Detailed Implementation
[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.
[0039] This utility model provides a grass seed removal and cleaning vehicle, which has a body 10, as shown in the attached instruction manual. Figure 1 To be continued Figure 13It is known that the system includes: a feeding mechanism 11, a lifting mechanism 30, a bulk grain box 40, an air screen mechanism 50, and a discharge mechanism. The feeding mechanism 11 is mounted on the machine body 10 and has two feeding ports. The first feeding port 12 is connected to the impurity removal mechanism 20 below, and the second feeding port 13 is connected to the lifting mechanism 30. Specifically, the first feeding port 12 is used to add grass seeds with more impurities, and the second feeding port 13 is used to add relatively clean grass seeds or other crop seeds. The impurity removal mechanism 20 includes an impurity removal barrel 21, which is equipped with a deawning stirring paddle 22 for deawning grass seeds. Specifically, the deawning stirring paddle 22 has multiple blades distributed circumferentially, and the blades are adapted to the paddle rod 213 provided on the inner wall of the impurity removal barrel 21, which can fully stir and process the grass seeds and increase the contact area with the grass seeds. The first outlet 211 of the impurity removal barrel 21 is connected to the lifting mechanism 30, and the second outlet 212 is connected to the impurity discharge channel 23. The first outlet 211 is used to convey the deawned grass seeds, and the second outlet 212 is used to convey impurities.
[0040] In addition, according to the instruction manual attached Figure 1-3 It can be seen that the lifting mechanism 30 has a lifting channel 301, the lower end of which is connected to the first outlet 211 and the second feed inlet 13 via an interface 302. A conveyor belt 32 is vertically arranged inside the lifting channel 301, and a lifting hopper 33 is arranged on the conveyor belt 32 for lifting grass seeds. The bulk grain box 40 is located below the discharge port of the lifting channel 301 for dispersing grass seeds. The air screen mechanism 50 has two sets of air screen components 51, which are arranged side by side, and the lower ends of both are connected to the opening 43 on the bottom surface of the bulk grain box 40, and the upper ends are connected to the dust removal system 60. Specifically, grass seeds undergo preliminary screening via the first set of air sieve components 51, followed by secondary screening via the second set of air sieve components 51. This process removes impurities and debris, which are then absorbed into the dust removal system 60 for discharge. The discharge mechanism features an inclined vibrating screening box 71 with three layers of sieve plates 72. The screening box 71 has multiple discharge ports. Grass seeds undergo layer-by-layer screening under the drive of the vibrating motor 74, and grass seeds of different treatment levels are discharged through different discharge ports for easy collection.
[0041] Furthermore, according to the instruction manual appendix Figure 4 It is known that the lifting channel 301 is equipped with two discharge ports, including a first discharge port 303 and a second discharge port 304. The purpose is to disperse the grass seeds, prevent blockage during transportation, reduce transmission efficiency, and lower the equipment failure rate.
[0042] Furthermore, according to the instruction manual appendix Figure 1 , 4As shown in Figure -5, the top of the bulk grain box 40 has two inlets 41, which correspond one-to-one with the two outlets of the lifting channel 301. Since the bulk grain box 40 is in a vibrating state, its inlets 41 and outlets are connected in a nested manner, and a leather barrier is set between them to ensure that the vibration of the bulk grain box 40 does not affect the outlets. Each inlet 41 is equipped with an inverted V-shaped guide plate 42, which is used to disperse and spread the grass seeds entering the bulk grain box 40, thereby increasing the contact area between the grass seeds and the channel and improving the transportation efficiency of the grass seeds.
[0043] Furthermore, according to the instruction manual appendix Figure 1 It is known that the inlet 231 at the upper end of the waste discharge channel 23 is connected to the second outlet 212, and the lower end is provided with a waste discharge port 232. A screw conveyor 24 is rotatably installed inside the waste discharge channel 23. Specifically, the screw conveyor 24 can further process the impurities discharged from the grass seeds and transport them to the waste discharge port 232 for discharge outside the equipment.
