Description

Technical Field

[0001] This utility model relates to the field of peanut picking devices, and in particular to a peanut picking device. Background Technology

[0002] A peanut harvesting device is a mechanical device specifically designed to separate peanut pods from peanut plants. This device is designed to improve the efficiency of peanut harvesting, reduce manual labor, and ensure that the quality of the peanut pods is not compromised.

[0003] In the prior art, such as the Chinese utility model patent with publication number 202322197544.9, a peanut harvester capable of sieving soil is disclosed. The structure includes a frame with an outer shell. A roller shaft is rotatably connected to the inner wall of the outer shell, and a roller is mounted on the roller shaft. A soil-sieving box is located in the middle of the frame. It also includes a harvesting mechanism, a first soil-sieving mechanism, and a second soil-sieving mechanism. The outer shell contains a harvesting mechanism that detaches the peanuts from the peanut vines. The bottom of the outer shell has a first soil-sieving mechanism for initial soil sieving, and the soil-sieving box has a second soil-sieving mechanism for further soil sieving. However, this peanut harvester with soil sieving still has the following problems in use:

[0004] 1. Peanuts and peanut vines are screened by vibration. When the vibration is too strong, the material moves too fast and impurities move with the peanuts, making effective screening impossible. When the vibration is too weak, the screening accuracy is improved, but the movement speed is reduced, which leads to material blockage.

[0005] 2. The vibration amplitude of the screen is fixed, which is not convenient to adjust according to the usage conditions, thus limiting its applicability. In addition, it lacks a self-locking structure. Utility Model Content

[0006] To address the problem of inconvenient adjustment of screen vibration amplitude in the prior art, this utility model proposes a peanut harvesting device.

[0007] The technical solution of this utility model is as follows: it includes a fruit-picking body, a roller assembly connected to the top of the fruit-picking body, a connecting frame rotatably connected to one side of the fruit-picking body, a sieve plate connected to the bottom of the connecting frame, a discharge baffle connected to the end of the sieve plate away from the connecting frame, a horizontal plate connected to the side of the fruit-picking body near the sieve plate, an adjustment assembly provided on the horizontal plate, and the bottom of the adjustment assembly connected to the top of the sieve plate.

[0008] Support plates are connected to the top two sides of the sieve plate, and a sliding frame is connected to the top of the support plates. A through sliding groove is provided on the sliding frame. The adjusting component includes a threaded rod and a central rod slidably connected inside the threaded rod. The threaded rod is threaded to a horizontal plate. A sliding block is connected to the bottom of the central rod. Sliding columns are provided on both sides of the sliding block and slidably connected in the sliding groove. An upper baffle is connected to the bottom of the threaded rod, and a lower baffle is connected to the outer wall of the central rod. The upper baffle and the lower baffle are connected by a spring. A top plate is connected to the top of the threaded rod, and an adjusting sleeve is sleeved on the outside of the top plate. The inner ring surface of the adjusting sleeve and the outer ring surface of the top plate are splined together.

[0009] Preferably, a positioning ring is connected to the top of the horizontal plate, a fixing groove is provided on the top of the positioning ring, and a diamond-shaped part is provided at the bottom of the adjusting sleeve for inserting into the fixing groove.

[0010] Preferably, the bottom of the inner ring surface of the adjusting sleeve is provided with a retaining edge, and the retaining edge and the top plate are connected by a spring.

[0011] Preferably, the sliding groove has a recess, and the outer ring surface of the sliding column is connected to an annular boss located in the recess.

[0012] Preferably, the bottom of the fruit-picking body is connected to a motor and a support frame, the output end of the motor is connected to a rotating shaft, and the rotating shaft is connected to the roller inside the roller assembly through a belt pulley transmission assembly.

[0013] Preferably, a cam disk is rotatably connected to the support frame, and the rotating shaft is connected to the cam disk through a belt pulley transmission assembly. A square frame that contacts the cam disk is connected to one side of the sieve plate.

