Description

Technical Field

[0001] The invention belongs to the technical field of forest fruit harvesting machinery, and in particular relates to a forest fruit picking and falling fruit collecting device. Background Art

[0002] Fruits are a category that covers a variety of forest fruits and forest products. These products include not only traditional wild fruits, but also cultivated varieties and fruits with regional characteristics. They are widely used in food, medicine, health products and other fields. Common fruits include walnuts, red dates, chestnuts and hawthorns.

[0003] With the development of science and technology, the harvesting of fruits and vegetables has entered the mechanized era. For example, the harvesting equipment commonly used for fruits and vegetables such as walnuts, red dates, chestnuts and hawthorns mainly performs mechanical vibration and shaking of the fruit trees and automatic collection, which makes harvesting convenient and fast. However, the fruits and vegetables collected by this type of harvesting equipment contain impurities such as leaves and branches mixed in the fruits. As a result, in the subsequent processing stage, a special impurity removal process needs to be set up, which increases the processing burden and cost.

[0004] For example, the Chinese patent with the publication number CN117356252B proposes a clamping crown type fruit harvester, which includes a frame, a collection box, a pitching member, a telescopic member, a fruit-carrying cloth, a clamping mechanism and a vibrator. When harvesting fruits, the operator moves the collection box to the vicinity of the fruit tree through the frame, operates the pitching member and the telescopic member, so that the bottom surface of the collection box is close to the ground, and at the same time, the trunk of the fruit tree to be harvested is limited to one side of the collection box, and then the driving machine is started to tighten the two fruit-carrying cloths to form a bucket-shaped collection cavity at the bottom of the fruit tree trunk. Finally, the clamping mechanism and the vibrator are started in turn to complete the vibration of the fruit tree, so that the fruit falls on the fruit-carrying cloth and enters the collection box for harvesting. However, the fruit-carrying cloth cannot screen the impurities such as leaves and branches that fall with the fruit, so that these impurities are mixed in the fruit and enter the collection box along with the bucket-shaped collection cavity formed by the fruit-carrying cloth. It is necessary to further clean the impurities such as leaves and branches from the collected fruit in the subsequent processing, which increases the subsequent impurity removal work link. Another example is a walnut picking vehicle proposed in a Chinese invention patent with publication number CN109362354A. When picking walnuts, the motor of the knocking head is turned on, the knocking head starts to run, and the length of the telescopic rod is adjusted so that it can reach a height near the tree crown. The walnut fruits are knocked down by the knocking head and then accumulated in a storage box through a collecting tube. However, during the knocking process, the fallen leaves and branches will enter the storage box from the collecting tube together with the walnuts, resulting in more impurities being mixed in the walnuts collected in the storage box. In subsequent processing, the collected forest fruits also need to be further cleaned of impurities such as leaves and branches. Summary of the invention

