Description
Technical Field
The invention relates to a picker, in particular to a tea-oil tree seed picking rake.
Background
According to data of Ministry of forestry, the planting area of the camellia oleifera in China in 2019 is more than four thousand and five million acres. The camellia oleifera trees grow higher and are mostly planted on high mountains, and camellia oleifera seeds are small and scattered, so that the picking of camellia oleifera seeds is time-consuming and labor-consuming, each person of the slightly higher trees is difficult to pick two hundred jin each day, and the picking cost is too high. In addition, for camellia seeds at high positions, tree climbing and picking are the most commonly adopted method for young people, so that the falling injury event is often caused and is very dangerous. The existing various fruit pickers are not suitable for picking the camellia seeds.

Detailed Description
Example 1: as shown in fig. 1 to 11, the camellia seed picking rake in the embodiment includes rake teeth 1, the gap between the rake teeth 1 is about 2 cm, small branches and leaves can smoothly slide through the gap between the rake teeth 1, the camellia seeds are scraped on the upper portion of the guide rail 4 and automatically slide down along the guide rail 4 into a back basket carried on the back (the small camellia seeds which can slide in the gap generally have no oil and do not need to be picked), a pair of small arms 13 are fixedly connected to the tail end of the rake teeth 1, a pair of small support arms 14 are fixedly connected to the top of the handle sleeve 2, the tail end of each small arm 13 is hinged to the upper end of each small support arm 14 through a small shaft 6, a torsion spring 7 is sleeved on each small shaft 6, two ends of the torsion spring 7 are connected between the rake teeth 1 and the handle sleeve 2, the front end of the rake teeth 1 is rotated upward by the acting force of the torsion spring 7, and a hand brake device 8 for driving the front end of the rake teeth 1 to rotate downward is arranged between the lower portion of. The hand brake device 8 comprises a fixing ring 10 fastened at the lower part of the wood handle 3, a pair of supporting arms 15 fixedly connected on the fixing ring 10, a fixed shaft 12 screwed on the supporting arms 15, a swinging body 9 hinged on the fixed shaft 12, and a steel wire flexible wire 11 connected between the swinging body 9 and the rake teeth 1; the swinging body 9 consists of a circular ring 9a hinged on the fixed shaft 12, a hand brake handle 9c fixedly connected on the circumferential surface of the circular ring 9a, a swinging arm 9f fixedly connected on the circumferential surface of the circular ring 9a and forming an included angle of about 68 degrees with the hand brake handle 9c, a stop block 9n for limiting the rotation range of the rake teeth 1 and fixedly connected on the circumferential surface of the circular ring 9a, and a reinforcing rib 9m fixedly connected between the hand brake handle 9c and the swinging arm 9 f; the tail end of the swing arm 9f is provided with a small round hole 9s, and the lower end of the steel wire flexible wire 11 passes through the small round hole 9s to be connected with the tail end of the swing arm 9 f; when the torsion spring 7 drives the front end of the rake teeth 1 to rotate upwards, so as to drive the circular ring 9a to rotate through the steel wire flexible wire 11, and the stop block 9n is tightly attached to the fixing ring 10, the rake teeth 1 and the wooden handle 3 approximately form an included angle of 140 degrees, and at the moment, the included angle between the hand brake handle 9c and the wooden handle 3 is approximately 45 degrees, so that when a user presses the hand brake handle 9c to be tightly attached to the wooden handle 3, the included angle between the rake teeth 1 and the wooden handle 3 is slightly smaller than 90 degrees. The guide rail 4 may be made of cloth cut from old clothes and fastened by a support frame 5a fixed to the grip cover 2, a support frame 5c fastened to the middle of the wood handle 3, and a support frame 5e fastened to the lower portion of the wood handle 3. As shown in figures 1 and 2, the upper end of the guide rail 4 is tightly attached to the handle sleeve, and the lower end of the guide rail 4 is separated from the wood handle 3 by a proper distance, so that the camellia seeds can not touch the hand gripping the wood handle 3 when sliding out from the lower end of the guide rail 4, and can smoothly fall into a pack basket carried on the back. If the wooden handle 3 is longer, the number of the supporting frames 5 can be increased properly.
The working principle is as follows: when the hand-held wooden handle 3 extends forwards and upwards (the sight of the tea-oil tree seeds above the picking is better than that of the tea-oil tree seeds directly above the picking, the labor is saved, and dust is not easy to fall into eyes), the rake teeth 1 are approximately vertical and upwards, so that the tea-oil tree seeds can smoothly extend into the small branches of the tea-oil tree seeds to be picked, then the hand brake handle 9c is pressed towards the wooden handle 3, the rake teeth 1 downwards rotate to form an angle of about 85 degrees with the wooden handle 3, the tea-oil tree seeds are smoothly scraped at the upper end of the guide rail 4 when the wooden handle 3 is pulled back, and automatically slide along the guide rail 4 in a back basket carried on the back, and the small branches and leaves between the rake teeth 1 can smoothly slide through the gaps between the rake teeth 1.
Example 2: the difference between the embodiment 2 and the embodiment 1 is that the tail end of the rake teeth 1 is fixedly connected with the handle sleeve 2, and the included angle between the rake teeth 1 and the wood handle 3 is about 80-90 degrees. The manual brake device 8 is not arranged in the embodiment, the structure is simpler, the picking efficiency of the camellia seeds which are at the lower part and have lush branches and leaves is extremely high, the labor is saved, and the manual brake device is not suitable for picking the camellia seeds at the higher part.
