Description

Technical Field

[0001] This utility model relates to the field of mixed fertilizer production technology, and in particular to a mixing device for producing slow-mixed fertilizer for rice with strong stability. Background Technology

[0002] Rice slow-release fertilizer is a slow-release compound fertilizer specifically designed for rice cultivation.

[0003] The production of slow-mixed fertilizer for rice often requires a mixing device to complete the task of uniformly mixing various formulas and granular fertilizers. In the existing technology, the mixing device is mostly composed of a mixing cylinder and a drive device. The motor drives the rollers to rotate, and the rollers contact the rolling rings set on the outer wall of the mixing cylinder for transmission, so as to achieve the smooth rotation of the mixing cylinder. However, due to the different working and operating environments of the mixing devices, some devices installed outdoors are easily exposed to dust and impurities that can easily enter between the support rollers and the rolling rings, resulting in imperfect contact between the wheel surfaces and thus affecting the stable operation of the mixing drum and compromising its stability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device for the production of slow-mixed fertilizer for rice with high stability.

The protective housing includes a housing 1 and a housing 2 connected to each other. Both housing 1 and housing 2 have chip removal grooves at their bottoms. Brush bristles are installed in the middle of the chip removal grooves, and the brush bristles are in frictional contact with the rolling rings provided on the outer wall of the double cone cylinder. Multiple insertion holes are provided on both sides of the outer walls of the first and second shells. Insertion posts are inserted into the insertion holes. The insertion posts are installed on one side of the bristle ring. The bristle ring contacts the outer walls of the first and second shells respectively. A ring of bristles is installed on the inner ring of the bristle ring. The bristles are in contact with the outer wall of the double cone cylinder.

[0006] Furthermore, a preferred configuration is that the bottom of the chip removal groove is continuous.

[0007] In addition, in a preferred structure, drive shafts are rotatably mounted on both sides of the middle part of the frame via bearing seats, and a pair of drive rollers are mounted on the middle part of each drive shaft. The drive rollers are in extrusion contact with the rolling rings provided on the outer wall of the double cone cylinder.

[0008] Furthermore, in a preferred configuration, a feed inlet is connected to one side of the double-cone cylinder.

[0009] Furthermore, in a preferred configuration, a pair of rolling rings are symmetrically installed on both sides of the middle portion of the double-cone cylinder.

[0010] In addition, a preferred structure is that a plurality of inserts are installed on one side of the bristle ring, and a plurality of rubber rings are installed in the middle of the inserts. The outer diameter of the rubber rings is larger than the outer diameter of the inserts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-7 A mixing device for producing slow-mixed fertilizer for rice with high stability includes a frame 1, a double cone cylinder 12 installed in the middle of the frame 1, and drive rollers 22 connected to both sides of the double cone cylinder 12. The drive rollers 22 are driven to rotate by a drive motor 2, thereby realizing the rotation function of the double cone cylinder 12. A protective housing 3 is installed on the outside of the drive roller 22 and the double cone body 12; The protective housing 3 includes a housing 1 31 and a housing 2 32 connected to each other. Both housing 1 31 and housing 2 32 have chip removal grooves 5 at their bottoms. Brushes 51 are installed in the middle of the chip removal grooves 5, and the brushes 51 are in frictional contact with the rolling rings 13 provided on the outer wall of the double cone body 12. Multiple insertion holes 6 are provided on both sides of the outer wall of shell 1 31 and shell 2 32. Insertion pins 41 are inserted into the insertion holes 6. The insertion pins 41 are installed on one side of the bristle ring 4. The bristle ring 4 contacts the outer wall of shell 1 31 and shell 2 32 respectively. A ring of bristles 42 is installed on the inner ring of the bristle ring 4. The bristles 42 contact the outer wall of the double cone body 12.

[0017] The bottom of the chip discharge trough 5 is open to discharge the dust swept by the brush bristles 42. The dust is discharged directly to the outside. In this field, a trash can can be placed at the bottom of the chip discharge trough 5 to collect the dust. This is easy to understand and will not be explained further.

