Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a feed mixer. Background Technology

[0002] Feed is the food consumed by animals and is the foundation of livestock farming. It is classified in various ways: by raw material source (plant-based, animal-based, mineral-based, and microbial feeds); by nutritional composition (energy, protein, roughage, and feed additives); and by physical form (powder, pellets, etc.). Feed provides animals with nutrition, promotes growth, maintains health, and improves production performance. Processing typically includes raw material pretreatment, ingredient mixing, pelleting, drying and cooling, and packaging and storage. Formula design must adhere to scientific, economical, palatable, safe, and flexible principles. Currently, the feed industry is developing towards green and environmentally friendly practices, precision nutrition, intelligent production, and diversified raw material development, which is of great significance for ensuring animal health and food safety.

[0003] In existing feed mixers, the opening and closing of the mixing chamber discharge port usually adopts a baffle structure, and some use double baffles. For designs that require the coordinated opening and closing of two baffles (such as left and right or front and rear baffles), most use dual drive devices. This makes it difficult to ensure the precise synchronization of the movement of the two baffles, which may lead to problems with poor material discharge. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a feed mixer to solve the problems mentioned in the background art.

[0015] Preferably, the outer side of the inner wall of the arc-shaped storage groove is provided with an arc-shaped side groove, the toothed block is located inside the arc-shaped side groove, and the bottom of the arc-shaped side groove is provided with a notch.

The transmission box three is fixed to the mixing chamber, the shaft four is rotatably connected inside the transmission box three, the gear is fixed to the left end of the shaft four, and one end of the gear extends into the notch and meshes with the gear block.

[0017] Preferably, the worm gear mechanism includes a second transmission box, a second motor, a bidirectional worm, a third shaft, and worm wheels. The second transmission box is fixed to the mixing chamber and is also fixed between the right ends of the third transmission box. The second motor is fixedly installed at the front end of the second transmission box. The bidirectional worm is rotatably connected inside the second transmission box. The output end of the rear of the second motor is connected to the bidirectional worm. There is a pair of third shafts distributed front and back. The third shaft is located below the bidirectional worm and is connected to the inside of the second transmission box by a bearing. The left end of the third shaft is fixed to the right end of the fourth shaft. There is a pair of worm wheels, each fixed outside the third shaft. The worm wheels are symmetrically arranged. The bidirectional worm rotates in the opposite direction due to its transmission connection with the worm wheels.

[0018] Preferably, the dual-shaft transmission mechanism includes a transmission box one, a shaft one, a driven bevel gear, a transmission bevel gear one, a shaft two, and a transmission bevel gear two. The transmission box one is fixed to the mixing chamber. The shaft one is bearing-connected inside the transmission box one.

[0020] The beneficial effects of this utility model are as follows: By driving the bidirectional worm gear of the motor to rotate, two symmetrical worm wheels are driven to rotate synchronously in opposite directions. This drives the gears to rotate, and the two gears rotate synchronously in opposite directions. As the two gears mesh with the teeth on the outer walls of the two arc-shaped baffles, the two arc-shaped baffles move synchronously in opposite directions. This allows the two arc-shaped baffles to move synchronously out of the arc-shaped receiving groove for material blocking or to be received into the arc-shaped receiving groove for material unloading. This achieves precise synchronous opening and closing of the arc-shaped baffles and provides self-locking protection against displacement of the arc-shaped baffles, improving practicality.

[0028] like Figures 1-6 As shown, a feed mixer includes:

[0029] Bracket 1;

[0030] The mixing chamber 3 is fixed inside the bracket 1. The inner wall of the mixing chamber 3 has arc-shaped receiving grooves 32 at both the front and rear ends. Arc-shaped baffles 31 are slidably connected inside the arc-shaped receiving grooves 32. A set of toothed blocks 34 are fixed on the outer wall of the arc-shaped baffles 31. After the two arc-shaped baffles 31 slide out from inside the arc-shaped receiving grooves 32, they can cooperate to perform material blocking work inside the mixing chamber 3. When the two arc-shaped baffles 31 are retracted into the arc-shaped receiving grooves 32, the mixed feed in the mixing chamber 3 can be discharged normally downwards.

