[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-7 The threshing device of a melon thresher shown in the figure comprises a local sieve hole provided at the bottom of the right section of the shell 1 for discharging the seeds after separation, and the peel and pulp are discharged from the discharge port on the right side. When in use, the threshing roller 2 inside the shell 1 is driven by a motor to work, and the threshing roller 2 is provided with a section of auger 3, which transports the fruits and vegetables put into the shell 1 to the right side. The length of the auger 3 is the same as the length of the feed port, and its purpose is to avoid the accumulation of fruits and vegetables at the position of the feed port; a U-shaped scraper frame 4 is provided on the right section of the threshing roller 2, and a connecting plate 6 for strengthening its structure is provided on the scraper frame 4. The connecting plate 6 is made of double-layer manganese steel, and in order to further improve the structural strength and stability of the scraper frame 4, a reinforcing rod 5 is connected between the threshing roller 2 and the scraper frame 4 by welding; the connecting plate 6 and the scraper 7 are installed in a detachable manner.

[0026] The oblong hole provided on the scraper 7 can increase the adjustable amount after bending when the connecting plate 6 and the scraper frame 4 are collided by stones and deformed, thereby enhancing its practicality.

[0027] The connecting plate 6 is provided with a mounting hole 61 and a through hole 62, which are interconnected, and the mounting hole 61 is adapted to the oblong hole, so that the locking pin 9 can be passed through in sequence. During this process, the limit pin 10 is inserted from the through hole 62 at the bottom in advance, and the end of the limit pin 10 is inserted into the mounting hole 61, and the installation cooperation between the limit pin 10 and the locking pin 9 is completed to achieve quick installation and locking.

[0028] In order to achieve rapid installation between the limit pin 10 and the locking pin 9, a T-shaped limit block 101 is provided on the top surface of the limit pin 10, the limit block 101 is located in the installation hole 61, and the bottom section of the limit pin 10 is T-shaped, and a spring is pressed between the limit pin 10 and the connecting plate 6. Under the action of the spring, the limit pin 10 always has a downward thrust. When in use, the slot 91 at the end of the locking pin 9 has a slide groove 92 at its bottom. The slot 91 cooperates with the slide groove 92 and with the limit block 101 to achieve the purpose of plug-in. The arc-shaped limit groove 93 is provided on the inner wall of the slide groove 92. After rotating 90°, the locking task is completed. Through the above-mentioned structure and the spring, the locking pin 9 and the limit pin 10 are coordinated to achieve the purpose of limiting the rubber scraper 7.

[0029] In order to reduce the influence of the locking pin 9 on the scraper 7, when the locking pin 9 is installed and used, a pad 8 is installed between it and the scraper 7 to disperse the pressure so that the pressure generated by the three groups of locking pins 9 is shared by the pad 8.

[0030] The working principle of the utility model is as follows: through the feed port at the top of the shell 1, the threshing roller 2 rotates under the drive of the motor, and the fruits are transported to the right side through the auger 3 on the threshing roller 2, and then the scraper 7 installed on the scraper frame 4 beats the fruits to separate the peel, pulp and seeds, and the seeds are discharged from the sieve holes at the bottom of the shell 1, and the peel and pulp are discharged from the discharge port on the right side, completing the threshing operation.

[0031] When the rubber scraper 7 needs maintenance and replacement, the locking pin 9 is turned so that the locking pin 9 rotates in the mounting hole 61 of the connecting plate 6, and the limit block 101 of the limit pin 10 moves in the limit groove 93. Then the locking pin 9 is stretched outward so that the limit block 101 slides in the slide groove 92 and the slot 91, and finally slides out, so that the locking pin 9 and the limit pin 10 are respectively discharged from the mounting hole 61 and the through hole 62, thereby releasing the connection between the scraper 7 and the connecting plate 6, replacing the new scraper 7, and then performing the reverse operation to complete the installation of the scraper 7.

[0032] During the above operation, in order to reduce the wear on the scraper 7, a pad 8 is placed between the scraper 7 and the locking pin 9 to expand the contact surface between the locking pin 9 and the scraper 7 and reduce the wear.

[0033] The electromechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.

[0034] Components not described in detail herein are prior art.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