[0044] Furthermore, according to the instruction manual appendix Figure 10-11 It is known that each air sieve assembly 51 includes an adjusting plate 52, which is vertically installed on one side of the air sieve channel 511. A transparent glass cover 56 is installed on its outer side. The adjusting plate 52 is divided into upper and lower parts, which are connected by a hinge 54. A wrench 57 is installed at the upper end of the adjusting plate 52, and an adjusting bolt 53 is installed at the lower end, which is used to adjust the size of the air sieve channel 511. Specifically, the adjusting plate 52 is installed inside the housing 55. The adjusting bolt 53 is threadedly connected to the adjusting plate 52 through a long slot 551 provided on the housing 55. Due to the transparent viewing window, the internal air sieve situation can be observed in real time. When the wrench 57 is turned manually and the adjusting bolt 53 is operated, the adjusting plate 52 can be driven to move up and down. The hinge 54 can drive the upper and lower plates to form a ">" shape, thereby increasing the width of the air sieve channel 511, and vice versa, so as to increase the amount of grass seeds sieved and improve the air sieve efficiency.
[0045] Furthermore, according to the instruction manual appendix Figure 1 It is known that both sides of the screening box 71 are equipped with vibration motors 74, which can drive the screening box 71 and the bulk grain box 40 to vibrate and drive the grass seeds to move forward, so that the grass seeds can be processed in subsequent steps.
[0046] Furthermore, according to the instruction manual appendix Figure 2 , 12As shown in section -13, each of the three layers of sieve plates 72 inside the screening box 71 has a partition, and each partition contains a vibrating ball 75. Specifically, each layer of sieve plate 72 has a downwardly inclined discharge channel, which allows grass seeds to be discharged accordingly under vibration. Grass seeds passing through the first layer of sieve plate 72 fall to the first discharge port 731 on both sides of the screening box 71, grass seeds passing through the second layer of sieve plate 72 fall to the second discharge port 732 on both sides of the right side of the screening box 71, and grass seeds passing through the third layer of sieve plate 72 fall to the third discharge port 733 in the middle of the right side of the screening box 71. Workers can collect grass seeds of different treatment levels accordingly, making it highly practical.
[0047] Furthermore, according to the instruction manual appendix Figure 1 As can be seen, all of the above-mentioned moving elements are driven by corresponding motors, and each motor is electrically connected to the controller 61. Some of these motors are shown in the figure. All of them can realize the entire operation of the equipment, which will not be elaborated here.
[0048] Furthermore, according to the instruction manual appendix Figure 2 It can be seen that each discharge port is equipped with an openable baffle 76 to facilitate the operation of staff to discharge materials.
[0049] The grass seed removal and cleaning vehicle provided by this utility model operates as follows:
[0050] Grass seeds to be deawned are added through the first feed inlet 12, while deawned grass seeds or corn and wheat grains are added through the second feed inlet 13. The deawning machine is then used to remove the awns, and impurities are discharged through the auger 24. The grass seeds are lifted through the lifting hopper 33 and then divided into two paths, which are discharged through two outlets and enter the two inlets 41 of the bulk material box, which facilitates diversion and dust removal. Driven by the vibrator, the grass seeds can be spread out and moved forward, and then subjected to air screening. The grass seeds can undergo two air screenings for dust removal. Because a transparent viewing window is provided, the upper air duct can be manually adjusted by turning the lever 57 to adjust the hinge 54, which can control the air duct to narrow or widen. The internal air screening situation can be observed and adjusted in real time. After being screened by air, the grass seeds enter the final screening box 71. Through the screening of three layers of screen plates 72, the first layer of grass seeds is diverted to the first discharge ports 731 on the left and right sides of the screening box 71, the second layer of grass seeds is diverted to the two second discharge ports 732 on the rear side of the screening box 71, and the third layer of grass seeds is diverted to the two third discharge ports 733 in the middle of the rear side of the screening box 71. This achieves automatic diversion and discharge, effectively avoids grass seed accumulation, greatly reduces material blockage, and makes the equipment highly practical and efficient.
