Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid material stirring equipment, in particular to a stirring shaft mechanism with adjustable height. Background Art
[0002] In modern animal husbandry, feed mixing equipment is one of the key facilities to ensure balanced animal nutrition and improve feeding efficiency. Especially for the traditional liquid feed mixing system of pig farms, its design needs to take into account the feeding needs of pigs at different growth stages to achieve the best feeding effect. However, the stirring shaft and the spoiler set on the stirring shaft in the commonly used liquid feed mixing equipment are fixed, which is usually only suitable for the feeding needs of pigs in ordinary fattening houses; while for the integrated nursery and fattening houses, the feeding environment and needs of the pigs are more complex; especially in the early stage of nursery, the piglets' feed intake is relatively small, and the feed level in the mixing tank is correspondingly low. At this time, the original fixed spoiler cannot effectively contact and stir the low-level feed, which leads to insufficient feed mixing. Therefore, the existing liquid feed mixing equipment can only be used in the scene of ordinary fattening houses, and its applicability is poor; in order to be suitable for the feeding of pigs in nursery and fattening houses, new mixing equipment needs to be customized, which will increase the cost of the enterprise. Utility Model Content
[0003] The utility model provides a stirring shaft mechanism with adjustable height, which can solve the technical problem that the spoiler in the existing liquid material stirring equipment is fixed in position and cannot be adjusted according to feeding requirements.
[0004] This application provides the following technical solutions:
[0005] A height-adjustable stirring shaft mechanism comprises a stirring shaft body and a spoiler, wherein the spoiler is slidably mounted on the stirring shaft body via a sliding shaft, and a limit piece is also arranged on the stirring shaft body, and the limit piece is used to limit the circumferential rotation of the sliding shaft; an installation frame is also arranged on the upper part of the stirring shaft body, and a lifting mechanism and a locking assembly are arranged on the installation frame, one end of the lifting mechanism is connected to the sliding shaft, and is used to drive the sliding shaft to perform lifting and lowering movements in the axial direction of the stirring shaft body, and the locking assembly is used to limit the movement of the lifting mechanism.
[0006] Beneficial effects:
[0007] 1. By setting the spoiler on the sliding shaft and setting the sliding shaft sleeve on the stirring shaft body, it is convenient to adjust the height of the spoiler through the lifting mechanism. For example, in the early stage of nursery, by lowering the spoiler to a height close to the liquid level, efficient and uniform stirring can be achieved under low liquid level conditions to meet the piglets' demand for fine feed; as the pigs grow, the feed consumption increases, and the liquid level in the stirring tank rises. At this time, the height of the spoiler can be gradually increased to adapt to the higher liquid level to ensure consistent stirring effect.
[0008] 2. The stirring shaft mechanism of the present application can be used in a variety of feeding scenarios and can be flexibly adjusted according to different feeding requirements, thereby improving the applicability of the stirring equipment; and the modification cost is low, which is beneficial to saving enterprise costs compared to customizing various types of stirring equipment.
[0009] 3. The mounting frame is arranged on the stirring shaft body. When the stirring shaft body rotates and drives the sliding shaft to rotate, the mounting frame and the lifting mechanism and locking assembly arranged on the mounting frame rotate together, which can solve the problem of interference between the sliding shaft and the lifting mechanism when rotating.
[0010] Furthermore, the limiting member is a limiting pin, and a limiting groove is arranged on the sliding shaft along its axial direction, and the limiting pin passes through the limiting groove and is slidably connected to the limiting groove.
[0011] Beneficial effect: By setting the limit pin and the limit groove, it can be ensured that the sliding shaft can only move in the axial direction of the stirring shaft body, and by utilizing the limiting effect of the limit pin, the sliding shaft is driven to rotate when the stirring shaft rotates, thereby driving the spoiler to stir the liquid feed.
[0012] Furthermore, the lifting mechanism includes a rotating shaft and a wire rope. The rotating shaft is rotatably arranged on the installation frame, and both left and right ends extend out of the installation frame. One end of the wire rope is fixed on the rotating shaft, and the other end is connected to the top of the sliding shaft.
