DETAILED DESCRIPTION

[0030] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 7 As shown, a field agricultural rice thresher provided by an embodiment of the utility model comprises: a bracket 1, a threshing bin 2 is arranged on the upper surface of the bracket 1, a feed pipe 7 is arranged on the upper surface of the threshing bin 2, a discharge box 4 is arranged on the lower surface of the threshing bin 2, and a driving mechanism 3 is arranged on one side of the threshing bin 2;

[0032] Specifically, Figures 1 to 3 As shown, when in use, the driving mechanism 3 is started to drive the threshing structure inside the threshing bin 2 to work, and then the rice is put into the threshing bin 2 from the feed pipe 7 for threshing, and the processed particles flow out from the discharge box 4, completing the threshing of the rice. The working principle of the rice thresher in this field is very clear to the staff in this field, and no excessive elaboration is made here.

[0033] Further, the shaking assembly 8 and the filtering assembly 11, the shaking assembly 8 is movably installed inside the discharge box 4, the filtering assembly 11 is detachably installed at the lower end of the shaking assembly 8, and the filtering assembly 11 is located at the outlet end of the discharge box 4;

[0034] Specifically, Figures 1 to 3 As shown, when discharging, the rice particles will first pass through the shaking component 8 and the filtering component 11, and the rice particles will be filtered by the filtering component 11 to screen out the rice particles that are not completely shelled. Then, after the thresher has been working for a period of time, the staff needs to rotate the shaking component 8 to pull and drive one end of the filtering component 11 to shake, so as to avoid the rice particles that are not completely shelled to remain in the discharge box 4 and affect the discharge of the material, thereby facilitating the screening of the rice particles without clogging. At the same time, during the screening, the rate of material discharge can be slowed down to avoid the effect of too fast material discharge speed and easy dust raising, thereby improving the use environment and avoiding damage to the ecological environment.

[0035] Further, the suction component 6 is arranged on the bracket 1, and one end of the suction port of the suction component 6 is arranged corresponding to the filter component 11;

[0036] Specifically, Figures 1 to 3 As shown, during the filtering process, the suction component 6 is simultaneously started to absorb the rice particle shells discharged along with the rice particles, and suck them into the suction component 6 for centralized collection, thereby achieving the effect of convenient centralized processing.

[0037] Further, the shaking assembly 8 includes a driving component 801 and a movable frame 802, one end of the driving component 801 is arranged corresponding to one side of the movable frame 802, both sides of the movable frame 802 are provided with a rotating shaft 804, both sides of the discharge box 4 are provided with through holes, and the rotating shaft 804 is arranged in the through holes;

[0038] Specifically, Figure 3 and Figure 4 As shown, by the design that the rotating shaft 804 is set in the through hole, the movable frame 802 can move in the discharge box 4, so that by rotating the driving component 801, the movable frame 802 can be shaken inside the discharge box 4 to avoid blockage.

[0039] Further, the driving component 801 includes a threaded sleeve 8011 and a screw rod 8012, the threaded sleeve 8011 is arranged at one end of the discharge box 4, the screw rod 8012 is threadedly connected in the threaded sleeve 8011, one end of the screw rod 8012 is arranged corresponding to one side of the movable frame 802, and the other end of the screw rod 8012 is provided with a rotating wheel 8013; multiple groups of return springs 803 are arranged on both sides of the movable frame 802, and one end of the return spring 803 is arranged on the inner wall of the discharge box 4;

[0040] Specifically, Figure 3 As shown, the rotating wheel 8013 is rotated to drive the screw rod 8012 to rotate in the threaded sleeve 8011, and one end of the screw rod 8012 will move forward to provide pressure on the movable frame 802. Then the screw rod 8012 is taken out from the threaded sleeve 8011. At this time, the return spring 803 on the left side of the movable frame 802 is stressed. When the force on the movable frame 802 is released, the return spring 803 will rebound immediately and the return spring 803 on the right side is stressed. In this way, the return spring 803 on the right side is stressed on the return spring 803 on the left side, so that the return springs 803 on the left and right sides cooperate with each other, so that the movable frame 802 will shake for a period of time, so as to avoid blockage and improve the filtering effect.

[0041] Further, the filter assembly 11 includes a first filter plate 1101 and a second filter plate 1102. The first filter plate 1101 is arranged at the discharge port at the lower end of the movable frame 802, and the second filter plate 1102 is arranged at the outlet end of the discharge box 4. Threaded holes are provided on both sides of the second filter plate 1102, and the first limiting bolts 10 are threadedly connected in the threaded holes. During installation, when the second filter plate 1102 is located at the outlet end of the discharge box 4, the first limiting bolts 10 are inserted to connect the filter assembly 11 to the discharge box 4.

[0042] Specifically, Figure 3 and Figure 5 As shown, because the threshed rice particles are the seeds themselves, they are usually denser than the unthreshed rice particles. Therefore, the filter diameter of the first filter plate 1101 is larger than the filter diameter of the second filter plate 1102. The rice particles are filtered twice by two sets of filter plates, the first filter plate 1101 and the second filter plate 1102. The first filter plate 1101 and the second filter plate 1102 are used to filter the rice particles twice. The first filter plate is used to filter out the rice particles that are not completely hulled, and the second filter plate is used to filter out the rice particle shells that are discharged together with the hulled rice particles, so as to improve the filtering effect.

[0043] It should be noted that the distance between the first filter plate 1101 and the second filter plate 1102 is where the shells of rice particles are stored, and one end of the suction component 6 corresponds thereto.

[0045] Specifically, Figure 5 As shown, by providing a rotating member 1104 at the lower end of the support rod 1103, when the movable frame 802 is shaken, the first filter plate 1101 will slide along, so that when the first filter plate 1101 slides, one end of the support rod 1103 will rotate along with it through the cooperation of the rotating member 1104, thereby achieving the situation where there will be no jamming during operation.

[0046] Furthermore, a fixing frame 1105 is provided on the lower surface of the second filter plate 1102. The fixing frame 1105 is hollow, and a guide and discharge pipe 5 is detachably installed on the lower end of the fixing frame 1105.

[0047] Specifically, Figure 1 , Figure 3 and Figure 6 As shown, the design of the guide discharge pipe 5 allows the material discharge direction to be adjusted during the material discharge process, which not only facilitates the installation of the collection container but also avoids the situation of material discharge piling up.

[0048] Furthermore, a docking plate 1106 is provided on the lower surface of the fixing frame 1105, a hole is provided on one side of the docking plate 1106, docking holes 12 are provided on both sides of the diversion discharge pipe 5, and a second limiting bolt 9 is provided between the docking hole 12 and the hole;

[0049] Specifically, Figure 3 , Figure 5 and Figure 6 As shown, the inner side of the guide discharge pipe 5 is connected to the fixed frame 1105 along the two sets of docking plates 1106. When the docking hole 12 coincides with the hole mouth, the second limit bolt 9 is inserted and rotated to fix it, thereby achieving the effect of convenient installation.

[0051] Specifically, Figure 3 and Figure 7 As shown, one end of the suction pipe 603 is inserted into the installation hole. At this time, one end of the suction pipe 603 is located between the first filter plate 1101 and the second filter plate 1102. Then, the suction fan 604 is started to suck the rice particle shells, which flow into the collection box 601 through the suction pipe 603 and fall into the movable box 602, thereby achieving the effect of facilitating the recovery of the rice particle shells. When taking materials, the movable box 602 can be pulled out of the collection box 601.