[0014] Preferably, a rotating handle is connected to the top of the adjusting sleeve.

[0015] The advantages of this invention are: easy adjustment of the vibration amplitude of the screen plate, allowing for adjustment of the vibration magnitude according to usage conditions. When the amount of material to be screened is too small or fine screening is required, tightening the threaded rod reduces the vibration amplitude of the screen plate, prolonging the material residence time and improving screening efficiency. When screening a large amount of material, loosening the threaded rod increases the vibration amplitude of the screen plate, accelerating the material movement speed and effectively preventing material accumulation, thus expanding the applicability of the equipment and facilitating vibration amplitude adjustment.

[0016] By setting a positioning ring at the bottom of the adjusting sleeve, the threaded rod is locked, preventing it from loosening due to vibration and improving the stability during screening. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] refer to Figures 1 to 5The system includes a peanut-picking body 101, with a roller assembly 102 connected to its top. Unpicked peanut vines are fed into the roller assembly 102 through an opening on one side. The peanut vines are preferably dried. After picking, the peanut vine debris and peanuts fall onto a sieve plate 104 at the bottom. A fan is also provided on one side of the sieve plate 104 to blow away lighter debris. A connecting frame 103 is rotatably connected to one side of the peanut-picking body 101, and the sieve plate 104 is connected to the bottom of the connecting frame 103. The sieve plate 104 has sieve holes to facilitate the picking of peanuts and peanuts. For impurity screening, the end of the screen plate 104 away from the connecting frame 103 is connected to a discharge baffle 105. The discharge baffle 105 is used to guide the screened peanuts toward the center. The side of the picking body 101 near the screen plate 104 is connected to a horizontal plate 106. An adjustment component 107 is provided on the horizontal plate 106. The adjustment component 107 presses the screen plate 104 downward so that the screen plate 104 is at the bottom, that is, the square frame 130 on one side of the screen plate 104 is pressed on the cam plate 129. The bottom of the adjustment component 107 is connected to the top of the screen plate 104.

[0026] The following provides a structure for adjusting the tightness of the adjusting component 107, which facilitates adjusting the vibration effect of the screen plate 104 according to usage conditions: (Reference) Figure 3 and Figure 4The top two sides of the sieve plate 104 are connected to support plates 108, and the top of the support plates 108 is connected to a sliding frame 109. The sliding frame 109 has a through sliding groove 110. The adjusting component 107 includes a threaded rod 111 and a central rod 112 slidably connected inside the threaded rod 111. When the sieve plate 104 vibrates up and down, the connection position with the central rod 112 will change. The sliding groove 110 is used for sliding to adapt to the connection point. The threaded rod 111 is threadedly connected to the horizontal plate 106. The bottom of the central rod 112 is connected to a sliding block 113. The two sides of the sliding block 113 are provided with sliding columns 114 slidably connected in the sliding groove 110. The sliding columns 114 slide in the sliding groove 110. The threaded rod 111... The bottom of the 11 is connected to an upper baffle 115, and the outer wall of the central rod 112 is connected to a lower baffle 116. The upper baffle 115 and the lower baffle 116 are connected by a spring 117. The spring 117 is in a compressed state. By changing the degree of compression of the spring 117, the vibration amplitude of the screen plate 104 is changed. The top of the threaded rod 111 is connected to a top plate 118. An adjusting sleeve 119 is sleeved on the outside of the top plate 118. The adjusting sleeve 119 and the top plate 118 are splined. By rotating the adjusting sleeve 119, the threaded rod 111 can be rotated, thereby adjusting the position of the threaded rod 111 on the horizontal plate 106. At the same time, the distance between the upper baffle 115 and the lower baffle 116 is also adjusted. The inner ring surface of the adjusting sleeve 119 and the outer ring surface of the top plate 118 are splined.

