Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a drum-type straw mixer. Background Technique

[0002] In the design of traditional straw mixers, a single-drum mixing tank structure is generally adopted, and each mixing tank needs to be equipped with an independent motor to drive its rotation. This design has many limitations, especially in terms of equipment investment, operation convenience, and discharging efficiency.

[0003] First of all, from the perspective of equipment investment, the design of equipping each mixing tank with a motor undoubtedly increases the overall equipment cost. With the expansion of production scale, the demand for the number of mixing tanks also increases, which means that more funds need to be invested in purchasing motors and other related components. This brings higher energy consumption and maintenance costs, which is undoubtedly a heavy burden for production enterprises pursuing economic benefits.

[0004] Finally, in terms of discharging efficiency, traditional mixers also face many challenges. Since the discharging port position of the mixing tank is fixed, and when discharging, it is necessary to accurately rotate the discharging port of the mixing tank to the lower side so that the materials can be discharged smoothly. However, in actual operation, it is necessary to separately control the start, stop, forward and reverse rotation of each motor to achieve the accurate positioning of the discharging port. This not only reduces the discharging efficiency but also increases the labor intensity and time cost of operators. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drum-type straw mixer to solve the problems mentioned in the background technique.

[0006] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A drum - type straw mixer, comprising a base. A plurality of drum - type mixing tanks are installed on the upper side of the base. A rotating shaft is horizontally fixed in the middle of each drum - type mixing tank. The rotating shaft is rotatably connected to the base. A left friction disk concentrically fixed with the rotating shaft is rotatably arranged on the right side of each rotating shaft. A right friction disk matching the left friction disk is arranged on the right side of the left friction disk. A control disk is fixed on the right side of the right friction disk. A sliding rod is fixed on the right side of the control disk. A limiting block is fixed on the outer side of the sliding rod. A sleeve matching the sliding rod and the limiting block is slidably sleeved on the right side of the limiting block. The sleeve is rotatably connected to the base. A top plate is concentrically fixed on the left side of the sleeve. A tension spring is installed between the top plate and the control disk. A control groove is formed in the middle of the control disk. A rocker hinged to the base left - and - right is installed on the lower side of the control disk. A control wheel matching the control groove is horizontally rotatably connected to the rear side of the rocker. A fixing assembly for fixing the position of the rocker is arranged on the front side of the base. An upper sprocket is concentrically fixed in the middle of the sleeve. A rotating rod is rotatably installed on the lower side of the base. A plurality of lower sprockets matching the upper sprocket are concentrically fixed on the upper side of the rotating rod. A chain is installed between the upper sprocket and the lower sprocket. A power motor drivingly connected to the rotating rod is fixed on the left side of the base.

[0008] The fixing assembly includes an arc - shaped plate fixed to the base. Fixed teeth are evenly spaced and installed on the front side of the arc - shaped plate. Inclined surfaces are arranged on the right sides of the fixed teeth. A handle sleeve is slidably connected to the front side of the rocker in the front - and - rear direction. A fixing rod matching the fixed teeth is fixed to the rear side of the handle sleeve. A return spring fixed to the rocker is installed on the front side of the handle sleeve.

[0009] A limiting plate is fixed to the lower side of each drum - type mixing tank. An adjusting plate connected to the base is arranged on the right side of each limiting plate. A limiting frame matching the front and rear sides of the limiting plate is hinged to the upper side of the adjusting plate left - and - right. A handrail is fixed to the front side of the limiting frame.

[0010] A sliding rail facing the front - and - rear is installed between the adjusting plate and the base. The adjusting plate is slidably connected to the sliding rail in the front - and - rear direction. A crankshaft rod rotatably connected to the base is installed on the rear side of the sliding rail. A connecting rod is hinged to the bottom of the adjusting plate. The other end of the connecting rod is rotatably connected to an eccentric end of the crankshaft rod. The crankshaft rods are drivingly connected by a transmission rod. A stepping motor drivingly connected to the left - hand crankshaft rod is fixed to the upper side of the base.

[0011] Support blocks matching the limiting frame are fixed to the left and right sides of the front part of the adjusting plate.