[0013] Beneficial effect: when the height of the spoiler needs to be adjusted, the rotating shaft is rotated so that the wire rope is wound around the rotating shaft, thereby raising the height of the sliding shaft; when the height of the spoiler needs to be lowered, the rotating shaft is rotated in the opposite direction, and the adjustment method is simple and quick.
[0014] Furthermore, the locking assembly is arranged on the outside of the installation frame, and the locking assembly includes a ratchet and a pawl. The ratchet is fixedly arranged on the end of the rotating shaft, and the pawl is rotatably arranged on the installation frame, and the pawl is meshed with the ratchet.
[0015] Beneficial effect: One-way motion control is achieved by engaging the ratchet pawl, so that the rotating shaft can only move in the direction of the wound wire rope, thereby increasing the height of the sliding shaft. When the position is determined, the limiting effect of the pawl can prevent the rotating shaft from rotating in the opposite direction under the action of gravity; when the height of the spoiler needs to be lowered, the pawl is turned to disengage it from the ratchet. At this time, under the action of gravity, the rotating shaft rotates in the opposite direction to release the wire rope. When it drops to the appropriate position, the pawl is engaged with the ratchet wheel again.
[0016] Furthermore, the mounting frame is a U-shaped structure, the stirring shaft body is located in the U-shaped groove of the U-shaped structure and is fixedly connected to the inner wall of the U-shaped groove; the rotating shaft is rotatably arranged on two opposite side walls of the U-shaped groove, and both ends of the rotating shaft pass through the side walls of the U-shaped groove.
[0017] Furthermore, a handle is provided at one end of the rotating shaft away from the ratchet wheel, so that the rotating shaft can be rotated conveniently by the handle.
[0018] Furthermore, a hanging ear is provided on the outer wall of the upper end of the sliding shaft, a through hole is provided on the hanging ear, and the steel wire rope is connected to the through hole on the hanging ear.
[0019] Furthermore, the spoiler includes two blades, which are detachably arranged on the lower side wall of the sliding shaft. The detachable arrangement facilitates the replacement of the spoiler.
[0020] Furthermore, each blade section includes a main blade and a secondary blade, the secondary blade is vertically arranged on the main blade, and the main blade is obliquely arranged on a clamping ring, and the two blade sections are fixed on the sliding shaft through the clamping ring.
[0021] Beneficial effect: It is beneficial to improve the turbulence effect and ensure the uniformity of liquid material stirring.
[0022] Furthermore, the clamping ring is an arc-shaped structure, and both ends extend outward to form a connecting portion, and the connecting portions of the two clamping rings are fixed by a locking piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example
[0031] like Figure 1-2As shown, a height-adjustable stirring shaft mechanism includes a stirring shaft body 1 and a spoiler 2, wherein the spoiler 2 is slidably mounted on the stirring shaft body 1 via a sliding shaft 3, and when the stirring shaft body 1 rotates, the sliding shaft 3 rotates together with the stirring shaft body 1; specifically, a limiting pin 11 is provided on the stirring shaft body 1, and a limiting groove 31 is provided on the sliding shaft 3 along its axial direction, the limiting pin 11 passes through the limiting groove 31 and is slidably connected to the limiting groove 31; the limiting pin 11 and the limiting groove 31 are used to limit the sliding shaft 3 so that it can only move in the axial direction of the stirring shaft body 1, and no relative movement in the circumferential direction occurs.
[0032] The upper part of the stirring shaft body 1 is also fixedly provided with a mounting frame 4, on which a lifting mechanism 5 and a locking assembly 6 are provided. One end of the lifting mechanism 5 is connected to the sliding shaft 3 to drive the sliding shaft 3 to move up and down in the axial direction of the stirring shaft body 1, and the locking assembly 6 is used to limit the movement of the lifting mechanism 5. Figure 3 As shown, in this embodiment, the mounting frame 4 is a U-shaped structure, and the agitator shaft body 1 is located in a U-shaped groove of the U-shaped structure. The U-shaped groove can be fixedly connected to the agitator shaft body 1 by a U-shaped bolt (the U-shaped bolt is not shown in the figure); in order to further improve the stability of the connection, a limiting rod 12 is also provided on the agitator shaft body 1 in this embodiment, and the limiting rod 12 passes through the groove wall of the U-shaped groove.
