Description

Technical Field

[0001] The invention relates to the technical field of feed processing equipment, and in particular to molasses adding equipment for feed. Background Art

[0002] There are many purposes for adding honey to feed, mainly including: 1. Honey is rich in natural sugars, which can provide extra energy, especially when it is necessary to increase the animal's physical strength; 2. Improve the taste: The sweetness of honey can increase the attractiveness of feed, making animals more willing to eat, especially for some animals (such as piglets or young animals); 3. Increase nutrition: Honey contains some trace elements, vitamins and minerals, which can provide additional nutritional support; 4. Promote digestion: Honey can stimulate the secretion of digestive juices and help animals better digest other ingredients; 5. Improve the adhesion of feed particles: Honey, as a natural adhesive, can help feed particles stick together better, reduce dust and waste; 6. Extend the shelf life: Honey has natural antibacterial and antiseptic properties, which can help extend the shelf life of feed. When adding honey, you need to use feed mixing equipment to evenly mix the honey in the feed.

[0003] At present, the commonly used feed mixing equipment mainly uses vertical mixers and drum mixers. The vertical mixer mixes the feed in the vertical direction and is usually equipped with rotating blades; the drum mixer achieves mixing by rolling and flipping. The existing equipment is single mixing with low mixing efficiency. Especially when adding honey, long-term mixing may cause excessive mixing of honey and feed, thus affecting the texture and performance of the product. At the same time, since honey needs to be mixed with water and then mixed with feed when mixed with dry feed, the existing equipment cannot do it at the same time, and additional stirring equipment is required. In the document (application number: CN201821982467.0), a molasses adding device is disclosed, which also sets a stirring device on the top of the mixing device. The device is large in size and is only suitable for vertical mixers. Since the mixing tank of the drum mixer rotates, it is impossible to add honey while mixing, and the addition needs to be completed at one time, which affects the mixing uniformity. Summary of the invention

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Embodiment 1, as Figure 1-Figure 8 As shown, a molasses adding device for feed includes a control frame 1, a mixing tank 3 is rotatably mounted inside the control frame 1, the cross section of the mixing tank 3 is heart-shaped, and two groups of feeding ports 31 are arranged on the top of the mixing tank 3;

[0033] A stirring rod 4 is rotatably installed inside the mixing tank 3. The stirring rod 4 is Y-shaped and hollow inside. A sliding piston 42 is installed inside the two branches above the stirring rod 4. A counterweight inner core 43 is provided inside the piston 42. A plurality of groups of liquid adding branches 44 are arranged in a ring shape on the outer side of the stirring rod 4. A one-way valve 45 is provided at the outlet of the liquid adding branch 44. A stopper sleeve 47 is slidably connected inside the stirring rod 4. The stopper sleeve 47 can block the liquid adding branch 44. A cross brace is provided at the bottom of the stopper sleeve 47, a valve plate 49 is provided at the top of the stopper sleeve 47, and a tension spring 410 is provided between the valve plate 49 and the cross brace.

[0034] Before stirring, first add the feed into the mixing tank 3 through the feeding port 31, and then add honey and water into the stirring rod 4, but do not fill it up. The one-way valve formed by the valve plate 49 and the retaining sleeve 47 can fill the stirring rod 4 with liquid but cannot drain it, so there is no need to set a sealing cover for the stirring rod 4. Then start the equipment, control the driving motor in the frame 1 to drive the mixing tank 3 to rotate, and use the driving source to drive the stirring rod 4 to rotate. The driving source of the stirring rod 4 in this embodiment is not limited, and a motor can be used. Since the cross-section of the mixing tank 3 is heart-shaped, when the mixing tank 3 is turned over by itself, it will not only turn the feed up and down, but also make the feed flow left and right under the guidance of the inner wall of the mixing tank 3. At the same time, the stirring rod 4 rotates to stir the feed, and the mixing efficiency is high. At the same time, the mixing tank 3 will drive the stirring rod 4 to rotate, and the liquid inside the stirring rod 4 will also turn up and down, and at the stirring rod 4. Under the guidance of the branches, left and right flows will also be generated, and the honey water mixing efficiency is high. At the same time, when the stirring rod 4 drives the piston 42 to flip, the piston 42 will slide up and down along the branches, and the piston 42 will improve the surging effect of the honey water, further improving the mixing efficiency of the honey water. It should be noted that the length of the piston 42 is greater than the length of the bifurcation position of the stirring rod 4, and the piston 42 will not fall from the branches to the lower half of the stirring rod 4. After running for a period of time, the control sleeve 47 slides downward, and the sleeve 47 is away from the liquid adding branch 44. At this time, when the stirring rod 4 flips with the mixing tank 3, the piston 42 will press the honey water out of the liquid adding branch 44 and spray it into the feed. And through the setting of the one-way valve 45, the stirring rod 4 will not inhale air, and the feed will not block the liquid adding branch 44. By flipping the mixing tank 3, the feed and the honey water can be fully mixed, the mixing is uniform, and the structure is compact;

[0035] The present invention utilizes the piston 42 to slide obliquely along the branches of the stirring rod 4 to control the speed of adding honey. The specific control principle is that the stirring rod 4 rotates to give the piston 42 centrifugal force, and the direction of the centrifugal force is horizontal. Since the branches are inclined, the centrifugal force will be divided into pressure perpendicular to the inner wall of the branch and upward pulling force. Therefore, when the rotation speed of the stirring rod 4 is controlled, the speed of adding honey can be controlled, and the application range is wide.

