Description
TECHNICAL FIELD
[0001] The utility model relates to the field of agricultural machinery, especially to a starting safety mechanism of starter and agricultural machinery. BACKGROUND
[0002] In modern society, agricultural machinery is widely used in agricultural cultivation. The existing agricultural machinery mostly needs to use an auxiliary starter to start the agricultural machinery when starting.
[0003] In the field of small agricultural machinery, the auxiliary starter is mostly installed in a front auxiliary starter installation mode on the market, that is, the auxiliary starter is arranged at the other end of the agricultural machinery relative to the operating handle. However, when the auxiliary starter is damaged, the agricultural machinery cannot continue to be cultivated, and the auxiliary starter needs to be replaced or repaired. Since it is inconvenient to replace and repair the auxiliary starter in some areas, double auxiliary starters are arranged on the agricultural machinery on the market, that is, a second auxiliary starter, referred to as a rear starter, is arranged at the rear of the front auxiliary starter. The rear starter is usually a hand-operated auxiliary starter. Whether it is a front starter or a rear starter, in order to facilitate starting, the starter is directly arranged on the surface of the engine without additional protection.
[0004] The hand-operated auxiliary starter stores energy in a coil spring by hand operation, and releases the potential energy of the coil spring by operating a starting arm to separate from a ratchet to start the engine. For the rear hand-operated auxiliary starter, since the starting arm is exposed at the end of the handle of the agricultural machinery, misoperation often occurs, which causes the agricultural machinery to move when the starting arm is operated, resulting in accidents and affecting the normal operation of the equipment and causing safety hazards to the operator.

DETAILED DESCRIPTION
[0033] The following embodiments of the present invention are provided as inspiration. Through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention. The scope of protection of the present invention is not limited to the contents of the claims and the description.
[0034] With reference to the accompanying drawings, the present invention is further described:
[0035] refer to Figures 1 to 7The safety mechanism of the starter includes a starting arm 110 of the starter, a mounting bracket 200 and a limiting baffle 300. The mounting bracket 200 is mounted on the engine body and includes a mounting lug 230 which protrudes towards the starting arm 110. The limiting baffle 300 is rotatably connected with the mounting lug 230 and is perpendicular to the axial direction of the starting arm 110. The mounting bracket 200 can be directly mounted on the engine body, the gearbox body 600, the auxiliary starter 100 body or other positions of the agricultural machinery, and the main purpose is to mount the limiting baffle 300. The limiting baffle 300 is mounted on the mounting lug 230 of the mounting bracket 200. When the starting arm 110 of the auxiliary starter 100 needs to be operated in the working state, the limiting baffle 300 is rotatable on the mounting lug 230, and the position where the limiting baffle 300 is mounted is on the axial extension line of the starting arm 110. When the starting arm 110 needs to be operated, the limiting baffle 300 is rotated to expose the starting arm 110, and the starting arm 110 is actuated by the rocker to start the engine and further start the agricultural machinery. When the starting arm 110 does not need to be operated, the limiting baffle 300 blocks the starting arm 110, so that the starting arm 110 cannot be operated, thereby improving the safety of the product.
[0036] The mounting bracket 200 includes a bracket body 210 which is connected with the mounting lug 230 through an extension part 220. The bracket body 210, the extension part 220 and the mounting lug 230 can be integrally formed.
[0037] The bracket body 210 is in a hollow semicircular shape, and mounting parts 240 are arranged at both ends of the bracket body 210. Mounting holes are arranged on the mounting parts 240, which can be used for directly matching the shell of the auxiliary starter 100. The hollow position is used for placing the ratchet 120, the starting arm 110 and other components of the auxiliary starter 100.
