Description

Technical Field

[0001] This utility model relates to the field of pig farming technology, specifically to a feed mixing device for pig farming. Background Technology

[0002] As an important part of animal husbandry, pig farming relies heavily on feed, which is crucial to both farming efficiency and pig quality. Pigs have significantly different nutritional needs at different growth stages, and a single ingredient cannot meet these needs. Therefore, it is necessary to formulate balanced feeds by mixing various ingredients to ensure healthy growth, enhance immunity, and maximize farming efficiency. At the same time, feed mixing also helps to rationally utilize resources and promote sustainable development. It can reduce costs by leveraging regional raw material advantages and improve feed digestibility through formulation, thereby reducing livestock waste emissions and contributing to the coordinated development of pig farming and environmental protection.

[0003] According to the authorization announcement number (CN210445264U), a feed mixing and feeding machine for pig farming includes a support plate and a mixing tank. The support plate is fixedly connected to a push plate, and wheels are provided at the bottom of the support plate. In actual operation, the entire machine is moved to a suitable feeding position in the farm; then, the feed ingredients to be mixed are put into the mixing tank to complete the uniform mixing of the feed; after the feed is mixed to the required standard, the mixed feed is transported to the pig trough through the feeding pipe, realizing a continuous operation of mixing and feeding.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: Although the whole machine can be moved by relying on wheels to get closer to the preset pig trough and realize the delivery of mixed feed to the pig trough by the feeding pipe, in the pig farming scenario, the height of the feeding trough corresponding to different growth stages (such as piglets, fattening pigs, and sows) is generally different. The fixed height feeding pipe cannot adapt to the height requirements of multi-sized feeding troughs and is difficult to meet the efficient feeding needs in multiple scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a feed mixing device for pig farming, which addresses the problem in the existing technology that it is difficult to adapt to the height of multiple feed troughs corresponding to pigs at different growth stages (piglets, fattening pigs, and sows). It proposes a solution that can adapt to the height of multiple pig feed troughs corresponding to pigs at different growth stages, significantly improving the applicability in diverse farming scenarios.

[0006] This utility model is achieved through the following technical solution:

[0007] A feed mixing device for pig farming includes: a support base; a rolling assembly mounted on the support base; two support brackets mounted on opposite sides of the support base; a mixing cylinder rotatably mounted between the two support brackets, the lower side of the mixing cylinder having a funnel structure with a discharge port at the bottom end; a telescopic pipe connected to the discharge port; a mixing assembly mounted on the mixing cylinder; and a drive assembly mounted on the support brackets, capable of driving the mixing cylinder to rotate to a preset tilt angle, thereby adjusting the discharge end of the telescopic pipe to a corresponding height.

[0008] Furthermore, in this utility model, the telescopic tube body includes multiple telescopic tube sections that are nested together in sequence, and the inner diameter of the multiple telescopic tube sections increases in a stepwise manner along the direction away from the discharge port; wherein, in two adjacent telescopic tube sections, one telescopic tube section is fitted onto the outside of the other telescopic tube section to form a sliding guide fit, and the inner space of the two adjacent telescopic tube sections constitutes a closed conveying channel for feed circulation.

[0009] Furthermore, in this utility model, the outer side wall of the telescopic tube section is provided with at least one sliding guide groove along the extension direction, and the inner side wall of the telescopic tube section is provided with a corresponding guide slider; wherein, in the assembled state of two adjacent telescopic tube sections, the guide slider of one telescopic tube section is correspondingly embedded in the sliding guide groove of the other telescopic tube section.

[0010] Furthermore, in this utility model, a sleeve is installed at the bottom end of the funnel structure, and the sleeve surrounds the outside of the telescopic tube body; the sleeve has a through-type assembly groove, and a limiting component is installed in the assembly groove; a limiting groove is opened on the outer side wall of the outermost telescopic tube section; wherein, when multiple telescopic tube sections are contracted and located inside the sleeve, the limiting component can form a limiting fit with the limiting groove, thereby limiting the multiple telescopic tube sections together inside the sleeve.

[0011] Furthermore, in this utility model, the aforementioned limiting component includes: a limiting pin, which passes through the assembly groove; and a return spring, which is fitted on the outside of the limiting pin, with one end of the return spring connected to the outer side wall of the limiting pin and the other end of the return spring connected to the inner side wall of the assembly groove; wherein, when the return spring is in its natural state, the limiting pin can be embedded in the limiting groove to form a limiting fit.

