DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0022] An adjustable blanking device for a jaw crusher, including a housing 1. Support legs 2 are fixedly installed at the four corners of the lower end surface of the housing 1. A feed inlet 3 is provided on the upper side of the housing 1, and a discharge outlet 4 is provided at the lower end of the housing 1. A motor 5 is fixedly installed at the right end of the housing 1. A distribution roller 6 is rotatably connected inside the housing 1. The output shaft of the motor 5 extends into the housing 1 and is fixedly connected to the distribution roller 6. A plurality of quantitative grooves 8 are provided on the outer surface of the distribution roller 6. A cavity 7 is provided in the middle of the distribution roller 6. A communication hole 10 is provided for communicating between the cavity 7 and the quantitative grooves 8. An adjusting plate 9 is slidably connected inside the quantitative grooves 8.

[0023] A sleeve 12 is fixedly installed on the lower side of the left end surface of the housing 1. A piston plate 14 is slidably connected inside the sleeve 12.

[0024] A telescopic rod 13 is provided on the right side of the piston plate 14. The telescopic rod 13 is fixedly connected to the housing 1, and the left end of the telescopic rod 13 is fixedly connected to the piston plate 14.

[0025] Start the motor 5 to make the distribution roller 6 rotate. The falling crushed stones will enter the quantitative grooves 8. When the quantitative grooves 8 are full, the crushed stones will not enter. In this way, the falling crushed stones can be quantitatively processed. As the distribution roller 6 rotates, the crushed stones in the quantitative grooves 8 will be discharged from the discharge outlet 4. When the distribution roller 6 rotates, it will synchronously drive the driving wheel 15 to rotate. The driving wheel 15 drives the striking rod 16 to rotate eccentrically, strike the vibration spring 18, and transmit the vibration force to the vibration plate 17, so that the vibration plate 17 vibrates, thereby preventing the material from accumulating in the feed inlet 3 and affecting the normal operation of the equipment.

[0026] A conveying pipe 11 is provided for communicating between the sleeve 12 and the cavity 7. The conveying pipe 11 is rotatably connected to the distribution roller 6.

[0027] A driving wheel 15 is provided on the left side of the housing 1. The left end of the distribution roller 6 extends outside the housing 1 and is fixedly connected to the driving wheel 15.

[0028] A striking rod 16 is eccentrically installed at the left end of the driving wheel 15. A vibration spring 18 is provided on one side of the striking rod 16. A vibration plate 17 is fixedly installed inside the feed inlet 3. The left end of the vibration plate 17 extends outside and is fixedly connected to the vibration spring 18.

[0029] When it is necessary to adjust the capacity of the metering tank 8 for the material, by starting the telescopic rod 13, the piston plate 14 squeezes or expands the gas inside the sleeve 12. The sleeve 12 sucks or discharges air from the metering tank 8 through the delivery pipe 11 and the communication hole 10, so that the adjusting plate 9 rises or falls in the metering tank 8, and thus the purpose of adjusting the capacity is achieved.

[0030] By providing the metering tank 8 and the adjusting plate 9, the utility model quantitatively processes the falling crushed stones in the metering tank 8 to prevent excessive falling of the crushed stones. The adjusting plate 9 adjusts the volume of the metering tank 8, thereby increasing the practicability of the equipment.

[0031] Working principle: Start the motor 5 to rotate the distributing roller 6. The falling crushed stones will enter the metering tank 8. When the metering tank 8 is full, the crushed stones will not enter. In this way, the falling crushed stones can be quantitatively processed. As the distributing roller 6 rotates, the crushed stones in the metering tank 8 will be discharged from the discharge port 4. When the distributing roller 6 rotates, it will synchronously drive the driving wheel 15 to rotate. The driving wheel 15 drives the striking rod 16 to rotate eccentrically, strikes the vibration spring 18, and transmits the vibration force to the vibrating plate 17, causing the vibrating plate 17 to vibrate, so as to prevent the material from accumulating in the feed port 3 and affecting the normal operation of the equipment. When it is necessary to adjust the capacity of the metering tank 8 for the material, by starting the telescopic rod 13, the piston plate 14 squeezes or expands the gas inside the sleeve 12. The sleeve 12 sucks or discharges air from the metering tank 8 through the delivery pipe 11 and the communication hole 10, so that the adjusting plate 9 rises or falls in the metering tank 8, and thus the purpose of adjusting the capacity is achieved.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
