[0002] At present, the main way to deal with the residual branches after orchard pruning in my country is to gather the pruned branches to the edge of the field and burn them. This treatment method not only wastes the original available resources, but also produces a large amount of smoke and dust that affects the environment. Especially in Xinjiang, where the climate is dry and precipitation is low, a large amount of smoke and dust is suspended in the air. The process of gathering the residual branches after pruning will also consume a lot of manpower.

[0003] Therefore, how to provide an orchard branch harvester that can automatically pick up, crush and collect broken branches in the orchard to improve the degree of agricultural mechanization automation, improve the efficiency of orchard branch processing, and reduce labor costs and labor is an urgent problem that technical personnel in this field need to solve. Summary of the invention

[0004] In view of this, the present invention provides an orchard branch harvester which can automatically pick up, crush and collect the broken branches in the orchard, so as to improve the degree of agricultural mechanization automation, improve the efficiency of orchard branch processing, and reduce labor costs and labor.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] A residual branch picking mechanism, wherein a picking assembly of the residual branch picking mechanism is installed in the picking chamber and arranged close to the residual branch feeding inlet, and a picking drive assembly of the residual branch picking mechanism is installed on the picking crushing machine housing and is transmission-connected to the picking assembly;

[0010] A residual branch crushing mechanism, wherein a crushing assembly of the residual branch crushing mechanism is installed in the crushing chamber, and a crushing drive assembly of the residual branch crushing mechanism is installed on the picking and crushing machine housing and the hanging frame, and is drivingly connected to the crushing assembly;

[0011] A strip collecting device, wherein the strip collecting devices are two and are respectively installed on the left and right sides of the picking and crushing machine housing and are both located in front of the residual branch feeding port;

[0012] A branch collecting vehicle, the front side of which is fixedly connected to the rear side of the picking and crushing machine shell, a branch collecting box is installed on the branch collecting vehicle, and the branch collecting box is connected to the branch discharge outlet through a branch conveying pipeline.

[0013] It can be known from the above technical scheme that compared with the prior art, the present invention discloses an orchard branch shredder harvester. When working, the suspension frame is connected to the suspension of the locomotive, and then the height of the suspension frame is adjusted according to the ground branch situation through the hydraulic suspension lifting device on the locomotive. Then the locomotive moves forward, and the strip collecting devices on both sides collect the scattered branches on the ground to the branch feeding inlet and integrate them into strips, so that the branches can enter the picking chamber through the branch feeding inlet. Then the picking component of the branch picking mechanism will transfer the branches into the crushing chamber, and the crushing component of the branch crushing mechanism will crush the branches in the crushing chamber. The crushed branches are directly thrown into the branch collection box through the branch conveying pipeline to realize the collection of branches. Therefore, the orchard branch shredder can realize the integrated operation of collecting branches, picking up and feeding, crushing, and collecting branches, which improves the degree of mechanical automation in agriculture, improves the efficiency of orchard branch processing, and reduces labor costs and labor.

[0014] Furthermore, the residual branch picking mechanism comprises:

[0015] A hydraulic motor, the hydraulic motor being fixed to one side of the top end of the picking and crushing machine housing;

[0016] A picking-up feeding shaft is rotatably connected in the picking-up cavity and arranged near the residual branch feeding inlet. One end of the picking-up feeding shaft is transmission-connected to the driving end of the hydraulic motor via a first transmission mechanism. A plurality of picking-up feeding knives are uniformly sleeved on the outer wall of the picking-up feeding shaft. The picking-up feeding shaft and the picking-up feeding knives constitute the picking assembly. The hydraulic motor and the first transmission mechanism constitute the picking driving assembly.

[0017] The beneficial effect of adopting the above technical solution is that the hydraulic motor drives the picking and feeding shaft to rotate through the first transmission mechanism, and then drives the picking and feeding knife to rotate. The picking and feeding knife pushes the residual branches at the residual branch feeding entrance into the crushing chamber to realize the residual branch picking operation.

[0018] Furthermore, the picking and feeding shafts are two arranged up and down, and both are arranged close to the residual branch feeding entrance.

[0019] The beneficial effect of adopting the above technical solution is to improve the picking effect of broken branches.

[0020] Further, each of the picking and feeding knives comprises:

[0021] An intermediate mounting plate, wherein the intermediate mounting plate is sleeved and fixed on the picking and feeding shaft;

[0022] There are two picking lug paddles, which are integrally connected to the opposite sides of the middle mounting plate respectively, and one side of the two picking lug paddles is a branch plucking surface, and a plurality of plucking teeth are provided on the side of the picking lug paddle opposite to the branch plucking surface.