[0012] Furthermore, in this utility model, the outer walls of the aforementioned multiple telescopic tube sections are respectively provided with positioning grooves; wherein, the limiting pin can cooperate with the preset positioning groove to limit the corresponding telescopic tube section from extending out of the sleeve, and the telescopic tube section located outside the limited telescopic tube section in the telescopic tube body can continue to extend, thereby controlling the length of the telescopic tube body.

[0013] Furthermore, in this invention, the aforementioned rolling assembly includes multiple rollers, which are rotatably mounted on a support base.

[0014] Furthermore, in this utility model, the above-mentioned mixing component includes: a first motor, which is installed at the top of the mixing cylinder; a mixing main shaft, one end of which is connected to the output end of the first motor, and the other end of which extends into the mixing cylinder; and a plurality of mixing blades, which are installed on the mixing main shaft.

[0015] Furthermore, in this utility model, the aforementioned drive assembly includes: a mounting base mounted on a support bracket; a second motor mounted on the mounting base; and a drive spindle, one end of which is connected to the output end of the second motor, and the other end of which is connected to the mixing cylinder.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] 1. This utility model adjusts the tilt angle of the mixing cylinder through a drive component, forming a dual height adjustment structure combined with multi-section nested telescopic tubes. In feeding mode, it adapts to the trough height corresponding to pigs at different growth stages; in non-operation storage mode, the telescopic tubes can retract into the sleeve to reduce the overall volume. It can easily adapt to different breeding scenarios such as piglets, finishing pigs, and sows, meeting the needs of multi-pen mobile feeding, significantly reducing the device's adaptability to the breeding environment, and simplifying feeding operations.

[0018] 2. This utility model features a limiting component at the sleeve, which can limit the retracted telescopic tube. In the non-operating state, the telescopic tube is confined within the sleeve by the limiting component, preventing the telescopic tube section from extending unexpectedly, effectively reducing the space occupied when the device is stored, and facilitating transportation and storage.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0028] Example

[0029] Please refer to Figures 1 to 5 This utility model provides a feed mixing device for pig farming. It includes a support base 1; a rolling assembly mounted on the support base 1 for moving the entire device; two support brackets 2 symmetrically installed on opposite sides of the support base 1 to form a support structure; a mixing cylinder 4 mounted between the two support brackets 2 via a rotating connection structure, allowing for angle adjustment around the support brackets 2; a funnel structure on the lower side of the mixing cylinder 4 with a discharge port 8 at its bottom for feed discharge; a telescopic tube 14, one end of which is sealed to the discharge port 8 for receiving and guiding the discharged feed; a mixing component mounted on the mixing cylinder 4 for stirring and mixing the feed ingredients within the mixing cylinder 4; and a drive component mounted on the support brackets 2, with its power output end connected to the mixing cylinder 4, capable of driving the mixing cylinder 4 to rotate to a preset tilt angle, thereby synchronously adjusting the discharge end of the telescopic tube 14 to a height suitable for the pig feed trough.

[0030] On the one hand, eliminating the storage step after premixing feed can prevent the loss of activity of heat-sensitive or easily degradable nutrients such as vitamins, probiotics, and enzymes in the feed due to the influence of the storage environment (temperature, humidity, light), while also preventing the growth of mold in mixed feed due to poor air permeability between particles; on the other hand, it can adjust the feed ingredient ratio in real time according to different growth stages of pigs or breeding needs, thereby improving the adaptability of the formula.

[0031] The specific operating procedure is as follows: The operator pushes the bearing base 1 to the side of the pig feed trough through the rolling component, and puts the required feed raw materials into the feed port 7 above the mixing cylinder 4; the mixing component is started to evenly mix the raw materials; according to the actual height of the pig feed trough, the mixing cylinder 4 is driven to rotate to the preset tilt angle through the drive component, and the extension length of the telescopic tube 14 is adjusted so that the discharge end of the telescopic tube 14 extends into the pig feed trough; at this time, the mixed feed flows to the discharge port 8 by gravity in the tilted mixing cylinder 4, and is transported to the pig feed trough through the telescopic tube 14.

[0032] The design of the telescopic tube 14 extending into the pig feed trough can avoid the problem of splashing caused by the height difference when the feed is discharged. The structure of adjusting the tilt angle of the mixing cylinder 4 by the drive component to change the height of the telescopic tube 14 can be adapted to pig feed troughs of different heights, thus avoiding the situation where the feed is not delivered in place.