[0038] The bracket body 210 is arranged on the surface of the auxiliary starter 100 in a plane through the extension part 220. The mounting lug 230 is perpendicular to the bracket body 210 and protrudes towards the starting arm 110. The limiting baffle 300 is mounted on the mounting lug 230 and is on the axial extension line of the starting arm 110. The structure is simple and does not affect the installation and use of the auxiliary starter 100. The mounting and dismounting are convenient and the maintenance is facilitated.
[0039] The mounting lug 230 and the limiting baffle 300 are both provided with a rotating shaft hole, and the limiting baffle 300 is connected with the mounting lug 230 through a pin shaft 400.
[0040] In actual farming operation, the starting of the agricultural machine is not the same as the gear position of the agricultural machine and the state of the agricultural machine. When the auxiliary starter 100 is started, if the agricultural machine is not in the neutral state, the agricultural machine will move forward or backward after starting. Therefore, at the moment of starting, improper operation of the gear position of the agricultural machine may cause operation failure, and the operator may have a safety hazard. Therefore, matching the state of the limiting baffle 300 with the gear position of the agricultural machine is a more preferred design scheme.
[0041] Therefore, the top of the limiting baffle 300 is connected with the gear shifting mechanism 500. When the gear position is neutral, the gear shifting mechanism 500 drives the limiting baffle 300 to rotate, and the limiting baffle 300 does not block the starting arm 110, so that the starter can be normally started. When the gear position is not neutral, the gear shifting mechanism 500 drives the limiting baffle 300 to rotate, and the limiting baffle 300 blocks the starting arm 110, so that the starter cannot be normally started. In this way, the safety performance of the equipment is further improved.
[0042] Specifically, the top of the limiting baffle 300 is provided with a connecting hole 310.
[0043] The gear shifting mechanism 500 includes a gear shifting connecting rod 530, a gear shifting arm 520, and a gear shifting arm connecting rod 510.
[0044] One end of the gear shifting connecting rod 530 is connected with the gear position control handle, and the other end is connected with the gear shifting arm 520.
[0045] One end of the gear shifting arm 520 is connected with the gear shifting connecting rod 530, and the other end is connected with the gearbox 600.
[0046] One end of the gear shifting arm connecting rod 510 is connected with the connecting hole 310 at the top of the limiting baffle 300, and the other end is connected with the middle part of the gear shifting arm 520.
[0047] The gear shifting arm 520 is perpendicular to the gear shifting connecting rod 530.
[0048] The gear shifting arm connecting rod 510 is perpendicular to the gear shifting arm 520.
[0049] The user operates the gear shifting connecting rod 530 through the gear shifting handle, the gear shifting connecting rod 530 drives the gear shifting arm 520 to rotate, so as to realize the gear position control of the agricultural machine. At the same time, the gear shifting arm connecting rod 510 is connected with the middle part of the gear shifting arm 520. When the gear shifting arm 520 rotates, the gear shifting arm 520 drives the gear shifting arm connecting rod 510 to move, and the movement of the gear shifting arm connecting rod 510 drives the limiting baffle 300 to rotate. Therefore, the state of the limiting baffle 300 has a relative relationship with the gear position state of the agricultural machine. When it is neutral, the limiting baffle 300 just leaks out the starting arm 110, so that the operator can operate the starting arm 110. When the agricultural machine is in a non-neutral state, the limiting baffle 300 just blocks the starting arm 110, so that the operator cannot operate the starting arm 110.
[0050] The bottom of the limiting baffle 300 is provided with an inner recess, when the agricultural machine is in the neutral state, the starting arm 110 is located at the inner recess, and the operator can use the crank to operate the starting arm 110 through the inner recess.
[0051] It should be noted that the aforementioned "vertical" and "middle" are not absolute positions, but only a description of the positional relationship. In actual design, there can be a certain angle or positional deviation. The selection of the gear position determines the angle of rotation of the gear shifting arm 520, and the angle of rotation of the gear shifting arm 520 determines the angle of rotation of the limiting baffle 300. Therefore, the specific angle and position setting relationship can be adjusted according to the actual size.
