Description

Technical Field

[0001] This utility model belongs to the field of harvesting equipment, specifically relating to a harvesting extension rod device that can be used in harvesting. Background Technology

[0002] Fruit harvesters are tools used for picking fruits and other produce. Compared to manual harvesting, using harvesters can improve harvesting efficiency. With the popularization of mechanization, some fully automatic harvesting machines have also emerged. Although these machines are even more efficient, full mechanization during the harvesting process may damage the fruit or result in incomplete harvesting, leading to waste. Fruit harvesters are a suitable harvesting method between manual and mechanical harvesting, and they remain practically useful in situations involving special fruits or in terrain where machinery cannot reach.

[0003] However, existing harvesters are designed based on the shape and characteristics of the fruit to be harvested. When using them, workers may have to bend over for a long time or may not be able to reach wider fruit trees. Therefore, it is necessary to design an extension rod to improve harvesting efficiency and reduce the labor intensity of harvesting. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a harvesting extension rod device that can extend the use of the harvester and allow adjustment of the harvester's pitch angle.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A harvesting extension pole device includes a pole assembly, a fixing member, and a connecting member. The connecting member is connected to the pole assembly. The fixing member is pivotally connected to the connecting member, and the axis of pivoting of the fixing member is perpendicular to the pole assembly, i.e., the axis is approximately perpendicular to the length direction of the pole assembly. The fixing member is detachably connected to a harvester. By pivoting the fixing member relative to the connecting member about its axis, the pitch angle of the harvester can be adjusted to meet harvesting requirements.

[0007] By adopting this technical solution, on the one hand, the harvester can be extended using this device to improve the harvesting experience and efficiency; on the other hand, the tilt angle of the harvester is adjustable and can be adjusted as needed to meet specific requirements.

[0008] According to the above-described harvesting extension rod device, the fixing member includes a first connecting arm, the connecting member includes a second connecting arm, and a first fastener passes through the first connecting arm and the second connecting arm to form a pivotable connection.

[0010] According to the above-mentioned harvesting extension rod device, a nut is embedded in the first connecting arm, or a nut hole for nut installation is provided on the outer side of the first connecting arm, so as to pivotally connect the first connecting arm and the second connecting arm.

[0011] According to the above-mentioned harvesting extension rod device, the first connecting arm and the second connecting arm are respectively provided with a first toothed ring and a second toothed ring, and the first toothed ring and the second toothed ring are arranged in the circumferential direction.

[0012] According to the above-mentioned harvesting extension rod device, both the first toothed ring and the second toothed ring are composed of helical teeth, thereby allowing manual rotation to adjust the angle and limiting rotation during normal use.

The fixing body includes a fixing plate and a first connecting arm. At least two clamping arms are also provided on the fixing plate. A clamping slot is formed between the two clamping arms. A third through hole is provided in the clamping arm. The second fastener passes through the third through hole and is connected to the fixing block to clamp and fix the handle of the harvester between the fixing body and the fixing block.

[0014] According to the above-mentioned harvesting extension rod device, the first connecting arm and the clamping arm are respectively disposed on the upper and lower sides of the fixing plate, and the first connecting arm and the second connecting arm are respectively disposed on one side, that is, on both sides of the cross section of the rod.

[0025] First rod 111, second rod 112, grip 113, first telescopic adjustment member 114, second telescopic adjustment member 115.

[0028] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model will be described in detail below with reference to certain specific embodiments.

[0029] like Figure 1-6As shown, a picking extension pole device 10 can be installed on the handle 201 of the picker 200 to extend the picker 200, facilitating picking operations. This avoids the need for prolonged bending when picking low-lying fruits, or the inability to reach distant fruits in a wider picking area. Preferably, this picking extension pole device 10 is suitable for use when picking blueberries. Extending the blueberry picker with this device simplifies the intensity of the picking operation. The appearance and structure of the picker 200 are known and can be referenced to the blueberry picker shown in CN308694633S, and will not be described further.

