DETAILED DESCRIPTION

[0017] See also Figures 2-3 In an embodiment of the utility model, a loader bucket quick tooth changing device includes a main body 1, a base 2 is fixedly connected to the lower side of the main body 1, a discharge trough 3 is provided inside the base 2, a tooth groove 4 for placing shovel teeth 22 and a bucket groove 5 for placing the front side wall of the bucket 21 are provided on the front side surface of the main body 1, the number of the tooth grooves 4 is equal to the number of the shovel teeth 22, the tooth grooves 4 and the bucket grooves 5 are connected to each other, and a downward pressing structure is provided on the top of the main body 1.

[0018] Preferably, the downward pressing structure includes an upper bracket 6, a front surface of which is provided with a tooth pin placement groove 7, an upper surface of which is installed with a cylinder 8, a driving end of which faces downward and extends to the interior of the upper bracket 6, a pressing plate 9 is fixedly connected to the driving end of the cylinder 8, and a lower surface of the pressing plate 9 is equidistantly fixed with push rods 13, and the number of push rods 13 is equal to the number of tooth grooves 4.

[0019] Preferably, a pre-release cavity 10 is opened inside the main body 1, the number of the pre-release cavities 10 is equal to the number of tooth grooves 4, and each pre-release cavity 10 is respectively located on the upper side of each tooth groove 4, the lower end of the pre-release cavity 10 is connected with the tooth groove 4, the upper end of the pre-release cavity 10 is connected with the interior of the upper bracket 6, and each pre-release cavity 10 corresponds to the bottom of each push rod 13, so that all the tooth pins 23 can be pushed out from the bucket 21 or pushed into the bucket 21 at one time.

[0020] Preferably, pin ejection cavities 12 are equidistantly provided inside the main body 1, and each pin ejection cavity 12 is located directly below each pre-placement cavity 10, respectively. The upper end of the pin ejection cavity 12 is connected to the tooth groove 4, and the lower end of the pin ejection cavity 12 is connected to the discharge chute 3, which is used to eject the old tooth pins 23.

[0021] Preferably, the upper end of the pre-release chamber 10 is shaped like a trumpet, which is convenient for placing the tooth pin 23 inside the pre-release chamber 10. The diameter of the pre-release chamber 10 is larger than the diameter of the tooth pin 23, and the inner diameter of the lower section of the pre-release chamber 10 is only slightly larger than the diameter of the tooth pin 23, which is convenient for the tooth pin 23 to be placed vertically in the pre-release chamber 10, and to be extruded by the push rod 13 later. The inner wall of the pre-release chamber 10 is fixed with a rubber ring 11, and the inner diameter of the rubber ring 11 is smaller than the diameter of the tooth pin 23. The diameter of the pin removal chamber 12 is larger than the diameter of the tooth pin 23. When the tooth pin 23 in the pre-release chamber 10 is pushed downward by the push rod 13, it can be squeezed out from the rubber ring 11 and finally installed on the shovel teeth 22 and the bucket 21. The rubber ring 11 can block the lower end of the tooth pin 23 placed in the pre-release chamber 10 to prevent the tooth pin 23 from sliding down by itself.

[0022] Preferably, the diameter of the push rod 13 is smaller than the diameter of the rubber ring 11, so that the push rod 13 can pass directly through the pre-release cavity 10, and the old tooth pin 23 can be pushed out, or the new tooth pin 23 can be pushed from the pre-release cavity 10 into the shovel tooth 22 and the bucket 21, thereby fixing the shovel tooth 22 at the bucket 21.

[0023] The working principle of the utility model is as follows: when replacing the shovel tooth 22 of the bucket 21, it is necessary to first perform the punching, and fit the shovel tooth 22 and the front side wall of the bucket 21 into the tooth groove 4 and the bucket groove 5 respectively, and then control the cylinder 8 to move the pressing plate 9 and the push rod 13 downward, and use the lower end of the push rod 13 to squeeze the tooth pin 23 located in the shovel tooth 22 downward, so that the tooth pin 23 is finally separated from the inside of the bucket 21 and the shovel tooth 22, and the old tooth pin 23 falls from the pin discharge cavity 12 into the discharge chute 3, and then the shovel tooth 22 and the bucket 21 are taken out from the tooth groove 4 and the bucket groove 5 respectively, and the old shovel tooth 2 2 is removed from the bucket 21, and a new shovel tooth 22 is installed at a predetermined position on the front side wall of the bucket 21. Then, the bucket 21 with the new shovel tooth 22 installed is clamped into the tooth groove 4 and the bucket groove 5, and a new tooth pin 23 is placed from the tooth pin placement groove 7 so that the tooth pin 23 is clamped into the inside of the rubber ring 11. Then, after the cylinder 8 is turned on, the push rod 13 is used to press the tooth pin 23 downward, and finally the tooth pin 23 is pressed into the installation hole inside the shovel tooth 22 and the bucket 21, thereby completing the replacement of all the shovel teeth 22. This process is fast, and all the shovel teeth 22 can be replaced at one time, which improves efficiency.
