Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

The wall-sticking preventive feed stirring device of the present invention is described below with reference to fig. 1 to 8.

As shown in fig. 1 to 7, the wall-sticking preventing feed stirring device of the present invention comprises a frame body 1, a bucket 2 and a stirring unit 3. The charging basket 2 extends vertically and is arranged on the frame body 1, the upper end of the charging basket 2 is of an open structure, and feed which can be a mixture of various raw materials is conveniently put into the charging basket 2.

The frame 1 is provided with a frame 4, the frame 4 is rotatably provided with a central shaft 41 which is coaxial with the charging basket 2 and is arranged in the charging basket 2, and the frame 4 is provided with a power device 42 for driving the central shaft 41 to rotate. The power device 42 is preferably a motor, a main shaft of the motor is fixedly connected with the central shaft 41, and when the motor is started, the main shaft is driven to rotate, and the main shaft drives the central shaft 41 to rotate. The stirring units 3 are arranged in the charging basket 2, and the stirring units 3 are distributed at equal intervals along the circumferential direction of the central shaft 41. The number of stirring units 3 is preferably 3, but may be other number, and the present embodiment is not limited thereto.

The following description will take one of the stirring units 3 as an example: the stirring unit 3 includes a support shaft 31 and a blade 32, and the support shaft 31 extends in the radial direction of the center shaft 41 and is elastically slidably connected to the center shaft 41. The circumferential surface of the support shaft 31 is provided with a guide groove 311 spirally provided along the axis of the support shaft 31, and the pitch of the guide groove 311 is much larger than the diameter of the support shaft 31. The length direction of the blade 32 is consistent with the axial direction of the support shaft 31, the width direction of the blade 32 is obliquely arranged from top to bottom, the blade 32 is provided with a shaft hole 321 extending along the length direction of the blade 32, the blade 32 is sleeved on the support shaft 31 through the shaft hole 321, the peripheral wall of the shaft hole 321 is provided with a guide push rod 322 matched in the guide groove 311, and a first elastic piece 33 is connected between the blade 32 and the support shaft 31, so that when the blade 32 rotates along with the central shaft 41, the blade 32 can move spirally along the axis of the support shaft 31 under the resistance of viscous feed in the feed bucket 2.

When the center shaft 41 rotates, the blade 32 is driven to rotate around the axis of the center shaft 41 by the transmission of the support shaft 31. At this time, the feed in the barrel 2 is not added with water and additive, the resistance to the blade 32 is not particularly high, the inclination angle of the surface of the blade 32 is small, and the rotating blade 32 can stir the feed. It should be noted that the inclination of the blade 32 is not greatly deviated at this time, so that axial flow stirring can be provided for the feed, and the feed can be circulated along the axial direction of the central shaft 41, thereby realizing thorough mixing of various raw materials in the feed.

After the feed is stirred for a period of time, water and additives are added into the feed, the feed gradually becomes viscous, and the resistance of the feed increases. At this time, the blade 32 is deflected about the axis of the fulcrum 31 by the resistance of the feed, and drives the guide push rod 322 to slide in the guide groove 311, and the sliding of the guide push rod 322 in turn reacts to the blade 32 and causes the blade 32 to move spirally about the axis of the fulcrum 31. The helical movement of the blade 32 at this time can be decomposed into a deflection about the axis of the fulcrum 31 and a movement in the axial direction of the fulcrum 31. Deflection of the blade 32 about the axis of the fulcrum 31 causes deformation of the first elastic member 33, whereby the first elastic member 33 stores force. The axial movement of the blades 32 along the fulcrum 31 causes the blades 32 to move progressively away from the central axis 41 and towards the inner peripheral wall of the bowl 2.

When the end of the blade 32 away from the central shaft 41, i.e. the edge of the blade 32 abuts against the inner peripheral wall of the bowl 2, the movement of the blade 32 along the axial direction of the fulcrum 31 is stopped by the blocking action of the inner peripheral wall of the bowl 2. At this time, the resistance of the feed still acts on the blade 32, the blade 32 will continue to deflect around the axis of the support shaft 31 and drive the guide push rod 322 to rotate, the support shaft 31 will move towards the central shaft 41 along the axial direction under the driving action of the guide push rod 322 and the guide groove 311, and the elastic force between the support shaft 31 and the central shaft 41 will increase due to the elastic sliding connection of the support shaft 31 and the central shaft 41. The elastic force acts on the blades 32 through the supporting shafts 31, so that the blades 32 are tightly pressed against the inner peripheral wall of the charging basket 2. When the elastic force accumulated by the first elastic member 33 can be balanced with the resistance generated by the feed, the deflection of the blade 32 about the axis of the support shaft 31 is stopped. Subsequently, when the blade plate 32 continuously stirs the feed, the edge of the blade plate 32 can continuously scrape the feed adhered to the inner peripheral wall of the feed bucket 2 because the edge of the blade plate is propped against the inner peripheral wall of the feed bucket 2, so that the feed is prevented from caking, the feed is prevented from being exposed to the air for a long time, the mildew is prevented, the quality of the feed is ensured, and the adverse effect on the health of animals is avoided.