[0036] Embodiment 2, based on the above embodiment, provides a driving structure of a stirring rod 4;

[0037] like Figure 1-Figure 7 As shown, a fixed bevel gear ring 2 is fixedly installed on the inner side of the control frame 1, a support rod 35 is provided on the outer side of the mixing tank 3, a mounting shaft 5 is rotatably installed on the bottom of the support rod 35, a bevel gear 51 is fixedly installed on the outer side of the mounting shaft 5, the bevel gear 51 is meshed with the fixed bevel gear ring 2, and a speed change assembly is provided at the bottom of the mounting shaft 5, which can drive the stirring rod 4 to rotate.

[0038] The rotation of the mixing tank 3 drives the installation shaft 5 to rotate, and the installation shaft 5 drives the bevel gear 51 to rotate relative to the fixed bevel gear ring 2. The bevel gear 51 rotates under the action of the fixed bevel gear ring 2, and the bevel gear 51 drives the installation shaft 5 to rotate. The installation shaft 5 drives the stirring rod 4 to rotate through the speed change assembly. Therefore, no additional motor drive is required, and no wiring is required. There will be no situation where the wires interfere with the rotation of the mixing tank 3, and the speed of the stirring rod 4 can be controlled by the speed change assembly.

[0039] Furthermore, a mounting flange 21 is provided inside the fixed bevel gear ring 2, and the fixed bevel gear ring 2 is fixedly mounted on the inner wall of the control frame 1 through the mounting flange 21, so the mounting is stable.

[0040] Embodiment 3, based on the above embodiment, provides a speed change assembly structure;

[0041] like Figure 3-Figure 7 As shown, the speed change assembly includes an adjusting wheel fixedly mounted at the bottom of the mounting shaft 5, the adjusting wheel is composed of a plurality of adjusting hydraulic cylinders 52 and adjusting pulleys 53, the adjusting hydraulic cylinders 52 are distributed in a ring shape around the mounting shaft 5, and the telescopic end of the adjusting hydraulic cylinder 52 is rotatably mounted with the adjusting pulley 53;

[0042] A transmission pulley 46 is fixedly installed on the outer side of the stirring rod 4, and the transmission pulley 46 is connected to the adjusting wheel through a transmission belt 7. A tensioning assembly is fixedly installed on the outer side of the support rod 35, and the tensioning assembly can automatically tension the transmission belt 7.

[0043] The rotation of the mixing tank 3 drives the installation shaft 5 to rotate, the installation shaft 5 drives the bevel gear 51 to rotate relative to the fixed bevel gear ring 2, the bevel gear 51 rotates under the action of the fixed bevel gear ring 2, the bevel gear 51 drives the installation shaft 5 to rotate, the installation shaft 5 drives the adjusting wheel to rotate, the adjusting wheel drives the driving pulley 46 to rotate through the driving belt 7, and the driving pulley 46 drives the stirring rod 4 to rotate;

[0044] In this embodiment, the hydraulic cylinder 52 is controlled to extend and retract, and the hydraulic cylinder 52 drives the adjusting pulley 53 to extend and retract. The adjusting pulley 53 changes the transmission radius of the adjusting wheel, thereby changing the speed ratio and the speed of the stirring rod 4. Under the action of the tensioning assembly, the transmission belt 7 has a sufficient adjustment length and is always kept taut.

[0045] It should be noted that the speed change assembly provided in this embodiment can adjust the radius of the adjusting wheel before stirring. During mixing, the pipeline between the adjusting hydraulic cylinder 52 and the external hydraulic system is cut off, and the internal hydraulic pressure of the adjusting hydraulic cylinder 52 is stable, and the pipeline will not affect the flipping of the mixing tank 3.

[0046] Embodiment 4, based on the above embodiment, further includes that the transmission belt 7 is a toothed transmission belt, and the transmission is more stable.

[0047] Embodiment 5, based on the above embodiment, provides a tensioning assembly structure;

[0048] like Figure 8 As shown, the tensioning assembly includes a bracket rod 6 fixedly mounted on the support rod 35, a slide rail 61 fixedly mounted at the bottom of the bracket rod 6, two groups of sliders 62 are slidably connected inside the slide rail 61, tensioning springs 63 are arranged between the two groups of sliders 62 and the inner wall of the slide rail 61, a tensioning wheel 64 is rotatably mounted at the bottom of the slider 62, and the two groups of tensioning wheels 64 are respectively located on both sides of the transmission belt 7.