[0050] See also Figures 1 to 5As shown, in order to be able to fully clean up the impurities mixed in the fruits during the fruit harvesting process, the collected fruits are cleaner and time and processes are saved for subsequent processing. This embodiment provides a fruit picking and falling fruit collection device, including a moving body 1, a vibration device and a picking device, the vibration device is installed on the front side of the moving body 1, the picking device 3 is installed on the rear side of the moving body 1, and a collection box 2 is provided on one side of the picking device 3. Preferably, a moving plate in contact with the ground is provided on the rear side of the moving body 1, and a plurality of rollers are arranged on the bottom of the moving plate to reduce friction when moving in contact with the ground. The picking device 3 includes a picking unit, a conveying component 4 and a driving component 5. The picking unit comprises an outer sieve drum 31, an inner sieve drum 32 and a plurality of shovel plates 33. The outer sieve drum 31 is a horizontally arranged tubular structure and has a plurality of feed holes 34 evenly distributed on the side wall. The feed holes 34 are used for the passage of fruits. One end of the outer sieve drum 31 is rotatably connected to the moving body 1, and the other end is preferably closed. A plurality of shovel plates 33 are distributed in a circular array on the circumference of the outer sieve drum 31. The shovel plates 33 are arc-shaped and the arc opening faces one side of the outer sieve drum 31. The inner sieve drum 32 is a semi-enclosed tubular structure with a notch 35. The notch 35 is a through hole opened along the axial direction of the outer sieve drum 31. The notch 35 is opened along the axial direction of the inner sieve drum 32, and is used for the fruits passing through the feed holes 34 to enter the inner sieve drum 32. The inner sieve drum 32 is inserted in the outer sieve drum 31, and one end of the inner sieve drum 32 extends out of the outer sieve drum 31 and is fixed to the moving body 1, and the inner sieve drum 32 is placed at one end of the moving body 1 and connected to the entrance of the collecting box 2, and a plurality of slag discharge holes 36 are evenly distributed on the side wall of the inner sieve drum 32, and the slag discharge holes 36 are used to screen out impurities mixed in the fruit; the conveying component 4 includes a rotating shaft 41 and a spiral blade 42, one end of the rotating shaft 41 is inserted into the inner sieve drum 32 and the two are coaxial, and the other end extends out of the inner sieve drum 32 and is rotatably connected to the moving body 1, and the spiral blade 42 surrounds the rotating shaft 41; the output end of the driving component 5 is respectively connected to the outer sieve drum 31 and the rotating shaft 41, and is used to drive the outer sieve drum 31 and the rotating shaft 41 to rotate.

[0051] Specifically, when harvesting fruits, the mobile body 1 is installed on a tractor or other mobile equipment, and the vibration device is installed on the front side of the mobile body 1 or the mobile equipment. The vibration device is first used to clamp and vibrate the fruit tree so that the fruits fall under the tree. Then, the distance between the mobile body 1 and the ground is adjusted by the lifting structure between the mobile equipment and the mobile body 1 to ensure that the shovel plate 33 located on the lower side is in full contact with the ground. Then, the mobile equipment is started to move slowly while the driving component 5 is started. The driving component 5 drives the outer sieve drum 31 and the rotating shaft 41 to rotate respectively. The rotation of the outer sieve drum 31 drives the shovel plate 33 to rotate. Through the arc structure setting of the shovel plate 33, the shovel plate 33 carries the fruits on the ground to the position of the notch 35 on the inner sieve drum 32 during the process of rotating toward the arc mouth. At this time, the fruits pass through the feeding hole 34 on the outer sieve drum 31 and the notch 35 on the inner sieve drum 32 in sequence to enter the inner sieve drum 32, and then the spiral blade 42 rotates under the drive of the rotating shaft 41 to transport the fruits entering the inner sieve drum 32 to the collecting box 2 for storage. After the picking is completed, the driving assembly 5 is turned off, and the height of the moving body 1 is adjusted so that the shovel plate 33 leaves the ground. In the above-mentioned fruit picking process, the design of the feeding hole 34 on the outer screen drum 31 can effectively prevent larger solid impurities such as branches and some leaves from entering the inner screen drum 32, and then the slag discharge hole 36 on the inner screen drum 32 can be used to further remove the soil blocks or small solid impurities mixed with the fruits into the inner screen drum 32. At the same time, the spiral conveying mode of the spiral blade 42 can be used to repeatedly stir the fruits, fully screen out the impurities in the fruits, and make the fruits cleaner when entering the collection box 2, thereby saving time and effort in picking up the fruits and effectively improving the efficiency of fruit collection.

[0052] Preferably, the inner sieve drum 32 and the outer sieve drum 31 have different models to choose from, and in actual application, they can be replaced and used according to the types of harvested fruits.

[0053] See also Figure 1 and Figure 3 As shown, further, in order to be able to pick up the fruits on the ground more cleanly, generally more than two groups of picking devices can be set. When more than two groups of picking devices are used, in order to save costs and improve the full use of mechanical energy, the two output shafts 52 in two adjacent picking devices can be connected in a sprocket chain manner, so that only one rotating part 51 is needed to realize multiple groups of picking devices working simultaneously. Therefore, after continuous multiple picking on the ground, it can be ensured that the picking is clean enough and easy to use.

