Detailed Description
The invention is further described with reference to the following figures and embodiments.
As shown in fig. 1, the present invention provides a pineapple shearing apparatus, which comprises a base 1, a shearing assembly 2, a driving member 3, and a transmission assembly 4, and includes a first shearing member 21 and a second shearing member 22, wherein the first shearing member 21 is disposed on the base 1, the second shearing member 22 is located above the front side of the first shearing member 21, the second shearing member 22 is rotatably connected to the base 1, and the driving member is located between the first shearing member 21 and the second shearing member 22; the transmission assembly 4 is used for connecting the second cutting member 22 and the driving member 3, so as to realize power transmission between the driving member 3 and the second cutting member 22.
As shown in fig. 4, when the pineapple shearing device of the present invention is used, the first shearing member 21 and the second shearing member 22 of the shearing assembly 2 are firstly unfolded, the stem 51 of the pineapple 5 to be sheared is aligned with the front side of the first shearing member 21, then the seat body 1 is pushed to move towards the stem 51, at this time, the stem 51 contacts the driving member 3 and applies a force to the driving member 3 to drive the transmission assembly 4 to move, and the transmission assembly 4 moves to drive the second shearing member 22 to rotate, and during the movement, due to the action force of the stem 51, the second shearing member 22 accelerates to move towards the first shearing member 21, and both finally form a shearing force to break the pineapple 5 from the stem 51. Because the pineapple shearing device adopted in the prior art firstly needs to apply a pushing force to lock the stem, and then pulls back to shear the pineapple from the stem, the structure needs to be pushed and pulled firstly, for an operator, the operation steps are more, the operation is inconvenient, time and labor are wasted, and the picking efficiency is low. And here only exert a thrust, can realize forming the shearing force between first shearing piece and the second shearing piece, relative to some shearing mechanism that need two hands to promote two shearing pieces respectively in the prior art, the action is simple, convenient operation.
As shown in fig. 1 and 2, in a further embodiment of the invention: drive assembly 4 includes first transmission piece 41 and second transmission piece 42, first transmission piece 41 is the step-up gear subassembly, the step-up gear subassembly rotates to be connected on the pedestal 1, the step-up gear subassembly is provided with power input end 411, power take off end 412, second transmission piece 42 is connected respectively power input end 411 with driving piece 3 is used for realizing driving piece 3 with power transmission between the power input end 411, second shearing piece 22 is connected power take off end 412, the step-up gear subassembly is used for making power take off end 412's rotational speed is greater than power input end 411's rotational speed. The first transmission member 41 adopts a speed-increasing gear assembly, so that the rotating speed of the second shearing member 22 can be further increased, a larger shearing force is formed between the first shearing member 21 and the second shearing member 22, and the pineapple can be easily broken off from the stems.
As shown in fig. 1 and 2, in a further embodiment of the invention: the speed-increasing gear assembly comprises a first gear 413 and a second gear 414, the first gear 413 and the second gear 414 are both connected with the base body 1 in a rotating manner, the first gear 413 is meshed with the second gear 414, the power input end 411 is arranged on the first gear 413, the power output end 412 is arranged on the second gear 414, and the outer diameter of the first gear 413 is larger than that of the second gear 414. Here, a simple gear train is used to increase the rotational speed of the second shearing module 22, which is simple in structure and low in device production cost.
As shown in fig. 3, in a further embodiment of the present invention: the second transmission member 42 includes a ratchet wheel 421 and a pawl 422, the ratchet wheel 422 is connected to the power input end 411, one end of the pawl 422 is rotatably connected to the driving member 3, the other end of the pawl 422 is engaged with the gear teeth of the ratchet wheel 421, and the driving member 3 is rotatably connected to the seat body 1. The structure of the ratchet wheel 421 and the pawl 422 is adopted, when the driving element 3 rotates, force is applied to the ratchet wheel 421 through the pawl 422 to drive the ratchet wheel 421 to rotate, and due to the ingenious design of the structure, under the condition that the swing amplitude of the driving element 3 is small, the ratchet wheel is enabled to have a large rotation amplitude, the rotation speed of the second shearing element 22 is further improved, so that a larger shearing force is formed between the first shearing element 21 and the second shearing element 22, and the pineapple can be broken off from the stem more easily.
As shown in fig. 3, in a further aspect of the invention: the driving piece 3 with be connected with return spring 6 between the pedestal 1, return spring 6 is used for driving piece 3 to rotate the return, the driving piece rotates extremely when first shearing piece 21 department, pawl 422 drops the teeth of a cogwheel of ratchet 421. There is a return spring to return the driving element 3, but because the return spring exists, when the stem pushes the driving element 3 to the first cutting element 21, at this time, the stem cannot continue to apply a pushing force to the driving element 3, at this time, the stem will remain stationary under the action of the return spring, if the ratchet 421 and the pawl 422 do not disengage, the rotation of the ratchet 421 will be hindered, and further the rotation of the second cutting element will be prevented, and the pineapple can not be cut, so when the driving element rotates to the first cutting element 21, the pawl 422 will disengage from the teeth of the ratchet 421, and after disengaging, the ratchet will continue to rotate under inertia, so that the second cutting element will continue to rotate at a high speed, and form a cutting force with the first cutting element.
