The base 10 is mainly used for supporting all parts of the Chinese chestnut opener, a plurality of containing openings suitable for containing Chinese chestnuts are formed in the base 10, and the Chinese chestnuts can be placed in the containing openings to be relatively fixed, so that the opening efficiency and the quality of the Chinese chestnuts are improved. The base 10 is welded to the lower end of the housing by an iron plate 9. The iron sheet 9 is correspondingly provided with a hole corresponding to the accommodating port.
The shell 6 is arranged on the base 10, and the side surface of the shell 6 is provided with an inlet 7 for placing the Chinese chestnut to be boiled on the base 10. Specifically, the bottom of the housing 6 can be fixedly or detachably connected to the base 10, for example, the bottom of the housing 6 can be welded to the base 10, or can be connected to the base 10 by a screw, and preferably, the housing 6 can be detachably connected to the base 10, so that the base 10 can be detached to clean the receiving opening. The putting-in opening 7 can be configured according to the number and position of the receiving openings on the base 10, so that the Chinese chestnut can be conveniently put into and taken out of the receiving openings.
And the top cover 4 is arranged on the shell 6, and the top cover 4 is provided with an opening. The cover 4 can be plugged onto the housing 6 or screwed onto the housing 6.
The main shaft 5 can be vertically and movably arranged on the shell 6, the lower end of the main shaft 5 is positioned in the shell 6, and the upper end of the main shaft 5 extends out of the opening of the top cover 4. The main shaft 5 is mainly used for transmitting force, in particular, the force generated by a lever device above the main shaft is transmitted to the blade 8 so as to break the Chinese chestnut.
And the lever device is arranged at the upper end of the main shaft 5 and comprises a first connecting rod 3 and a second connecting rod. Wherein,
the first link 3 includes a first end pivotally connected to the top cover 4 and a second end, and the first end is rotatable relative to the top cover 4.
The second connecting rod, including head end and tail end, the head end is held the pin joint with the second, and second connecting rod and first connecting rod 3 can rotate relatively promptly. The upper end of the main shaft 5 is pivoted to the middle part of the second connecting rod, the part from the middle part to the tail end of the second connecting rod is formed into a power arm 2, the part from the middle part to the head end of the second connecting rod is formed into a resistance arm 1, and the length of the power arm 2 is greater than that of the resistance arm 1, so that a lever device is formed, the main shaft 5 can be driven to move downwards by applying a downward force to the tail end of the second connecting rod, and the chestnut placed on the base 10 is broken by the blade 8.
Further, power arm 2 can be dismantled and set up on resistance arm 1. Specifically, a screw hole is formed in the resistance arm 1, a thread is correspondingly formed in the power arm 2, and the power arm 2 is fixed to the resistance arm 1 through the thread and the screw hole. A hanging ring 62 is arranged on the shell 6, and the resistance arm 1 can be placed on the hanging ring 62 after being detached. Specifically, the power arm 2 is made into a shape with a smaller threaded end and a larger tail end, and the threaded end of the power arm 2 can be inserted into the hanging ring 62 after the power arm is detached, so that the occupied space of the Chinese chestnut opener is reduced.
The intermediate disk 51 is provided at the lower end of the spindle 5. The main function of the intermediate disk 51 is to connect the main shaft 5 with the plurality of chestnut breaking rods 53 so as to transmit the force of the main shaft 5 to the plurality of chestnut breaking rods 53. Specifically, the intermediate disk member 51 is a circular disk which is movable within the housing 6 following the main shaft 5.
A plurality of chestnut breaking rods 53 are arranged at the bottom of the middle disk 51 at intervals. The chestnut breaking rod 53 is mainly used for connecting the intermediate disk 51 and the blades 8 so as to transmit the force of the intermediate disk 51 to the blades 8, and the aim of opening a plurality of chestnuts by one action is fulfilled. The number of the broken chestnut stems 53 can be determined as desired, for example 4.
And the blade 8 is arranged below the main shaft 5, and the blade 8 vertically moves along with the main shaft 5. Specifically, the blade 8 is provided at the bottom end of each chestnut breaking rod 53, for example, a slot is provided in the chestnut breaking rod 53, and the blade 8 is installed in the slot. Preferably, the blade 8 is a cross-shaped serrated blade 8, preferably an arc-shaped blade 8, the arc of which is similar to the arc of the chestnut shell, e.g. to the sample mean data of the arc of the chestnut shell.
And the limiting piece 63 is arranged at the lower part of the shell 6 and is positioned below the middle disk piece 51, and the limiting piece 63 is provided with a hole for the chestnut breaking rod 53 to extend downwards. The stopper 63 is fixed and does not move. The stopper 63 serves to restrict the downward movement of the intermediate disk 51 and also serves as a support for the spring 52.
The spring 52 is sleeved on the part of the chestnut breaking rod 53 between the middle disk 51 and the limiting sheet 63. When the chestnut breaking rod 53 moves downwards, the spring 52 is gradually compressed, and in a natural state, namely when the chestnut breaking rod 53 is not stressed any more, the spring 52 drives the chestnut breaking rod 53 to move upwards so as to enable the blade 8 to be far away from the accommodating opening. Preferably, the spring 52 drives the chestnut breaking rod 53 to move upwards so that the blade 8 is hidden inside the shell 6, and the injury to the human body can be avoided.
Preferably, an anti-falling device is arranged between the top cover 4 and the shell 6, the anti-falling device comprises an elastic claw 41 and a matched clamping groove 61, the elastic claw 41 is arranged on the top cover 4, and the corresponding clamping groove 61 is arranged on the shell 6; or the elastic claw 41 is arranged on the shell 6, the corresponding clamping groove 61 is arranged on the top cover 4, and the elastic claw 41 is clamped in the clamping groove 61. The number of the elastic claws 41 and the number of the locking grooves 61 can be determined according to the requirement, generally two elastic claws are arranged on the opposite sides respectively, and the anti-falling device can prevent the top cover 4 from falling off due to traction force in the using process.