[0031] The gear transmission mechanism 9 is installed at both ends of the mixing chamber 3. The gear transmission mechanism 9 is meshed with the tooth block 34. Through the meshing of the gear transmission mechanism 9 with a set of tooth blocks 34, the arc-shaped baffle plate 3 slides in or out along the arc-shaped receiving groove 32.

[0032] The worm gear mechanism 8 installed at the right end of the mixing chamber 3, and the gear transmission mechanism 9 are all connected to the worm gear mechanism 8. Through the worm gear mechanism 8, the two sets of gear transmission mechanisms 9 can be driven to move synchronously in opposite directions, so as to make the two arc-shaped baffles 3 move synchronously in opposite directions.

[0033] Rotate the mixing paddle 7 connected to the front and rear sides inside the mixing chamber 3. After the feed enters the mixing chamber 3, the feed falls onto the arc-shaped baffle 3 and can then be mixed by the mixing paddle 7.

[0034] The dual-shaft transmission mechanism 5 is installed at the left end of the mixing chamber 3. All the mixing paddles 7 are connected to the dual-shaft transmission mechanism 5. Through the dual-shaft transmission mechanism 5, the two mixing paddles 7 can simultaneously mix the feed inside the mixing chamber 3.

[0035] The motor 6 installed on the upper part of the dual-shaft transmission mechanism 5 can drive the dual-shaft transmission mechanism 5.

[0036] And a discharge port 4 is provided at the lower end of the mixing chamber 3, which is used to discharge the mixed feed.

[0037] The mixing chamber 3 is provided with a feed inlet at the upper end, and a platform 2 is fixed at the upper end of the support 1. The lower end of the platform 2 has an opening that is on the same vertical line as the feed inlet. The left side of the platform 2 is an open section, so that a walkway is connected to the left side of the platform 2. This allows feed mill workers to walk on the platform 2 and pour the feed into the opening, so that the feed enters the mixing chamber 3 along the feed inlet.

[0038] The inner wall of the arc-shaped storage groove 32 has an arc-shaped side groove 33. The toothed block 34 is located inside the arc-shaped side groove 33. The bottom of the arc-shaped side groove 33 has a notch 35. The gear transmission mechanism 9 includes a transmission box 91, a shaft 92, and a gear 93. The transmission box 91 is fixed to the mixing chamber 3. The shaft 92 is rotatably connected to the inside of the transmission box 91. The gear 93 is fixed to the left end of the shaft 92. One end of the gear 93 extends into the notch 35 and meshes with the toothed block 34. The worm gear mechanism 8 includes a transmission housing 81, a motor 82, a bidirectional worm 83, a shaft 84, and a worm wheel 85. The transmission housing 81 is fixed to the mixing chamber 3 and is also fixed between the right ends of the transmission housing 81 and the transmission housing 82. The motor 82 is fixedly installed at the front end of the transmission housing 81. The bidirectional worm 83 is rotatably connected inside the transmission housing 81. The output end of the rear of the motor 82 is connected to the bidirectional worm 83. There are two shafts 84 arranged in a front-to-back pattern. The third shaft 84 is located below the bidirectional worm gear 83 and is connected to the transmission box 2 81 by bearings. The left end of the third shaft 84 is fixed to the right end of the fourth shaft 92. There is a pair of worm gears 85, each fixed outside the third shaft 84. The worm gears 85 are symmetrically arranged. The bidirectional worm gear 83 is connected to the worm gears 85 through transmission, causing the worm gears 85 to rotate in the opposite direction. The second motor 82 is connected to an external power supply and a reversing switch. In this way, the second motor 82 drives the bidirectional worm gear 83 to rotate, thereby causing the bidirectional worm gear 83 to drive the two pairs of worm gears 85. The worm gear 85 rotates synchronously in opposite directions. As the worm gear 85 drives the shaft 3 84 to rotate, the shaft 3 84 drives the shaft 4 92 to rotate. In this way, the shaft 4 92 can drive the gear 93 to rotate, and the two gears 93 rotate synchronously in opposite directions. As the two gears 93 mesh with a set of tooth blocks 34 on the outer wall of the two arc-shaped baffles 31 through the notch 35, the two arc-shaped baffles 31 move synchronously in opposite directions. This achieves the synchronous movement of the two arc-shaped baffles 31 out of the arc-shaped receiving groove 32 to stop the material. Figure 4 As shown, or it can be placed inside the arc-shaped storage groove 32 for unloading, such as... Figure 6 As shown, this achieves precise and synchronous opening and closing of the arc-shaped baffle 31, and the self-locking property of the bidirectional worm gear 83 and worm wheel 85 is used to self-lock and prevent displacement of the arc-shaped baffle 31, thus improving its practicality.

