[0002] Ball adding machines are widely used in mining production, glass fiber production, cement production and other fields. The existing ball adding machines are either mechanical, which cannot accurately control the amount of balls added; or automatic, which requires power control and has high procurement and maintenance costs. In some production sites, where it is required to use no electricity and accurately control the amount of balls added, the above two methods cannot meet production needs. In order to meet production needs, it is very necessary to design a controllable mechanical ball adding machine. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a controllable mechanical ball adding machine, which solves the problems raised in the background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a controllable mechanical ball adding machine, comprising a bracket and a ball storage box fixedly installed on the top of the bracket, the bottom end of the ball storage box is fixedly connected to a first connecting tube, the two sides of the bracket are respectively fixedly connected to a first cross bar and a second cross bar, a retractable second connecting tube is provided below the first connecting tube, a pushing and resetting mechanism matched with the second connecting tube is installed between the first cross bar and the second cross bar, a matching lifting and unloading mechanism is provided below the second connecting tube, a lever pushing mechanism matched with the pushing and resetting mechanism is installed on one side of the outer surface of the bracket, and a mechanical pushing mechanism matched with the pushing and resetting mechanism is installed on one side of the outer surface of the bracket;

[0005] The lifting and unloading mechanism comprises a third connecting pipe located at the bottom of the second connecting pipe;

[0006] The second connecting pipe includes a main pipe and a secondary pipe slidably connected to the outside of the main pipe. The bottom end of the first connecting pipe, the top and bottom end of the second connecting pipe and the top end of the third connecting pipe are all beveled, which can prevent the ball from getting stuck.

[0007] Preferably, the pushing and resetting mechanism includes a rectangular rod that passes through and is slidably connected to the outer surface of the first cross bar, the outer surface of the rectangular rod is provided with arcuate surfaces all around, the arcuate surfaces are provided with threaded grooves, the outer surface of the rectangular rod is symmetrically threaded with two adjusting nuts through the threaded grooves, one end of the rectangular rod is fixedly connected to a U-shaped plate, one end of the U-shaped plate is fixedly connected to a connecting plate, the two sides of the main pipe are respectively symmetrically fixedly connected with a first connecting frame and a second connecting frame, the outer surfaces of the connecting plate and the first connecting frame are symmetrically fixedly connected with two limit sleeves, and a spring is embedded and installed between the two opposite limit sleeves.

[0008] Through the above technical solution, the length of the rectangular rod can be changed by rotating the adjustment thread, so that the elastic force of the spring can be changed according to the usage, which is convenient for adjustment. Moreover, since both ends of the spring are limited by the limit sleeve, it is easy to disassemble and replace.

[0009] Preferably, a push rod slidably connected to the outer surface of the second cross bar is passed through the outer surface of the second connecting frame, a pin is slidably connected to the outer surface of one end of the push rod, and a locking knob in contact with the pin is threadedly connected to the outer surface of the push rod.

[0010] Through the above technical solution, when not pushed, the bottom end of the first connecting tube at the top is connected to the top end of the second connecting tube, and the bottom end of the second connecting tube is not connected to the top end of the third connecting tube. At this time, the steel balls in the ball storage box will first fall into the second connecting tube, and the number is certain. At this time, pushing the push rod can drive the second connecting tube to move, so that the bottom end of the first connecting tube is not connected to the top end of the second connecting tube, and the bottom end of the second connecting tube is connected to the top end of the third connecting tube. At this time, the steel balls in the second connecting tube will fall into the third connecting tube. After the push rod loses thrust, the second connecting tube will automatically reset under the action of the spring, and then the steel balls continue to fall into the second connecting tube in a quantitative manner. Repeating the above operation can achieve the operation of quantitative ball drop.

[0011] Preferably, the lever pushing mechanism comprises a rotating shaft fixedly connected to the inside of the bracket, the outer surface of the rotating shaft is rotatably connected to a handle, and the outer surface of the handle is provided with a sliding groove matching with the pin shaft.

[0014] Through the above technical solution, when electricity is available, one end of the shaft pin is moved to the side close to the cam, and then the second screw rod is rotated to move the cam to a position matching the shaft pin. At this time, starting the motor can drive the cam to rotate, which makes it easier to push the push rod through the shaft pin. Through the two driving methods, the ball adding machine can adapt to different usage conditions, thereby improving practicality.