[0027] Specifically, refer to Figure 3 and Figure 4 The top of the horizontal plate 106 is connected to a positioning ring 120. During use, the threaded rod 111 may rotate due to vibration. The positioning ring 120 can fix the adjusting sleeve 119 to prevent it from becoming loose. The top of the positioning ring 120 is provided with a fixing groove 121, and the bottom of the adjusting sleeve 119 is provided with a rhomboid part 122 for inserting into the fixing groove 121. The adjusting sleeve 119 can be inserted into the fixing groove 121 on the positioning ring 120 through the rhomboid part 122 at the bottom, thereby restricting the rotation of the adjusting sleeve 119.

[0028] Specifically, refer to Figure 3 and Figure 4 The bottom of the inner ring surface of the adjusting sleeve 119 is provided with a retaining edge 123, which serves as a support. The retaining edge 123 and the top plate 118 are connected by a spring 117. The spring 117 is in a compressed state and is used to push the adjusting sleeve 119 to press on the positioning ring 120.

[0029] Specifically, refer to Figure 3The sliding groove 110 has a groove 124. When the sliding column 114 slides in the sliding groove 110, it is easy for it to rotate. The positioning effect of the annular boss 125 on the sliding column 114 in the groove 124 can prevent the sliding column 114 from rotating. The annular boss 125 located in the groove 124 is connected to the outer ring surface of the sliding column 114.

[0030] The following provides a structure for driving the screen plate 104 to vibrate up and down: Specifically, refer to Figure 2 and Figure 5 The bottom of the fruit-picking body 101 is connected to a motor 126 and a support frame 127. The output end of the motor 126 is connected to a rotating shaft 128. The output end of the motor 126 drives the rotating shaft 128 to rotate. The rotating shaft 128 drives the roller assembly 102 and the cam disk 129 to rotate through a belt pulley transmission assembly. The rotating shaft 128 is connected to the roller inside the roller assembly 102 through a belt pulley transmission assembly.

[0031] Specifically, a cam disk 129 is rotatably connected to the support frame 127, for reference. Figure 5 The rotating shaft 128 is connected to the cam disk 129 via a belt pulley transmission assembly. A square frame 130 is connected to one side of the sieve plate 104 and contacts the cam disk 129. The square frame 130 is hollow inside, with only one crossbar in contact with the cam disk 129.

[0032] Specifically, refer to Figure 3 and Figure 4 The top of the adjusting sleeve 119 is connected to a rotating handle 131, which facilitates the rotation of the adjusting sleeve 119 by rotating the handle 131.

[0033] For those skilled in the art, the roller assembly 102 and the fan structure are well-known technologies, so they will not be described in detail.

[0034] Working principle: Unharvested peanut vines are added into the roller assembly 102 through the top feeding port. After passing through the roller assembly 102, they fall onto the bottom screen plate 104. During the descent, a fan blows out lighter debris, preventing it from falling onto the screen plate 104. Some impurities and peanuts fall onto the screen plate 104. The up-and-down vibration of the screen plate 104 drives the peanuts to move, while simultaneously discharging impurities through the screen holes. When the vibration amplitude of the screen plate 104 needs to be adjusted, the adjusting sleeve 119 is pulled upwards. At this time, the adjusting sleeve 119 will disengage from the positioning ring 120. Then, the adjusting sleeve 119 is rotated. At this time, the adjusting sleeve 119 will drive the threaded rod 111 to rotate through the top plate 118. This allows the distance between the upper baffle 115 and the lower baffle 116 to be adjusted, thereby adjusting the tension of the spring 117 and controlling the vibration amplitude of the screen plate 104. When the material to be screened is excessive, the threaded rod 111 can be loosened, reducing the compression of the spring 117. This reduces the vibration amplitude of the screen plate 104 and increases the material movement speed at the top, thus improving the screening capacity. When the material to be screened is insufficient or fine screening is required, the threaded rod 111 can be tightened, increasing the compression of the spring 117 and reducing the vibration amplitude, thereby improving the screening quality.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
