Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer mixing devices, and in particular relates to a rice seedling raising fertilizer mixing device. Background Art

[0002] In the process of raising rice seedlings, applying fertilizers can provide the rice plants with the nutrients they need for growth and promote the survival and growth of the rice plants. In the prior art, fertilizers can improve soil properties and soil fertility levels, including nitrogen fertilizers, phosphorus fertilizers, potash fertilizers, nitrogen-phosphorus-potassium compound fertilizers, and biological organic fertilizers. In the process of raising seedlings and planting crops such as rice, it is sometimes necessary to mix several fertilizers in a certain proportion and spread them in the soil according to needs.

[0003] Prior art CN212348400U discloses a fertilizer stirring device for agricultural machinery, including a box body, a support frame for dragging the box body is fixedly installed at the bottom of the box body, a box door is hinged at the top of the box body, electric telescopic rods for driving the box door to rotate around the hinge are arranged at mutually symmetrical positions on both sides of the box body, the tops of the two electric telescopic rods are hinged to the box body, a stirring assembly is arranged inside the box body, and also includes a motor for driving the stirring assembly to stir the fertilizer, and a discharge port with a valve is opened at the bottom of the box body. Different types of fertilizers are poured into the box body, and the fertilizers are stirred by the stirring assembly. The box door is closed to prevent the fertilizers from splashing on the body. When the stirring is completed, the discharge port is opened to release the stirred fertilizers. It is undeniable that the agricultural machinery fertilizer stirring device disclosed in the patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: referring to its specification and drawings, it uses the discharge port arranged at the bottom of the box to discharge the evenly stirred fertilizer, but in actual unloading, the material close to the discharge port is easy to discharge, while the material at a distance from the discharge port is difficult to discharge through the discharge port, which makes the agricultural machinery fertilizer stirring device disclosed in the patent have certain inconveniences when unloading; secondly, the stirring blades are inclined. Although the inclined stirring blades can also stir the materials in the box, for the materials at the bottom of the box, the stirring blades only push the materials to one side and cannot flip the materials at the bottom upwards, which may to a certain extent cause the fertilizer to not be thoroughly mixed.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example

[0038] See attached Figure 1-6 , a rice seedling raising and fertilizer mixing device, comprising:

[0039] Fertilizer mixing rack 1;

[0040] A fertilizer mixing chamber 2 is located in the middle of the fertilizer mixing frame 1, and a fixing cylinder 21 is fixed to each end of the fertilizer mixing chamber 2 by bolts; in this embodiment, the cross-section of the fertilizer mixing chamber 2 is semicircular at the bottom and rectangular at the top; a cover plate 22 is provided at the top opening of the fertilizer mixing chamber 2, and one side of the cover plate 22 is hinged to the top of the fertilizer mixing chamber 2 by hinges;

[0041] The stirring member 3 comprises two connecting disks 31 symmetrically arranged in the fertilizer mixing chamber 2, a plurality of stirring plates 32 uniformly arranged between the two connecting disks 31 along the circumference of the connecting disks 31 and fixedly connected to the connecting disks 31 at corresponding positions at both ends, a transmission cylinder 33 fixed to the middle part of the outer side of the connecting disk 31, a first driven pulley 34 fixed to the outer end of one of the transmission cylinders 33, a first driving motor 35, and a first driving pulley 37 fixed to the output shaft of the first driving motor 35 and connected to the first driven pulley 34 through a first driving belt 36; wherein, the outer side of the connecting disk 31 is in contact with the inner wall at both ends of the fertilizer mixing chamber 2; the outer end of the transmission cylinder 33 penetrates the fertilizer mixing chamber 2 and the fixed cylinder 21 and is rotatably connected to the fertilizer mixing chamber 2 and the fixed cylinder 21; a first seat bearing 38 is rotatably connected to the position of the transmission cylinder 33 near the end, and the first seat bearing 38 is fixed to the fertilizer mixing frame 1; the outer side of the stirring plate 32 is in contact with the inner wall at the bottom of the fertilizer mixing chamber 2, and the stirring plate 32 is located in the radial direction of the connecting disk 31;

[0042] The unloading member 4 is transmission-connected to the fixed cylinder 21 and drives the fixed cylinder 21 to rotate. Specifically, the unloading member 4 includes a driven gear 41 integrally formed at the outer end of the fixed cylinder 21, a unloading driving motor 42 fixed on the fertilizer mixing frame 1, and a driving gear 43 fixed on the output shaft of the unloading driving motor 42 and meshing with the driven gear 41;

