The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0029] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0030] The utility model discloses a double-trough rice seedling raising device, comprising two seedling raising boxes, which are referred to as a front seedling raising box 1 and a rear seedling raising box 2 for the convenience of description. The front seedling raising box 1 and the rear seedling raising box 2 have the same structure, are fixedly mounted together and arranged front to back, and the interiors of the front seedling raising box 1 and the rear seedling raising box 2 are hollow, and a feed inlet 3 is provided at the upper end for placing subsoil or rice seeds or floating soil, and a discharge outlet 4 is provided at the lower end for sowing subsoil or rice seeds or floating soil. The lower ends of the front seedling raising box 1 and the rear seedling raising box 2 are inclined funnel-shaped, and the feed inlet 3 is larger than the discharge outlet 4. Mounting plates 5 are fixed on both sides of the front seedling raising box 1 and the rear seedling raising box 2 for providing a mounting foundation, and a driving shaft 6 is rotatably mounted between the two mounting plates 5. Both ends of the driving shaft 6 pass through the mounting plates 5 and are fixedly mounted with walking wheels 7. The walking wheels 7 are mainly used for walking on an existing track, and the walking wheels 7 on one side are coaxially connected with a wheel 7 which is placed inside and fixedly sleeved on the driving shaft. The driving gear 8 on 6 is meshed with a switching mechanism beside the driving gear 8. The switching mechanism includes two switching gears 9. The two switching gears 9 are placed on both sides of the driving gear 8. The two switching gears 9 are meshed with the driving gear 8, but not at the same time. A sowing mechanism is also meshed on the outside of the switching gear 9. The sowing mechanism is arranged at the discharge port 4 and is used to control the unloading of the discharge port 3 of the front seedling box 1 and the rear seedling box 2, which is equivalent to the unloading switch of the discharge port 4. A sleeve 10 is connected to the side wall direction of the switching gear 9 so that when the sleeve 10 does not rotate, the switching gear 9 can rotate, but when the sleeve slides 10, the switching gear 9 can be driven to slide together. A sleeve shaft 11 is arranged above the sleeve 10, and a crank handle 12 that can swing left and right is arranged above the driving shaft 6. The crank handle 12 is tilted, and push rods 13 are hinged at both ends of the crank handle 12, and the other end of the push rod 13 is hinged to the sleeve shaft 11.

[0031] Turn the crank 12, the crank 12 drives the push rod 13 to rotate, the push rod 13 drives the sleeve 10 to slide, and the sleeve 10 drives the switching gear 9 to slide together. When the crank 12 is rotated, the switching gear 9 at one end is meshed with the driving gear 8, and the switching gear 9 at the other end is disengaged from the driving gear 8. When the walking wheel 7 walks on the track, the walking wheel 7 rotates, driving the driving gear 8 to rotate synchronously, and the driving gear 8 engages with the above-mentioned switched switching gear 9 to rotate, and the switching gear 9 engages with the sowing mechanism on the side to open and start sowing.

[0032] Furthermore, a symmetrically arranged switching shaft 14 is fixedly installed on the inner side of the mounting plate 5, and the switching gear 9 is rotatably and slidably installed on the switching shaft 14. A rotating ring 15 is fixed on the outer inner wall of the switching gear 9, and a limiting ring is fixed at the end of the rotating ring 15. The rotating ring 15 is rotatably installed in the sleeve 10. The sleeve 10 is provided with a rotating groove with a T-shaped cross-section corresponding to the rotating ring 15 and the limiting ring. The rotating ring 15 and the limiting ring are rotatably installed in the rotating groove, so that the switching gear 9 can not only rotate in the sleeve 10, but also drive the switching gear 9 to slide synchronously when the sleeve 10 slides. In order to better realize the sliding of the sleeve 10, a sliding block 16 is integrally fixed to the outer side of the sleeve 10, and the sleeve 10 and the sliding block 16 are integrally slidably sleeved on the switching shaft 14.

[0033] Furthermore, the sowing mechanism includes a sowing roller 17 and a roller brush roller 18 rotatably mounted at the discharge port 4, the roller brush roller 18 is partially placed in the discharge port 4, and one end of the sowing roller 17 and the roller brush roller 18 are respectively fixedly sleeved with a sowing gear 19 and a roller brush gear 20 that mesh with each other, and the sowing gear 19 meshes with the switching gear 9 on the side. The sowing mechanism relies on the rotation of the sowing roller 17 and the roller brush roller 18, so that the roller brush moves the internal subsoil or rice seeds or floating soil to discharge the material, and when the sowing roller 17 and the roller brush roller 18 do not rotate, the discharge port 4 does not discharge the material.

[0034] Alternatively, only the end of the roller brush roller 18 may be provided with a roller brush gear 20, and the end of the sowing roller 17 may not be provided with a sowing gear 19. In this case, the roller brush gear 20 is meshed with the switching gear 9, that is, the sowing roller 17 and the roller brush roller 18 are interchanged in position.

