Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a discharging device of a winter melon harvester. Background Art

[0002] Asparagus cochinchinensis, also known as Asparagus cochinchinensis, is an herbal medicine included in the Chinese Pharmacopoeia. It has the effects of nourishing yin and moistening dryness, clearing the lungs and promoting the production of body fluids, and has high medicinal value. The tuberous roots of Asparagus cochinchinensis are relatively developed and can penetrate up to 50 cm deep into the soil. Because Asparagus cochinchinensis was previously dug manually, there was a lack of harvesters specifically for digging Asparagus cochinchinensis. Therefore, special harvesters for harvesting Asparagus cochinchinensis have appeared on the market.

[0026] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1-3An embodiment shown provides a unloading device of an asparagus harvester, including a unloading hopper 1, which is installed at the tail of the asparagus harvester, and the unloading hopper 1 includes an inclined bottom plate 11 and side plates 12 vertically arranged at the edges of both sides of the inclination direction of the bottom plate 11, the end of the bottom plate 11 close to the upper side of the inclination direction is the feed port of the unloading hopper 1, and the end of the bottom plate 11 close to the lower side of the inclination direction is the discharge port of the unloading hopper 1, and the inclination angle of the bottom plate 11 is required to enable the asparagus transported by the asparagus harvester to roll from the feed port to the discharge port; a moving mechanism 2 is arranged below the unloading hopper 1, and the moving mechanism 2 is used to drive the unloading hopper 1 to move when the asparagus harvester moves; a baffle 3 is hinged between the bottom of the two side plates 12 close to the lower side of the inclination direction, and is used to block the discharge port of the unloading hopper 1 to prevent the asparagus from rolling out directly from the discharge port; two drive motors 4 are respectively arranged on the two side plates 12 At one side edge near the baffle 3, its output end is connected to the baffle 3 through a connector 10 and drives the baffle 3 to rotate along the hinge to cover the discharge port of the discharge hopper 1; a height sensor 5 is arranged at the edge of the side panel 12 away from the bottom plate 11 to detect the height of the goods in the discharge hopper 1. The height sensor 5 can use an infrared transmitter and a receiver. When the goods collected in the discharge hopper 1 are high enough to cover the infrared rays emitted by the infrared transmitter, it means that the discharge hopper 1 is full; the corresponding electromagnetic parts 6 and iron parts 7 are arranged, and the iron part 7 is arranged in the middle of the side of the baffle 3 away from the hinge end. The electromagnetic part 6 is arranged on the discharge hopper 1. When powered on, the baffle 3 and the discharge hopper 1 are magnetically connected through the electromagnetic part 6 and the iron part 7; a controller 8 is connected to the drive motor 4, the height sensor 5 and the electromagnetic part 6 by signal.

[0029] The working principle and usage process of this embodiment are as follows:

[0030] The utility model is connected to the tail of the asparagus harvester and is used to collect the asparagus transported by the asparagus harvester. First, the baffle 3 is rotated to completely cover the discharge port of the discharge hopper 1. The asparagus transported by the asparagus harvester will roll from the feed port to the discharge port because the bottom of the discharge hopper 1 is inclined. The baffle 3 will not be pushed away by the rolling asparagus because the electromagnetic part 6 and the iron part 7 are magnetically connected. Those skilled in the art can choose an electromagnetic part 6 with greater suction force to prevent the baffle 3 from being pushed away by the rolling asparagus. The specific model of the electromagnetic part 6 will not be described in detail in this application. When the height sensor 5 detects that the cargo in the discharge hopper 1 is full, it will send a signal to the controller 8. After receiving the signal, the controller 8 will first cut off the power to the electromagnetic component 6, so that the magnetic connection between the iron component 7 and the electromagnetic component 6 disappears. The baffle 3 is pushed open by the gravity of the asparagus accumulated in the discharge hopper 1 to discharge the material. When the staff observes that the unloading is completed, the controller 8 sends a start signal to the drive motor 4 and a power-on signal to the electromagnetic component 6. The drive motor 4 rotates to drive the connecting part 10 to pull up the baffle 3. When the iron component 7 and the electromagnetic component 6 on the baffle 3 are magnetically connected again, the controller 8 sends a stop signal to the drive motor 4, and the baffle 3 covers the discharge port of the discharge hopper 1 again, and the discharge hopper 1 collects and discharges the material for the next time.

[0031] Example 2

[0032] This embodiment is developed on the basis of the above embodiment to solve the problem of screening soil in the discharge hopper 1. Specifically, Figure 1-2 As shown, a number of through holes 9 are provided on the bottom plate 11 and the side plates 12. The asparagus transported to the discharge hopper 1 still has some dirt on it, and this dirt can be sifted out of the discharge hopper 1 through the through holes 9 during the shaking of the discharge hopper 1. In order to facilitate the sifting out of the dirt from the through holes 9, the through holes 9 can also be arranged in a matrix to ensure that there are enough through holes 9 on the bottom plate 11 and the side plates 12. Furthermore, the diameter of the through holes 9 on the bottom plate 11 is larger than that of the through holes 9 on the side plates 12. The dirt on the asparagus falls downwards, so the diameter of the through holes 9 on the bottom plate 11 is larger than that of the through holes 9 on the side plates 12, making it easier for the dirt to be sifted out of the through holes 9 on the bottom plate 11, and some lighter dirt can be sifted out from both sides.

[0033] Example 3

[0034] This embodiment is developed based on the above embodiment to solve the problem of how the driving motor 4 drives the baffle 3 to rotate. Figure 3As shown, the connecting member 10 includes a first connecting rod 101 and a second connecting rod 102, one end of the first connecting rod 101 is fixedly connected to the output end of the driving motor 4, the other end of the first connecting rod 101 is rotatably connected to one end of the second connecting rod 102, and the other end of the second connecting rod 102 is rotatably connected to the baffle 3. After the driving motor 4 is started, it drives the first connecting rod 101 to rotate clockwise, and the clockwise rotation of the first connecting rod 101 drives the second connecting rod 102 to pull the baffle 3 to rotate so that the baffle 3 covers the feed port of the discharge hopper 1.

[0035] Example 4

[0036] This embodiment is developed based on the above embodiment to solve the problem of how to move the discharge hopper 1. Figure 3 As shown, the moving mechanism 2 includes a mounting plate 21 and a moving wheel 22. The upper end of the mounting plate 21 is set on the side plate 12, and the moving wheel 22 is rotatably connected to the lower end of the mounting plate 21. The rotation of the moving wheel 22 drives the discharge hopper 1 to move.

[0037] Example 5

[0038] This embodiment is developed on the basis of the above embodiment to solve the problem of material receiving in the discharge hopper 1. Figure 1-2 As shown, it also includes a receiving plate 13, which is arranged on the side of the bottom plate 11 close to the upper direction of the inclination, and the angle between it and the bottom plate 11 is an obtuse angle. By setting the receiving plate 13, it is more convenient for the asparagus to fall into the discharge hopper 1.

[0039] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