[0043] The auger member 5 is provided in the fertilizer mixing chamber 2 and has a transmission shaft 51 with both ends passing through the fertilizer mixing chamber 2 and the transmission cylinder 33, and an auger blade 52 fixed on the transmission shaft 51 and located in the fertilizer mixing chamber 2, a second driven pulley 53 fixed on the transmission shaft 51 away from the first driven pulley 34, a second drive motor 54, and a second drive pulley 56 fixed on the output shaft of the second drive motor 54 and connected to the second driven pulley 53 through a second transmission belt 55; wherein, the end of the transmission shaft 51 is rotatably connected with a second seat bearing 57, and the second seat bearing 57 is fixed on the fertilizer mixing frame 1; the second driven pulley 53 is located on the inner side of the second seat bearing 57; a distance is left between the outer side of the auger blade 52 and the inner side of the stirring plate 32;

[0044] In this embodiment, a clearance opening (not marked in the drawings) corresponding to the fertilizer mixing chamber 2 is reserved at the front side of the fertilizer mixing rack 1 .

[0045] It should be noted that, in this embodiment, the first drive motor 35, the unloading drive motor 42, and the second drive motor 54 are all connected to an external power supply and controlled by an external switch; the central axes of the fixed cylinder 21, the transmission cylinder 33, the driven gear 41 and the transmission shaft 51 coincide.

[0046] When in use, the fertilizer to be mixed is added into the fertilizer mixing chamber 2 from the top opening of the fertilizer mixing chamber 2 in a suitable proportion, and the cover plate 22 is closed. Then the first driving motor 35 is started, the first driving motor 35 drives the first driving pulley 37 to rotate, the first driving pulley 37 drives the first driven pulley 34 to rotate through the first transmission belt 36, the first driven pulley 34 drives the transmission cylinder 33 to rotate, the transmission cylinder 33 drives the connecting disk 31 to rotate, the connecting disk 31 drives the multiple stirring plates 32 to rotate, and thus the first driving motor 35 drives the multiple stirring plates 32 to rotate through a series of transmissions, and the stirring plates 32 stir the materials in the fertilizer mixing chamber 2 when they rotate. Since the outer side of the stirring plate 32 is in contact with the inner wall of the bottom of the fertilizer mixing chamber 2, when the stirring plate 32 rotates upward from the bottom of the fertilizer mixing chamber 2, the stirring plate 32 will push the material at the bottom of the fertilizer mixing chamber 2 to move outward and drive part of the material to move upward. After the part of the material moves a certain distance upward with the stirring plate 32, the material falls from the stirring plate 32, so that the material at the bottom of the fertilizer mixing chamber 2 can be pushed outward and lifted up, which can improve the effect of material mixing.

[0047] In addition, during the rotation of the first drive motor 35, the second drive motor 54 is started to rotate forward, the second drive motor 54 drives the second drive pulley 56 to rotate, the second drive pulley 56 drives the second driven pulley 53 to rotate through the second transmission belt 55, the second driven pulley 53 drives the transmission shaft 51 to transmit, the transmission shaft 51 drives the auger blade 52 to rotate, and thus the second drive motor 54 drives the auger blade 52 to rotate through a series of transmissions. When the auger blade 52 rotates, part of the material can be pushed to move along the axial direction of the transmission shaft 51; similarly, after the second drive motor 54 rotates forward for a certain period of time, the second drive motor 54 is controlled to rotate in the reverse direction. In this way, through the forward and reverse rotations of the second drive motor 54, part of the material can be pushed to move repeatedly along the axial direction of the transmission shaft 51, which can assist the stirring element 3 in improving the material stirring and mixing efficiency and effect.

[0048] After the material is stirred and mixed, the first drive motor 35 and the second drive motor 54 are turned off, and the unloading drive motor 42 is started to rotate forward, the unloading drive motor 42 drives the drive gear 43 to rotate, the drive gear 43 drives the driven gear 41 to rotate, the drive gear 43 drives the fixed cylinder 21 to rotate, and the fixed cylinder 21 drives the fertilizer mixing chamber 2 to rotate. In this way, the unloading drive motor 42 rotates and the fertilizer mixing chamber 2 rotates through a series of transmissions. When the fertilizer mixing chamber 2 rotates a certain angle, the cover plate 22 is opened, and the evenly mixed materials will flow out from the opening at the top of the fertilizer mixing chamber 2 to achieve unloading. After unloading is completed, the unloading drive motor 42 is controlled to rotate in the reverse direction to restore the fertilizer mixing chamber 2 to its initial position.

[0049] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