[0030] like Figure 1-2 As shown, the harvester 200 consists of a rod assembly 11, a fixing member 12, and a connecting member 13. The fixing member 12 is connected to the rod assembly 11 via the connecting member 13. The fixing member 12 allows the harvester 200 to be fixed thereto, and the fixing member 12 and the connecting member 13 are pivotally connected, allowing the angle of the fixing member 12 to be adjusted as needed. The axis 100 is generally perpendicular to the lower part of the rod assembly 11 (the lower part refers to the straight portion at the lower end of the rod assembly 11; in other embodiments, it is also feasible to make the entire rod assembly curved). Therefore, by adjusting the pivot angle of the fixing member 12 about the axis 100, the front end of the harvester 200 can be horizontal, tilted upwards, or tilted downwards, i.e., the pitch angle of the harvester can be adjusted. Figure 1 The direction indicated by the double-headed arrows is to meet the requirements for insufficient harvesting and use.

[0031] In this embodiment, the fastener 12 includes a fastener body 121, on which a fixing plate 122 and a first connecting arm 123 are provided. The first connecting arm 123 is formed protruding on the upper surface of the fixing plate 122. The fixing plate 122 is used to clamp and fix the handle 201 by a fixing block 141 and a second fastener 142. The first connecting arm 123 is provided with a first through hole 124, and a corresponding second through hole 133 is provided on the connector 13. The first fastener 134 passes through the first through hole 124 and the second through hole 133 to pivotally fix the fastener 12 and the connector 13.

[0032] Preferably, a nut (not shown in the figure) is embedded in the first connecting arm 123, and the first fastener 134 passes through the second connecting arm 132 and the first connecting arm 123 and is threadedly connected to the nut to pivotally fix the fastener 12 and the connector 13. In other embodiments, a nut hole for mounting a separately installed nut may be recessed on the outer side of the first connecting arm 123, and the first fastener 134 passes through the second connecting arm 132 and the first connecting arm 123 and is threadedly connected to a nut provided in the nut hole.

[0033] To enhance the locking strength between the fastener 12 and the connector 13, a first toothed ring 120 and a second toothed ring 130 are respectively provided on their contact surfaces. Both toothed rings include several toothed blocks arranged in a circumferential direction, which can mesh with each other to increase the locking force of pivoting. Preferably, both the first toothed ring 120 and the second toothed ring 130 are composed of helical teeth, that is, both sides of each toothed block are inclined surfaces. This allows for separation during relative rotation through the guiding effect of the inclined surfaces, thus allowing manual relative pivoting. At this time, the tightness of the first fastener 134 cannot be too strong. The first fastener 134 needs to be loosened by a certain distance before the aforementioned guiding rotation can be allowed. This is technically understandable and expected.

[0034] In this embodiment, the first connecting arm 123 and the second connecting arm 132 of the connector 13 are each located on one side to simplify space, achieve a compact structure, and create an aesthetically pleasing appearance. The connector 13 includes a cylindrical connecting body 131, and the second connecting arm 132 is semi-cylindrical and protrudes below the connecting body 131. Figure 6 As shown.

[0035] Preferably, the rod assembly 11 is a telescopic rod, consisting of a first rod 111 and a second rod 112. A first telescopic adjustment member 114 is provided on the first rod 111, preferably made of ball bearings. The second rod 112 is hollow internally, and its sidewalls are provided with several second telescopic adjustment members 115 at intervals. Each second telescopic adjustment member 115 is a ball bearing hole. The length of the rod assembly 11 is adjusted by fitting the first rod 111 into the hollow cavity of the second rod 112 and by fixing the ball bearings in different ball bearing holes. Preferably, a handle 113 made of flexible material is also provided at the end of the second rod 112 for comfortable grip.

[0036] like Figure 3-4 As shown, to fix the handle 201 of the harvester 200 to the fixing member 12, a clamping arm 127 protrudes below the fixing plate 122 of the fixing body 121. A clamping slot 126 is formed between two adjacent clamping arms 127, and the width of the clamping slot 126 is suitable for at least partially accommodating the handle 201. A fixing block 141 is located below the fixing body 121. A third through hole 128 and a fastening hole 143 are correspondingly provided on the clamping arms 127 and the fixing block 141. A nut (not shown in the figure) is embedded in the fastening hole 143. A second fastener 142 passes through the third through hole 128 and is threaded into the fastening hole 143, thereby clamping and fixing the handle 201 from both the top and bottom directions via the fixing body 121 and the fixing block 141. Preferably, the surface of the fixing block 141 is provided with a soft material to enhance the fixing fit and increase the friction.