[0033] For example, a valve is installed at the discharge port 8. The core function of the valve is to control the on / off state of the discharge port 8 to start and stop the feed conveying. During feed conveying operations, the operator adjusts the opening and closing of the discharge port 8 by opening and closing the valve. In terms of adaptability, the valve can be a plug, ball valve, or solenoid valve, etc.

[0034] It should be noted that bearings are installed on both support brackets 2, and rotating shafts 3 are coaxially arranged on opposite sides of the mixing cylinder 4. The rotating shafts 3 and the bearings on the corresponding support brackets 2 form a coaxial rotational fit, realizing low-friction rotation of the mixing cylinder 4 around the support brackets 2, and providing a reliable rotational support foundation for the drive assembly to drive the mixing cylinder 4 to adjust the tilt angle.

[0035] Please refer to Figure 2 In some embodiments of this application, the telescopic tube 14 is composed of multiple telescopic tube sections 21 nested in sequence. The inner diameter of each telescopic tube section 21 is arranged in a stepped manner along the direction away from the discharge port 8 of the mixing cylinder 4. Between two adjacent telescopic tube sections 21, the telescopic tube section 21 with a smaller inner diameter can be slidably fitted inside the telescopic tube section 21 with a larger inner diameter to form a sliding guide fit. The inner space of two adjacent telescopic tube sections 21 together encloses to form a closed conveying channel for feed circulation.

[0036] The aforementioned nested structure, through its stepped increasing inner diameter design, allows the telescopic tube 14 to flexibly adjust its extension length according to actual farming scenarios. For example, it can adapt to pig feed troughs with different heights in different pens, or address different horizontal distances between the device and the feed trough, ensuring that the discharge end of the telescopic tube 14 can connect to the pig feed trough. On the other hand, during the conveying process, the feed flows from the section with the smaller inner diameter to the section with the larger inner diameter, effectively preventing feed from getting stuck or remaining in the gap between adjacent telescopic tube sections 21. This ensures the cleanliness of the conveying channel and achieves lossless feed conveying.

[0037] Please refer to Figure 4 Specifically, the outer side wall of the telescopic tube section 21 is provided with at least one sliding guide groove 22, and the inner side wall of the telescopic tube section 21 that is adapted to it is correspondingly installed with a guide slider 23; in the assembled state of two adjacent telescopic tube sections 21, the guide slider 23 of one telescopic tube section 21 can be correspondingly embedded in the sliding guide groove 22 of the other telescopic tube section 21 to form an axial sliding limiting fit.

[0038] The above structural design ensures that adjacent telescopic sections 21 can slide relative to each other. In the retracted position, all telescopic sections 21 can be nested and retracted in sequence, so that the telescopic tube body 14 is retracted to its minimum size, reducing the space occupied by the device in the non-operating state. On the other hand, the sliding guide groove 22 and the guide slider 23 are both set in the side wall interlayer area of ​​the telescopic section 21, which is completely isolated from the main channel inside the telescopic section 21 for feed flow. During the feed conveying process, the feed only flows in the main channel inside the telescopic section 21 and will not enter the gap between the sliding guide groove 22 and the guide slider 23. Structurally, this avoids the problems of telescopic jamming or channel contamination caused by feed accumulation.

[0039] In some embodiments of this application, a sleeve 5 is coaxially mounted at the bottom end of the funnel structure, and the sleeve 5 is sleeved on the outside of the telescopic tube body 14 in an enclosing form; a through-type assembly groove 18 is opened on the side wall of the sleeve 5, and a limiting component is installed in the assembly groove 18; correspondingly, the outer side wall of the outermost telescopic tube section 21 of the telescopic tube body 14 is provided with a limiting groove 15 adapted to the limiting component.

[0040] When multiple telescopic pipe sections 21 retract axially and are housed inside the sleeve 5, the limiting component can engage with the limiting groove 15 of the outermost telescopic pipe section 21 to limit and fix all telescopic pipe sections 21 inside the sleeve 5, ensuring that the telescopic pipe sections 21 will not extend unexpectedly in non-operational conditions.

[0041] Please refer to Figure 2 and Figure 3Specifically, the limiting component includes a limiting pin 17 and a return spring 19; the limiting pin 17 is movably inserted into the assembly channel 18, and the return spring 19 is coaxially fitted on the outside of the limiting pin 17, with one end of the return spring 19 connected to the outer peripheral wall of the limiting pin 17 and the other end connected to the inner side wall of the assembly channel 18.