[0016] Through the above technical solution, when it is necessary to adjust the number of steel balls added each time, it is only necessary to rotate the first screw rod, and the first connecting rod can be driven up and down through the thread. The second connecting rod and the moving rod can drive the auxiliary pipe and the third connecting pipe to rise and fall synchronously, and then the length of the second connecting pipe can be changed, so that different numbers of steel balls can be accommodated, which makes it easier to adjust the number of steel balls added each time.

[0017] The present invention provides a controllable mechanical ball adding machine. It has the following beneficial effects:

The pushing and resetting mechanism can drive the connecting tube to move back and forth, and the lifting and unloading mechanism can drive the second connecting tube to extend and retract. It can not only add a quantitative amount of steel balls each time, but also change the amount of steel balls added each time.

[0019] 2. The controllable amount mechanical ball adding machine, through the arranged lever pushing mechanism and mechanical pushing mechanism, can realize the quantitative addition of steel balls through the lever pushing mechanism to drive the pushing reset mechanism and the second connecting tube to move when electricity is not available, and it is also a labor-saving lever, which can reduce the workload. When electricity is available, the motor can drive the cam to rotate, and then drive the pushing reset mechanism. Through the two driving modes, the ball adding machine can adapt to different usage conditions, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] like Figures 1 to 6 As shown, a controllable amount mechanical ball adding machine comprises a bracket 1 and a ball storage box 2 fixedly mounted on the top of the bracket 1, a first connecting tube 3 is fixedly connected to the bottom end of the ball storage box 2, a first cross bar 4 and a second cross bar 5 are fixedly connected to both sides of the bracket 1, a retractable second connecting tube 6 is provided below the first connecting tube 3, the second connecting tube 6 comprises a main tube 61 and a sub-tube 62 slidably connected to the outside of the main tube 61, the bottom end of the first connecting tube 3, the top and bottom ends of the second connecting tube 6 and the top end of the third connecting tube 81 are all in an oblique shape, and the oblique shape can prevent the ball from getting stuck.

[0032] A push-reset mechanism 7 matched with the second connecting pipe 6 is installed between the first crossbar 4 and the second crossbar 5. The push-reset mechanism 7 includes a rectangular rod 71 that penetrates and slides to the outer surface of the first crossbar 4. The outer surface of the rectangular rod 71 is provided with arc surfaces all around, and the arc surface is provided with thread grooves. The outer surface of the rectangular rod 71 is symmetrically threaded with two adjusting nuts 72 through the thread grooves. One end of the rectangular rod 71 is fixedly connected with a U-shaped plate 73, and one end of the U-shaped plate 73 is fixedly connected with a connecting plate 74. The two sides of the main pipe 61 are symmetrically fixedly connected with a first connecting frame 75 and a second connecting frame 76, respectively. The outer surfaces of the connecting plate 74 and the first connecting frame 75 are symmetrically fixedly connected with two limiting sleeves 77, and a spring 78 is embedded and installed between the two opposite limiting sleeves 77. The outer surface of the second crossbar 5 penetrates and slides to be connected with a push rod 79 that is fixedly connected with the outer surface of the second connecting frame 76, and the outer surface of one end of the push rod 79 penetrates and slides to be connected with a pin shaft 710, and the outer surface of the push rod 79 penetrates and slides to be connected with a locking knob 711 that contacts the pin shaft 710.

[0033] The length of the rectangular rod 71 can be changed by rotating the adjusting thread, so that the elastic force of the spring 78 can be changed according to the usage, which is convenient for adjustment. Moreover, since both ends of the spring 78 are limited by the limiting sleeve 77, it is convenient for disassembly and replacement.

[0034] When not pushed, the bottom end of the first connecting tube 3 at the top is connected to the top end of the second connecting tube 6, while the bottom end of the second connecting tube 6 is not connected to the top end of the third connecting tube 81. At this time, the steel balls in the ball storage box 2 will first fall into the second connecting tube 6, and the number is certain. At this time, pushing the push rod 79 can drive the second connecting tube 6 to move, so that the bottom end of the first connecting tube 3 is not connected to the top end of the second connecting tube 6, and the bottom end of the second connecting tube 6 is connected to the top end of the third connecting tube 81. At this time, the steel balls in the second connecting tube 6 will fall into the third connecting tube 81. After the push rod 79 loses its thrust, the second connecting tube 6 will automatically reset under the action of the spring 78, and then the steel balls continue to fall into the second connecting tube 6 in a quantitative manner. Repeating the above operation can achieve the operation of quantitative ball placement.