[0039] The dual-shaft transmission mechanism 5 includes a transmission housing 51, a shaft 52, a driven bevel gear 53, a transmission bevel gear 54, a shaft 55, and a transmission bevel gear 56. The transmission housing 51 is fixed to the mixing chamber 3. The shaft 52 is bearing-connected inside the transmission housing 51. The driven bevel gear 53 is fixed to the middle of the outside of the shaft 52. The motor 6 is fixedly installed on the upper end of the transmission housing 51. The output end of the motor 6 extends into the transmission housing 51 and is connected to a driving bevel gear 61. The driving bevel gear 61 meshes with the driven bevel gear 53. There is a pair of transmission bevel gears 54, which are respectively fixed on both sides of the outside of the shaft 52. The transmission bevel gear 56 meshes with the shaft 54. Connected to the right side of transmission bevel gear 54, shaft 55 is fixed to the right end of transmission bevel gear 56. The right side of shaft 55 corresponds to the left side of mixing paddle 7. Motor 6 is connected to an external power supply and switch. Motor 6 drives the drive bevel gear 61 to rotate, which in turn drives the driven bevel gear 53 to rotate. The driven bevel gear 53 drives shaft 52 to rotate, and shaft 52 drives the two transmission bevel gears 54 to rotate synchronously. As transmission bevel gears 54 mesh with transmission bevel gear 56, the two transmission bevel gears 56 rotate synchronously. This drives the two shafts 55 to rotate synchronously, thereby driving the two mixing paddles 7 to rotate synchronously, thus improving the efficiency of feed mixing.

[0040] Working principle: Feed mill workers can walk onto platform 2 and pour feed into the inlet, allowing the feed to enter the mixing chamber 3 along the feed inlet. At this time, two arc-shaped baffles 31 slide out from the arc-shaped receiving groove 32, which can cooperate to block the feed inside the mixing chamber 3. Then, motor 6 drives the driving bevel gear 61 to rotate, which drives the driven bevel gear 53 to rotate. The driven bevel gear 53 drives the shaft 52 to rotate, and the shaft 52 drives the two transmission bevel gears 54 to rotate synchronously. As the transmission bevel gears 54 mesh with the transmission bevel gears 56, the two transmission bevel gears 56 rotate synchronously, thus driving the two shafts 55 to rotate synchronously, thereby driving the two mixing chambers. The mixing paddle 7 rotates synchronously to mix the feed. After the feed is mixed, the motor 82 drives the bidirectional worm gear 83 to rotate, which in turn drives two symmetrical worm wheels 85 to rotate synchronously in opposite directions. As the worm wheels 85 drive the shaft 84 to rotate, the shaft 84 drives the shaft 92 to rotate. In this way, the shaft 92 can drive the gear 93 to rotate, and the two gears 93 rotate synchronously in opposite directions. As the two gears 93 mesh with a set of tooth blocks 34 on the outer wall of the two arc-shaped baffles 31 through the notch 35, the two arc-shaped baffles 31 move synchronously in opposite directions. This allows the two arc-shaped baffles 31 to be synchronously collected into the arc-shaped receiving trough 32 for feeding. Finally, the mixed feed is discharged through the discharge port 4.