[0033] The lifting mechanism 5 includes a rotating shaft 51 and a steel wire rope 52. The rotating shaft 51 is rotatably arranged on two opposite side walls of the mounting frame 4, and both left and right ends extend out of the side walls of the mounting frame 4. In order to facilitate the rotation of the rotating shaft 51, a handle 511 is also arranged on one end of the rotating shaft 51; one end of the steel wire rope 52 is fixed on the rotating shaft 51, and the other end is connected to the top of the sliding shaft 3; specifically, Figure 4 As shown, a lug 32 is further provided on the outer wall of the upper end of the sliding shaft 3, and a through hole is provided on the lug 32, and a steel wire rope 52 is connected to the through hole on the lug 32. When the height of the spoiler 2 needs to be adjusted, the rotating shaft 51 is rotated so that the steel wire rope 52 is wound around the rotating shaft 51, thereby raising the height of the sliding shaft 3; when the height of the spoiler 2 needs to be lowered, the rotating shaft 51 is rotated in the opposite direction.
[0034] like Figure 3As shown, the locking assembly 6 is arranged on the outside of the mounting frame 4, specifically on the outer wall of the mounting frame 4 away from the handle 511; the locking assembly 6 includes a ratchet 61 and a pawl 62, the ratchet 61 is fixedly arranged at the end of the rotating shaft 51, the pawl 62 is rotatably arranged on the side wall of the mounting frame 4, and the pawl 62 is meshed with the ratchet 61. The one-way motion control is realized by meshing the ratchet 61 and the pawl 62, so that the rotating shaft 51 can only move along the direction of winding the wire rope 52, thereby raising the height of the sliding shaft 3. When the position is determined, due to the limiting effect of the pawl 62, the rotating shaft 51 can be prevented from rotating in the opposite direction under the action of gravity or due to accidental collision; when the height of the spoiler 2 needs to be lowered, the pawl 62 is rotated to disengage the ratchet 61, at this time, under the action of gravity, the rotating shaft 51 rotates in the opposite direction to release the wire rope 52, and when it is lowered to a suitable position, the pawl 62 is meshed with the ratchet 61 again.
[0035] In this embodiment, the spoiler 2 includes two blades, and the two blades are detachably arranged on the lower side wall of the sliding shaft 3; Figure 5 As shown, each blade section includes a main blade 21 and a secondary blade 22, the secondary blade 22 is vertically arranged on the blade of the main blade 21, and the main blade 21 is obliquely arranged on the clamping ring 23, and the two blade sections are fixed on the sliding shaft 3 through the clamping ring 23. In this embodiment, the clamping ring 23 is an arc-shaped structure, and both ends extend outward to form a connecting portion 231, and the connecting portions 231 of the two clamping rings 23 are locked and fixed by bolts.
[0036] When the present application is used, the height of the sliding shaft 3 can be adjusted according to the liquid level of the feed, and then the height of the spoiler 2 can be adjusted, so that the spoiler 2 is in the liquid level to effectively stir the liquid material and improve the uniformity of the stirring of the liquid material; during the specific adjustment, hold the handle 511 and rotate the rotating shaft 51, so that the wire rope 52 is wound around the rotating shaft 51, thereby raising the height of the sliding shaft 3, and stop rotating when it is lifted to the appropriate position. At this time, due to the meshing action of the ratchet 61 and the pawl 62, the rotating shaft 51 is locked; when it is necessary to lower the height of the spoiler 2, the pawl 62 is moved to disengage it from the ratchet 61. At this time, the rotating shaft 51 is rotated in the opposite direction to release the wire rope 52, and the sliding shaft 3 moves downward along the stirring shaft body 1. When it is adjusted to the appropriate position, the pawl 62 is moved again to engage it with the ratchet 61 to lock the rotating shaft 51.
[0037] Through a simple and novel design, the present application achieves the goal of adjusting the height of the spoiler 2 on the stirring shaft body 1 according to the amount of feeding required by pigs at different times, thereby ensuring that the feed can be fully stirred; improving the applicability of the stirring equipment; and having a low modification cost, which is beneficial to saving corporate costs compared to customizing various types of stirring equipment.