[0054] See also Figure 3 and Figure 4As shown, further, in order to realize the rotation of the outer sieve drum 31 and the rotating shaft 41, it is convenient to continuously pick up the fruits on the ground. The driving assembly 5 includes a rotating part 51, two driving gears 53 and two driven gears 54. The rotating part 51 preferably adopts a servo motor 13, and the rotating part 51 is fixed to the side wall of the moving body 1. The two driving gears 53 are respectively fixed on the output shaft 52 of the rotating part 51. For the sake of stability, the two ends of the output shaft 52 are rotatably connected to the side wall of the moving body 1 through bearings, and then the two driving gears 53 are respectively engaged with a driven gear 54, and the two driven gears 54 are respectively fixed on the outer sieve drum 31 and the rotating shaft 41. In this way, when the rotating part 51 is started during use, the rotating part 51 can drive the two driving gears 53 to rotate through the rotation of the output shaft 52, and then the two driving gears 53 respectively realize the rotation of the outer screen drum 31 and the rotating shaft 41 through the meshing driven gears 54, so that the shovel plate 33 is driven to rotate through the rotation of the outer screen drum 31, and the spiral blade 42 can be driven to rotate through the rotating shaft 41, so as to continuously pick up and clean the fruits on the ground.

[0055] See also Figure 2 and Figure 3As shown, further, in order to improve the removal effect of impurities in the fruit, the collected fruit is made cleaner. A first blowing assembly 6 is provided on the outer side of the outer sieve cylinder 31, and the first blowing assembly 6 includes a covering plate 61, a first air pump 62 and a plurality of blowing pipes 64. The covering plate 61 is an arc-shaped structure, and its axis coincides with the axis of the outer sieve cylinder 31. The covering plate 61 is wrapped around the outer side of the outer sieve cylinder 31, and a gap is provided between the covering plate 61 and the outer sieve cylinder 31 for the rotation of the shovel plate 33; furthermore, a plurality of inclined blowing pipes 64 are evenly distributed on the covering plate 61 and along the axial direction, and the blowing pipes 64 are inserted on the side wall of the covering plate 61, and one end of the air outlet is placed on the inner side of the covering plate 61, and the air outlet is away from the moving body 1, and the other end is connected to the air supply pipeline 63 of the first air pump 62, and the first air pump 62 is fixed on the moving body 1, and the air supply pipeline 63 is connected to the air outlet of the first air pump 62, and the air supply pipeline 63 is reinforced and connected to the moving body 1 through a supporting plate. When in use, the first air pump 62 compresses the air to deliver wind with a certain pressure to the air delivery pipe 63, and then the air delivery pipe 63 blows out the gas through the blowing pipes 64 at different positions, so that the gas with a certain wind force is blown toward the side of the outer sieve cylinder 31. When the shovel plate 33 carries the fruit but has not reached the notch 35 of the inner sieve cylinder 32, the shovel plate 33 passes through the air outlet of the blowing pipe 64, and the wind force blown out will blow up the lighter impurities (such as leaves, weeds, etc.) mixed in the fruit on the shovel plate 33, and due to the inclined setting of the blowing pipe 64, the wind direction blown out will blow out the impurities from the side away from the moving body 1, so that the fruit can be initially cleaned before entering the inner sieve cylinder 32, which is convenient for the subsequent cleaning of the fruit. In addition, the design of the covering plate 61 can also better assist the shovel plate 33 to fully transport the scooped fruits to the notch 35 of the inner screen cylinder 32, avoiding the fruits being thrown out during the rotation of the shovel plate 33, resulting in a reduction in the picking amount, thereby improving the picking efficiency.