[0035] Embodiment 2:

[0036] like Figures 1 to 7As shown, a matching lifting and unloading mechanism 8 is provided below the second connecting tube 6, and the lifting and unloading mechanism 8 includes a third connecting tube 81 located at the bottom of the second connecting tube 6. The lifting and unloading mechanism 8 also includes a transverse plate 82 fixedly connected to the inside of the bracket 1, and the upper surface of the transverse plate 82 penetrates the rotating first screw rod 83, and the outer surface of the first screw rod 83 is threadedly connected with a first connecting rod 84, one end of the first connecting rod 84 is fixedly connected to the outer surface of the third connecting tube 81, and the top of the first connecting rod 84 is fixedly connected with a second connecting rod 85, and the top of the second connecting rod 85 penetrates and is slidably connected with a moving rod 86, and one end of the moving rod 86 is fixedly connected to the outer surface of the auxiliary tube 62.

[0037] When it is necessary to adjust the number of steel balls added each time, it is only necessary to rotate the first screw rod 83, and the first connecting rod 84 can be driven to move up and down through the thread. The second connecting rod 85 and the moving rod 86 can drive the auxiliary tube 62 and the third connecting tube 81 to rise and fall synchronously, and then the length of the second connecting tube 6 can be changed to accommodate different numbers of steel balls, thereby facilitating the adjustment of the number of steel balls added each time.

[0038] Embodiment 3:

[0039] like Figures 1 to 8 As shown, a lever pushing mechanism 9 cooperating with the pushing reset mechanism 7 is installed on one side of the outer surface of the bracket 1. The lever pushing mechanism 9 includes a rotating shaft 91 fixedly connected to the inside of the bracket 1. The outer surface of the rotating shaft 91 is rotatably connected to a handle 92. The outer surface of the handle 92 is provided with a slide groove 93 cooperating with the pin shaft 710.

[0040] A mechanical pushing mechanism 10 that cooperates with the pushing and resetting mechanism 7 is installed on one side of the outer surface of the bracket 1.

The outer surface of the second screw rod 101 is threadedly connected to a moving plate 102. A motor 103 is fixedly installed on the upper surface of the moving plate 102. The output shaft of the motor 103 is fixedly connected to a cam 104 that cooperates with the pin shaft 710. A support plate 105 that is slidably connected to the lower surface of the moving plate 102 is fixedly installed on the outer surface of the bracket 1.

[0041] When the lever push mechanism 9 is used, one end of the shaft pin is inserted into the slide groove 93, and then the handle 92 is turned to drive the push rod 79 to move horizontally under the action of the slide groove 93, thereby pushing the push rod 79, and the amount of ball addition can be accurately controlled without electricity.

[0042] When electricity is available, one end of the shaft pin is moved to the side close to the cam 104, and then the second screw rod 101 is rotated to make the cam 104 move to a position matching the shaft pin. At this time, starting the motor 103 can drive the cam 104 to rotate, and then facilitate pushing the push rod 79 through the shaft pin. Through two driving methods, the ball adding machine can adapt to different usage conditions, thereby improving practicality.

[0043] Working principle: when not pushed, the bottom end of the first connecting tube 3 at the top is connected to the top end of the second connecting tube 6, while the bottom end of the second connecting tube 6 is not connected to the top end of the third connecting tube 81. At this time, the steel balls in the ball storage box 2 will first fall into the second connecting tube 6, and the number is certain. At this time, pushing the push rod 79 can drive the second connecting tube 6 to move, so that the bottom end of the first connecting tube 3 is not connected to the top end of the second connecting tube 6, and the bottom end of the second connecting tube 6 is connected to the top end of the third connecting tube 81. At this time, the steel balls in the second connecting tube 6 will fall into the third connecting tube 81. After the push rod 79 loses its thrust, the second connecting tube 6 will automatically reset under the action of the spring 78, and then the steel balls continue to fall into the second connecting tube 6 quantitatively. Repeating the above operation can achieve the operation of quantitative ball placement.

[0044] When the lever push mechanism 9 is used, one end of the shaft pin is inserted into the slide groove 93, and then the handle 92 is turned to drive the push rod 79 to move horizontally under the action of the slide groove 93, thereby pushing the push rod 79, and the amount of ball addition can be accurately controlled without electricity.

[0045] When electricity is available, one end of the shaft pin is moved to the side close to the cam 104, and then the second screw rod 101 is rotated to make the cam 104 move to a position matching the shaft pin. At this time, starting the motor 103 can drive the cam 104 to rotate, and then facilitate pushing the push rod 79 through the shaft pin. Through two driving methods, the ball adding machine can adapt to different usage conditions, thereby improving practicality.