In addition, since the paddle 32 has been deflected about the axis of the support shaft 31 at this time, the inclination angle of the plate surface of the paddle 32 increases. The paddles 32, which thereafter rotate with the central shaft 41, can provide a stronger shearing action on the viscous feed, further enhancing the mixing effect of the feed. In the present embodiment, the inclined posture of the blade 32 is changed with the change of the viscosity of the feed, so that the feed can be adaptively stirred according to the viscosity of the feed, and the mixing efficiency of the feed as a whole is improved.

Specifically, the charging basket 2 is provided with a heating element for heating the feed in the charging basket 2, and the specific form of the heating element can be an electric heating tube, an electric heating ring, an electric heating wire and the like, which are the prior art and are not described herein. It will be appreciated that the heating element may be embedded in the wall of the barrel 2, the heating element first heating the wall of the barrel 2 and then conducting heat from the wall of the barrel 2 to the feed in the barrel 2. The heating element is used for maintaining the constant temperature environment of the feed in the charging basket 2.

Specifically, the central shaft 41 is sleeved with a collar 43, the collar 43 is provided with a sliding groove 431 arranged along the radial direction of the collar 43, one end of the sliding groove 431 penetrates through the collar 43 towards the outer side of the collar 43, the other end of the sliding groove 431 extends into the central shaft 41, one end, close to the central shaft 41, of the support shaft 31 is provided with a sliding column 312, the length direction of the sliding column 312 is consistent with the axial direction of the support shaft 31, the cross section of the sliding column 312 is square, the sliding column 312 is in sliding fit in the sliding groove 431, and a second elastic piece 34 is connected between the sliding column 312 and the collar 43. The second elastic member 34 includes a spring, a ring plate 35 is provided at a joint between the slide post 312 and the support shaft 31, the spring is sleeved on an outer peripheral side of the slide post 312, and two ends of the spring are fixedly connected with the collar 43 and the ring plate 35, respectively.

The sliding groove 431 is used to guide the movement of the slide post 312 and the support shaft 31, when the support shaft 31 moves toward the center shaft 41, the spring is compressed and starts to accumulate, and the elastic force accumulated by the spring acts on the blade 32 through the support shaft 31, so that the blade 32 can be tightly pressed against the inner peripheral wall of the bowl 2.

A telescopic tube (not shown in the figure) sleeved on the outer peripheral side of the second elastic member 34 is connected between the blade plate 32 and the central shaft 41, specifically, the telescopic tube comprises an inner tube and an outer tube, the inner tube and the blade plate 32 are fixedly connected and sleeved on the outer peripheral side of the second elastic member 34, the outer tube and the central shaft 41 are fixedly connected and sleeved on the inner tube, and the tube walls of the inner tube and the outer tube are attached. The inner and outer tubes serve to protect the second resilient member 34 and the slide post 312 from feed within the bowl 2 affecting the use of the second resilient member 34 and the slide post 312.

As can be appreciated, the peripheral wall of the slide groove 431 is provided with four guide grooves uniformly distributed along the circumferential direction of the fulcrum shaft 31, the guide grooves extend in the axial direction of the fulcrum shaft 31, both ends of the guide grooves are closed, and the slide posts 312 are provided with guide blocks which are equal in number to the guide grooves and correspond to each other one by one, and the guide blocks are slidably fitted in the corresponding guide grooves. The guide block and guide slot design prevents the slide post 312 from escaping the slide groove 431 when sliding in the slide groove 431.

Specifically, the first elastic member 33 includes a torsion spring, one end of the blade 32 adjacent to the central shaft 41 is provided with a ring groove 323 coaxial with the shaft hole 321, the diameter of the ring groove 323 is larger than that of the shaft hole 321, the ring groove 323 and the shaft hole 321 are radially spaced apart, the torsion spring is coaxial with the ring groove 323 and is disposed in the ring groove 323, one end of the torsion spring is fixedly connected with the blade 32, and the other end of the torsion spring extends out of the ring groove 323 and is fixedly connected with the ring plate 35.