[0056] See also Figure 3 and Figure 6 As shown, further, in order to improve the effect of removing impurities in the fruit, the collected fruit is cleaner. A plurality of screening holes 7 are evenly distributed on the shovel plate 33, and the screening holes 7 are used to screen out impurities smaller than the fruit on the shovel plate 33. When in use, when the shovel plate 33 scoops up the fruit from the ground, the screening holes 7 on the shovel plate 33 will be used to initially clean out a portion of small impurities such as soil blocks and gravel mixed in the fruit, so that the soil blocks and gravel can be more fully cleaned out during the subsequent cleaning, ensuring that the fruit transported to the collection box 2 is cleaner.

[0057] See also Figure 6As shown, in addition, in order to facilitate the shovel plate 33 to fully pick up the fruits on the ground and reduce the carrying of weeds and leaves on the ground, the end of the shovel plate 33 away from the outer screen cylinder 31 can be set to a rake-shaped structure, or the shovel plate 33 as a whole can be set to a rake structure, which can not only achieve the picking of fruits, but also reduce the carrying of impurities, so that the inclusion of impurities is effectively reduced at the beginning of fruit picking.

[0058] See also Figure 3 , Figure 7 and Figure 8 As shown, further, in order to make the fruits more cleanly collected in the collection box 2, the impurities in the fruits are effectively removed. A first impurity removal unit 8 is arranged on the mobile body 1, and the first impurity removal unit 8 includes a first conveying component, a dust collector 82 and a dust collecting plate 84. The first conveying component includes a driving module and a first conveyor belt 81, and the first conveyor belt 81 is installed on the mobile body 1 and is located between the outlet of the inner screen drum 32 and the collection box 2. Preferably, the first conveyor belt 81 is horizontally arranged, and a plurality of levers are evenly distributed on the belt surface of the first conveyor belt 81; thereby, the first conveyor belt 81 is powered by the driving module, so that the first conveyor belt 81 can carry the fruits to the collection box 2. Then, the dust collector 82 is fixed on the mobile body 1, and the dust collecting port of the dust collector 82 is connected to a dust collecting pipe 83; the number of dust collecting pipes 83 is the same as the number of dust collecting plates 84 and there is at least one. The dust collecting plate 84 is a hollow structure, and the cavity of the dust collecting plate 84 is connected to the dust collecting pipe 83. When installed, the dust collecting plate 84 is laid flat on the upper side of the belt surface of the first conveyor belt 81 and a gap is provided between the dust collecting plate 84 and the belt surface of the first conveyor belt 81 to ensure the passage of the fruit. The dust collecting plate 84 is provided with a plurality of dust collecting holes 85 on the side wall facing the first conveyor belt 81, and a limiting plate 86 is vertically fixed on the edge of the dust collecting plate 84 close to the outer sieve drum 31. When in use, the first conveyor belt 81 can convey the fruit conveyed from the inner sieve drum 32 to the collection box 2 for collection, reducing the manpower output, and in the conveying process of the first conveyor belt 81, the limiting plate 86 is first used to ensure that the accumulated fruit can be transported in a single layer, and then the dust collector 82 can be used to further remove small particles of impurities such as dust mixed in the fruit through the adsorption effect of the adsorption plate, so that the fruit is cleaner.

[0059] See also Figure 8 As shown, further, in order to make the fruits cleaner, a plurality of groups of bristles 9 are fixed on the side wall of the dust collecting plate 84 facing the first conveyor belt 81, and each group of bristles 9 is arranged along the width direction of the first conveyor belt 81. Preferably, the bristles 9 are made of soft rubber material, and during the transmission of the first conveyor belt 81, the bristles 9 can be used to better block and clean the impurities carried by the fruits, and the first conveyor belt 81 can be cleaned regularly.

