by the squeezing bolt 204j to fix the adjusting wheel 204i. By rotating the adjusting wheel 204i, the adjusting column 204h can be driven to move in the second positioning seat 204g, so that the adjusting column 204h pushes the connecting disk 204l, so that the connecting disk 204l pushes the connecting sleeve 204m through the push rod 204k, so that the connecting sleeve 204m squeezes the movable pulley 204c on the surface of the adjusting shaft 204b through the squeezing sleeve 204n, thereby changing the distance between the two pulleys 204c, thereby changing the transmission radius of the transmission belt 204f at the adjusting shaft 204b.

[0060] Specifically, the support assembly 200 also includes a locking member 205, which is arranged on the support frame 201d, and includes a positioning plate 205a fixed to the surface of the support frame 201d, and a transmission rod 205b is rotatably connected inside the positioning plate 205a, and a third bevel gear 205c is fixed to the surface of the transmission rod 205b. The third bevel gear 205c is also fixed to the surface of the adjustment shaft 204b. The two third bevel gears 205c are meshed, and a locking plate 205d is fixed to the surface of the transmission rod 205b, and a locking block 205e is fixed to one side of the locking plate 205d.

[0061] The positioning plate 205a is used to support the transmission rod 205b. The adjusting shaft 204b drives the transmission rod 205b to rotate through the third bevel gear 205c, so that the transmission rod 205b drives the locking plate 205d to rotate. When the locking plate 205d rotates, it can drive the locking block 205e on its surface to move in a circle. By limiting the locking block 205e, the locking plate 205d can be limited, thereby limiting the support wheel 201b, so that the support frame 201d stops at the top of the support rail 201a.

[0062] Specifically, the support assembly 200 further includes a positioning member 206, which is disposed on the support frame 201d, and includes a fixed shell 206a fixed to the top of the support frame 201d, a movable seat 206b slidingly disposed in the fixed shell 206a, a slide plate 206c slidingly disposed in the movable seat 206b, a stopper 206d fixed to one side of the slide plate 206c, a fourth spring 206e fixed to one side of the slide plate 206c, the other end of the fourth spring 206e fixed to the inner wall of the movable seat 206b, and the fixed shell 206a. A fifth spring 206f is fixed to the inner wall of 06a, and the other end of the fifth spring 206f is fixed to the inner wall of the moving seat 206b. A clamping block 206g is slidable in the moving seat 206b, and a sixth spring 206h is arranged in the clamping block 206g, and the other end of the sixth spring 206h is fixed to the inner wall of the moving seat 206b. An extrusion strip 206i is fixed to the inner wall of the moving seat 206b, a pull plate 206j is slidable in the moving seat 206b, and a driving block 206k is fixed to one side of the pull plate 206j.

[0063] The fixed shell 206a is used to support the movable seat 206b. A limit bar is set between the fixed shell 206a and the movable seat 206b, so that the movable seat 206b can slide stably in the fixed shell 206a without falling. A limit bar is set between the slide plate 206c and the movable seat 206b, so that the slide plate 206c can slide stably. The fourth spring 206e is in a stretched state and is used to pull the slide plate 206c. The stopper 206d is used to limit the locking block 205e, so that the locking block 205e cannot continue to move, thereby limiting the locking plate 205d. There are two locking blocks 205e, which are respectively located on both sides of the stopper 206d in the figure.

[0064] The fifth spring 206f is in a compressed state, and is used to push the movable seat 206b so that the movable seat 206b approaches the locking plate 205d, so that the block 206d can be stuck between the two locking blocks 205e. The sixth spring 206h is in a compressed state, and is used to push the card block 206g, so that the driving block 206k can be stuck on one side of the card block 206g. The driving block 206k is pulled by the pull plate 206j, so that the card block 206g drives the movable seat 206b away from the locking plate 205d, thereby making the block 206d away from the two locking blocks 205e. At this time, under the pulling of the fourth spring 206e, the slide plate 206c drives the block 206d to move to the side of the larger locking block 205e, thereby releasing the fixation of the locking plate 205d.