[0042] When the return spring 19 is in its natural state, the limiting pin 17 can extend into the limiting groove 15 to form a limiting engagement. When the multiple telescopic tube sections 21 retract axially and are housed inside the sleeve 5, the limiting pin 17, under the elastic potential energy of the return spring 19, engages with the limiting groove 15 of the outermost telescopic tube section 21, thus constraining all the telescopic tube sections 21 as a whole inside the sleeve 5 through the locking and limiting action. During feed conveying operations, the operator pulls the limiting pin 17 to compress the return spring 19, causing the limiting pin 17 to completely disengage from the limiting groove 15, allowing the multiple telescopic tube sections 21 to extend axially in sequence and into the pig feed trough.

[0043] For example, the outer side walls of multiple telescopic tube sections 21 are provided with positioning grooves 16; the limiting pins 17 can form a selective limiting engagement with the preset positioning grooves 16 to constrain the extension action of the corresponding telescopic tube section 21, while the remaining telescopic tube sections 21 located outside the constrained telescopic tube section 21 can still continue to extend, realizing the graded adjustment of the length of the telescopic tube body 14.

[0044] Based on the actual conditions such as the location of the pig feed trough and the terrain, the operator can control the corresponding number of telescopic pipe sections 21 to extend out of the sleeve 5. By inserting the limiting pin 17 into the positioning groove 16 of the telescopic pipe section 21 that is currently on the outermost side of the sleeve 5, the corresponding length of the telescopic pipe body 14 can be locked.

[0045] It should be noted that during the feed conveying process, the mixing cylinder 4 maintains an inclined posture, which drives the telescopic tube 14 to be arranged in an inclined position simultaneously. In this state, multiple telescopic tube sections 21 located outside the sleeve 5 can naturally extend with the help of gravity, so that the outermost telescopic tube section 21 can be accurately inserted into the pig feed trough, ensuring the smooth progress of the feed conveying process.

[0046] In some embodiments of this application, the rolling assembly includes multiple rollers 6, which are assembled on the support base 1. Preferably, there are four rollers 6, which are respectively arranged at the four corners of the support base 1 to form a support and movement structure, ensuring that the whole device can be flexibly transported.

[0047] Please refer to Figure 1 and Figure 5In some embodiments of this application, the mixing assembly consists of a first motor 12, a mixing main shaft 24, and a plurality of mixing blades 20; the first motor 12 is mounted on the top of the mixing cylinder 4, one end of the mixing main shaft 24 is connected to the output end of the first motor 12 for transmission, and the other end extends axially into the interior of the mixing cylinder 4, and the plurality of mixing blades 20 are installed at intervals along the axial direction of the mixing main shaft 24.

[0048] In operation, the first motor 12 drives the mixing spindle 24 to rotate the mixing blades 20, thereby achieving uniform mixing of feed ingredients in the mixing cylinder 4. The structural parameters of the mixing blades 20 are adapted and optimized to ensure that their rotation trajectory maintains a safe gap with the inner wall of the mixing cylinder 4 to avoid interference. For the funnel structure at the bottom of the mixing cylinder 4, the mixing blades 20 in the corresponding area adopt an adaptive size design to match the funnel-shaped space, ensuring both the integrity of the mixing coverage and the structural safety during operation.

[0049] Please refer to Figure 1 In some embodiments of this application, the drive assembly consists of a mounting base 9, a second motor 10, and a drive spindle 11. The mounting base 9 is mounted on the support bracket 2, the second motor 10 is mounted on the mounting base 9, one end of the drive spindle 11 is connected to the output end of the second motor 10, and the other end is connected to the mixing cylinder 4. Rotating shafts 3 are coaxially arranged on opposite sides of the mixing cylinder 4, and the drive spindle 11 is engaged with one of the rotating shafts 3 for power transmission. In operation, the second motor 10 outputs torque through the drive spindle 11, driving the mixing cylinder 4 to rotate to a preset tilt angle, thereby controlling the attitude of the mixing cylinder 4.

[0050] It should be noted that, in response to the increased load on the mixing cylinder 4 under multiple feed mixing conditions, a gear transmission structure can be used to optimize the power output. Specifically, a small gear is installed at the output end of the drive shaft 11, and a large gear is installed on the rotating shaft 3 of the mixing cylinder 4. The meshing of the small gear and the large gear forms a reduction mechanism to improve the torque output capability, ensuring that the mixing cylinder 4 can be driven to rotate and meet the load requirements when mixing multiple feeds.

[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