[0060] See also Figure 7 , Fig. 9 and Fig.10 As shown, further, in order to make the fruits more cleanly collected in the collection box 2, the impurities in the fruits are effectively removed. A second impurity removal unit 10 is also arranged between the first impurity removal unit 8 and the collection box 2, and the second impurity removal unit 10 includes a second conveying component, a guide plate 103 and a second blowing assembly 104. The second conveying component also includes a driving module and a second conveyor belt 101, which is obliquely installed on the moving body 1, and the lower end of the second conveyor belt 101 in the oblique direction is placed on the lower side of the first conveyor belt 81, and the upper end in the oblique direction is placed on the upper side of the entrance of the collection box 2. A plurality of lifting plates 102 are evenly distributed on the belt surface of the second conveyor belt 101; the guide plate 103 is obliquely arranged between the second conveyor belt 101 and the entrance of the collection box 2; the second blowing assembly 104 is arranged on one side of the guide plate 103, and the second blowing assembly 104 is used to blow air horizontally to the fruits rolling on the guide plate 103. Preferably, the lower end of the guide plate 103 in the inclined direction is fixedly connected with an arc-shaped protrusion 11 along the width direction, and the arc-shaped protrusion 11 transitions to the guide plate 103 in an arc on the side facing the second conveyor belt 101; and an anti-slip pad layer 12 is laid on the upper side of the guide plate 103.

[0061] See also Figure 2 and Figure 7 As shown, further, the second blowing assembly 104 includes a second air pump 1041 and a plurality of shunt pipes 1043. When installed, the second air pump 1041 is fixed on the mobile body 1, and the output end of the second air pump 1041 is connected to a gas collecting pipe 1042; the gas collecting pipe 1042 is connected to a plurality of shunt pipes 1043, and the plurality of shunt pipes 1043 are distributed in steps along the inclination direction of the guide plate 103, and the air outlet end of each shunt pipe 1043 is connected to a blowing nozzle 1044, and the blowing nozzle 1044 is arranged in a trumpet shape. It is better to use the trumpet mouth structure to disperse the wind force blown out by the blowing nozzle 1044, so that the blown-down area is larger, and at the same time, it is also avoided that the wind force is too concentrated to cause some fruits to be blown out of the guide plate 103.

[0062] When the first conveyor belt 81 conveys the fruit to the side of the second conveyor belt 101, the fruit on the first conveyor belt 81 will fall onto the step formed by the belt surface of the second conveyor belt 101 and the lifting plate 102. In order to ensure that the fruit on the first conveyor belt 81 can fully fall on the lifting plate 102, it is preferred to obliquely set a transition plate between the first conveyor belt 81 and the second conveyor belt 101, so that the fruit can fully fall onto the lifting plate 102 along the transition plate. Furthermore, after the lifting plate 102 under the transmission of the second conveyor belt 101 runs to the upper end of the inclined direction of the second conveyor belt 101, the fruits will fall evenly onto the guide plate 103. At this time, due to the inclined setting of the guide plate 103, the fruits will roll along the guide plate 103 into the collection box 2, and other impurities have an irregular structure, which will produce a large friction with the anti-slip pad on the guide plate 103 and be blocked by the arc-shaped protrusion 11, which will fully reduce the flow of impurities into the collection box 2. At this time, starting the second opening and closing function will further blow out the impurities through the blowing nozzle 1044 on the diverter pipe 1043, ensuring that the fruits enter the collection box 2 more cleanly.

[0063] Among them, the second drive module and the first drive module can share the same set of drive systems, so as to facilitate the synchronous operation of the first conveyor belt 81 and the second conveyor belt 101, and can save costs. Preferably, the drive system can be composed of a motor 13, a pulley 14 and a belt 15, and two pulleys 14 are provided to be respectively mounted on the rollers at one end of the first conveyor belt 81 and the second conveyor belt 101, and the two pulleys 14 are connected by a belt 15, and one of the rollers is fixed to the output shaft 52 of the motor 13, so that the first conveyor belt 81 and the second conveyor belt 101 can be driven to rotate their respective connected rollers through the cooperation of the motor 13, the pulley 14 and the belt 15, so as to realize the synchronous operation of the first conveyor belt 81 and the second conveyor belt 101.