[0065] As the pull plate 206j moves, the block 206g will hit the end of the extrusion strip 206i, so that the extrusion strip 206i squeezes the block 206g, thereby compressing the sixth spring 206h, causing the block 206g to shrink into the moving seat 206b, thereby separating the driving block 206k and the block 206g. At this time, under the elastic force of the fifth spring 206f, the moving seat 206b can drive the block 206d to move to the side close to the larger locking block 205e.

[0066] Specifically, the positioning member 206 also includes a vertical plate 2061 fixed to the top of the support frame 201d, a support column 206m is fixed to one side of the vertical plate 2061, a detection plate 206n slides on the surface of the support column 206m, and a seventh spring 206o is sleeved on the surface of the support column 206m.

[0067] The vertical plate 206l is used to support the support column 206m, so that the support column 206m supports the detection plate 206n, so that the detection plate 206n can slide stably on the surfaces of the two support columns 206m. The seventh spring 206o is in a compressed state and is used to push the detection plate 206n. The pull plate 206j is fixed on one side of the detection plate 206n.

[0068] When the seed drill 101 performs a reset movement, the detection plate 206n may be squeezed, so that the detection plate 206n drives the pulling plate 206j to move, thereby causing the pulling plate 206j to pull the driving block 206k.

[0069] During use, when it is necessary to sow seeds on the seedling tray under the crossbeam 202c, first rotate the extrusion bolt 204j to release the limit on the adjusting wheel 204i. At this time, rotate the adjusting wheel 204i. When the adjusting locking plate 205d rotates one circle, the supporting wheel 201b moves a suitable distance on the supporting rail 201a, and then the extrusion bolt 204j fixes the adjusting wheel 204i.

[0070] At this time, start the seeder 101, so that the seeder 101 moves from the beam 202c above the top of the support frame 201d to the support plate 202h. Under the action of its own gravity, the beam 202c can be pressed down, so that the support plate 202h falls to the ground, thereby supporting the beam 202c above the support plate 202h. During this process, the seeder 101 will sow seeds on the seedling tray below.

[0071] When the seeder 101 is reset, the beam 202c above the support frame 201d can be pressed down by the gravity of the seeder 101 itself, so that the support beam 202d falls on the top of the support seat 202e. At this time, the support plate 202h is far away from the ground, so that when the support frame 201d drives the seeder 101 to move, no friction will be generated between the support plate 202h and the ground.

[0072] When the seeder 101 moves to the side of the stop plate 202f, the detection plate 206n can be squeezed, so that the detection plate 206n drives the pull plate 206j to move, so that the pull plate 206j pulls the driving block 206k, so that the driving block 206k can be clamped on the side of the clamping block 206g, and the driving block 206k is pulled by the pull plate 206j, so that the clamping block 206g drives the moving seat 206b away from the locking plate 205d, so that the block 206d is away from the two locking blocks 205e. At this time, under the pull of the fourth spring 206e, the slide plate 206c drives the block 206d to move to the side of the larger locking block 205e, thereby releasing the fixation of the locking plate 205d, so that the support wheel 201b can move on the top of the support rail 201a, so that the support frame 201d drives the seeder 101 to move.

[0073] When the support frame 201d moves, the support wheel 201b can drive the locking plate 205d to rotate through the transmission member 203 and the adjustment member 204. When the locking plate 205d rotates one circle, the block 206d can be stuck between the two locking blocks 205e to position the locking plate 205d. During this process, the support wheel 201b moves a fixed distance on the top of the support rail 201a, so that the sowing accuracy of the seeder 101 is higher, and there is no need for manual visual comparison every time, thereby improving the sowing efficiency.

[0074] When the seed drill 101 is sowing, the locking plate 205d is in a locked state, so that the crossbeam 202c will not deviate, thereby improving the stability of the cold-region rice seedling raising device.