[0023] The beneficial effect of adopting the above technical solution is that when the picking lug paddle rotates clockwise, the prying surface prys the residual branches into the crushing chamber, and at the same time, the residual branches located in front of the prying teeth are easily driven into the crushing chamber by the prying teeth. Therefore, by providing the prying surface and the prying teeth, the picking effect and efficiency of the branches are greatly improved.

[0024] Furthermore, the residual branch crushing mechanism comprises:

[0025] A gearbox, the gearbox is fixed to the top of the picking and crushing machine housing, the input shaft of the gearbox is connected with a universal joint, the universal joint is connected to a transmission shaft installed on the suspension frame, and the transmission shaft is connected to a power output shaft of the locomotive;

[0026] A crushing shaft, the crushing shaft is rotatably connected in the crushing chamber, and one end of the crushing shaft is transmission-connected to the output shaft of the gearbox via a second transmission mechanism, a plurality of crushing moving knives are fixed on the outer wall of the crushing shaft, the crushing shaft and the crushing moving knives are the crushing assembly, and the gearbox, the universal joint, the transmission shaft and the second transmission mechanism are the crushing drive assembly.

[0027] The beneficial effect of adopting the above technical solution is that the power of the locomotive is transmitted to the universal joint through the transmission shaft, the universal joint transmits the power to the gearbox, the power is transmitted to the fan shaft through the speed increaser of the gearbox, and then drives the crushing shaft to rotate, and the crushing moving knife crushes the branches in the crushing chamber. The crushed branches are directly thrown into the crushed branch collection box through the crushing branch conveying pipe under the action of the centrifugal force of the crushing moving knife on the high-speed rotating crushing shaft.

[0028] Furthermore, a crushing tooth plate is fixed on the inner cavity wall of the crushing cavity, and a plurality of crushing fixed teeth are fixed at intervals on the side of the crushing tooth plate facing the crushing shaft.

[0029] The beneficial effect of adopting the above technical solution is that the fixed crushing teeth cooperate with the movable crushing knife to directly rub and hammer the branches in the crushing chamber, thereby achieving rapid crushing and good branch crushing effect.

[0030] Furthermore, the two strip collecting devices each include:

[0031] A cantilever support, the fixed end of the cantilever support is fixedly connected to one side of the front end of the pick-up shredder housing;

[0032] A stubble gathering wheel, the stubble gathering wheel is rotatably connected to the cantilever end of the cantilever support, and a plurality of stubble elastic bars for gathering scattered stubble towards the stubble feeding port are uniformly fixed on the rim of the stubble gathering wheel.

[0033] The beneficial effect of adopting the above technical solution is that when the locomotive is moving forward, the stubble gathering wheel rotates, and the rotating stubble elastic bars gather the scattered stubble into a strip shape towards the stubble feeding port.

[0034] Furthermore, the two stubble gathering wheels are arranged in a V shape, and the V-shaped opening faces the advancing direction of the locomotive.

[0035] The beneficial effect of adopting the above technical solution is that it is beneficial to gather the stubble towards the stubble feeding port.

[0036] Furthermore, the stubble elastic bar is in a V shape, and the V-shaped opening is arranged facing the advancing direction of the locomotive.

[0037] The beneficial effect of adopting the above technical solution is that when the stubble gathering wheel rotates, the stubble elastic bar at the bottom of the stubble gathering wheel contacts the ground and is compressed. When the compressed stubble elastic bar leaves the ground, the stubble elastic bar returns to its original state, and the elastic force generated by it deflects the stubble on the ground towards the stubble feeding port, thereby realizing the gathering of the stubble towards the stubble feeding port.

[0038] Furthermore, a push oil cylinder for pushing the shredding collection box to turn over is installed on the chassis of the shredding collection vehicle. The cylinder barrel of the push oil cylinder is hinged to the chassis of the shredding collection vehicle, the telescopic end of the push oil cylinder is hinged to the bottom end of the shredding collection box, and a shredding unloading door is hinged on the rear side box wall of the shredding collection box.

[0039] The beneficial effect of adopting the above technical solution is that when the fruit branches in the shredding collection box reach a certain amount, the locomotive is moved to the designated stacking position, the shredding unloading door is opened, the push oil cylinder pushes the shredding collection box to tilt at a certain angle, and the internal shredded branches slide to the ground under the action of their own weight, realizing the purpose of automatic unloading, without manual unloading, saving labor and having high unloading efficiency.