[0012] Through the combined design of a friction disc and a chain drive, the mixing equipment avoids the need to equip each mixing tank with an individual motor, greatly reducing the equipment cost and energy consumption. At the same time, the structure is relatively simple, the connection and transmission methods between components are clear, facilitating daily maintenance and troubleshooting. Moreover, users can adjust the position of the control panel by rocking the rocker, thereby controlling the rotation speed and stop of the drum-type mixing tank, making the operation simple and intuitive, reducing the operation difficulty of the staff. At the same time, it is also more convenient to adjust the drum-type mixing tank to be vertical, facilitating the addition of materials and discharging of different drum-type mixing tanks during large-scale production. Meanwhile, through modular design, the number of mixing tanks can be conveniently increased or decreased to meet production requirements of different scales. The cooperation of the arc plate, fixed teeth, inclined plane, and fixed rod enables the entire rocker to be fixed by simply moving the handle sleeve to the left. By simply pulling the handle sleeve forward, the fixed rod will release the fixed teeth, and at this time, the rocker can be rotated to the right, thereby controlling the rotation and stop of the drum-type mixing tank. Such a setting makes the fixing component simple and reliable while also making the operation of the fixing component simple, further improving the overall usability of the equipment. When the drum-type mixing tank does not need to rotate, the armrest can be pulled to the left. At this time, the limit frame can frame the limit plate to fix the drum-type mixing tank, facilitating operations such as adding materials and discharging materials inside the drum-type mixing roller by the staff, improving the stability of the drum-type mixing tank during use. There is a certain gap between the front and back of the limit frame and the limit plate. The fixed plate is slidably arranged front and back and is combined with the crankshaft rod and the connecting rod, enabling the stepping motor to drive the front and back shaking of the lower side of the drum-type mixing tank when it works, thereby improving the discharging efficiency when the mixer discharges materials. The stepping motor enables accurate resetting of the fixed plate when not in use, improving the operating reliability of the limit frame. The support blocks on both the left and right sides can limit and support the rotational positions on both sides of the limit frame, preventing the limit frame from accidentally rotating when the fixed plate moves back and forth, improving the operating stability and reliability of the mixer.

Specific embodiments

[0021] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] As Figure 1-6 shown, a drum-type straw mixer includes a base 1, and a plurality of drum-type mixing tanks 2 are installed on the upper side of the base 1. A rotating shaft 3 is horizontally fixed in the middle of each drum-type mixing tank 2. The rotating shaft 3 is rotatably connected to the base 1. A left friction disc 4 concentrically fixed with the rotating shaft 3 is rotated on the right side of each rotating shaft 3. A right friction disc 5 matching the left friction disc 4 is arranged on the right side of the left friction disc 4. A control disc 6 is fixed on the right side of the right friction disc 5. A sliding rod 7 is fixed on the right side of the control disc 6. A limit block 8 is fixed on the outer side of the sliding rod 7. A sleeve 9 matching the sliding rod 7 and the limit block 8 is slidably sleeved on the right side of the sliding rod 7. The sleeve 9 is rotatably connected to the base 1. A top plate 10 is concentrically fixed on the left side of the sleeve 9. A tension spring 11 is installed between the top plate 10 and the control disc 6. A control groove 12 is opened in the middle of the control disc 6. A rocker 13 hinged to the left and right of the base 1 is installed on the lower side of the control disc 6. A control wheel 14 matching the control groove 12 is horizontally rotatably connected to the rear side of the rocker 13. A fixing component for fixing the position of the rocker 13 is arranged on the front side of the base 1. An upper sprocket 15 is concentrically fixed in the middle of the sleeve 9. A rotating rod 16 is rotatably installed on the lower side of the base 1. A plurality of lower sprockets 17 matching the upper sprocket 15 are concentrically fixed on the upper side of the rotating rod 16. A chain 18 is installed between the upper sprocket 15 and the lower sprocket 17. A power motor 19 drivingly connected to the rotating rod 16 is fixed on the left side of the base 1.

[0023] When the device is in use, raw materials such as straw that need to be mixed are placed inside the drum - type mixing tank 2. The cooperation of the power motor 19, the rotating rod 16, the lower sprocket 17, the chain 18 and the upper sprocket 15 enables the power motor 19 to synchronously drive multiple sleeves 9. When no external force is applied, the tension spring 11 makes the left friction disc 4 abut against the right friction disc 5. At this time, the drum - type mixing tank 2 rotates back and forth. When the drum - type mixing tank 2 therein does not need to rotate, turn the rocker 13 to the left. At this time, the cooperation of the control wheel 14 and the control groove 12 makes the right friction disc 5 separate from the left friction disc 4. At this time, the drum - type mixing tank 2 at the corresponding position stops rotating, and the fixing component can fix the rocker 13.