[0035] In addition to this embodiment, the existing sowing mechanism of the existing rice device can also be used. Since there are many sowing mechanisms, the sowing mechanism conventionally known to those skilled in the art can also be used, without being limited to this sowing mechanism.

[0036] The sowing mechanism can also be equipped with an adjustment mechanism for adjusting the size of the discharge port 4. Since it is not the main improvement point of the present application, the adjustment mechanism of the existing rice seedling raising device can be used. For example, transverse adjustment grooves are provided above and below the roller brush roller 20, and the mounting hole of the roller brush roller 18 is a transverse adjustment groove. An adjustment plate is fixed on the roller brush gear 20, and the size of the discharge port 4 is adjusted by moving the adjustment plate in the transverse position of the adjustment groove.

[0037] Furthermore, a support plate 21 is fixed between the mounting plate 5 and the front seedling box 1 and the rear seedling box 2, and the crank handle 12 is rotatably mounted on the support plate 21 via a crank handle shaft, and a hand wheel 22 is coaxially fixed to the upper end of the crank handle shaft, so that when the hand wheel 22 is rotated, the crank handle 12 rotates around the support plate 21, thereby driving the above-mentioned push rod 13 to rotate, and the sleeve 10 and the switching gear 9 slide on the switching shaft 14 for switching.

[0038] Furthermore, an operating opening 23 is provided on the mounting plate 5 to facilitate operation of the crank 12 or the hand wheel 22 .

[0039] Furthermore, filter screens 24 are placed in the front seedling raising box 1 and the rear seedling raising box 2, which are mainly used to filter the subsoil or the floating soil so that there are no large pieces of the spread subsoil or the floating soil.

[0040] Furthermore, box side panels 25 are symmetrically installed at the front end of the front seedling box 1 or the rear seedling box 2, a front sleeve 26 is fixed on the inner side of the box side panel 25, a connecting rod 27 is rotatably installed in the sleeve 10, and a handrail 28 is fixed in the middle of the connecting rod 27 for convenient handheld pushing operation.

[0041] Furthermore, multiple fixing columns 29 are fixed on both sides of the front seedling box 1 and the rear seedling box 2, and the multiple fixing columns 29 fix the same mounting plate 5, thereby fixing the front seedling box 1 and the rear seedling box 2 together. The front seedling box 1 and the rear seedling box 2 are also fixed via multiple fixing rods 30.

[0042] Working principle:

[0043] The soil before planting rice seeds is called subsoil, and the soil after planting rice seeds is called floating soil. The subsoil and floating soil used are the same, but the subsoil will be thicker than the floating soil when sowing.

[0044] Place the guide rail on the seedling bed, place the filter screen plate 24 in the front seedling box 1, put soil in the front seedling box 1, put rice seeds in the rear seedling box 2, then hold the handrail 28 to push the front seedling box 1 and the rear seedling box 2 to walk on the track, and the walking wheel 7 drives the driving gear 8 to rotate when moving, and the driving gear 8 engages the switching gear 9 on the front side, and the switching gear 9 engages the sowing roller 17 and the roller brush roller 18 of the front seedling box 1 to rotate, or only engages the roller brush roller 18 to rotate (only the roller brush roller 18, no sowing roller 17), the roller brush roller 18 is moved to spread the soil in the front seedling box 1, and the rear seedling box 2 is moved. Since the roller brush 18 of the seedling box 2 is not engaged, it does not rotate and does not unload. When the bottom soil is sown, the hand wheel 22 is driven by the operating port 23. The hand wheel 22 drives the crank 12 to rotate via the crank shaft, and the crank 12 drives the push rod 13 to rotate. The push rod 13 drives the sleeve 10 to slide on the switching shaft 14. The sleeve 10 disengages the front switching gear 9 and engages the rear switching gear 9. Similarly, at this time, the front seedling box 1 no longer unloads, and the rear seedling box 2 starts to sow rice seeds. When the rice seeds are pushed, the hand wheel 22 is rotated in the reverse direction to switch to the front seedling box 1 for unloading and floating soil sowing.

[0045] The utility model provides a double-slot design of a front seedling box and a rear seedling box, and then cooperates with a switching mechanism to achieve the goal of first sowing subsoil with the front seedling box, then switching to the rear seedling box to plant rice seeds, and then switching to the front seedling box to sow floating soil. After the track is placed, the seedlings can be raised on the current seedling bed at one time, and there is no need to move the track and the seedling device back and forth three times to sow subsoil, rice seeds, and floating soil respectively, which saves time, reduces the labor intensity of staff carrying, and improves the efficiency of seedling sowing.

[0046] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the utility model. After reading the above content, various modifications and substitutions of the utility model will be obvious to those skilled in the art. Therefore, the protection scope of the utility model should be limited by the attached claims.
