[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] Please see Figures 1-4 This invention provides a technical solution:

[0034] The white melon seed direct harvester includes a front-mounted melon-picking mechanism and a loading vehicle. The front-mounted melon-picking mechanism is installed at the traveling end of the loading vehicle. The front-mounted melon-picking mechanism consists of a transmission device 1, a baffle 2, a drive wheel set 3, a guide wheel set 4, a guide wheel set 5, a fixed spare plate 6, and a fork tooth 7.

[0035] In this invention, the transmission device 1 can be a track or a chain, etc. If it is a track, the fork tooth 7 directly penetrates the track. If it is a chain, a carrier plate needs to be set between the two chains, and the fork tooth 7 passes through the carrier plate.

[0036] Two baffles 2 are located on the inner sides of both ends of the transmission device 1, forming a drive cavity with the inner side of the transmission device 1; the drive wheel set 3, guide wheel set 4, guide wheel set 5 and fixed plate 6 are all located in the drive cavity;

[0037] The drive wheel assembly 3 is located at the top corner of the drive cavity and is used for transmission connection with the drive mechanism on the loading vehicle;

[0038] The guide wheel group 4 is located at the front corner of the drive cavity and is used to guide the output direction of the transmission device 1.

[0039] The guide wheel assembly 5 is located at the bottom corner of the drive cavity and is used to guide the digging direction of the fork teeth 7;

[0040] The fixed plate 6 is located between the guide wheel assembly 4 and the guide wheel assembly 5 to limit the rotation direction of the fork tooth 7;

[0041] Multiple fork teeth 7 are evenly distributed on the transmission device 1; the inner end of the fork tooth 7 contacts the bottom surface of the fixed plate 6, causing the fork tooth 7 to rotate at an angle after contact; the middle part of the fork tooth 7 is limited to rotation by the through groove on the transmission device 1, so that the rotation angle of the fork tooth 7 is limited to within 90 degrees; the outer end of the fork tooth 7 is inserted into the ground, causing the fork tooth 7 to lift the white gourd from the ground. This invention designs a front-mounted gourd-picking mechanism that mimics manual gourd-picking operation. It uses a loading vehicle to push the front-mounted gourd-picking mechanism to pick up the gourd from the ground. Compared with the traditional manual method of picking up white gourds from the ground, this invention has a compact and reasonable structure, powerful function, and enters the ground at a 45-degree angle, ensuring accurate gourd picking, reducing the breakage rate of white gourds, and is conducive to market promotion.

[0042] Specifically, a hydraulic mechanism for adjusting the ground clearance of the fork 7 is installed between the outer sides of the two baffles 2 and the traveling end of the loading vehicle.

[0043] Furthermore, the drive wheel assembly 3, guide wheel assembly 4, and guide wheel assembly 5 are all composed of axles and track wheels sleeved on both ends of the axles, and the track wheels are meshed with the transmission device 1.

[0044] Furthermore, bushings are fixed at all four corners of the fixed plate 6, and the bushings are fitted onto the wheel axle.

[0045] Furthermore, when the transmission device 1 is working, the bottom surface of the track forms a 30-degree angle with the horizontal line of the ground. By setting the transmission device 1 at a 30-degree angle, it is not only beneficial for the driver to carry out harvesting operations on the slope where white gourds are planted, but also facilitates observation of the operation; moreover, the front guide wheel set 4 helps to avoid collisions with obstacles and reduce the equipment damage rate.

[0046] It is worth noting that the fork tooth 7 includes a fork strip 701 that passes through the through groove. The middle part of the fork strip 701 rotates axially within the through groove via a pin. The inner end of the fork strip 701 is provided with a contact part 702 that contacts the bottom surface of the fixed plate 6. The outer end of the fork strip 701 is provided with a fork tip 703. The outer wall of the extension of the fork strip 701 that extends out of the through groove to the outside is provided with an angle protrusion 704 on the side closer to the transmission device 1. The outer wall of the extension of the fork strip 701 that extends out of the through groove to the outside is provided with a pressure-bearing protrusion 705 on the side farther away from the transmission device 1.

[0047] In addition, the contact part 702 is an expanded ball head. The wear resistance of the expanded ball head helps to extend the service life of the fork tooth 7.

[0048] In addition, the contact part 702 is a pulley. By having the pulley contact the fixed plate 6, the friction between the fork tooth 7 and the fixed plate 6 is reduced, which helps to extend the service life of the fork tooth 7.

[0049] It is worth noting that the angle between the inclined surface of the angle protrusion 704 and the axis of the fork 701 is 15 degrees, and the inclined surface of the angle protrusion 704 is in contact with the surface of the transmission device 1.

[0050] It is worth noting that the pressure-bearing protrusion 705 is perpendicularly connected to the fork 701, and the outer wall of the pressure-bearing protrusion 705 is in contact with the surface of the transmission device 1. For example... Figures 2-3 As shown, during operation, when the fork 7 moves from the guide wheel assembly 4 to the guide wheel assembly 5, the contact portion 702 at the inner end of the fork 7 contacts the fixed plate 6. Under the pressure of the fixed plate 6, the fork 7 rotates relative to the guide wheel assembly 5 until the angle protrusion 704 contacts the bottom surface of the transmission device 1. Since the angle between the inclined surface of the angle protrusion 704 and the axis of the fork 701 is 15 degrees, and the bottom surface of the transmission device 1 forms a 30-degree angle with the horizontal line of the ground, the fork 701 contacts the ground... The angle between the fork and the ground is 45 degrees. The fork 701 is inserted into the ground at a 45-degree angle, which helps to improve the accuracy of picking up the melon and reduce the damage rate of the melon. After the fork 701 picks up the melon, the fork 701 moves from the guide wheel group 5 to the drive wheel group 3. Under the action of gravity, the fork 701 rotates downward until the pressure protrusion 705 contacts the surface of the transmission device 1. At this time, the fork 701 is perpendicular to the surface of the transmission device 1, which helps to improve the support force of the fork 701 and facilitates the subsequent melon picking operation.