[0049] Under the action of the tensioning spring 63, the tensioning wheel 64 presses the transmission belt 7 inwardly, increasing the contact length between the transmission belt 7 and the transmission pulley 46 and the adjusting wheel, making the tensioning more stable and easy to install.

[0050] Embodiment 6, based on the above embodiment, further includes: a mounting bottom opening 32 is opened at the bottom of the mixing tank 3, the stirring rod 4 can pass through the mounting bottom opening 32, the internal thread of the mounting bottom opening 32 is connected with a mounting plug 33, the stirring rod 4 is rotatably installed in the mounting plug 33, and a rotating bearing 34 is arranged between the stirring rod 4 and the mounting plug 33.

[0051] Through the arrangement of this embodiment, it is convenient to disassemble and assemble the stirring rod 4 from the mixing tank 3, and during subsequent cleaning, the cleaning opening of the mixing tank 3 is large enough, so that cleaning is more convenient.

[0052] Embodiment 7, based on the above embodiment, further includes that threaded holes are opened at the tops of the two branches above the stirring rod 4, the internal threads of the threaded holes are connected with a plugging head 41, and the plugging head 41 is hemispherical in design. Through this design, it is easy to load and unload the piston 42, and it is more convenient to clean the inside of the stirring rod 4.

[0053] Embodiment 8, on the basis of the above embodiment, further includes: a bottom rod 48 is fixedly installed at the bottom of the cross brace, and a plurality of groups of slots are provided on the outer side of the bottom rod 48; a limiting rotary sleeve 411 is installed inside the stirring rod 4, and the limiting rotary sleeve 411 is located below the stop sleeve 47; when the stop sleeve 47 descends to the top of the limiting rotary sleeve 411, the stop sleeve 47 is away from the liquid adding branch pipe 44; a sliding sleeve 412 is installed at the bottom of the stirring rod 4, and a ratchet rod 413 is slidably connected inside the sliding sleeve 412; the ratchet rod 413 can be inserted in the slot; the upper surface of the ratchet rod 413 is inclined, and a retaining spring 414 is provided between the ratchet rod 413 and the sliding sleeve 412.

[0054] The stopper sleeve 47 provided in the first embodiment needs to be manually controlled to rise and fall, which is quite difficult and requires shutdown control. Therefore, through the provision of this embodiment, the mixing tank 3 will drive the stirring rod 4 to rotate, and the liquid inside the stirring rod 4 will also turn up and down, and will also flow left and right under the guidance of the branches of the stirring rod 4, so that the honey water mixing efficiency is high. At the same time, when the stirring rod 4 drives the piston 42 to turn over, the piston 42 will slide up and down along the branches, and the piston 42 will improve the surging effect of the honey water, further improving the mixing efficiency of the honey water, and when the piston 42 descends, it will give downward pressure to the honey water, and the honey water will give downward pressure to the stopper sleeve 47 through the valve plate 49 , the stopper sleeve 47 applies downward pressure to the bottom rod 48, and the bottom rod 48 pushes the ratchet rod 413 away from the slot through the inclined surface of the ratchet rod 413. As the bottom rod 48 descends, the ratchet rod 413 enters the next slot. At this time, the stirring rod 4 drives the piston 42 to flip downward, and no longer applies pressure to the honey water. During the flipping process of the mixing tank 3, the stopper sleeve 47 automatically descends little by little to give the honey water enough mixing time. When the stopper sleeve 47 is away from the liquid adding branch pipe 44, the honey water can be discharged through the liquid adding branch pipe 44, and the stopper sleeve 47 descends to the position of the limit rotary sleeve 411 to prevent the stopper sleeve 47 from continuing to descend and detaching from the stirring rod 4 and affecting the discharge of the honey water.

[0055] Furthermore, the limiting rotary sleeve 411 is threadedly connected to the bottom of the stirring rod 4 , and the sliding sleeve 412 is welded to the bottom of the limiting rotary sleeve 411 .

[0056] By rotating the limiting rotary sleeve 411 out of the stirring rod 4, the stop sleeve 47 can be taken out, which is convenient for disassembly and assembly.

[0057] In summary, the assembly steps of the device of the present invention are:

[0058] 1. Install the mixing tank 3 and the fixed bevel gear ring 2 on the control frame 1;

[0059] 2. Rotate the mounting shaft 5 onto the mounting support rod 35, and adjust the position of the bevel gear 51 to mesh with the fixed bevel gear ring 2;

[0060] 3. Insert the piston 42 into the stirring rod 4, tighten the plugging head 41, then insert the stopper sleeve 47 into the stirring rod 4 from below, and screw in the limiting rotary sleeve 411 to complete the assembly of the stirring rod 4;

[0061] 4. Insert the assembled stirring rod 4 into the mixing tank 3 and fix and seal it with the installation cock 33;

[0062] 5. Fix the drive pulley 46 on the stirring rod 4, and then sleeve the drive belt 7 on the adjusting wheel and the drive pulley 46. After the sleeve connection is completed, install the tensioning assembly on the support rod 35 and tighten the drive belt 7 to complete the equipment assembly.
