Description

Technical Field

[0001] The utility model relates to the technical field of threshers, in particular to a novel European plum thresher. Background Art

[0002] Prunus truncatula is a deciduous shrub of the genus Prunus in the Rosaceae family, 1.5 meters high. The bark is gray-brown, and the twigs are covered with soft hairs; the leaves are alternately round or elliptical-lanceolate; the flowers and leaves bloom at the same time, solitary or coexisting, and the petals are white or pink; the drupes are nearly spherical, bright red or orange-yellow when ripe.

[0003] After the European plum fruit is formed, since it grows on branches and leaves, it needs to be threshed to facilitate subsequent collection. When threshing, a thresher is often needed. However, when the thresher is currently in use, the European plum fruits on the branches and leaves are removed by rollers. At this time, a large number of plum fruits will slide down together. When sliding down, the plum fruits are prone to collision, and their skins are worn, which affects the subsequent quality. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 As shown, a new type of European plum fruit thresher includes a thresher body 1, a discharging hopper 2 is arranged on the left side of the thresher body 1, a screen frame 3 for filtering plums is arranged at the other end of the discharging hopper 2, a dust suction mechanism 17 is arranged below the screen frame 3, a buffer plate 4 is rotatably connected to the front and rear sides of the inner side of the discharging hopper 2, a rotating shaft at the bottom of the buffer plate 4 extends to the bottom of the discharging hopper 2 and is fixed with a gear 8, and a rack plate 7 is meshed between the front and rear gears 8, a motor 5 is arranged at the bottom of the discharging hopper 2, a cam 6 is bolted to the output shaft of the motor 5, a rebound structure 9 for rebounding the rack plate 7 is arranged on the right side of the bottom of the discharging hopper 2, cleaning structures 11 for collecting branches and leaves are arranged on both sides of the thresher body 1, a placing box 13 is arranged on the left side of the thresher body 1 and at the bottom of the screen frame 3, a screening machine 15 is arranged on the left side of the placing box 13, and a conveyor belt 14 for conveying plums is arranged between the screening machine 15 and the placing box 13.

[0023] The rebound structure 9 includes a fixed plate 91, a movable rod 92 and a spring 93. The fixed plate 91 is fixed at the bottom of the discharge hopper 2, one end of the movable rod 92 is fixed to one side of the fixed plate 91, the surface of the movable rod 92 is movably connected to the inside of one end of the rack plate 7, the spring 93 is sleeved on the surface of the movable rod 92, and the two ends of the spring 93 are respectively fixed between the rack plate 7 and the fixed plate 91. In this way, when the rack plate 7 is movably connected to the surface of the movable rod 92, the spring 93 will be squeezed. When the rack plate 7 is not subjected to force, the elastic force of the spring 93 itself can be used to drive the rack plate 7 to return to the starting position.

[0024] The cleaning structure 11 includes a collecting box 111, a jet head 112, a fan 113 and an air blowing pipe 114. The collecting box 111 is fixed on the back of the thresher body 1, the jet head 112 is fixed on the top of the thresher body 1, the fan 113 is arranged on the surface of the thresher body 1, and the two ends of the air blowing pipe 114 are respectively connected with the fan 113 and the jet head 112. In this way, each time the plums are threshed, the fallen leaves generated on the right side of the top of the thresher body 1 can be started by the fan 113 to transmit wind to the jet head 112, thereby blowing the fallen leaves and branches on the top of the thresher body 1 to the rear, and then fall into the inside of the collecting box 111 for collection.

[0025] The top of the collecting box 111 is fixedly connected with a baffle 12, and the baffle 12 is opened toward the front, so that the fallen leaves can be shielded and prevented from falling on the ground at will.

[0026] The surface on the other side of the rack plate 7 is rotatably connected to a plurality of rollers 10, and the surfaces of the rollers 10 are rollingly connected to the cam 6, so that the friction between the cam 6 and the rack plate 7 can be reduced, making it easier to push the rack plate 7.

[0027] Limiting plates 16 for shielding the plums being transported are fixed on both sides of the top of the conveyor belt 14, so as to prevent the plums from falling during transportation.

[0028] Working principle: When in use, the staff will pass the plums through the wheel at the thresher body 1, and then separate the plums from the branches and leaves. The plums will then slide down through the discharge hopper 2, and some of the impurities such as branches and leaves will fall on the right side of the top of the thresher body 1. At this time, the fallen leaves and impurities can be collected and processed by the cleaning structure 11. As the plums slide down, there will be a large impact force. In order to avoid damage to the surface, the motor 5 can be started and the cam 6 can be driven to rotate so that the protruding part of the cam 6 rotates to the right, thereby applying force to the rack plate 7. As the rack plate 7 moves, the two gears 8 will be driven to rotate, and at the same time, the two buffer plates 4 will be driven to deflect to the opposite side, so that the buffer plates 4 can block the fallen plums, thereby reducing the downward impact force. The plums will then fall onto the surface of the conveyor belt 14 and be transported, so that they fall into the screening machine 15 for screening and collection.