In some embodiments, as shown in fig. 3, 4, 6, 7 and 8, description will be given by taking one of the stirring units 3 as an example: the vane 32 has a front side 324 and a rear side 325 opposite to each other in the rotation direction when rotating with the central shaft 41, the front side 324 of the vane 32 is provided with a baffle 327 parallel to and spaced apart from the front side 324 of the vane 32, an edge portion 328 surrounding a periphery of the baffle 327 is connected between an edge of the baffle 327 and the front side 324 of the vane 32, the edge portion 328 forms a flow chamber 3281 between the baffle 327 and the vane 32, the edge portion 328 is provided with an inlet 3282 communicating the flow chamber 3281 and the outside, the inlet 3282 is near one end of the vane 32 facing away from the central shaft 41, the inlet 3282 faces the inner peripheral wall of the bucket 2 in the length direction of the vane 32, the vane 32 is provided with an outlet 326 communicating the flow chamber 3281 and extending from the front side 324 of the vane 32 to the rear side 325 of the vane 32, and the outlet 326 is near the central shaft 41 relative to the inlet 3282.

When the inclination angle of the vane 32 becomes larger and presses against the inner peripheral wall of the barrel 2, the central shaft 41 scrapes the feed adhered to the inner peripheral wall of the barrel 2 by the edge of the vane 32 in the process of continuing to rotate with the vane 32, the scraped feed continuously flows into the flow cavity 3281 from the inlet 3282 under the extrusion action of the feed which is not scraped, and the feed flowing into the flow cavity 3281 further flows out through the outlet 326 under the action of the mutual extrusion of the feed. The design makes the flow chamber 3281 can be with the position of leading-in export 326 of the fodder that scrapes from the interior perisporium of storage bucket 2, i.e. the inboard of storage bucket 2, has avoided the blade 32 to pass through the back, and the fodder that scrapes again adheres to on the interior perisporium of storage bucket 2.

In addition, the inlet 3282 is arranged towards the inner peripheral wall of the barrel 2 in such a way that the feed just scraped from the inner peripheral wall of the barrel 2 smoothly flows into the inlet 3282. In other words, the arrangement mode of the inlet 3282 limits the feed entering position, that is, the feed between the inlet 3282 and the inner peripheral wall of the barrel 2 is easier to flow into the inlet 3282, and most of the feed between the inlet 3282 and the inner peripheral wall of the barrel 2 is the feed adhered to the inner peripheral wall of the barrel 2, so that the arrangement mode of the inlet 3282 is more beneficial to the feed scraped from the inner peripheral wall of the barrel 2, the feed entering inside the barrel 2 is reduced, and the feed inside the barrel 2 is prevented from occupying the flow cavity 3281 to prevent the feed scraped from the inner peripheral wall of the barrel 2 from flowing into.

Specifically, the stirring units 3, the collar 43 and the chute 431 form a stirring assembly 300, the stirring assembly 300 has a plurality of blades 32 and is equally spaced in the axial direction of the central shaft 41, and after the blades 32 stop against the inner peripheral wall of the bowl 2 during the spiral movement, the blade 32 of the lowermost one of the stirring assemblies 300 can contact with the bottom wall of the bowl 2.

Therefore, when the inclination angle of the blade plate 32 is increased and the blade plate 32 is stopped against the inner peripheral wall of the charging basket 2, and the central shaft 41 carries the blade plate 32 to rotate continuously, the blade plate 32 of the stirring assembly 300 positioned at the lowest position can scrape off the feed adhered to the bottom wall of the charging basket 2, so that the adhesion of the feed is avoided.

In addition, the setting of a plurality of stirring subassemblies 300 has increased the stirring scope to the interior fodder of storage bucket 2 for the fodder can be more even by the stirring ground in the storage bucket 2, has promoted the mixed effect of fodder. Notably, the paddles 32 in the plurality of agitator assemblies 300 may cover substantially all of the bowl 2 from top to bottom after the paddles 32 are fully extended by the viscous feed.

The two linear driving devices 5 are respectively arranged at the left side and the right side of the frame 4, and the left end and the right end of the frame 4 are respectively connected with the output ends of the two linear driving devices 5.

When the two linear driving devices 5 are operated synchronously, the rack 4 can be controlled to move up and down, and the rack 4 can drive the central shaft 41 to enter and exit the charging basket 2 from the top of the charging basket 2, so that the stirring assembly 300 can enter and exit the charging basket 2 conveniently. When the charging basket 2 is placed or taken down on the frame body 1, the central shaft 41 and the stirring assembly 300 can be lifted to the upper part of the charging basket 2, so that the interference of the stirring assembly 300 during the taking and placing process of the charging basket 2 is avoided.

Specifically, the linear driving device 5 includes any one of an electric push rod, a hydraulic cylinder, and an air cylinder.