[0018] Both sides of the middle part of the frame 1 are rotatably mounted with drive shafts 21 via bearing seats. A pair of drive rollers 22 are mounted in the middle of each drive shaft 21. The drive rollers 22 are in contact with the rolling rings 13 provided on the outer wall of the double cone cylinder 12. The drive shaft 21 located on one side is driven by the drive motor 2 to achieve rotational movement.

[0019] A feed inlet 11 is connected to one side of the double cone cylinder 12.

[0020] A pair of rolling rings 13 are symmetrically installed on both sides of the middle part of the double cone cylinder 12.

[0021] Multiple insertion posts 41 are installed on one side of the bristle ring 4, and multiple rubber rings 411 are installed in the middle of the insertion posts 41. The outer diameter of the rubber rings 411 is larger than the outer diameter of the insertion posts 41. When the insertion posts 41 are connected to the insertion holes 6, the outer edge of the rubber rings 411 engages with the annular grooves 61 opened on the inner wall of the insertion holes 6.

[0022] In this embodiment, during the operation of the double cone cylinder 12, the bristles 42 provided inside the protective shell 3 rub against and slide against the surface of the double cone cylinder 12, and the bristle structure effectively blocks external dust from entering the shell.

[0023] The bristles 42 deform to a certain extent as the double cone cylinder 12 rotates, and the direction of deformation is the same as the direction of rotation of the double cone cylinder 12, and the bristles always adhere to the outer wall of the double cone cylinder 12. During the rotation of the double cone cylinder 12, the second bristle 42 ensures structural stability through the setting of the bristle ring 4. During this process, the second bristle 42 will not generate high-frequency vibration or large left and right sway, thus effectively blocking external dust on the outermost layer of the bristles.

[0024] Furthermore, with prolonged use, a large amount of dust accumulates on the brush bristles 42 until it becomes visible to the naked eye. At this point, the mixing equipment is stopped, and the brush bristle ring 4 is pulled outward to disengage the insert post 41 from the insertion hole 6, thereby completing the disassembly and maintenance of the brush bristle ring 4.

[0025] During the installation of the brush ring 4, the insertion post 41 is aligned and inserted into the insertion hole 6 on the housing 1 31 and housing 2 32. The rubber ring 411 on the outside of the insertion post 41 is pressed against the inner wall of the insertion hole 6 and engaged with the annular groove 61 opened on the inner wall of the insertion hole 6 to improve the stability of the insertion.

[0026] Brush bristles 51 are provided at the bottom of housing 1 31 and housing 2 32. Brush bristles 51 will make frictional contact with the roller ring 13 provided on the outer wall of the double cone body 12, and the front end of the brush bristles will always be attached to the roller ring 13. As the roller ring 13 rotates, brush bristles 51 will sweep away the dust attached to the roller ring 13 and allow some large particles of impurities to fall from the chip discharge groove 5.

[0027] There is a gap between each bristle.

[0028] The double cone cylinder 13 rotates through friction transmission via contact between the drive roller 22 and the rolling ring 13. The drive roller 22 and the rolling ring 13 are necessary technical structures and conventional configurations of existing mixing devices, and the specific transmission principle will not be explained further.

[0029] It should be noted that the structural wear of the bristle assembly (bristle 1 51, bristle 2 42) caused by friction is extremely low and can be ignored.

[0030] Both bristle 1 (51) and bristle 2 (42) contact the structural components with their front ends. Due to the softness of the bristles, they can always adhere to the structural surface to achieve stable contact. Furthermore, the contact between the bristles and the structural components has a negligible impact on the operating load of the equipment.

[0031] It should also be noted that during the rotation of the double cone cylinder 12, the bristle assembly (bristle one 51, bristle two 42) will deform accordingly. During this process, the rotation of the double cone cylinder 12 is smooth and relatively slow, and bristle one 51 and bristle two 42 can always adhere to the double cone cylinder 12 to achieve an effective dust removal effect. Similarly, if the brush is used to smoothly sweep the board surface in one direction, the bristles on the brush will not undergo a large displacement.

[0032] Moreover, bristles 2 42 have blocked most of the dust from entering the protective housing 3, so less dust can enter and be effectively handled by bristles 1 51.

[0033] It is worth noting that the fertilizer raw materials enter the double cone cylinder 12 through the feed inlet and are mixed as it rotates. The specific process is common knowledge in this field and will not be explained further.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