[0024] Through the combined design of the friction disc and the chain drive, the mixing equipment avoids equipping each mixing tank with a separate motor, greatly reducing the equipment cost and energy consumption. At the same time, the structure is relatively simple, the connection and transmission methods between components are clear, which is convenient for daily maintenance and troubleshooting. And users can adjust the position of the control disc 6 by rocking the rocker 13, thereby controlling the rotation speed and stop of the drum - type mixing tank 2, making the operation simple and intuitive, reducing the operation difficulty of the staff. At the same time, it is more convenient to adjust the drum - type mixing tank 2 to be vertical, which is convenient for adding materials and discharging materials to different drum - type mixing tanks during large - scale production. At the same time, through the modular design, the number of mixing tanks can be conveniently increased or decreased to meet the production requirements of different scales.

[0025] The fixing component includes an arc - shaped plate 20 fixed to the base 1. Fixed teeth 21 are evenly spaced and installed on the front side of the arc - shaped plate 20. Bevels 22 are provided on the right side of each fixed tooth 21. A handle sleeve 23 is slidably connected to the front side of the rocker 13 in the front - to - back direction. A fixing rod 24 that matches the fixed teeth 21 is fixed to the rear side of the handle sleeve 23. A return spring 25 fixed to the rocker 13 is installed on the front side of the handle sleeve 23.

[0026] The cooperation of the arc - shaped plate 20, the fixed teeth 21, the bevels 22 and the fixing rod 24 enables the entire rocker 13 to be fixed only by moving the handle sleeve 23 to the left. Only by pulling the handle sleeve 23 forward, the fixing rod 24 will release the fixed teeth 21. At this time, the rocker 13 can be rotated to the right, so as to control the rotation and stop of the drum - type mixing tank 2. Such a setting makes the structure of the fixing component simple and reliable, and at the same time makes the operation of the fixing component simple, further improving the overall usability of the equipment.

[0027] A limiting plate 26 is fixed to the lower side of each drum - type mixing tank 2. A fixing plate 27 connected to the base 1 is provided on the right side of each limiting plate 26. A limiting frame 28 that matches the front and rear sides of the limiting plate 26 is hinged to the upper side of the fixing plate 27 in the left - to - right direction. A handrail 29 is fixed to the front side of the limiting frame 28.

[0028] When the rotary drum mixing tank 2 does not need to rotate, the armrest 29 can be pulled to the left. At this time, the limit frame 28 can frame the limit plate 26 to fix the rotary drum mixing tank 2, so as to facilitate the staff to add and discharge materials inside the rotary drum mixing roller, etc., and improve the stability of the rotary drum mixing tank 2 during use.

[0029] A front-to-back facing slide rail 30 is installed between the fixed plate 27 and the base 1. The fixed plate 27 is slidably connected to the slide rail 30 in the front and back directions. A crankshaft rod 31 rotatably connected to the base 1 is installed at the rear side of the slide rail 30. A connecting rod 32 is hinged to the bottom of the fixed plate 27. The other end of the connecting rod 32 is rotatably connected to an eccentric end of the crankshaft rod 31. A transmission rod 33 is connected between different crankshaft rods 31. A stepping motor 34 drivingly connected to the left crankshaft rod 31 is fixed on the upper side of the base 1.

[0030] There is a certain gap between the front and back of the limit frame 28 and the limit plate 26. The fixed plate 27 is slidably arranged in the front and back directions and, in combination with the arrangement of the crankshaft rod 31 and the connecting rod 32, enables the rotary drum mixing tank 2 to swing back and forth at the lower side when the stepping motor 34 works, thereby improving the discharging efficiency of the mixer when discharging. The stepping motor 34 enables the fixed plate 27 to be accurately reset when not in use, improving the running reliability of the limit frame 28.

[0031] Support blocks 35 matching the limit frame 28 are fixed on both the left and right sides of the front part of the fixed plate 27.

[0032] The support blocks 35 on both the left and right sides can limit and support the rotational positions of the left and right sides of the limit frame 28, thereby preventing the limit frame 28 from accidentally rotating when the fixed plate 27 moves back and forth, and improving the running stability and reliability of the mixer.

[0033] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
